ZJA-R series is not only used to remove water, gas, particulate matters etc. from the transformer oil effectively and rapidly. But also can recover the waste oil color from maroon to limpid and transparent. ZJA-R series specialize in purifying insulating oil of high voltage and super high voltage transformer. Additionally, it is suitable for treating low viscosity lubrication oil.
Description
Tongrui ZJA-R series 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.
Edges of ZJA-R
◆ To remove free, soluble water, carbon, free and dissolved gases and particulate matters from insulating oil effectively and rapidly.
◆ Recover the oil color.
◆ Enhance the value of breakdown voltage greatly..
◆ Easy handling and maintenance.
◆ Online work and Inject oil into the transformers.
◆ Lower maintenance and replacement expenses.
◆ High efficiency and effectiveness.
◆ Small size, light weight, low noise
◆ Automatic reverse-washing system will extend the lifetime of filters and improve the performance of the filters.
◆ High performance security system including pressure protection device and automatic temperature controller makes purifier operate safely.
Structure:
◆Dehydration (Degas) System
1, The vacuum vessel can increase evaporation area efficiently. The heater, being placed on the vacuum vessel, becomes an evaporator. Thus the evaporation area of vacuum vessel is three times more than that of the general vacuum vessel.
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.
◆Filter Elements(particulate matter removal)
1, Stainless steel filters can remove 99.5% particles.The sizes of the filter elements 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, 20 micron etc.
◆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 temperature rang is 20C to 80C. The heater is controlled automatically. The heater will stop automatically when the oil temperature reaches 80 degree, and it will begin to heat when the temperature is lower than 40degree. 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.
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 or Siemens
2, Having several protection systems which will avoid oil ejection, overload and over voltage etc.
◆Infrared 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, When oil quantity is lower than the level of the float ball, then the oil pump will start-up automatically and pump oil into the vacuum vessel, when oil is up to the floating ball level, pump will stop automatically
◆Vacuum Pump
Rotary Vane Vacuum Pumps, is a basic equipment used for pumping air from sealed vessels to attain vacuum condition.
The vacuum pumps may be applied singly, or as the backing pump of the other kinds of pumps, such as booster pump, diffusion pump, molecular pump and titanium pump etc. it may be used for vacuum film-plationg, vacuum heat treatment, vacuum ca-sting and also air-extraction of electric tubes, bulbs and thermos flaks. The pump may also be equipped in medical institutions and laboratory.
