Doors and windowssecurity seals stay more comfortable environment !

The hotel industry as one of the three pillars of the tourism industry , the upcoming May Day holiday is bound to reach a peak passenger flow. So , whether it is a business hotel, Inn or a luxury hotel also , before the advent of the peak are doing the appropriate preparations. A rare opportunity , brutal competition , how to stand out in many hotels , win more customers become the hotel industry are thinking about the problem.

We know that to go away on business or pleasure , a basic requirement for the hotel is clean and tidy ,Fixed Length plastic seal the other is quiet. After all, the hotel 's main function is to provide travelers a comfortable seating space walkers , but not all around the hotel is so pleasant and comfortable environment , a variety of factors have led to the hotel's location is not the same , some hotels around the noisy bustle , closed the window also to no avail , the corridor up to and fro footsteps , talking clearly hear the sound of the room so that guests sleep well , also affect the reputation of the hotel . Therefore, many hoteliers will first sights soundproofing industry , the use of sound and reasonable measures to compensate for the noise nuisance caused .

Dry gas seals used in the centrifuge

Improvement of the mechanical seal
Centrifuge traditional mechanical seals, mechanical seals are the advantages of simple structure, mature technology, machining accuracy is not required; drawback is that life is short, power consumption, there must be a liquid medium to lubricate and cool the sealing surface, the production process parameter fluctuations great seal. Since the operation centrifuges, mechanical seal life has been very short, only five months longest, replace the mechanical seal needs 28h, seriously affecting production. And after the mechanical seal (referred mechanical seal) failure is leaking liquid hexane, hexane is flammable, explosive media, not only the existence of a significant security risk, but also caused serious pollution to the environment. Based on this, we decided to change it to dry gas seal, to enhance economic efficiency and eliminate security risks. Dry gas seal is the most advanced form of a non-contact seal, mainly by the rotating ring, stationary ring, ring, spring, spring seat and sleeve components.
After rotating ring sealing surface grinding and polishing process, and the processed fluid at the dynamic pressure grooves, Figure 2. Dry gas seals rotary ring is rotated, the dynamic pressure of the sealing gas is sucked into the tank, the throttling effect of the sealing weir, into the sealing surface of the gas is compressed under the action of the gas pressure, the sealing surface is open, the gas flow forming a thin gas film between the two sealing surfaces and a thickness of 3 ~ 5um,high security cable seals when the reaction force together with aerostatic air film and the formation of the spring force is equal to the thickness of the air film is very stable, thus ensuring the seal reliability.

We analyze the structure of the centrifuge, decided not to change the device structure, the use of double-end dry gas seal, the same size as the original seal size, and a similar structure, easy to install, see Figure 3. Taking into account the process medium plastic powder, using hexane for cleaning sealed chamber for cleaning. Dynamic pressure dry gas seal ring groove machined end face, using tungsten carbide ring (WC) material, which has a high surface hardness, wear resistance, thermal conductivity coefficient, etc.; static ring using impregnated graphite material, which has high strength, good lubricating properties and high temperature, etc. from.
Seal gas is nitrogen, provided by external network, the maximum pressure is 0.7MPa, the normal operating pressure of 0.5-0.6MPa, the minimum pressure of 0.4MPa, the nitrogen flow is greater than l0 standard m3 / h.
0.7MPa nitrogen is passed through the filtration unit under reduced pressure to 0.5 MPa, into the sealed chamber through a flow meter. To prevent the pipe network in the nitrogen pressure fluctuations for emergency spare bottle with nitrogen gas source, alternate air source can supply 2h. Dry gas seal leakage from the flow meter showed normal operation, the nitrogen leak kept within a stable range,identification cable ties if the leakage continues to increase, the seal chamber pressure will drop, when the pressure drops Bian 0.3MPa, interlock parking to Centrifuge ensure safety. From the actual operation situation, the nitrogen pressure in the 0.5MPa, to ensure the good functioning at this time, nitrogen consumption was 0.48 standard m3 / h, less than the design of a standard m3 / h.

