Why does the hydraulic cargo lift fail to lift?
The demand for hydraulic cargo lifts is increasing, but in the process of use, there will be a phenomenon of weak lifting, or the phenomenon that the hydraulic lift cannot be lifted up. In this situation, it is necessary to check in time to find the cause, then what is the reason? Caused by the phenomenon of inability to lift?
1. The gear pump of the hydraulic cargo lift is damaged, which will make the pumped oil without pressure, so that it will be weak in lifting and lowering. We can change this phenomenon by replacing the gear pump.
2. The support valve or electromagnetic reversing valve of the hydraulic cargo lift fails to act. A. The input voltage of the electromagnetic coil is less than 240V. B. The electromagnetic coil is burned out C, the valve core is stuck, the solution is to repair or replace it.
3. For overload, each hydraulic lift has its own rated capacity. If it is overloaded, it will cause weakness or inability to lift. Reducing the load to make it within the load capacity can solve this problem. .
4. If the manual one-way valve is stuck, the return fails, or there is a serious oil leakage, by unscrewing the oil pump valve port bolt, repair, clean, replace the clean hydraulic oil, and replace the oil pump sealing ring.
5. The filter of the hydraulic cargo lift is blocked, the solution is to replace or clean it.
6. If there is insufficient hydraulic oil or the oil return valve is not closed, it will also cause the hydraulic elevator to be weak or unable to rise, so as long as it is replaced or cleaned, and the oil return valve is tightened, it can be solved this problem.
In the process of using the hydraulic cargo lift, if it is used improperly or not paying attention to some details, there will be some failures, so it is very important to carry out frequent maintenance and maintenance work, which can improve the stability and performance, and thus be more secure.
