1. When the electric pallet truck
battery is charging, especially near the gasification stage, the electrical reaction is that the water in the battery liquid is electrolyzed. The overflow of hydrogen (H) and oxygen (O) gases reduces the battery liquid capacity and increases the concentration. 2. The above reaction will also occur when the battery is discharged, but it will be strong when it is not charged, but when the battery is continuously discharged with a large current, the above reaction will also lose water. 3. In the fierce electrochemical reaction, if the battery liquid level is too high, the discharged gas will splash and overflow with the battery liquid, and the battery liquid level will drop (the sulfuric acid H2SO4 in the battery liquid increases with the battery liquid Overflow and loss). If supplemented pure water is used to maintain the liquid level, the liquid level of the battery liquid will change (that is, the specific gravity of the battery liquid is insufficient). Since the battery fluid splashing and overflowing of each unit is different, the specific gravity of each unit cell is inconsistent after such water replenishment, forming a potential difference between each unit cell, thereby affecting the efficiency of the battery. Therefore, try to avoid this situation in battery use.
Five common faults and solutions for electric pallet truck motors
1. Can't start, it may be caused by blown fuse, blocked control circuit, severe short circuit or open circuit of 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. There is noise, mainly caused by the damage of the bearings in the electric pallet truck parts, the uneven surface of the commutator, and the vibration or friction of the electric brush.
