There are many structural types of evaporator motors, no matter which type, in the design and manufacture, the refrigerant vapor must leave the heat transfer surface quickly and maintain a reasonable liquid level, so as to make full use of the heat transfer surface effectively.

　　A small amount of steam generated when the refrigerant liquid of the evaporator motor is throttled can be separated from the vapor and the liquid through the vapor-liquid separation equipment, and only the liquid separated from the vapor is sent to the evaporator to absorb heat, so as to improve the heat transfer of the evaporator. Effect.

　　In the process of using the second-hand evaporator motor, there are often some small problems. Some problems are not serious and will not affect the normal operation of the equipment, but some problems we have to pay attention to in actual operation. For second-hand evaporator motors, the problem of motor heating can be big or small. Of course, we still need to understand the reasons for the heat of second-hand evaporator motors.

　　The custom evaporator motor factory believes that the first reason may be due to existing problems such as overload, overload, cooling fan, etc., or it may be heat caused by mechanical friction, but the main problem is whether the bearing can work normally.

　　The customized evaporator motor factory found that the inferior bearings are prone to bearing heating or even failure. The production technology and production capacity of second-hand evaporator motors are very demanding. The motor shaft and motor stator are not assembled in the motor factory. Due to lack of technical guidance, It is easy to cause the concentricity of the main shaft to be inclined, which constitutes the phenomenon of bearing heating.