These aspects of mechanical seals how to do these problems

Graphite ring ( or ceramic ) fracture

Correctly handle automotive sealing problems

Automotive sealing strip (automobile rubber seal strip) is one of the important parts car , widely used in doors, windows , body , seats, sunroof, and other parts of the engine compartment and trunk , with a waterproof, sealing, noise , dust , frost , shock absorption , warmth and energy conservation an important role. It must have a strong tensile strength , good flexibility , but also good heat resistance and resistance to aging. In order to ensure the fastening strips and profiles , strips and profiles section structure dimensions must match .
Fix the sealing flange in the vehicle door , the seal should be noted that repair damaged flanges , flange accurately restore the original shape. To carry out the repair after the door seal inspection, the inspection method is: put a hard disk in a sealed position, shut the door , and then pull the paper , according to the Rally to determine the size seal is good . If the force required to pull the paper too much explanation sealed tight, this will affect the doors close properly , and also due to deformation of the seal over the Omo faster mourning for sealing performance ; if the force required to pull the paper too small , indicating bad seal doors wind does not often appear rain phenomenon. When replacing the door must pay attention to the inner and outer door panels in a new office painted folding plastic flange bite and put some punch hole left when the small craft with the base tape blocked .
In the repair of automotive line , should all body holes , holes worn harness ring is mounted at the place, not only because these seals from the seal, but also play a protective role in the harness . If the seal is damaged or harness can be rotated or ran seals , replace the metal security seals, and compares it with the body holes , hole assembly firmly secure the harness is good .
In the window glass is damaged , changing with the same curvature as the original glass window glass , while the glass to check the guide groove and seal for damage. Because windows often reply after repair is less than its original shape , therefore , when in addition to ensure easy pulling or lifting the window glass , but also pay attention to the window glass in the windows closed after four weeks of the seal.
In changing the roof , the roof should be in place around the lamination coated conductive sealant, after a good to be welded seams in the water tank and folding over the painted plastic , which not only helps the body seal , prevents the body due to more water to produce the weld flange early rust. Assembling the door when the door below the window paste an entire inner panel sealing barrier film , if not forming a seal barrier film , you can use ordinary plastic instead of paper , and then affix the seal spacer film compaction , and finally for interior panels production assembly .
When replacing the entire body , in addition to each of these projects should be completed outside , but also in the lap portion of the weld joints on both coated with sealant layer thickness should be about 1mm, and may not have virtual sticky layer , bubbles and other defects ; should be at the Flap Flap special plastic coated ; across the floor surface and the lower surface of the front cover should be coated 3mm-4mm elastic coatings and anti-corrosion coating ; on the floor surface and the front elevation to paste the plate surface noise, heat , vibration damping film , colored cable ties then covered insulation blankets block , and finally covered with carpets or fitted with decorative flooring. These measures can greatly enhance the sealing and the vehicle speed slows down corrosion of the body , but also can greatly enhance comfort.

Conical shaft for the mechanical seal of the swing

Shaft swings may occur depending on the maximum pump heads ( the bottom one ) fluorine resin bearing radial clearance . According to the manufacturer 's standard , 9LDTN type condensate pump bearings allow maximum use of fluorine resin gap 0.4 mm, taking into account the fluorine resin bearing wear will not damage after mechanical seal , based on past experience overhaul , whichever heads fluorine resin bearing radial clearance to 2 mm. Principles calculations based on similar triangles , the mechanical seal shaft runout limit value of 0.24 mm, and then consider rolling under its own motor radial clearance is set to 0.1mm ( for 6226 bearing is damaged in terms of the gap ) , then mechanical shaft seals can get maximum runout of 0.34 mm. The selected mechanical seal allows runout of 0.5 ~ 0.7 mm, it will not damage the shaft for mechanical seal conical swing .

