Analysiss and Solutions of Common Use Problems
Problems
1. Wrong oilport/rotation
The gear pump
2. Pump cannot rotate
does not
3. The viscosity is too high/low
deliver oil and
cannot build
4. Oil level is too low
enough
5. Internal structure wear out
pressure
6. Oil circuit leaking/not smooth
1. Filter stuck
Abnormal
2. Rotation speed is too high
vibration and
3. Air exists in the tube
noise
4. Oil impurities too much
1. Oil quality is too bad
2. Large oil sucking resistance
Abnormal heat
3. large circuit loss
4. High ambient temperature
5. High system pressure
1. Seal damaged
Oil leakage
2. Tube connector loosed

Exclusion Method
1. Use according to the rotation, check inlet/outlet tube.
2. Check whether there is foreign body stuck.
3. Change propriate oil, cold ambient please warm up.
4. Add the oil until the oil level passes the suction part.
5. Change/fix internal parts.
6. Check whether exists leakage or filter is stuck.
1. Check and clean the filter.
2. Lower the speed to adequate range.
3. Check whether the oil level is too low.
4. Clean and change the hydraulic oil.
1. Select the oil according to the requirement.
2. Reduce the resistance, enlarge the diameter.
3. Reduce the angle of oil turning
4. Add the heat resistance method.
5. Limit/reduce the working pressure
1. Change the seal.
2. Tighten the connector, please notice the torque.
