Wear of the pump bearings and seals resistant to solutions

( A ) problem : support bearing severe wear . Try a number of different plant materials, such as carbon , graphite, Teflon ® material with fillers , trying to find a suitable solution to the problem of wear and misalignment , all materials 2-3 months to be scrapped . Wherein the polytetrafluoroethylene material products due to wear so that the shaft wear, have a great leak , causing mechanical seal failure.
Workaround: polyimide carbon fiber composite materials instead of the original use of a filler PTFE bearings.
Results: polyimide carbon fiber composite material support bearings installed, has been successfully operating for more than 13 months , after using the first eight months , the central part of the agitator is removed temporarily use other equipment , then , the staff detected stirrer bearings, found on each side leakage rate is less than 0.005 per inch , then the average failure interval time increased by 300% to 400%.
(B ) the problem : the axis deviation caused by high vibration and shorten the life of the mechanical security seals, while generating the noise .
Workaround: polyimide carbon fiber composite material with stainless steel impeller mouth ring pump housing orifice ring ; using our materials throat bushings instead of the original graphite bushings.
Result: reduced vibration amplitude , thus extending the service life of the seal and bearing life , and enhance the free operation of the pump . Many pumps are in use as a filler in packing , packing main role is to prevent leaks, but also play a role in the bearing , stable axis . At present, many pumps have packing to mechanical seals, mechanical seals with the changes did not affect the bearing , while the axis deviation ( high vibration and associated impacts ) has become a problem .
Polyimide carbon fiber composite materials to improve pump , successfully resolved the customer's problem , the following main points:
A ) polyimide carbon fiber composite material is a non- metal wear , do not bite material . This allows the running clearance out ( API provides only half the interstitial metal material ), the smaller the gap can stabilize shaft bush , the smaller the gap can further limit the leakage orifice ring and leak rate.
2 ) Polyimide carbon fiber composite material is a high strength , high performance thermoplastic material .pull tight seal It is easy to injection molding, can absorb vibration and shock , while the metal is being replaced will cause vibration and shaft wear .
Parts : Equipped with a removable Teflon seal and bearing sleeve
