Failure of double mouth cement packaging machine motor protection device after operation

After the motor protection device of the double-mouth cement packaging machine malfunctions, what should we do? This is a problem we are going to introduce to you. Let's take a look.

1. The failure of the double-mouthed cement packaging machine is because the dragged machine is dragged by human force to check for blockages. If it is stuck, if the crank is not moving, the coupling or transmission belt should be removed and re-rotated separately. Machinery and motor shafts, if the machinery is stuck, the equipment personnel should be notified for further inspection; if the motor disk is not moving, the bearing covers of the front and rear bearings should be opened to check whether the bearings and lubricants are normal. If the bearings are basically normal, the motor should be disassembled Check whether the stator and rotor are stuck.

2. Whether the control circuit of the motor works normally. The empty test means that only the control circuit has power, and the main circuit switching elements and the motor must not be powered. Check the operation status of each component. In general, the power of the control circuit should be connected to the main switch. At the gate, perform an empty test when the main switch is off. At the same time, check whether the circuit breaker or fuse of the control circuit is normal. If necessary, the motor load line should be temporarily disconnected from the cabinet, and then the power switch should be closed to bring power to the Test the control circuit, and use a multimeter to measure whether there is power at the disassembled place, and further judge whether the switch is badly ended or has no-close phenomenon.

3.Use a multimeter or test lamp to check whether the terminals of the motor terminal box are short-circuited to the ground (housing), and check whether the head and tail of each phase coil are connected. In general, the motor just stopped does not need to shake the meter for measurement.

4. Touch the motor case with a hand or a thermometer. If the temperature is too high and you are hot, you must disassemble the connection between the motor of the cement packaging machine and the machine, and further check the motor.
