One, overview

For adapted power maintenance sector site maintenance various level pressure with oil equipment of need, we reference Japan Kato company of technology, strictly implementation national standards to DL/T521-93 vacuum filter oil machine using guide is for guide, design has volume small, proportion weight light, mobile convenient, noise low, continuous work time long, performance stable, operation convenient, features, is the power plant, power station, substation, electrical factory, industrial and mining enterprises filter transformer oil, through flat oil, hydraulic oil, oil liquid in the of water, The ideal equipment for gas and impurities.

Two main uses

1, the machine can be used in various types of oil-immersed transformers, oil-immersed current transformers and oil circuit breakers, oil filter and oil.

2, the machine can be used for hot oil circulation of these dry, especially for oil-immersed current transformers and oil circuit breakers thermal oil circulation drying is more effective.

3, the machine can be used to vacuum seal oil-filled equipment oil and oil and vacuum equipment.

4, this machine can also be used for minor modification of transformer oil regeneration purification, so that its performance achieves the qualifying standard.

Three main features

Compared with some of the similar domestic product has the following characteristics:

1, small volume, light weight, and is one-second of the weight of its kind.

2, improve and perfect the original oil-gas separator design. With vacuum inlet and install the tube rotating fuel injectors, reduces drag, faster swing speed, increase the separation effect.

3, bad oil regeneration purification function. Vacuum oil-filtering machine in the past, only a single remove impurities and moisture, native added silicone oil cleaning system and silicone oil with impurity filter for one, after a slight modification of transformer oil filter out impurities, after silicone oil adsorption and regeneration, to reach the qualifying standard of oil.

4, more than one machine. This is an important feature of this machine. Because of this machine to use in the field, and use the oil storage tank, thermal oil circulating between the machines and equipment, which makes oil filters, regeneration, hot oil cycle drying three functions at the same time, labor, and time is threefold.

Four working principles

Vacuum oil filter is under the water and oil boiling points of different design, which consists of vacuum heating pot, fine filter, filters, vacuum pumps, oil pumps and electrical cabinet. Vacuum pump will vacuum tank within of air taking formed vacuum, outside oil liquid in atmospheric pressure of role Xia, oil after entrance pipeline into early filter clear larger of particles, then into heating tank within, after heating to 40-75 ℃ of oil into vacuum tank within, oil in the of water rapid evaporation into steam and continuous was vacuum pump inhalation oil separation device within, separation device within of steam by cooling Hou restore into water Hou released. Heated in a vacuum tank drain pump into the filter through the oil filter impurities particles filtered out. Completed vacuum filters fast oil filter operation

1, three-phase four-wire zero line is to be connected and correction of vacuum pumps and gear pumps motor positive inversion.

2, close the inlet valve, the vacuum pump when vacuum above 0.04 open inlet valve, and then visually transparent observation of the largest tank when the oil comes in there is oil, open gear pumps, oil drain.

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

4, stop switching off electric heating, let the device continue to run for one minute to prevent heating tubes to burn out.

5, close the inlet valve, oil all in the largest tank emptying, stopping pumps and gear pumps, open the release valve at the top of, let the vacuum back to zero, and then closes the valve ends.