Transformation is due to the choice of cartridge single mechanical seal , installation is relatively simple and does not require any transformation of the pump , mechanical seal less work . However, in the transformation process involves the following considerations :
a) Check the condensate pump original packing sleeve outer periphery of ovality , elliptical too large to be replaced. Because mechanical seal sleeve must set this sleeve , with the Department by its O-ring indicative seal, sleeve oval spend much effect on the O-ring and sleeve contacts , causing leaks here .
b) packing sleeve and the shaft seal must be reliable without leakage, if packing between the sleeve and the shaft seal leakage , condensation will also affect water quality and vacuum unit .
c) the original packing chamber condensate pump outer face flat on the lathe processing needs . In order to ensure the mechanical seal stationary ring gland with a combination of good surface contact , it is best to fill up the cavity outer face flange portion for turning .
d) Install the mechanical seal , in a still sealed position using a good quality sealant to prevent leakage.
e) mechanical seal is in place, the pump and the motor must be in good and installed on the coupling after a fixed stationary ring and ring gland , and finally will be positioned to take the card to open . Otherwise , couplings and joints for adjusting the pendulum will cause partial radial and axial elevation will not only affect the mechanical seal static ring sealing surface contact , but also changes the mechanical seal tight static ring contact force, contact tightening force burned mechanical adjustable length seal over the General Assembly .
f) mechanical seal return pipe must be connected back to the pump inlet . Because the upper guide bearing a relief bore seal leakage , it serves to ensure the mechanical seal chamber pressure of not more than 490 kPa in effect, while the return pipe connected to a lower pressure , they may form a flow in order to promptly the movement of the mechanical seal sealing surface due to friction heat away .

Hydraulic system factors affecting the performance of seals

Hydraulic oil for hydraulic drive system as the working medium , from the energy transfer , conversion and control role, while also playing the various components within the hydraulic system for lubrication , corrosion , rust and cooling effect.
Hydraulic system plays a seal to prevent leakage of fluid from the joint surfaces , maintaining the pressure , to maintain the role of energy transfer or conversion .
Sealing material used at home and abroad are mostly polymer elastomer , there are a number of special conditions, the use of plastic and various metals. But regardless of what kind of material , should have the following properties:
1 , with some mechanical and physical properties : such as tensile strength , elongation strength , elongation ;
2, there is a certain degree of flexibility, hardness fit and compression set ;
3 , the working media , not prone to swelling , decomposition , hardening ;
4 , wear, there are some anti -tear properties ;
5 , high temperature, low temperature aging .
However , there is no numbered seals sealing materials include all of the above properties , the need to work environment, such as temperature , pressure, media and sport mode to select the suitable sealing material , and through the development of materials with recipe to meet certain requirements . Or the use of composite materials or a combination of two or more structures in the form of play to their strengths, to achieve more comprehensive results.
Seal formation : dynamic seal is divided into non-contact seals and contact seals . Non-contact seal mainly a variety of mechanical seals , such as: graphite packing ring , floating ring seals ; rubber composite seals and rubber seals belong portfolio contact seals , relying on filling in a sealed chamber in the pre- compression force , leakage channel blocking sealing effect is obtained . Seals used in hydraulic systems are mostly static seal ( seal ) , reciprocating seals ( piston, piston rod plastic seals seal ) and rotating seal .
Factors affecting the sealing effect : seal structure selection and film formation , pressure, temperature , material compatibility , dynamic sealing contact with the working surface of the material, hardness , geometry, surface finish .

