The lifting platform is used more and more widely. No matter it is architecture, civil engineering or people's daily life, it is inseparable from the lifting platform. When the lifting platform is used, it will encounter some faults. Among them, the insufficient output flow of the lifting platform pump is a common fault. What are the reasons for the insufficient output flow of the lifting platform pump? Elevator manufacturer takes you to learn:
Analyze why the oil output of the lifting platform pump is insufficient
1. If the pump does not discharge oil or the output flow is not enough, first check whether the steering of the pump is wrong and whether the speed is too low. The steering of the pump can be changed by changing the steering of the motor. If the speed is too low, the motor with high speed needs to be replaced or the speed increaser needs to be added.
2. The liquid level in the oil tank is too low. Replenish the oil or insert the oil inlet pipe downward.
3. The oil temperature of the aerial work platform is too high, which increases the internal leakage of the pump. Air cooling can be adopted or a cooler can be added in the oil tank.
4. The air inlet pipe leaks. The noise and insufficient flow of the pump are the manifestations of this failure. The air leakage point needs to be found and repaired *.
5. The oil inlet pipe is blocked, the oil filter may be blocked or there is sediment in the pipe. Clean or replace the coarse filter swab, and check the oil contamination if necessary.
6. Impurities and iron filings in hydraulic oil of aerial work platform enter the pump, causing serious wear of parts.
7. When the gear pump works under high pressure, the deflection of the gear shaft becomes larger, resulting in eccentric wear. When the pump works under normal pressure, the leakage increases by one. For troubleshooting, it is necessary to investigate the causes of pressure rise, such as whether the pressure valve acts poorly, so as to take measures.
8. When the temperature of the hydraulic oil of the aerial work platform is very high, the viscosity of the oil will be greatly reduced, the internal leakage will be large, and the output will be reduced. It is necessary to understand the operation and service conditions of the host, investigate the causes of oil temperature rise and take measures.
