1： Application characteristics of oil purifier
oil purifier or vacuum oil purifier is mainly used for purification and regeneration of turbine oil in power plants and power stations. Make the oil meet the operation standard. oil purifier features:
1. The oil purifier can simultaneously complete the functions of high content dehydration and deep dehydration, impurity removal, degumming, demulsification, acid removal, decolorization and oil exposure;
2. At the same time, it has the combined functions of molecular filtration, coagulation dehydration, box filtration, pressure filtration and vacuum deep drying;
3. The oil purifier adopts fuzzy control technology, which has reliable operation and long service life; It has the functions of pressure overload protection, automatic dry prevention, automatic foam elimination and automatic oil level control.
4. The oil purifier is equipped with its own cooling water tank and has its own cooling cycle;
5. The oil purifier can be purified online synchronously with the unit, and the separated water can be discharged online (without breaking the vacuum);
2、 Structure and working principle of vacuum oil purifier and centrifugal oil purifier
The vacuum oil purifier adopts the combined technologies of expansion, condensation, molecular adsorption, vacuum drying, mechanical filtration and fuzzy control, which can remove the water, impurities, soaps, acids, colloids and pigments in the turbine oil, so that the severely emulsified turbine oil can be demulsified, transparent and meet the qualified standard. It is suitable for on-line purification and treatment of turbine oil such as hydraulic, thermal power generation units and industrial steam turbine units The structure of oil purifier is mainly composed of coarse filter, heater, vacuum cylinder, atomizer, vacuum pump, oil drain pump, cooler, temperature controller, precision filter and electrical control.
The working principle of centrifugal oil purifier is simple and the working effect is remarkable. There is a rotor with double jet nozzle inside, which only needs the pressure generated by the oil to provide its driving force. After the equipment is turned on, the oil in the oil tank is sent to the rotor through the pump. After the oil fills the rotor, it is sprayed along the fuel injection nozzle at the lower part of the rotary table, and then the driving force is generated to make the rotor rotate at high speed. Its speed can reach 4000-6000r p. M or more, the generated force is more than 2000 times of gravity, and the impurities are directly driven to separate from the oil by the principle of centrifugal force. Hard and sharp abrasive metal substances, plus residual deposits that wear parts or deteriorate engine oil, even 1 μ M that size can also be taken out. The separated impurities are attached to the impurity collection cover in the rotor and only need to be cleaned regularly. In addition, since the specific gravity of water is larger than that of oil, under the action of centrifugal force, water is separated from oil and stored in the oil pan in the rotor, which only needs to be removed during cleaning. The filtered oil flows directly back to the oil tank through gravity.
In order to make the machine work for a long time, you need an oil purification system that can minimize the loss of lubricating oil and maintain high cleanliness, so that your maintenance cost can be reduced. Now you will have the best oil purification system in the world: a real centrifugal oil purifier.
Because the general I filter is cleaned by the filter element, their disadvantage is that small particles will easily pass through or be completely blocked by large impurities, causing damage to your U machine. The rotor in the centrifugal separator does not contain anything other than separating the impurities in the oil, which will never affect your oil and additives in the oil. The separation type cleaning action starts immediately from the start of the engine and will not stop in the middle. Even when the amount of filth treated by it is more than 5 times that of the general filter, it can still maintain the cleanliness in the oil and the additives of the oil can last for a long time.
