Description

Oil Purifier Type Centrifugal Vacuum Oil Purifier

Usage:

This machine mainly used to recycle unqualified new oil, imported oil and super HV transformer oil, particularly applied in large scale 110KV transport voltage device and the national transformer substations.

Features:

1. Add Roots Pump supercharge system and secondary high vacuum separation dehydration and degasification system on the basis of high efficiency vacuum purifier, which enable the vacuum limit reaching ≤3Pa.

2. Being able to eliminate water, gas and impurities etc. harmful contaminants quickly and effectively under high vacuum and high speed operation status, could enhance the breakdown voltage up to 75KV.

3. Being able to remove little tiny water and various gases from oil, and ensure that there is no acetylene in oil.

4. This machine can inject insulation oil into transformers, and then make dryness disposal.

5. The advanced infrared liquid control automatically system, interlocking control for pressure protection and power heating system ensure that long-term safe and reliable operation.

6. Have the function of electrification online operation.

Superiority:

Compared with single-stage vacuum oil purifier, this machine is more quickly and more completely in dehydration, degasification and trash extraction; it makes the oil limited voltage- withstand value much higher. This machine has two purposes, which one as purification equipment; another can be an independent vacuum power supply. Besides, it can short the oil treating duration during installation and maintenance of transformer.

Edges of ZJA

1.To remove free, soluble water, carbon, free and dissolved gases and particulate matters, dust from insulating oil effectively and rapidly.

2.With Vacuum pump and Roots pump.

3.Enhance the value of breakdown voltage greatly.

4.Easy handling and maintenance.

5.Inject oil into the transformers.

6.Lower maintenance and replacement expenses.

7.Automatic reverse-washing system will extend the lifetime of filters and improve the performance of the filters.

8.High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely.

9.Utilizes coacervation technology, coalescing technology, separating technology and refined purification technology. To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.

 Different Angles for Oil processing machine

Structure 

Dehydration (Degas) System 

1, The vacuum chamber has flash tower, which can evaporate the water efficiently. Also it has the spraying nozzle with degassing elements design. The heater, being placed on the vacuum vessel, becomes an evaporator. Thus the flash tower of vacuum vessel is three times more than that of the general vacuum vessel. This innovation can dehydrate and degas effectively and efficiently.

2, The optimal structure of the dehydration (degas) system enlarges the surface area of oil exposed to the vacuum system and extends the flowing distance of the oil in the vacuum system. Thus there has sufficient time to remove the moisture and gas from the oil by vaporization.

Filtering System (particulate matter removal)

1, The filtering materials with variable apertures are made of specialized glass fiber. The sizes of the filtering fiber and aperture dwindle gradually in the different filtering stages. The impurities with different particulate sizes are filtered step by step. The capability of removing particulate matters and impurities is improved greatly by this method.

2, The filtering system has stable and prefect filtering fineness. The filtering fineness has several grades, including 1, 2, 3, 5, 6, 10 Micron etc. Oil β>=1000 after filter.

3, The filtering system is equipped with reverse rinse and filth device. It improves the effectiveness of filtering and extends the lifetime of filter awfully.

Oil heating System

1, The unique heater structure heats the oil uniformly.

2, Oil Heater System assures less then 1.0 w/cm2. During the heating process, the deterioration of the oil caused by overheating is avoided.

3, The oil temperature can be adjusted between 20C to 80C. The heater is controlled manually or automatically. The heater will stop automatically when the oil temperature reaches a certain degree.

4, Being installed with safety protection devices, the heating system is secure and reliable. The heater will stop operation automatically when the oil volume of inlet is too low to avoid the damages of the heater. 

Electrical Apparatus Controlling System

1, The main components of the electrical apparatus made by Schneider, Siemens and so on ensure the safety of the controlling system.

2, Having several protection systems which will avoid oil ejection, overload and over voltage etc. 

Oil-level Controlling System 

1, The oil-level floating ball or infrared liquid level automatic controller system are installed in the vacuum vessel to control the oil level so as to avoid the oil being suctioned into vacuum pump in the operation.

2, The new innovation of eliminating froth can avoid the oil being suctioned into vacuum pump. 

  Vacuum Pump

 Rotary Vane Vacuum Pumps, is a basic equipment used for pumping air from sealed vessels to attain vacuum condition.

Roots Pump

Roots pumps can be used as boosters combined with backing pump. Of a rotary vane vacuum pump,or a liquid ring vacuum pump.
