Electric Trolley Malfunction And Maintenance Methods
Electric truck that is the role of handling the logistics of moving goods handling equipment. All electric locomotive operation using power control system, without human operation, high efficiency, flexible operation, handling speed, is a more time-saving and labor-saving tool. In the course of the process of failure we how to solve!
First, the tremor occurred during the ascension
1. Boost air inside the cylinder, can be carried out by lifting the load several times and exhaust solution,
2. Hydraulic system oil spills, maintenance and replacement of oil seals and hydraulic cylinders.
Second, since the decline of the load
1. There is oil leakage in the tubing or oil connections, which can be changed.
2. Electromagnetic, manual valve, one-way valve dirt stuck or seal wear, resulting in internal leakage.
Remedy: Clean the valve block to replace the seal.
Third, the lifting speed is too slow or not
1. The tank is short of oil, you need to add hydraulic oil or all the replacement.
2. The relief valve is under pressure and readjust.
3 excessive wear and tear of the pump, resulting in internal leakage, need to be replaced.
4. Electromagnetic, manual valve, check valve, safety valve wear or seal wear and tear aging, need to be updated.
5. Long-term high temperature hydraulic oil hydraulic oil deterioration, viscosity decline, resulting in leakage, replacement of hydraulic oil.
Four, can not move forward or backward
1. The battery is not enough to recharge.
2. Walking control micro switch loose, locking screw.
3. DC contactor failure, maintenance and replacement.
4. Electronic control board damage, repair and replacement.
5. Drive motor failure, check and repair.
Fives, the battery life is short and can not be charged
1. Insufficient battery solution, add distilled water or lead-acid water.
2. Battery aging, replace the new battery.
3. Bad electrical outlet, trimming the contact surface.
4 battery serious collapse, damage, replace the uniform battery.
