What are the common faults and solutions of semi-electric?

Semi-electric stacker is a new type of stacking machine with electric lift, light operation, environmental protection and high efficiency. It is mainly used in the movement and stacking of elevated goods and pallets. In workshops, stacks, logistics centers and other places, the semi-electric pallet stacker is used to carry out unitized pallet stacking, with low noise and high efficiency. It is very suitable for some cramped passages, floors, elevated stacks and other operating occasions. However, when even the best machinery will fail, what are the common faults and solutions of semi-electric stackers?

Common fault 1: The speed of the driving wheel of the stacker is significantly reduced or the driving motor is seriously overloaded

Cause of investigation: the battery voltage is too low or the contact resistance of the pile head is too large; the motor is commutated Carbon deposition between the plates causes short circuit between plates; improper adjustment of the motor brake causes the motor to run with braking; the drive head gearbox and bearings lack lubrication or the base is blocked; the motor armature is short-circuited.

Treatment: check the battery terminal voltage or wash the pile head when the stacker is loaded; clean the commutator; adjust the brake clearance; check and clean and refill the lubricating oil to remove the jamming phenomenon; replace it with a new one motor.

Common fault 2: The stacker is weak or unable to lift.

Examination reasons: excessive wear of the gear pump and pump electric pallet lift truck; improper high pressure of the relief valve in the reversing valve; Oil leakage in oil pressure pipeline; hydraulic oil temperature is too high; gantry carriage is stuck; oil pump motor speed is too low.

Treatment: replace the worn or gear pump; re-adjust the solution, check and repair; replace the unqualified hydraulic oil and check the cause of the oil temperature rise; check and adjust; check the motor and remove the obstruction.

Common fault 3: The semi-electric stacker gantry is difficult to tilt automatically or the movement is not smooth enough

Cause of investigation: excessive wear of the tilting cylinder wall and sealing ring; The valve stem spring in the reversing valve fails; the piston is stuck on the cylinder wall or the piston rod is bent; there is too much dirt in the tilting cylinder or the seal is too tight.

Treatment measures: replace the O-ring or oil cylinder; replace the qualified spring; replace the damaged parts; clean and adjust.

Common fault four: insufficient pressure of the oil pump or too slow speed

Examination reasons: damage to the sealing ring in the pump cover groove, excessive internal leakage; gear wear; oil pump motor speed reduction; pipeline There is a foreign body blockage.

Treatment:; replace the oil pump; check the commutator, remove the carbon deposits between the plates, adjust the position of the carbon brushes; check and clean.

Common fault five: abnormal electrical operation

Reason for investigation: the micro switch in the electrical box is damaged or the position is adjusted improperly; the main circuit fuse or the control electrical fuse is blown; the battery voltage is too high Low; contactor contacts are singed, or too much dirt causes poor contact; contacts do not move.

Treatment: replace the micro switch, readjust the position; replace the fuse of the same type; recharge; repair the contacts, adjust or replace the contactor; check whether the contactor coil is open or replace the contactor.

The common faults and solutions of semi-electric stackers are roughly the same, I hope to help you in your actual work.
