Failure Reasons Treatment
No oil •  pump shaft reversed 
•  pump oil does not rotate 
•  The suction hose or suction strainer is clogged.  
•  Suction hose airtightness is poor.  
•  The viscosity of the oil is too high.  
•  The mounting position is too high.  
•  Not enough revolutions.  
•  The variable pump has a displacement of 0 .  
•  Internal parts are worn or broken.
Correct the direction of rotation as required.  
Forgotten key on shaft or loose coupling.  
Remove the blockage.  
Check the pipe connection, tighten the screws, replace the gasket.

Replace the oil with one of appropriate viscosity, or preheat it with a heater.  
Try to keep the pump positioned no higher than the oil level.  
Run at more than the rated speed.  
Re-tune the variable mechanism.  
Replace or repair internal parts.
Insufficient traffic •  Internal parts wear out or break down.  
•  cavitation occurs.  
•  Inhale air.  
•  The variable mechanism is working poorly.  
•  The pressure distribution valve is not working properly.  
•  The viscosity of the oil is too low.
Replace or repair internal parts.  
Eliminate cavitation.  
Prevent air inhalation.  
Replace, repair, or disassemble for cleaning.  
Replace or disassemble for cleaning.  
Change the oil to one of appropriate viscosity and lower the oil temperature.
Abnormal fever •  Excessive internal leakage and excessive heat due to low volumetric efficiency.  
•  Sliding part burned.  
•  Bearing burnout
Repair internal parts.  
Repairing internal parts.  
Replace bearings.
Shaft seal oil leak •  The shaft seal is broken or there is a defect on the shaft.  
•  The same part of the leakage is too large, the pressure in the shaft sealing part increases.
•  Drain pipe clogged.  
•  External drain hose is too thin or too long.  
•  Excessive external leakage.
Replace the shaft seal or change the oil.  
Repairing internal parts.  
Clean the oil drain tube.  
Thicken or shorten the drain pipe.  
Repairing internal parts.  
Abnormal wear or short-term burn-out of internal parts •  Working oil contamination.  
•  Working fluids are mixed with water and air.  
•  Noisy.  
•  Improper working fluids.  
•  Operating conditions are too poor.
Change the working oil and add an oil filter.  
Eliminate the cause of mixing water and air.  
Eliminate the cause of increased noise.  
Replace the working fluid with a well lubricated fluid.  
Operate under proper conditions, especially when using water-repellent, flame-retardant working fluids.
