An electric forklift is a mechanical vehicle that is driven by electricity to lift and travel. Therefore, the importance of the circuit system to the forklift is self-evident. Once there is a problem with the circuit system, the entire electric forklift will be in trouble, seriously affecting normal work. Next, regardless of the price of the forklift, the electric forklift manufacturer will tell you how to repair the oil pump circuit and steering circuit of the electric forklift.
Let me talk about the maintenance of the oil pump circuit failure of the electric forklift first.
Since the oil pump circuit is not controlled by the governor control board, the contactor coil is directly controlled by the oil pump switch, so the resistance of the oil pump circuit will only appear in the external circuit. The oil pump circuit obstacle is mainly manifested by the oil pump motor not operating normally. When checking, first check whether the seat or handle switch is closed: whether the oil pump circuit insurance is blown out; whether the oil pump switch is in good contact or whether the contactor switch has short circuit, open circuit or mechanical damage Stuck and so on. Electric forklift manufacturers tell everyone that no matter how much the price of the forklift is, it is also necessary to check whether the two windings of the motor have short circuits, open circuits, and whether the brushes are in good contact.
Let's talk about how to repair the steering circuit of the electric forklift when it fails.
Since the steering circuit contact is controlled by the governor control board, the steering circuit fault can be divided into internal circuit fault and external circuit fault. When checking, check the external circuit first, and determine whether the internal circuit is faulty on the basis of troubleshooting the external circuit. When checking the fault of the steering circuit, first check whether the seat or handle switch is closed, and whether the steering insurance is burnt out; then check whether the contactor coil is short-circuited or open-circuited, whether the contactor contact can be closed or has mechanical stagnation; Whether there is a short circuit or open circuit in each winding, and whether the brush contact is good. The electric forklift manufacturer tells everyone that if the external circuits work normally, it is an internal failure of the control board, and the control board should be replaced.
The above is the method of overhauling the oil pump circuit and steering circuit of the electric forklift.
If there is a circuit failure, the forklift operator can troubleshoot and repair it in time according to the above methods. Regardless of the price of the forklift, it is difficult to encounter circuit failures. Electric forklift manufacturers suggest that if you cannot solve it by yourself, it is most appropriate to find professional maintenance personnel to deal with it.
