Automatic Stator Varnish Dipping Machine Motor Impregnation Insulation WIND-ZCJ



Application:

The continuous immersed machine is fully automated, with cycle baking, high production efficiency, good

ventilation, and a greatly improved work environment in the workshop. Therefore, it is widely used in

insulation treatment of small-sized motor coils such as pump,compressor,unversal motor stator and so on.

This type of automatic drip leaching machine is generally used to manually take and place the workpiece,

undergo preheating, dipping, dripping, gelling, and curing processes, and is completed by a chain drive at

a time. The process flow is as follows:

Clean the frame → put the stator → pre-baking → cooling → impregnation →drain → cure →

unload the stator


1. Clean up the frame

Clean the paint on the frame and other impurities, and apply anti-sticking measures to the frame, such as

brush grease.


2. Load on Stator

There should be no dust or other debris on the stator. It must be removed before dipping. The stator is

placed neatly in the frame according to a certain distance. Generally, the stator should be placed

vertically in the frame. Some lead wires have problems such as hardening after drying and poor

conductivity. Therefore, the lead wires are generally bundled and then lifted up to avoid impregnation

before dipping.


3. Preheat

Generally, the preheating section temperature is set to 110-150° C. After the stator undergoes preheating

for 10-30 minutes, the surface temperature reaches about 90 degrees, and the steam in the core and the

coil can be removed. On the other hand, the insulating paint after preheating can be used. Quickly

penetrates into the coil and iron core. From the profile of the continuous immersing machine, it can be

seen that the preheating section is in fact connected to the upper curing section. Therefore, when a

water-soluble insulating paint is used, although the water-soluble insulating paint may not be pre-baked,

the heater of the preheating section cannot be turned off and the temperature setting should be

consistent with the curing section for easy penetration and efficient use of the curing time.


4. Cooling

After the stator passes out of the preheating section, the temperature is not uniform, and the local

temperature is too high. If the high-temperature workpiece directly enters the oil-soluble insulating paint,

the solvent will evaporate rapidly and cause a safety accident. In addition, when the insulation paint is in a

high temperature state for a long time, the probation period is drastically reduced, and an increase in

viscosity or even an overall gel is liable to occur and the pipe is clogged. Therefore, it is necessary to go

through a brief cooling to reduce the stator temperature to about 70 degrees.


5. Dipping

The sloping frame is completely immersed in the lacquer. The immersion lacquer time is generally

controlled between 30-80 s. It is adjusted according to the size and structure of the stator. The flow rate of

the dipping paint should be adjusted to ensure that the dipping tank is full of paint.


6. Solidification

After the lacquer work is completed, the workpiece enters the drying tunnel with the driving device to

complete the curing process. Depending on the size of the workpiece, it usually takes 1-3 hours.
