Vacuum oil filter flow selection and characteristics
First of all, when selecting the oil filter, pay attention to the filter transformer oil voltage level. Generally, the single-stage oil filter is only used for normal pressure test on the oil and the transformer voltage is lower than 35KV. The two-stage high-efficiency vacuum oil filter is suitable for large-scale power transmission and voltage equipment above 35KV and the national main transformer power grid. It is especially suitable for the chromatographic test and harmful gas detection of oil products in the area above 500 meters, and the two-stage high-efficiency vacuum filter. The double-cycle heating of the double-vacuum pump of the oil machine is mainly to use the screw pump to effectively solve the secondary pollution of methane gas.
The two-stage high-efficiency vacuum oil filter is suitable for large-scale power transmission and voltage equipment above 35KV and the national main transformer power grid. It is especially suitable for areas with altitudes above 500 meters, 100L/hour for 35KV transformers, and best double-stage vacuum for 110KV above 100L. High efficiency oil filter.
1. The two-stage high-efficiency vacuum oil filter is higher than the national standard. The primary filter breakdown voltage can be increased by 35KV, which reduces the hazard of oil quality aging caused by multiple heating of the general oil filter.
2, high vacuum, large pumping speed, pumping speed power ≥ 333L / s, to meet the need for vacuuming the transformer body at the installation or maintenance site, and at the same time complete the degassing and dehydration treatment of the transformer oil.
3, nano-molecular material filtration and complex three-dimensional flashing, high-efficiency removal of moisture, gas and impurities in transformer oil, improve oil pressure strength and oil quality.
4, fully automatic control, man-machine separation operation.
5, using VK micro-gram technology, can effectively remove trace water such as dissolved water.
6. It can realize vacuum oil filling, vacuum drying and vacuum filtration of power transmission and transformation equipment above 110KV.
â—† Vacuum oil filter equipment appearance The vacuum degassing tank, electric heater, condenser support steel frame and other equipment quality should be intact and the connection is not loose. There are no welds, burrs and rust spots on the welded parts. The surface of the product is spray-coated and connected by stainless steel bolts. The surface should be bright and bright.
â—† Vacuum oil filter heating system
1) The heating surface heat load is less than 1.0W/cm. During the heating process, it will never be damaged by the cracking and aging of the oil.
2) The heating system is safe and reliable, with safety protection device to prevent the heating system from burning without oil. The heating system is interlocked with the vacuum system and the oil draining system to avoid damage to the equipment due to excessive oil temperature.
3) Adopt interval control to avoid frequent start of contactor with oil temperature reaching the set temperature value and maximize the service life of the appliance.
4) Optimized heating device design, effectively eliminate the generation of harmful gases in the oil filtering process, and form a safe and reliable heating system. The optimized piping design ensures no “dead oil zoneâ€, and the oil temperature can be 20~80. Any adjustment between °C, constant temperature heating. At the same time, depending on the climate, automatic and manual heating methods are available.
â—† Vacuum oil filter oil delivery system
1) Basic requirements, manual turning, no jamming phenomenon, when running, the shaft seal does not leak oil, and the technical indicators reach the national standard;
2) The oil pump adopts the unique processing method by means of precision processing to ensure that the oil pump has no leakage; even if the whole system is in the limit vacuum pump, the oil is still normal, ensuring stable performance of the whole machine and improving oil processing efficiency.
â—† Vacuum oil filter vacuum separation system The two-stage high-efficiency vacuum oil filter adopts vacuum negative pressure principle. The complex three-dimensional vacuum separator greatly increases the vacuum separation area. The oil mist passes through the film atomizer in the vacuum separator. The device reaches atomization, thinning, gasification process, oil molecules and water molecules are completely in the vacuum system, so that the water and gas in the oil can obtain sufficient vaporization separation time to fully remove moisture and gas.
â—† Condensing system The unique medium condensing system completely cools the water vapor separated from the oil to prevent water vapor from entering the vacuum pump, causing the vacuum pump oil to emulsify and spray, prolonging the service life of the vacuum pump;
â—† Vacuum oil filter system
1) Three-stage step-by-step encryption and filtration system is adopted. The primary filter and the secondary filter are made of stainless steel, which has high filtration efficiency and long service life. The filtration precision is 50 μm and 20 μm to filter out large impurities such as iron filings in the oil removal. It can be backwashed according to customer requirements, and can be automatically flushed without disassembling the filter, eliminating a lot of manual cleaning work.
2) The fine filter adopts polymerized variable pore size filter material. The filter material fiber and pore size are gradually reduced along the flow direction of the oil, and the impurities of different particle sizes are layered and filtered, which greatly improves the dirt holding capacity and filtration precision, and can filter 1 to 5 μm. Impurity, the cleanliness of the filtered oil reaches NSA level 6.
3) It is equipped with a pressure alarm protection device (measuring the pollution degree of the filter element), and the design protection pressure is 3 kg to ensure that the filter screen will not be damaged by overpressure, reducing the use cost and ensuring the safety of the filtration system.
â—† Coalescence separation and filtration system of polymer water material in coalescence water-breaking emulsification system, combined with American coalescence separation technology, realizes binary dehydration, can quickly and effectively emulsification and remove a large amount of free water in oil, without harming oil chemistry Physical and chemical properties. Compared with the traditional glass fiber cotton demulsification, it has the advantages of high dehydration efficiency, no knotting, and no secondary pollution to the oil.
â—† Vacuum oil filter control system
