Post-maintenance of rail lifts
Rail lifts typically operate at higher speeds than other lifting equipment at the time of purchase. However, since the operation method of the rail type elevator is different from that of other elevator equipments, the running speed of the rail type elevator is becoming slower and slower.
1. The lifting speed of the hydraulic rail type freight elevator is slowed down, and the relief valve is adjusted by itself. After the relief valve is adjusted, the lifting speed is not improved, but the rail-type lifting freight elevator has a fault stop operation.
2. After the equipment is purchased and used, the speed is slow due to improper use or aging, and the use of hydraulic rail type freight elevators for dirt. After the speed is slow, consider the factors of hydraulic oil flow. Factors affecting hydraulic oil flow are: hydraulic lines, hydraulic valves, hydraulic oil pumps, motor speed control devices, etc.
3. The relief valve is generally placed inside the pump station and has a regulating valve on one side. Its function is to prevent the hydraulic system from being over-stressed and to protect the hydraulic system. It is dangerous to simply set the relief valve. If the pressure in the cylinder or oil pipe is too large, it is likely that there will be serious blasting failure. The rail lift freight elevator customer stopped the fault because he adjusted the relief valve by himself.
