Batte Mechanical Zhengzhou Co.,Ltd.(Tel: +86 371 67991755 / 67992755 Web site: www.battemachinery.com) is a professional manufacturer of Melt pumps,Loss-in-weight Feeder,Screen changer. The main products are Melt pump,Feeder machine,Screen changer and gear pumps,metering pumps. Batte has accumulated abundant experience on the application technique of melt pumps since we manufacture pumps professionally. Recently according to the development trend of melt pumps application all over the world, especially in the field of precise plastic extrusion, we have done extensive research on the pump operation performance, practical function, equipment structure and control technology and achieved regular achievements.

　　Methods of enhancing the working efficiency of the gear pump

　　The development direction of high pressure gear pump is to improve the working pressure, reduce loss, improve the efficiency of volume, reduce the ripple, reduce noise.To produce the high pressure pump.Efforts to improve the work pressure, reduce the leakage is to take the gear radial and transverse backlash compensation, minimize gear radial unbalanced force.To improve the bearing capacity, such as the dynamic pressure bearing, at the same time improve abrasion resistance parts in order to increase the working life.On balance to reduce noise, improve the working, in addition to improve the manufacturing accuracy, also can take measures from the following aspects:

　　1, increase gear teeth or gear ratio (internal meshing gear pump high pressure).

　　2, the parallel structure, make the two staggered pulse peak.

　　3, adopting the new tooth form, such as helical teeth and herringbone gear, cycloid gear.
