The serious reasons for the heating of the motor of the kitchen fume purifier in the restaurant are the local short circuit of the stator winding and the serious oil shortage of the oil-bearing and so on. It is necessary to clean and repair in time to restore the purification effect. If the key switch of the lampblack purifier doesn't work, the motor torque decreases and the speed slows down, it is necessary to replace the capacitor with the same specification. The short-circuit winding should be repaired or replaced. The kitchen fume purifier has poor lubricity. The thermal solution is to increase the amount of oil. If the bearing is damaged, please replace it. Each key switch can be locked. The mechanical performance is good, but the motor cannot be started. Check whether the male * * * connection of each switch is open and needs to be repaired. If one gear can't run the motor and the other gear is normal, check whether the contact is damaged or disconnected; Press the switch motor to run, but it cannot be locked after being released.
Check whether the conductive spring and conductive sheet of the switch are not in contact with the switch, or whether the switch spring sheet is disassembled and displaced. Adjust the spring leaf or replace the switch; Both gears are locked at the same time. If it is necessary to adjust and repair the interlocking spring, check whether the interlocking spring is displaced or deformed. The electrostatic fume purifier is improperly installed and the elevation angle is insufficient, so we need to reinstall it to ensure that the sucked oil can flow into the oil collecting box smoothly, and to prevent the oil discharging pipe from falling off or being damaged and the sealing strip of the oil collecting box from being broken.
