Key Points Of Use Of Seals For Vane Pumps

1. In order to ensure the reliable oil absorption of the vane pump of the hydraulic seal, the rotor speed should not be too low or too high, and 600-1500r/min is suitable. If the rotation speed is too low, the blades cannot be pressed against the inner surface of the stator, so it cannot absorb oil; if the rotation speed is too high, it is easy to cause the phenomenon of "empty suction" of the pump, so that the pump cannot work normally.

   
   

2. The viscosity of the hydraulic oil used in the hydraulic sealing vane pump should be between 2.5-5. If the viscosity is too large, the oil absorption resistance will increase, and the flow rate of the pump will be heard; if the viscosity is too small, due to the influence of the gap, the vacuum degree is not enough, which will affect the oil absorption.

3. The vane pump of the hydraulic seal has poor working reliability against the dirt in the oil, and the vane will be stuck if the oil is not clean, so pay attention to the filtration of the oil and the cleaning of the environment.

4. Because the vane of the vane pump in the hydraulic seal has an installation inclination angle, the rotor is only allowed to rotate in one direction.
