Five common faults and solutions of electric forklift motors

1. Failure to start may be caused by blown fuse, blocked control circuit, severe short circuit or open circuit in motor winding, short circuit between commutator segments, poor contact of brushes, heavy load or mechanical damage such as bearings. 2. The speed is abnormal, which may be caused by short circuit or open circuit of the winding, incorrect position of the brush and overload, damage to the bearing, low power supply voltage, etc. 3. The sparks of the brush may be caused by poor contact of the forklift brush, uneven surface of the commutator, incorrect position of the brush, dirty surface, short circuit of the commutator or short circuit of the motor winding. 4. High temperature is generated, which may be caused by overload, forklift bearings and oil seals are too tight, damaged or poorly lubricated, shaft core is not correct, armature and magnetic pole phase friction, winding short circuit, brush pressure is too large, incorrect position, poor rectification, etc. Causes. 5.

What is the cause of the volume water in the battery box of the electric pallet truck?
Generally, the water level of the battery is 10~15mm on the electrode plate. Most people think that it’s enough to fill up. In fact, it’s not like that. After filling up, nothing will happen, but it will be troublesome when charging. The battery will generate chemical aspects, heat, expansion, and bubbles. Make an analogy. It's like pouring water out of boiling water. Therefore, there will be a lot of water in the battery box, and this water contains a certain amount of sulfuric acid, which will corrode the box afterwards. If this model has wiring or pipelines at the bottom of the car body, these parts will be damaged and the car will be broken. Slightly.
