The common faults of electric pallet truck are: the speed of the driving wheel is significantly reduced or the drive motor is heavily loaded, the lifting and hoisting is weak or cannot be lifted and hoisted, the gantry is fully automatic and difficult to tilt or the posture is insufficient and smooth, and the working pressure of the gasoline pump Not enough or the rate is too slow, the power circuit is not running abnormally, etc. How to solve this common failure?
The speed of the driving wheel is reduced, and the drive motor is heavily loaded: The main reason for the reduction of the driving wheel speed of the electric stacker or the serious load of the driving motor is because the battery voltage is too low or the loop resistance of the pile cap is very large. Cleaning the pile cap can reduce the resistance. If the battery voltage is low, it must be replaced with a new rechargeable battery; the short-circuit fault between the plates caused by carbon deposition between the rotors of the motor of the motor can also lead to such common faults; the reason for this common fault is also that the motor braking system is poorly adjusted, causing the motor to brake. System operation and the drive head reducer and its rolling bearings lack of lubrication or the base is stuck, and the motor synchronous motor is short-circuited. The ways to deal with this common failure are: clear the motor rotor, adjust the brake system clearance, check clean and re-grease, remove the deck and replace the motor.
Excessive damage to the gear oil pump and pump casing: excessive damage to the gear oil pump and pump casing of the electric stacker, poor high pressure of the speed control valve without the hydraulic reversing valve will cause the lifting and hoisting to be weak or impossible to lift and hoist, and must be dismantled. Change the gear oil pump, and the high pressure can be adjusted again. In addition, there are also oil leakage from the steam pressure pipeline, excessive water temperature of gear oil, stuck gantry carriage and low rated power of the motor, which also cause the hoisting and hoisting is weak or cannot be hoisted and hoisted. The solution is to check Repair the oil leakage area of the steam pressure pipeline, remove and replace the gear oil and check the reason for the rise of oil temperature, adjust the gantry carriage and check the common faults of the motor and remove them.
The gantry of the stacker is skewed and the gantry is unbalanced: the automatic gantry of the stacker is difficult to tilt or the posture is insufficient and smooth. The reasons are: the valve seat in the hydraulic reversing valve is invalid; More damage; excessive scaling in the skewed hydraulic cylinder or excessive clamping of the hydraulic seal; the piston rod is stuck on the cylinder wall or the hydraulic cylinder is bent. The solution is that if the spring is invalid, it should be replaced with a new one immediately; if the seal ring is seriously damaged, it should be replaced immediately; if the hydraulic cylinder is also seriously damaged, the hydraulic cylinder must be replaced; the stains in the hydraulic cylinder should be cleaned up. It can be adjusted for excessive clamping of hydraulic seals, and parts such as piston rods should be replaced immediately if they are damaged.
