Vacuum Pressure Impregnation Plant

     Vacuum Pressure Impregnation Plant

Vacuum Pressure Impregnation (VPI) is a process that uses vacuum and pressure to seal porous materials with varnish or resin. The process is used primarily for high-voltage motors and generators to fill gaps in materials to create a void free insulation in various devices.

The Vacuum Pressure Impregnation Process
AR Engineering specializes in vacuum pressure impregnation, which is more effective than traditional dip-and-bake methods and is better suited to high voltage motors and generators. Our basic vacuum pressure impregnation motor repair process comprises several steps.

Preheating
We place the equipment in an oven that heats the equipment and allows moisture to evaporate. This helps the resin better penetrate the material.

Vacuum Drying
We remove the equipment from the oven and place it into a vacuum chamber, which removes air and any remaining moisture.

Filling
We fill the chamber with resin, coating the part and filling in all the gaps and pores in the piece of equipment.

Wet Vacuuming
We reduce the vacuum levels and hold it for a set period of time.

Pressure/Soaking
We increase pressure within the chamber using dry air, nitrogen, or other gases. This allows for even deeper penetration of the resin.

Draining
We then vent the pressure, drain the chamber of excess resin, and remove the part.

Curing
Finally, the equipment is placed into an oven to cure the resin.

Trickle Varnishing Machine:

In today’s competitive world the electrical insulation materials and the processes are viewed with tremendous cost and quality consciousness. Varnishing of electrical machine winding forms a major part of the total cost of the electrical insulating materials. With the increasing costs of energy and solvents for use in varnishing, it has become a need of the hour to look into the change in the conventional impregnation methods such as Dip and bake varnishing or the Vacuum impregnation.

On this background Trickle impregnation technique was evolved to improve the varnishing quality coupled with reduced cost. This technique is now well accepted and used for impregnating stators/fields and armatures/rotors in all the advanced countries.

Advantages of Trickle Impregnation:

• Trickle impregnation process is especially characterized by its low energy cost due to a very short cycle time compared to Dip varnishing or the Vacuum impregnation.
• Compared to the Dip and bake varnishing method, which uses varnishes containing 50 to 55% solvents and the impregnation cycle of 8 hrs to 24 hrs.
• Trickle impregnation cycle times are substantially low to the tune of 20 min. to 40 min. 
• Hence it is quite evident that trickle impregnation process offers the most cost economical answer to the impregnation process.

Advantages for Users:

• Good voids filling
• Accurate resin quantity
• No drain loss
• No post cleaning
• Continuous cycles
• Small space requirement
• Short impregnation cycle
• Lower/0 environment pollution
