Vacuum oil filter is a product for on-site oil filtering and oil replenishment for various oil-immersed transformers, oil-immersed current and voltage transformers and high-voltage oil-less circuit breakers. Vacuum oil filter is also called vacuum high-efficiency oil filter, oil filter, vacuum oil purifier

Vacuum oil filter is a complete set of mechanical equipment used to filter water, mechanical impurities, emulsification, free carbon, etc. in industrial oil to restore the oil index to the usable range; it is a good tool to extend the oil change cycle and save the cost of the enterprise. Lifelt Filter Co., Ltd. is a high-tech product manufacturer specializing in research and development, design and manufacture, technical services and equipment sales of modern oil treatment (oil filter, vacuum oil filter).

Introduction to the working principle of vacuum oil filter:

The vacuum oil filter produced by Lifelt is designed according to the principle of different boiling points of water and oil. It is composed of a vacuum heating tank fine filter, a condenser, a primary filter, a water tank, a vacuum pump, an oil discharge pump and an electrical cabinet. The vacuum pump pumps out the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil enters the primary filter through the inlet pipe to remove larger particles, and then enters the heating tank. After heating, the oil at 40~75°C passes through Automatic oil drift valve, this valve is to automatically control the amount of oil entering and exiting the vacuum tank to balance. The heated oil is rapidly rotated by the spray wings to separate the oil into semi-mist, and the water in the oil evaporates rapidly into water vapor and is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then returned to the original form of water to be released. The oil in the vacuum heating tank is discharged into the fine filter by the oil discharge pump to filter out particulate impurities through oil filter paper or filter elements, thus completing the vacuum oil filter quickly. The whole process of removing impurities, water, and gas in the oil, so that the clean oil is discharged from the oil outlet.

The main purpose of the vacuum oil filter:

1. It can be used for on-site oil filtering and oil replenishment for various oil-immersed transformers, oil-immersed current and voltage transformers and high-voltage oil-less circuit breakers.

2. It can be used for on-site thermal oil circulation drying of the above-mentioned equipment, especially for the on-site thermal oil circulation drying of oil-immersed current, voltage transformer and high-voltage oil-less circuit breaker.

3. It can be used for on-site vacuum oil filling and replenishment of sealed oil-immersed equipment and equipment vacuuming.

4. It can also be used to regenerate and purify mildly deteriorated transformer oil, so that its performance can reach the standard of qualified oil.

5. It can also be used in power plants, power stations, power companies, power transformation industry, metallurgy, petrochemical, machinery, transportation, railway and other industries.

Features of vacuum oil filter:

It has the characteristics of small size, light weight, convenient movement, low noise, long continuous working time, stable performance and convenient operation. It is ideal for filtering transformer oil, turbine oil, engine oil below 40#, hydraulic oil and other oils such as moisture, gas and impurity particles in power plants, power stations, substations, electrical appliances manufacturers, oil refineries, petrochemical and other industrial and mining enterprises equipment.

1. Small size and light weight.

2. Using vacuum to feed oil, a tubular rotary injector is installed, which reduces resistance, speeds up rotation, and increases the effect of oil-gas separation.

3. The regeneration and purification function of deteriorated oil has been added, and the silica gel oil purifier system has been added, and the silica gel clean oil and impurity filtration have been integrated. After the impurities have been filtered out for mildly deteriorated transformer oil, it has been absorbed and regenerated by the silica gel oil purifier. Make it meet the qualified oil standard.

4. There are two kinds of filtering methods for the oil purifier: one is the traditional oil filtering method—filter paper as the filter medium; the other method is the special fine filter element that does not need filter paper as the oil filtering medium.

5. One machine with multiple functions. When used on site, the original oil-carrying equipment is used as an oil storage tank to circulate hot oil among the equipment, so that the three functions of oil filtering, regeneration, and hot oil circulation and drying can be performed simultaneously. Labor-saving, time-saving, indeed kill three birds with one stone.
