How to do when the switch fails during the operation of the hydraulic elevator at high altitude
Hydraulic lift freight elevator is a kind of machine and equipment operating at high altitude, this equipment is a relatively common equipment in the industrial field. Hydraulic lift freight elevator in the work is generally dependent on the switch to operate, sometimes the hydraulic lift freight elevator switch will fail, do you know why the hydraulic lift freight elevator switch will fail?
There are several reasons.
1. When the hydraulic lift cargo elevator system rupture car stall down, can automatically cut off the oil circuit to stop falling.
Hydraulic lift emergency manual valve: when the power supply fails, can make the car emergency fall to the near floor position to open the door.
Manual pump: When the system fails, the manual pump can be manipulated to make high pressure oil to make the car rise to the nearest floor position.
2. Oil tank oil temperature protection: When the oil temperature in the oil tank reaches the standard setting value, the oil temperature protection device will signal and suspend the use of the elevator, and the elevator can be started only after the oil temperature drops. Guide rail elevator water line, goods warehouse, parking lot, wharf, construction, logistics and other high-altitude goods up and down transportation. Overflow valve: It can stop the system pressure from being too high during the upward movement, and stop the equipment from being in a condition to fall suddenly.
Solution to the failure of the switch during the aerial operation of the hydraulic elevator freight elevator.
1. Hydraulic lift freight elevator falling process is to use its own gravity to fall, directly press the down button to fall. Check whether the external power supply is normally connected, no power equipment is unable to rise.
2. Check whether the hydraulic lift cargo elevator electrical switch is connected or poor contact, if intact, you can exclude the problems of the electrical system. If you find the electrical problems can be repaired on it. Solenoid valve stuck will also appear the condition of button failure. If the problem of the solenoid valve, you can first press the top lever of the electromagnetic to make the lifting platform down, and then clean and replace the solenoid valve.