Under high pressure mechanical seal

Under high pressure mechanical seal
Mechanical seals operating pressure exceeds 4 ~ 5MPa that belong to high-pressure sealing range . In the high-pressure conditions, due to the seal faces than the pressure value is too large , causing the face , fever, thereby undermining the film formation , resulting in abnormal wear . High friction can also make deformation and rupture. High pressure seal generally a balanced structure, so that the end than the pressure in an appropriate range . But taking into account the reliability of sealing balance coefficient increases can not be unlimited , and thus in some cases despite using a balanced structure, but may still be greater than the pressure face . Balanced structure alone is difficult to meet the requirements , this situation can be multi- end mechanical seal or controlled membrane mechanical seal.
Second, the high temperature mechanical seals
Generally, the medium temperature exceeds 120 ℃ is considered to be heat-sealed . At this time the main problems the mechanical seal are:
( 1) Since the friction face temperature, resulting vaporized film between the seal faces , the friction coefficient increases, increased wear , temperature increase, the sealing ring thermal deformation or thermal cracking and failure ;
( 2 ) The secondary seal mechanical luggage seals materials are generally rubber or PTFE , because for a long time in a hot environment , easy to aging and decomposition , resulting in seal failure ;
( 3 ) high temperature mechanical seal is easy to produce an elastic member and creep fatigue , failure of the seal ;
( 4 ) high-temperature corrosion of metallic materials will intensify and shorten the life of the mechanical seal .
To ensure mechanical seals in high temperature environment to work properly, you can take the following measures.
1 to increase the cooling mechanical seal flushing device .
2 Select the temperature of the material , depending on the operating temperature used different materials. Nitrile rubber upper temperature limit is 80 ℃, silicone rubber and fluorine rubber of 200 ℃, PTFE as 250 ℃.
In addition, the mechanical seal multi -metallic friction material impregnated with graphite , so they will have different operating temperature based on selection of different types of impregnated graphite . General Baptist babbitt graphite suitable temperature range is less than 150 ℃, resin-impregnated graphite temperature range of 170 ~ 200 ℃, leaching of copper, aluminum, lead and graphite at less than 400 ℃ working conditions. Ring components should be used wherever possible expansion coefficient similar material to prevent high temperatures ring and ring seat loose connection.
3 Select the metal bellows mechanical seal. Metal bellows seal used in recent years in many high temperature sealing , and achieved good results. In this kind of mechanical seal , the metal bellows mechanical security seals replaces the ordinary in spring , eliminating the need for secondary seal ring , ring compensation is not required to overcome the friction and wear of the shaft , so use at high temperatures , are generally able to achieve good results.

