CHONGQING NAKIN ELECTROMECHANICAL CO. LTD
|VACUUM INSULATING OIL PURIFIER SUPPIER|
Series ZY Single stage stages transformer oil purifier
Series ZY high efficiency vacuum insulating oil purifier, mainly for the power station, industrial and mining enterprises purifying the unqualified transformer oil, mutual inductor oil, switch oil and so on. Series ZY can remove water, trace water, gas, particles from oil quickly and effectively, improving oil dielectric strength. Also, this oil purifier can be used to power equipments to vacuum drying, and vacuum oiling.
1.Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
2. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
3. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
4. Double-infrared liquid level sensor, pressure protective system to ensure the machine operation easy and safely.
5. Adopts interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.
6. Working with BZ insulating oil regeneration device to decolor (remove acid, oxide, free carbon) and lower dielectric loss, making the treated oil more limpidity.
Series ZY is efficient and economical insulating oil purifier. Duplex-Stereo film evaporation technology, unique and advanced dewatering, degassing components, making working efficiency is 3-5 times than traditional oil purifier. Machine adopts interlocked protective system, double-infrared liquid level sensor and pressure protective system to make sure the machine work unattended, operation easy, safe and reliable.

Vacuum oil purifier technologies and parts
Dehydration (Degas) system
The Double-horizontal vacuum evaporation vessels can enlarge evaporation area efficiently. The heater, being places in the vacuum vessels, becomes an evaporator. Thus the evaporation areas of Double-horizontal vacuum vessels are three times more than of the common vacuum vessel. This innovation can dehydrate and degas effectively and separately. This optimal structure of the dehydration (degas) system enlarge 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.
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 is improved greatly by this method.
The filtering system has stable and perfect filter fineness. The filter fineness has several grades. Including 18.104.22.168.5.6.10. Micron etc.
The filtering system is equipped with reverse rinse and filth device. it improves the effectiveness filtering and extends the lifetime of filter awfully
Electrical apparatus controlling system
The main components of the electrical apparatus made by Siemens, Schneider company ensure the safety of the controlling system .having interlocked protective system, pressure protective device which will avoid overload, over voltage, blank pumping, blank heating, oil leak and electricity leak etc.
Oil heating system
The unique effective electric heater structure heats the oil uniformly
Oil heater system assures less than 1.0w/cm2.during the heating process, the deterioration of the oil cuased byoverheating is avoided.
The oil temperature can be adjusted between 0ºC to 100ºC.the heater is controlled manually or automatically .the heater will stop automatically when the oil temperature reaches a certain degree
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 much to avoid the damages of the heater
Oil-level controlling system
The oil-level floating ball and double-infrared liquid level automatic controller system are installed in the vacuum vessel to control the oil level so as to avoid the oil leaking in the operation.
The new innovation of eliminating forth can avoid the oil ejecting and gushing during the process.
High quality components
The main component parts of our products such as vavuum pump ,oil pump, motor and electric apparatus are from SIEMENS, ABB, SCHNEIDER, LEYBOLD and AMICO etc. They ensure our products high quality and reliability.
Structure and apparatus of oil purifier
Our products adopt ship-shape chasis-mount structure to ensure oil leak proof and protect the environment from pollution.
The whole equipment is characterized by small size.light weight and convenient to move around.various sizes and configurations (alloy shield) available
Available in mobile or stationary options
Automatic vacuum oil purifier or anti-explosion vacuum oil purifier is both available according to customers' need.
Cooler, medium condenser system
The system is composed of cooler .condenser, water receiver etc.
The vapor and other gas, which is evaporated from vacuum separator, first drop in temperature and are rid of moisture in condenser, then are condensed again in cooler which has retarded exchange media .the reductive condensed water are discharged by water receiver, the dry gas, which are condensed and rid of moisture twice, are discharged to air by vacuum pump so that it protects vacuum pump.
The plant is characterized by small size, light weight, rich color, and our company can produce trail car type and closed type (alloy shield) according to the customer's requirement.
In order to make sure that the stable of oil purifier plant which can work long time and extend the life of the machine, the oil purifier's main parts such as electric control parts, electric motor, vacuum pump, oil pump are imported from SIEMENS,LEYBOLD,ABB etc.
