How to provide the volume efficiency of gear pump HGP3A-F17R?
 
For how to provide the volume efficiency of HGP3A-F19R gear pump, first of all, we should know what the volume efficiency is, know ourselves and know each other, and win every battle. Hgp3a-f6r hydraulic gear pump has loss in the process of energy conversion, the input power is greater than the output power, and the power loss value is the difference between the two. The volume loss of HGP3A-F8R of gear pump is caused by the leakage of hydraulic oil. The gear of HGP3A-F23Rof gear pump inevitably produces friction when it rotates. If there is friction, there will be loss, which is called mechanical loss.
 
According to my more than 20 years of experience in the production of gear pump HGP3A-F25R, the measures to improve the volumetric efficiency are summarized as follows:
 
(1) Try to keep the high pressure gear pump HGP3A-F28R hydraulic oil temperature and viscosity in the appropriate range;
 
(2) Keep the end clearance of HGP3A-F30R of hydraulic gear pump, and the clearance between tooth top and tooth side within the specified range.
 
(3) Try to keep the seal such as HGP3A-F11R shaft seal of gear pump working normally.
 
(4) The pressure shall not exceed the rated pressure of gear pump HGP-3A-F6R
 
(5) Keep the input pressure of gear pump HGP-3A-F13R normal;
 
(6) The speed of HGP-3A-F28R gear pump shall be controlled within the rated speed range, generally about 1000-1500r / min, not too high, but not too high. It can't be too high or too low.
