Causes the pressure of the hydraulic shade machine to be unstable
1. Inhale air from the suction inlet of the pump. Ensure that the connectors of the pump suction passages are tightly connected so that they do not leak. The suction inlet is submerged in a certain depth of oil.
2. The suction port is somewhat blocked. Check the suction port area is not satisfactory.
3, the inner rotor speed is too low. Check if there is looseness or slippage between the spindle-to-inner rotor power transmission connection.
4. The worm gear, worm gear or gear meshing condition is not good, and the time difference is good, resulting in the high speed and low speed of the inner rotor. It is not normal to check whether the worm, worm wheel or gear of the pump drive system, the inner rotor fastening screw or the positioning pin are loose, and the engagement of the worm wheel and the spindle worm is normal.
