The Problem Of Excessive Temperature Of Magnetic Drive Pump
TIME：2024-06-03 Author：admin Views：
In the use of magnetic drive pump, we may experience heat in the pump, in fact, part refers to the bearing, part of the pump body , part of the motor . And motor as the source of motivation, we need to pay attention to the relevabt issues to deal with , the general motor voltage exceeds the rated voltage, motor winding wiring errors, motor phase operation will lead to motor heating, in the case of motor heating when the treatment is timely shut down the motor, and then in the cool down before overhauling.
The following measures can deal with the problem of excessive temperature of motor of the magnetic drive pump:
● Start the motor frequently, excessive temperature of the environment, poor ventilation can cause the excessive temperature of motor, reduce the number of times to start the motor and the temperature of environment, ensure the smooth ventilation eliminate dust and oil accumulation, and keep the fan in good operation can help to solve the similar problem.
● The excessive load of the motor is also the cause of overheating, reducing the load or replacing the high-power motor can solve the excessive temperature problem.
● When the bearing of the motor is damage seriously, there will be large friction and heat genertion, the solution is to check whether the bearing is loose, whether the stator and rotor are poorly matched.
● Cage rotor of the motor with broken bars or loose coil joints of the wire-wound rotor will lead to an increase in current, then temperature rise, the solution is to butt-weld the rotor or replace it.
● The stator winding of the motor is short-circuited or grounded between turns or phases, which will lead to an increase in current and temperature rise, the solution is to add insulation to the center or directly replace the winding.
● There is a mistake in the winding wiring of the motor, which makes the motor running under the rated load overheat phenomenon, the solution is to correct the wiring error of the winding wire.
● Contact problems with the motor's power switch and a broken fuse in one phase can cause phase loss operation, resulting in higher motor temperatures, the solution is to repair or replace damaged parts.
The reason of excessive temperature of magnetic drive pump body :
If the outlet valve is not opened for a long time after the magnetic drive pump is started, it will cause the pump body to heat up.Therefore, when the magnetic drive pump is iperating normally, the ourlet valve should be opened in time.The reason for the heat of the magnetic drive pump body may has been emptied, the inlet end of the pump has brought in air or the inlet pressure is too low. Once the pump is vacuumed, in the absence of the water output, the liquid in the magnetic drive pump will constantly circulating and stirring, generating heat.
