The elevator manufacturer introduced such a phenomenon: people sometimes lift due to improper use of the elevator. The following experts analyzed the cause of this situation in detail. The elevator manufacturer talked about the damage of the gear pump, there is no pressure oil, you can replace the gear pump It is to be realized that the one-way valve of the manual pump is stuck, and the oil return fault, solve the oil pump valve bolts, repair, clean, and replace the hydraulic oil.

The elevator manufacturer analyzes the serious oil leakage of the manual pump and the gear pump. The solution is to replace the seal of the oil pump, the filter is blocked, and the solution can be replaced or cleaned.

The hydraulic oil is insufficient, and the solution is full of hydraulic oil; the oil return valve does not close the solution and tighten the return valve.

The elevator manufacturer warned that if the operation of the support valve or electromagnetic reversing valve fails, the solenoid coil input voltage is lower than 220V, the solenoid coil is burned out, and the valve core is stuck.The solution is to repair or replace it.

Remind the elevator manufacturer that if the elevator is overloaded, once each elevator is overloaded, it will have its own rated load, and it will not be able to lift, and reducing the load within the load range can solve this problem.

If it is open circuit, check the button contactor, fuse, etc.
