In order to meet the needs of various high and low pressure oil-bearing equipment, we refer to the technology of Japan Kato Company and Germany Siemens Company, strictly implement the national standards and follow the guidance of the use of DL/T521-93-2002 high-precision oil purification machine. This product is designed with the characteristics of small size, light proportional weight, convenient movement, low noise, long continuous working time, stable performance, and convenient operation. It is an ideal equipment for filtering moisture, gases and impurities in oils such as power plants, power stations, substations, electrical manufacturers, and industrial and mining enterprises to filter transformer oil, turbine oil, engine oil below 40℃, hydraulic oil and other oils. 2. Main uses 1. This machine can be used for various oil-immersed transformers, oil-immersed current, voltage transformers and oil-liquid relays to perform on-site oil filtering and oil replenishment. 2. This machine can be used to perform on-site hot oil circulation drying of the above equipment, especially for hot oil circulation drying of oil-immersed current, voltage transformers and less oil circuit breakers. 3. This machine can be used to vacuum oil filling and replenish oil on the sealed oil-immersed equipment and vacuum the equipment. 4. This machine can also be used to regenerate and purify the slightly deteriorated transformer oil to make its performance meet the qualified oil standards. 3. Main features Compared with similar products in the world and China, this machine has the following characteristics; 1. It has oil-deficient heating function and protects the heating pipe. 2. Use accurate temperature control instruments to automatically monitor the effect of ultra-high temperature stop. 3. Small size and light weight, which is one-half of the weight of similar products. 4. Improve and perfect the design of oil and gas separation. Using vacuum oil injection, a tubular rotary fuel injector was installed, which reduced resistance, fast rotation speed, and increased the oil-gas separation effect. 5. According to the needs of the user, the filter media in the oil purifier part is made of a special filter element as a filter medium, and the special filter element is made of non-woven dense paper. When it is found that the filtration is slow, just peel off a layer of non-woven dense paper outside. 6. A machine is multi-energy, which is an important feature of this machine. Since this machine is used on site and uses the original oil-carrying equipment as an oil storage tank, the hot oil is circulated between the machine and the equipment, so that the three functions of oil filtering, regeneration, and hot oil circulation and drying can be carried out simultaneously, saving labor, saving time, and killing three goals at one time.
