Do you know the reasons why the motor temperature of kimchi food packaging machine is too high?

  Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? If the temperature rise is too high during operation, the service life will be shortened and fire will be caused. If the temperature rise of the motor is too high, it should be stopped immediately. The reasons for excessive temperature rise are as follows:

1. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Too much load. If the drive belt is too tight and the rotating shaft is not flexible, it may cause the packing machine to run under load for a long time. At this time should be appropriate with the mechanical maintenance personnel to loosen the belt to check the mechanical equipment, make the shaft flexible, and try to adjust the load, so that the motor to maintain the rated load state of operation.

2. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Poor working conditions. If the vacuum packaging machine mechanical and electrical motor is exposed to sunlight, the ambient temperature exceeds 40°C or operates in an environment with poor ventilation, the temperature rise of the motor will be too high. Can build simple shade shade or use blower, fan to blow air, to remove the motor itself air duct oil and dust, in order to change the cooling conditions.

Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? The supply voltage is too high or too low. The motor of packaging machinery can keep the rated capacity unchanged when operating within -5~+10 percent of the power supply voltage variation. If the power supply voltage exceeds 10 percent of the rated voltage, the magnetic flux density of the core will increase sharply, so that the iron loss will increase and the motor will overheat. The specific inspection method is to measure the bus voltage or the terminal voltage of the motor with an ac voltmeter. If the circuit voltage drop is too large, should replace the larger area of the wire and shorten the distance between the motor and the power supply.

3. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Power failure. If the power supply is out of phase, the single phase operation of the vacuum packaging electromechanical motor will cause the winding of the motor to heat up and burn up in a short time. Therefore, check the motor's fuses and switches first, and then use a multimeter to measure the front circuit.

4. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Cage rotor guide bar fracture, open welding or rotor guide bar cross section is too small, so that the loss increases and heat, rotor temperature can be tested after shutdown, find out the cause of fault and eliminate.

5. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Automatic vacuum packaging machine  mechanical and electrical motor starting frequently or too many positive and negative rotation times, should limit the starting times, the correct selection of overheating protection or replace the motor suitable for equipment requirements.

6. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? If the three-phase voltage is seriously unbalanced, it is necessary to check whether there is short circuit between the stator winding phases or turns and whether the stator winding is grounded.

7. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? If the vacuum packing mechanical and electrical motor bearings are not well lubricated or stuck, check whether the temperature of the bearing chamber is higher than that of other parts and check whether the grease is too little or dry.

8. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? The failure of the ventilation system is caused by the blocking of the wind road or the accumulation of too much ash on the heat sink.

9. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Friction between rotor and stator core causes continuous metal impact sound, which is easy to cause local temperature rise to be too high. Use heart check to find out the cause of the trouble.

10. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Take the motor of axial-flow fan, if the fan rotates in the opposite direction, it will also cause overheating.

11. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Transmission device failure (friction or jammed phenomenon), cause the motor excessive current heating, even make the motor stuck does not turn, resulting in a sharp rise in the temperature of the motor, winding is soon burned out.

12. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? Due to the change of winding parameters, the rewound motor will generate heat during trial operation. The three-phase no-load current of the motor can be measured. If it is larger than the rated value, the number of turns is insufficient, and the number of turns should be increased.

13. Do you know the reasons why the motor temperature of kimchi food packaging machine is too high? External wiring error; delta motor connected to Y connection. Although it can be started and run with load, the slightly larger load current may exceed the rated current and cause heat. If the ya connection motor mistakenly connected into delta connection, no load can exceed the rated current and unable to operate.
