Abstract
The invention relates to the technical field of insulation oil purifying, and especially relates to an insulation oil filtering machine. According to the insulation oil filtering machine, an oil inlet valve, a rough filtering device, a vacuum degassing tank, an oil pump, a fine filtering device, and an oil outlet valve are connected by using pipelines. A heater is connected on the vacuum degassing tank. An oil mist separation device is arranged between the vacuum degassing tank and the oil pump. An oil returning valve is arranged between the rough filtering device and the fine filtering device. The filtering machine provided by the invention has the advantages of simple structure and convenient application. With the machine, insulation oil impurity can be sufficiently filtered, insulation oil purity and performance are improved, insulation oil service life is prolonged, and oil-consuming device wear degree is reduced.
Description
Technical field
The present invention relates to the insulating oil purifying device technical field, especially a kind of insulating oil filter.
Background technology
At each industrial circle, especially various electrical equipment use insulating oil in a large number in power industry, these insulating oils in use unavoidably will be sneaked into some moisture and all kinds of impurity, insulating oil there is pollution, and aged deterioration in various degree also can occur in insulating oil itself, affect the serviceability of insulating oil, increase the extent of deterioration of the oil-using units of knowing clearly.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of filtration insulating oil impurity is provided, improve the insulating oil filter of insulating oil purity.
The technical solution adopted for the present invention to solve the technical problems is: a kind of insulating oil filter, by inlet valve, coarse filter, vacuum receiver, oil pump, fine filter connects by pipeline with delivery valve, be connected with heater on described vacuum receiver, be provided with oil mist separator between vacuum receiver and oil pump, be provided with oil return valve at coarse filter and fine filter.
Further, described heater is connected with temperature sensor.
Further, be provided with fluid level control valve, spraying element and cursory in described vacuum receiver, be provided with vacuum meter, observation window and air admission valve outside vacuum receiver.
Further, described oil mist separator is provided with and vacuumizes interface and vavuum pump.
Further, be provided with flow switch between described inlet valve and coarse filter.
Further, described fine filter is provided with Pressure gauge.
Further, be provided with sample valve between described fine filter and delivery valve.
The invention has the beneficial effects as follows: the present invention is simple in structure, and is easy to use, can fully filter the impurity of insulating oil, improved purity and the performance of insulating oil, extended the service life of insulating oil, reduced the extent of deterioration of oil-using units.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is structural representation of the present invention.
1. inlet valves in figure, 2. flow switch, 3. coarse filter, 4. fluid level control valve, 5. heater, 6. temperature sensor, 7. vacuum receiver, 8. spraying element, 9. liquid level, 10. cursory, 11. oil pumps, 12. fine filters, 13. oil return valve, 14. delivery valves, 15. sample valves, 16. oil mist separators, 17. vacuumize interface, 18. vavuum pumps, 19. vacuum meters, 20.
