Troubleshooting of electric stacker (handling truck), common use failure of stacker

1. The speed of the driving wheel of the lithium pallet truck is significantly reduced or the driving electromechanical is overloaded.

Reason: the battery voltage is too low or the resistance of the pile head is too large; the carbon deposit between the electromechanical commutators causes the inter-chip Short circuit; improper adjustment of the electromechanical brake causes the electromechanical belt brake to operate; the drive head gearbox and bearings are short and smooth or the base is jammed; the electromechanical armature is short-circuited.

Solution: Introspect the battery when the stacker is loaded End voltage or clean the pile head; clear the commutator; adjust the brake gap; reflect on cleaning and refill the smooth oil to eliminate the jamming situation; replace the new electromechanical.

2. Unable to lift

Reasons: gear pump and pump lift are moderately worn; the overflow valve in the reversing valve is low-pressure improperly; the oil pressure pipeline is leaking; the hydraulic oil temperature is moderate; the gantry slide exists Blocking scene; the motor speed of the oil pump is too low.

Solution: change the worn or gear pump; re-adjust; introspect and repair; change the failed hydraulic oil and reflect on the cause of the lower oil temperature; reflect and adjust ; Introspect the electromechanics and eliminate the faults.

3. It is difficult to actively skew the mast of the stacker or the measures are not fluent

Reason: the skewed cylinder wall and the sealing ring are moderately worn; inside the reversing valve The stem spring is in effect; the piston is stuck on the cylinder wall or the piston rod is winding; excessive deposits in the skewed cylinder or the seal is too tight.

Solution: change the O-ring or cylinder; change the pass spring ; Replace the damaged parts; clean and adjust.

4. The oil pump pressure is excessive or the speed is too slow

Reason: the sealing ring in the pump cover groove is destroyed, and the internal leakage is excessive; the gear is worn; the oil pump is electromechanical The speed is reduced; there is a foreign body in the pipeline.

Treatment methods: change; change the oil pump; check the commutator, remove the carbon deposits between the sheets, adjust the position of the carbon brush; check clean.

5 , The electrical operation is not abnormal.

Reason: The micro switch in the electrical box is destroyed or the status is not properly adjusted; the main circuit fuse or the control electrical fuse is blown; the battery voltage is too low; the contact of the warhead is burned, or Too much dirt causes bad warfare; the contacts do not act.

Solution: change the micro switch to re-adjust the status; change the fuse of the same model; recharge; repair the contacts, mediate or change the warrior; Introspect whether there is a break in the coil of the warrior or change it.
