T6C series vane pump problems

The structure of the T6C series vane pumpis very compact, and the vane pump with a small gap is also very demanding on the hydraulic oil. No impurities, oil viscosity, oil cleanliness, and oil quality will affect the service life.

1. Check the direction of rotation of the vane pump; if the steering is wrong, the pump is not filled with oil. The work of the vane pump should be stopped immediately, and the motor and steering should be corrected according to the standard arrow direction of the T6C series vane pump, and the direction of rotation should be corrected;

2. Check whether the pump shaft is broken, the damaged rotor of the pump shaft cannot roll;

3. Check whether there is air leakage in the suction pipe. Due to factors such as tightening of the suction pipe joint, poor sealing of the suction pipe joint or oil leakage, and oil lumps in the filter, the necessary vacuum degree cannot be formed in the pump suction chamber, and the pressure and pressure of the pumped oil chamber The atmospheric pressure is equal, and the atmospheric pressure cannot make the oil tank enter the pump, and the poor sealing can be identified and countermeasures can be taken;

4. Check whether the viscosity of the oil is too high. If the viscosity of the oil is too high, the blades cannot slide out of the rotor groove due to the large sliding resistance, so as to replace the lower viscosity of the oil; Oil pipe, and fill the pump with oil and start;

5. Check whether the oil level is too low, if it is too low, add oil to the standard oil level in time;

6. Check whether the speed of the vane pump is too low, the centrifugal force cannot make the blades throw out of the rotor slot, and the sealing space cannot be changed. Usually, the speed of the Denison vane pump is less than 000, and the oil absorption is higher than 1800. Difficult to absorb oil;

7. Check whether the blades are stuck, the blades and dirt from the rotor grooves and burrs; the cooperation gap between the blades and the rotor grooves is too small; the hydraulic oil viscosity is too high due to the long shutdown time of the pump; the blades Due to corrosion and other factors, single or multiple blades are stuck in the rotor slot, cannot be thrown out, cannot build up pressure, and the oil seal space cannot exert pressure. , according to the specific situation;
