FAQ:

• Solution:
Clean the oil filter, add oil to the normal liquid level, and check the sealing of the pipeline.
Replace worn parts (such as plungers, oil distribution plates) or grind mating surfaces.
Adjust the variable piston to increase the inclination angle of the inclined plate.
2. How to adjust if there is still traffic output at the median level?
Reason: Deviation, looseness, or wear of the control mechanism (such as wear of the inclined plate ear shaft).
Solution: Reset the controller, tighten or replace damaged parts, and check the angle holding force.
How to troubleshoot the high vibration and noise during pump operation?
• Mechanical reasons:
The pump and motor shaft are not concentric, the coupling is damaged, or the bolts are loose.
Wear of bearings or variable head bearings (dry friction or impurities in the oil during start-up).
