Gear pump start specific steps

Gear pump start specific steps have the following several aspects: 1, with the hand rotation coupling, should feel light, uniform force. 2. Check whether the rotation direction of the pump is correct. It should be in accordance with the direction indicated by the label on the pump body

 

Gear pump start specific steps have the following aspects:

 

1, hand rotation gear pump coupling, should feel light, uniform force.

 

2, check whether the rotation direction of the pump is correct, should be in accordance with the direction indicated by the label on the pump body, if there is no special requirements, the general gear pump station at the motor end, are left in and right out.

 

3. Check whether there is an unloading loop in the hydraulic system to prevent starting or stopping at full load.

 

4. Check whether the valves in the system are within the allowable pressure range set.

 

5. Fill the oil outlet with medium to avoid internal parts damage caused by dry grinding when the pump is started.

 

6, not less than 2 seconds of empty load operation, check whether the sound of the pump is normal and the direction of the flow is correct.

 

7. Adjust the pressure of the overflow valve to 1.0mpa and rotate for about 10 seconds to check whether the system's actions, external leakage, noise and temperature rise are normal.

 

8. Adjust the pressure of the overflow valve to the protection pressure operating range of the hydraulic system.

 

9. Inching the motor to see whether the rotation and sound of the pump are normal.
