What is the Difference Between a Single-stage Vacuum Oil Purifier and a Double-stage Vacuum Oil Purifier?

When oil products such as transformer oil are aged or polluted, we often need to use an oil purifier to filter or purify them. We often hear that there are single-stage vacuum oil purifiers and double-stage vacuum oil purifiers. So what is the difference between these two vacuum oil purifiers? The following will introduce in detail.

What is a Single-stage Oil Purifier?

Single-stage vacuum oil purifier

Single-stage vacuum oil purifier is suitable for insulating oil treatment of small transformers, as well as purification treatment of transformer oil, transformer insulating oil, circuit breaker oil, etc. Suitable for transformers below 110kV, the equipment is easy to operate, and can quickly and efficiently filter moisture, gas, impurities, etc. in oil. It is mainly used in power plants, the power industry, etc.

What is a Double-stage Vacuum Oil Purifier?

The double-stage vacuum oil purifier is suitable for oil purification treatment and vacuum hot oil circulation drying during the installation and maintenance of various large transformer equipment. Especially suitable for transformers above 110kV. The equipment is easy to use and can be equipped with casters for easy movement.

What is the Difference Between a Single-stage Vacuum Oil Purifier and a Double-stage Vacuum Oil Purifier?

the Functions of Single-stage Vacuum Oil Purifiers and Double-stage Vacuum Oil Purifiers Are Different.

Functions of the Single-stage Vacuum Oil Purifier:

1. It can efficiently and quickly remove mechanical impurities, gas, water, etc. in the oil.

2. It can greatly improve the dielectric strength, flash point, kinematic viscosity, and emulsification resistance of deteriorated oil.

3. The quality of deteriorated oil can quickly reach the usable standard, approaching or even reaching the corresponding new oil standard.

Functions of Double-stage Vacuum Oil Purifier:

1. The function of the double-stage vacuum oil purifier is more perfect than that of the single-stage vacuum oil purifier. Its effect of removing mechanical impurities, gases, moisture is faster and more thorough,

2. Higher improvement of the ultimate dielectric strength and flash point of the oil.

3. It can avoid the problem of oil aging caused by repeated heating of ordinary single-stage vacuum oil purifiers.

4. In addition to ordinary oil filtering functions, it can also perform vacuum drying and oil filling operations. It is suitable for vacuum hot oil circulation drying of new oil, transformer oil, switch oil, and other insulating oils at the installation and maintenance sites of various large-scale transformer equipment.

5. It integrates demulsification, dehydration, and precision filtration. After treatment, all indicators of the oil can be restored to the usable standard, ensuring the normal operation of the unit and the normal operation of the system.

Choice of Single-stage Vacuum Oil Purifier and Double-stage Vacuum Oil Purifier.

1. In terms of efficiency:

  • If you have high requirements for removing moisture, gas, and increase the breakdown voltage of the oil, you can choose a double stage vacuum oil purifier.
  • If you only need to deal with small transformers, you can choose a single-stage vacuum oil purifier.

2. In terms of processing effect:

  • If you have high requirements for removing moisture, gas, and water-soluble acids and alkalis, you can choose a bipolar vacuum oil purifier.
  • Correspondingly, if the requirements are not so high, you can choose a single-stage vacuum oil purifier.

As general equipment for processing transformer oil in the market, the two-stage vacuum oil purifier machine has an uncomplicated equipment principle. However, the specific equipment varies greatly due to the different technical conditions of various manufacturers. The service life of the equipment, the test results of the filtered oil, etc., are all related to the design of many details, the choice of configuration, and are related to the manufacture of different manufacturers.
