Characteristics of Compound Gear Pump

A ) compound gear pump flow characteristics ;
2 ) Compound Gear Pump Optimization Method ;
3 ) radial force balance methods and measures .seal cable Compound gear pump flow characteristics of the parameters involved in the calculation more complicated calculation , must resort to computer-aided design methods to achieve.
( 6 ) helical gear pumps helical gear pump research study is currently the focus of attention of researchers in domestic issues , Ganxue Hui , Zhao Liang and so on helical gear pump flow characteristics , the leakage flow characteristics , flow pulsation characteristics a study of helical gear pump research has laid a theoretical foundation.
( 7 ) gear pump gear pump noise noise control technology is engaged by the flow pulsation and shock caused by the control flow pulsation and noise from the lower tooth profile to start asking the relative sliding velocity .
( 8 ) Method of a variable gear pump gear pump because the engagement of the gear pump flow characteristic adjustment has been a problem , only up to consider the structural solution , there is no effective solution.
( 9 ) means of high-pressure gear pump gear pump working pressure increase is a development direction of the gear pump , the pressure increase caused by the question :
( 1 ) bearing life is shortened, shortening the life of the pump :
( 2 ) pump leak intensifies, the volumetric efficiency decreases.
Produce these two issues fundamental reason lies in the role of the unbalanced gear radial hydraulic pressure ,padlock seal and the pressure is higher, the greater the radial hydraulic pressure .
( 10 ) gear pump life and its influencing factors . Meshing gear pump unbalanced radial force is affecting the life of the main factors gear pump . Hydrostatic bearings can be used , reducing the radial force methods to improve the life of the gear pump , while reducing the radial force of the most effective way is to use more complex gear pump gear .
