I. Overview

In order to meet the needs of the electric maintenance department on site maintenance of all kinds of high and low pressure oil equipment, we refer to the Japanese company Kato's technology, strictly enforce the national standard to DL / T521- 93 vacuum oil purifier use guidelines as a guide, designed with small size, The proportion of light weight, easy to move, low noise, continuous working time is long, stable performance, easy operation and so on, is the power plant, power station, substation, electrical factory, industrial and mining enterprises filter transformer oil, turbine oil, hydraulic oil Ideal for moisture, gas and impurities in the oil.

Second, the main purpose

1, the machine can be used for all types of oil-immersed transformers, oil-immersed current, voltage transformers and less oil circuit breakers, the scene of oil and fuel.

2, the machine can be used for the above-mentioned equipment on-site hot oil circulation drying, especially for oil-immersed current, voltage transformers and less oil circuit breaker hot oil drying more effective.

3, the machine can be used for sealing oil immersion equipment on-site vacuum filling and fuel and equipment vacuum.

4, the machine can also be used for mild deterioration of the transformer oil regeneration purification, to achieve the performance of qualified oil standards.

Third, the main features

The machine and the current domestic comparison of some similar products have the following characteristics:

1, small size, light weight, is the weight of similar products one-half.

2, improve and perfect the design of crude oil and gas separator.Use vacuum into the oil, installed a tubular rotary injector, reducing the resistance to speed up the swing speed, an increase of oil and gas separation effect.

3, an increase of the regeneration of the metamorphic oil purification function. The previous vacuum oil purifier, just a single removal of impurities and water, the machine increased the silicone oil system, and silica gel oil and impurities filter together, for the light Degenerate transformer oil filter impurities, after the adsorption of silicone oil purifier regeneration, to meet the standards of qualified oil.

This machine is an important feature of the machine because the machine used in the field, and the use of the original oil equipment to do storage tanks, so that hot oil circulation between the machine and the equipment, so that the filter Oil, renewable, hot oil circulation dry three functions at the same time, the provincial workers, time-saving three times in one fell swoop.

Fourth, the working principle

The vacuum oil purifier is designed according to the difference in boiling point of water and oil. It consists of vacuum heating tank, fine filter, filter, vacuum pump, oil pump and electric cabinet. The vacuum pump draws out the air in the vacuum tank to form vacuum, Oil under the action of atmospheric pressure, the oil through the inlet pipe into the filter to remove the larger particles, and then into the heating tank, after heating to 40-75 ℃ oil into the vacuum tank, the water quickly evaporates into water The vapor is continuously sucked into the oil-water separator by the vacuum pump, and the water vapor in the separator is cooled and then reduced to water, and the oil in the vacuum heating tank is discharged into the filter by the oil pump to filter the particulate matter through the filter element. Vacuum filtration fast oil filter operating procedures

1, three-phase four-wire zero line to be connected, correct the vacuum pump and gear pump motor is reversing.

2, close the oil inlet valve, start the vacuum pump, when the vacuum reaches 0.04 or more to open the oil inlet valve, and then visualized the largest tank of the transparent look, when the oil comes inside when there is oil, open the gear pump,

3, oil out of balance after the opening of electric heating. (Note: normal operation.)

4, shut down before the turn off the electric heating, so that equipment to run for a minute to prevent the heating tube burned.

5, close the inlet valve, the largest tank of oil all emptying, stop the vacuum pump and gear pump, open the top of the release valve, so that the vacuum back to zero, and then close the release valve, the end of the work.
