Vacuum Pressure Impregnating Equipment
This VPI vacuum impregnation equipment is specially applicable to heat insulation treatment of high voltage motors, traction motors, special motors, anti-explosion pumps, magnetic motors, transformer coils, and other high voltage products. It effectively reduces the fault rate, improves the insulation performance, and prolongs its service life of the finished product. We can design and make equipment according customers’ requirements.
First, put workpieces into the vacuum pressure tank, evacuate the moisture and air from workpieces under vacuum condition. Then fill impregnation liquid into vacuum tank by pressure difference or pump. In order to impregnate fully, add certain pressure to let impregnation liquid impregnate into gaps of workpiece.
- Easily evaporate moisture and air
- Residual water rate less than 10ppm, good insulation performance
- Good humidity resistance
- High dielectric property
- Impregnation can be reused to reduce environmental pollution
- Short impregnation time, good result
- Syncretizing different technologies of pressure vessel, vacuum, pressurization, refrigeration, heating and automation together
- PLC or industrial computer control, automatically measuring and controlling.
- Equipped with safety alarm and interlock protection devices
