Main Components List

4) vacuum system

a) The vacuum system is comprised of 2X-30 rotary vane pump,main valve, vacuum buffer,

vacuum meter, pipes, and valves.

Main Components

5) vacuum buffer:

The vacuum unit is equipped with a vacuum buffer at the air inlet. This buffer keeps

the solvents out of the vacuum unit, and prolongs the service life of the vacuum unit.

6) filtering buffer:

This paint goes through the filter pipe and stainless valves, and then come into the

impregnating tank. The filter removes impurities out of the paint, and improves the

impregnation effect.

7) cleaning system

The cleaning system connects the cleaning tank and the impregnating tank.

It cleans the impregnation tank, pipes, valves and flanges, and returns the

cleaning liquid to the cleaning tank for use next time.

8) paint supply and return system

a) The paint supply and return sytem works througth the pressure difference. The

level is monitorable at the time of paint supply and return.

b) It is comprised of specially designed filter, paint supply and return valve, pipes, etc.

c) When supplying the paint, the control valve has to be shut down when the paint

level meets the preset value.

FUNCTION: circulation of insulation paint between the impregnating tank and the

paint storage tank.

9) exhaust system

a) The system is comprised of air discharger and pipes.

FUNCTION: The system is used to remove the waste gas of the impregnating

tank and the vacuum pump.

Main Components

10) electrical control system

a) It is comprised of electrical control cabinet, temperature meter, contactor, transformer,

and voltage meter. The control system has a high stability.

Main Components

11)anti-explosion system

The equipment has safety interlock device.

12) hydraulic system

FUNCTION: The system opens or locks the tank lid of the impregnating tank.

Main Components

13) heating system

This system is used to dry the workpieces through 36kw electrical heating tubes.

It is comprised of a fan, heater, high pressure valves, and heat preservation material.
