FAQ:

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).
• Hydraulic reasons:
The oil inlet pipe is too thin, the oil filter is clogged, or the oil viscosity is too high.
• Solution:
Reinstall and replace worn parts.
Select appropriate oil to ensure smooth fuel tank design and piping.
What are the causes and solutions for overheating of the pump body?
• Reason:
Mechanical friction (such as improper clearance between moving parts) or liquid friction (high-pressure oil leakage converted into thermal energy).
Filter blockage leads to excessive back pressure in the return oil.
