Common faults and maintenance methods of electric forklift, check whether the tire screws are loose, whether the bearings are damaged, etc., the chain and chain pin shaft wear is too large, or the upper and lower staples of the fork and the fork beam are too large, The screws of the fasteners are loose, the guide wheels and rollers of the car body are seriously worn, and the open space is too large.
Check whether the friction between the rollers, guide rollers and the gantry is too large. Whether the cooperation space between the fork and the fork beam is too large, these factors will cause the electric forklift to have abnormal movement and static during use, and the forklift gear pump will fail, such as air entering the pump from the oil suction pipe or seal, and the resistance of the oil suction pipe is too high. large, and even partially blocked.
The precision of the gear pump is not high. The pump and the coupling are not coaxial. The solution is to add lubricating oil to the connection. If the abnormal noise decreases, it means leakage. Tighten the joint or directly replace the sealing ring; if there is no change, check the gear accuracy, carry out research and adjustment, and replace the gear if necessary. Finally, check the coaxiality of the pump and the coupling, pay attention to the difference between the working condition and the static condition, and adjust it according to the technical requirements.
