Customizable Vacuum Pressure Impregnation Equipment
for High Voltage Motors and Transformers Insulation
1.General Introduction
High vacuum pressurizing impregnating equipment is the key
equipment for insulation treatment of high voltage motors,
special anti-explosion motors, and transformers. The vacuum
impregnating treatment enhances the mechanical strength,
insulation, anti-moisture and anti-mold performance of the
windings.Installation, test-running and training are provided
on the buyer’s site. The foundation drawing is also provided.
Installation type: vertical.Technical documents to be provided:
qualification certificate, technical features paper, main pressurized
components material list, welding line radiographic examination
report, spare parts nondestructive examination report, pressure
vessel appearance and physical dimension test report, welding
test plate mechanics and curving performance examination report,
pressure test inspection report, inspection certificate of pressure
vessel product safety performance.Manufacture standards:Steel
Pressure Vessels GB150-1998;Welding Specification for Steel
Pressure Vessels JB/T4709-2000;Vacuum System Design Standard
JB/T7674-95.Sealing ring of the impregnating tank: air-filling type
sealing ring.Other documents: bought-in components documents
and electrical components list; manual, foundation drawings,
electrical diagram, process flow charts, etc.

3.Equipment Parameters of Vacuum Pressurizing Impregnating System
| Vacuum impregnation tank | 1 set |
| Specification | Φ3300×3500mm(Effective impregnation height) |
| Working pressure | 1.0 Mpa (adjustable) |
| Working limit vacuum degree | 100 Pa |
| Head Material | 16MnR |
| Tank body Material | Q345-R |
| Flange Material | 16MnR |
| Resin return method | resin return from the bottom. |
| Pressurizing medium | filtered dry air (air source provided by the customer) |
| Working temperature | -10℃～80 ℃ |
| Installation form | vertical |
| Load bearing | The tank is equipped with a load-bearing bracket. |
After the tank cover is opened, the impregnation tank is equipped with safety interlock mechanism. | |
The impregnating tank is equipped with over-pressure alarm, and pressure safety device. | |
Hydraulic opening and locking of tank cover: The opening, closing, loosening and tightening of the tank cover are hydraulically driven. Its return signal is connected to the non-contact switch. | |
The opening angle of the tank cover is when the vertex of the opened cover projects downward beyond the inner wall of the tank. After the tank cover is opened, it does not affect the lifting of the workpiece. | |
| Liquid level transmitter. | |
The tank cover is equipped with explosion-proof sight lights and observation windows. The color of the equipment is specified by the customer. | |
The impregnation tank is equipped with upper and lower teeth-misaligned flange. | |
| The tank is equipped with the silicone rubber sealing ring. | |
4.Equipment Parameters of Resign storage System
| Resin storage tank | 1 set |
| Specification | Φ3300×3500mm(Effective height) |
| Working vacuum | -0.095Pa |
| Head Material | Q235-B |
| Tank body Material | Q235-B |
| Flange Material | Q235-B |
| Mixing method | The motor and reducer drive the blade agitator. |
The multi-layer paddle mixing device has a speed range of 25-36rpm, and the agitator and the positioning device at the bottom of the tank are easy to install, and the mixing effect needs to be fully complete. | |
| Equipped with sight lights, observation windows, etc. | |
| Equipped with stirring function. | |
| Equipped with cooling function. | |
The outer wall of the resin storage tank is equipped with a 100mm cooling insulation layer, and the interior is filled with a cooling medium ethylene glycol aqueous solution (concentration 40%) for cooling the stored resin. Insulation cotton and stainless steel armor wrapped around the insulation layer. | |
Equipped with vacuum pressure gauge, safety device, magnetic flip level gauge, resin level alarm, resin level can be continuously displayed on the computer. When there is no resin in the tank, the resin delivery valve will automatically close to prevent backflow. | |
A temperature sensor is installed on the tank to measure and control the resin temperature | |
5.Equipment Parameters of Vacuum System
| Vacuum system | 1 set |
| Maximum pumping speed of vacuum unit | 600L/S |
H-150 slide valve pump, ZJ-300 Roots pump, secondary vacuum, Level 3 vacuum , ensuring vacuum degree is achieved. | |
A vacuum buffer tank is installed in front of the vacuum unit to prevent resin from hanging on the pump rotor, adsorb condensable gases from the extracted gas, and protect the normal operation of the vacuum pump. | |
Before the exhaust gas from the vacuum unit is discharged into the atmosphere, it must pass through the exhaust gas separation condenser, and the condensed liquid must be manually released. | |
| The vacuum valve adopts a high vacuum pneumatic valve. | |
| Intelligent digital reluctance vacuum gauge, absolute pressure transmitter. | |
| Electric contact vacuum gauge, electric contact pressure gauge. | |
| Cooling circulating water tank, water pump, valve, pipeline. | |
