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.

We produce stator varnish machine in electricity power,diesel power
or gas, It has two types mechanism in
the varnish area:
1. Varnish tank goes up and down which is driven by the screw rod
2. Varnish tank fixed and the chain goes down and up
Situation 1 is suitable for stator with dipping time requirement,
suppose the varnish dippin time is 2
minutes and pitch time is 5 minutes, stator don't need to stay
inside the varnish tank for 5 minutes
In situation 2, the varnish tank don't move and don't need
transmission, no drive needed,
Stator varnish machine which mainly applied to stator winding
insulation treatmen composed of machine
body, water cooler chiller and varnish supply tank.
