Causes of pressure failure of aluminum alloy gear pump:
 
There are occasionally some small problems in the use of hydraulic gear pump HGP-2A-F12R. Today, ZF Hydraulic Equipment Manufacturing Co., Ltd. will discuss with you the small problems in the use of gear pump.
 
After the hydraulic gear pump HGP-2A-F2R works for a long time, the pressure of the hydraulic system will not go up or be lower than the normal pressure, which is mainly caused by the decrease of the vacuum degree of the hydraulic gear pump HGP-2A-F3R, the increase of the internal leakage, and the excessive clearance caused by the wear of the internal components of the hydraulic gear pump HGP-2A-F4R.
 
Here are some solutions:
 
1. The shaft sleeve of aluminum alloy hydraulic gear pump HGP-2A-F6R is seriously worn. Replace the shaft sleeve with a new one.
 
2. The thrust plate (located on both sides of the gear) of aluminum alloy hydraulic gear pump HGP-2A-F8R is seriously worn. It is recommended to replace the thrust plate.
 
3. The gear end face of aluminum alloy hydraulic gear pump HGP-2A-F9R is seriously worn. It is recommended to replace the steel gear.
 
4. The gear outer circle of aluminum alloy hydraulic gear pump HGP-2A-F11R is seriously worn. Solution: replace the gear with a new one.
