What to do if electric forklift price lift hydraulic cylinder and tilt hydraulic

 

The hydraulic system is an important part of the electric forklift price. In the process of using the equipment, this part will inevitably have problems. Before understanding the examples, we should roughly know that the hydraulic system includes the working device hydraulic system and the steering hydraulic system. For forklift manufacturers in China, when checking for faults, the unreasonable factors in the design must be eliminated first, and then the factors that cause the down speed limit valve and pipeline blockage to be eliminated based on experience.

After the electric forklift price increases the engine speed, the lifting and tilting hydraulic cylinders will move slowly. This situation will aggravate as the engine speed increases, but the steering system can still work normally, and the system can be heard regularly.

Then check step by step to find out if there is any leakage in the lifting hydraulic cylinder. If there is an internal leakage lifting hydraulic cylinder, hydraulic oil will flow out of the bleed plug. Forklift manufacturers in china suggest that a metal rod should be closely attached to the safety valve on the electric forklift price multi-way valve, and listen carefully for overflow sound. This can prove that insufficient oil pressure is not caused by the slow movement of the lifting hydraulic cylinder and the tilting hydraulic cylinder. main reason. Touch the pump by hand and feel the frequency of the vibration. If it changes corresponding to the engine speed, we can easily hear the pump making a deep sound. In this way, we can preliminarily judge whether the pump is malfunctioning.

If the cause of the failure is analyzed from the perspective of insufficient flow, then the lack of oil supply of the pump is the main reason. According to the observations of forklift manufacturers in china and the time of using the equipment, we can confirm that the low pump speed in the electric forklift price is not the cause of the failure. Therefore, the failure factor may be concentrated in the pump's insufficient oil absorption.

Based on this judgment, when we disassemble the suction pipe of the pump in the electric forklift price for inspection, it is easy to find that there are many filter pieces accumulated near the suction port of the pump. After cleaning the filter, re-install a new oil filter to the electric forklift price, and then try to see if the equipment can return to normal operation.

The above is the solution to the slow movement of the lifting and tilting hydraulic cylinders in the electric forklift price.
