vacuum pressure impregnation equipment introduction

1. vacuum pressure impregnation equipment application scale 


Vacuum pressure impregnation equipment is mainly used in the insulation treatment of electrical products. Such as high-voltage motor, traction motor, wind turbine, hydraulic generator, explosion-proof motor, coal mine special transformer, H-class insulation dry-type transformer, power capacitor, cable insulation data impregnation, etc. After vacuum pressure impregnation, the motor or transformer coil and other products can be dehydrated and degassed in the vacuum stage, so as to reduce the influence of impurities such as water and gas on the insulation; in the pressure impregnation stage, the insulating paint can penetrate into the interior of the insulation structure under the pressure, strengthen all the insulation, and then improve the insulation grade and the electrical performance of the product.


Vacuum pressure impregnation equipment is also used in the data profession to process data modification and improve organizational structure, so as to achieve the purpose of improving data performance. Such as graphite products, engine shell and other precision castings, firebrick, wood, etc. After vacuum pressure impregnation, the compactness of graphite is increased, the strength and resistance characteristics are increased; in car engine castings and high-pressure valves, the phenomenon of micro leakage can be treated by vacuum pressure impregnation, which can improve the product qualification rate and eliminate the leakage of the workpiece itself. Different impregnants (such as asphalt, preservative, etc.) can change the properties of the base material to achieve different effects.

2.vacuum pressure impregnation equipment advantages 


Under the process conditions, degassing and dehydration are easy; the residual water rate (below 10ppm) has good insulation performance, good moisture resistance performance, excellent dielectric property; the impregnating agent can be reused to reduce environmental pollution; the time required for impregnating products is short, and the effect is good, which greatly improves the productivity.


3. vacuum pressure impregnation equipment features


It is based on the advanced technology of pressure vessel, vacuum, pressurization, refrigeration, heating and automatic control. PLC or computer can be used to complete the measurement and control of the full automation. Equipped with safety alarm and interlock protection device to ensure the safety of use.


4. vacuum pressure impregnation equipment working principle


Vacuum pressure impregnation is to put the workpiece into the vacuum pressure vessel, vacuumize to remove the trace moisture and gas in the workpiece, and then inject the impregnation solution into the vacuum tank through the pressure difference or delivery pump, and exert certain pressure to make the impregnation liquid immerse into the gap of the workpiece, so as to achieve the purpose of full immersion.