Pump Failure introduce dynamic seal

Core Tip: pump seals are soft packing seals , oil seals , labyrinth seals , spiral seals, dynamic seals and mechanical seals.
Prevent the working medium from leaking out of the pump or to prevent impurities or outside air intrusion into the pump means or measures known internal seal medium to be sealed is generally liquid, gas or dust .
Causing leakage for two main reasons : First, there is a gap sealing surface . Second, the pressure difference on both sides of the sealing parts , to eliminate or reduce any of the factors that can prevent or reduce leakage , to achieve the purpose of sealing . Pressure pump design and the use of pressure is an objective can not be reduced , so that the pump is sealed to the solution to eliminate or reduce the gap between the seal faces . Such a gap includes a gap between the sealing surface and the sealing means within the gap Bunsen .
Mechanical seals
Modern shaft seal mechanical seal is the main method , though use of it is not easy to achieve completely leak , but the reach of tiny , it is perfectly acceptable amount of leakage is entirely possible. However, the operation of the pump , but often embarrassing situation, then the mechanical seal failure because what is it ?
1, the mechanical seal material selection inappropriate. Mechanical seal material and the transmission medium does not match. In operation, the sealing element will soon be corrosion, dissolution or wear , thus losing the sealing capability. Therefore, according to the nature of the transmission medium and the choice of the mechanical seal material is to ensure its sealing function and the normal life of the prerequisites.
2 , the mechanical seal flush condition does not meet the design requirements. In conveying easy to crystallize or fine particles of the medium , there must be a certain pressure and a certain flow of fluid to wash , or their crystals or particles will accelerate the sealing wear and affect the sealing of worn automatic compensation leak. Therefore, according to the nature of the transmission medium not only to configure the appropriate flushing lines , but also to install a monitoring and regulation instruments and devices to ensure that fluid pressure and flow to meet the design requirements, in order to maintain the normal operation of the mechanical seal , which is often overlooked by users .
3 , each of the mechanical seal can withstand the pressure is limited , due to the seal chamber pressure measurement are not allowed, resulting in the seal chamber pressure exceeds the mechanical seal can withstand the pressure of the leak , is a common sealing one reason for failure .
4 , the mechanical seal operating temperature can not exceed the specified value. In the design of a cooling circuit , often due to insufficient flow of the cooling medium leaving the cooling effect is reduced ; without the cooling circuit design, the numbered seals cavity often as harbored in the air and cause mechanical seal dry friction condition. In both cases, the movement of the mechanical seal sealing temperature is too high and accelerated wear, resulting in seal failure.
5 , the use of a single spring mechanical seals ignored when spring pump rotor rotation direction and the direction of rotation correct combination also occurs . Or design without instructions or assembly negligence , failed to do so because of the rotation of the rotor mechanical seal leaving but on the contrary increase the spring force , resulting in the ring and stationary ring friction pairs formed insufficient pressure leak .
6 , bearing severe wear or damage , so that axial movement of the shaft produce severe , but also one of the reasons mechanical seal leakage . With the scientific and technological development, new seals and sealing materials , emerging forms , which is bound to the pump seal technology have a direct impact and promoted. Long life, zero leakage pump products in a growing number of occasions to get promotion and application.
Oil seals
Self-tight seal is a lip fixed length plastic strap seal , its simple structure , small size , low cost , easy maintenance, resistance torque is small, both to prevent media leaks , but also to prevent external intrusion of dust and other harmful substances , but also to wear have a certain ability to compensate , but the impatience high pressure, it is generally used in low pressure applications. Seal should be installed in the manufacturing precision of h8 ~ h9, the surface roughness of 1.6 ~ 0.8μm and after surface hardening treatment of the shaft . Sealing medium should not contain solid particles and impurities , which will cause rapid wear of the shaft seal and leaving the seal failure.

How to choose the cable sealing modules

1 The right choice of supplier
Choice of supplier , you should choose a professional cable glands module suppliers , preferably in a cable gland for the main business activities of the manufacturers . Manufacturers should have some experience in industrial applications , understanding of the product market applications. The current market was mixed good and bad cable glands , especially the large number of dealers on the network information posted to our choice of suppliers to bring a certain degree of difficulty.
The author believes that an excellent cable sealing module manufacturers should have the following points , A. Cable sealing modules are its main business ; B. Qualification sound and stability office space, not just a few information posted online , casual leave a contact ; C. independent company website and product physical map , a lot of other company 's products stolen map ( or PS pictures ) , virtually no product and service capabilities ; D. able to provide customers a complete professional CAD drawings and quotes , rather than simply a casual quotations ; E. and customer should have good communication skills , customer product selection and design rationalization proposals , of course, this requires some practical experience .
2 The right choice of products
Correct choice of products, should pay attention to the following aspects:
2.1 Module options: module is divided into 30 mm long and 60 mm in length both in different lengths and maybe also the entire thickness of the sealing device . Thus, the general run cable through the cabin deck , cables through walls and other heavy objects selected 60 mm long modules. The cable through the cabinet or other thin object, generally choose 30 mm long modules , while the entire sealing device is thin and light .
2.2 sealing frame choice: sealing frame is determined by the strap seals modules with different specifications and number of modules determines the appropriate sealing frame . Across the deck and the cabin walls and other objects should be selected 60 mm thick frame , materials generally have two kinds of low carbon steel and stainless steel . Recommended depending on the application environment choose a different frame materials. Recommended to choose the stainless steel frame , because the general cable sealing modules are outdoor or indoor environments outside connections, generally dark and damp or in sunlight exposure . Once the sealing frame with rust corrosion is occurring, will directly affect the performance and life of the sealing module , and seriously affect the whole sealing means sealing protective effect.
2.3 clamping block and the spacer plate material selection : General cable sealsupplier in the clamping block and compartment plate material on both stainless steel and mild steel in both materials can be selected . I do not recommend choosing low- carbon steel clamping blocks and spacer plates, because both kinds of material cost difference is not great , but life is very different , do not lose the greater.
2.4 The use of grease : It is recommended strict accordance with product installation instructions to use grease , many times in order to improve the efficiency of workers in trouble , do not use or less use grease, actually greatly affected the overall sealing means sealing effect .
2.5 About Installation tools: general project is not recommended. Engineering projects larger than recommended a compactor on it, only in the maintenance and reconstruction of puller only be used to time . Many manufacturers generally put a full installation tool as essential goods sold to customers , the actual increase customer acquisition costs .
About aside : Under normal circumstances proposed to set aside 30-40 % , of course, if the project is implemented in phases necessary special consideration. Also do not recommend the use of solid module as set aside , because this part of the procurement cost savings temporarily , but the actual change is the need for secondary procurement, not only a waste , and increased costs.

Renovation and floating seal seals

Seals transformation, instead of floating seal comb labyrinth seal modified to composite turbine in the power sector reform on the bearing housing seals for example, simply use the outer ring and the inner ring to replace the original floating inside block, other structure unchanged , maintaining the original assembly relationships, convenient and reliable. Specific transformation, according to the original comb truck seal assembly space, the actual operating conditions and parameters, use of different materials and different types of floating seal, ensuring design and production of each set of products are "tailored" to resolving user most want to solve the problem.
Application: dehumidifier, air conditioning, and other special moves. FX composites floating floating seal ring using a special composite material and scientific formula sintering, a lightweight, abrasion, temperature, self-lubricating characteristics for various low-temperature lubrication medium and small sized cooling medium dynamic plastic strap seals.
A resistance to media: strong resistance to steam, oil and chemical resistance. Dielectric properties, not easy to aging;
2 can be self-lubricating: low coefficient of friction and self-lubricating properties, even in the dry mill when it will not hurt axis;
3 low expansion: in the temperature range, even with a high temperature dimensional stability can be maintained.
4 high damping: a strong damping performance, improve the smooth running

Rubber seals manufacturing enterprises should focus on brand awareness

Rapid economic development has brought the automotive industry, and other machinery and other major downstream industries increased investment in fixed assets, the domestic market demand for security seals manufacturing industry provides huge market space.
Rubber seals may be small, but in national economic development plays an important role in national defense, chemical, petroleum, coal, transportation and machinery manufacturing and other industries based parts and accessories. In recent years, with the rapid economic growth, rubber seals manufacturing industry has maintained double-digit growth.
According to statistics, China's rubber pull tight seals manufacturing enterprises above designated size (diameter according to the National Bureau of Statistics, the sales income of 500 million yuan) realized an industrial output value of nearly 80 billion yuan, an increase of more than 25%.

Car glass sealing strip is sandwiched self solution

I'll give you a simple solution, I have successfully solved the problem, the fact that it is feasible, you may wish to try:
1: First the glass security seal in the case does not clip shut, a person fix on two individuals to cope with it, the simplest way is to use the card, or we carry identity cards, driving license and so hard on the line card in off the glass when the attention to the position of the clip seal Xiecha card into it, when the glass is completely closed after pull out the card, so the seal will not get stuck,
2: then use the hair dryer to soften the hot air to barrier seals  he folds flat with your fingers, of course, a relatively long clip was a bit longer and let the seal natural cooling, generally not very serious one can solve the problem anymore more time to do more than once repeated folds can also solve the problem, we go and try it!
