China's name republic's power industry standard " granularity limit value in the transformer oil " (DL/T 1096-2008) regulation: 500kV and above AC transformer oil particles degree should be controlled at: before putting into operation in (after the Circulation and Hot Oil Spray) 100mL oil the granule number greater than 5 μ m be less than or equal to 2000, during operation in (after containing overhaul) 100mL oil the granule number greater than 5 μ m be less than or equal to 3000.(after the Circulation and Hot Oil Spray) granularity should be controlled at before 500kV and above DC converter transformer put into operation: the granule number greater than 5 μ m in the 100mL oil is less than or equal to 1000.Require highlyer in the practical application, the granule number greater than 5 μ m in the 100mL oil is less than or equal to 500, namely reaches in the NAS1638 fluid more than 1 grade standard in the particle contamination grade scale.
In order to reach the granularity index, the mode that generally adopts multiple stage circulation to filter.The realization that normally a plurality of filters is together in series of traditional multistage filtering, its external connecting pipe road is many and complicated, inconvenient operation; System's dead volume is large, and oily wastage is large.The circulating filtration mode of oil filter namely is filled into the B tank from the A tank with oil, and then is filled into the A tank from the B tank, so repeatedly, generally need circulation 3 times or more than.When two tanks switch mutually, pipeline need to be switched, the waste of fluid and again pollution can be caused.
Summary of the invention
The purpose of this utility model is to provide a kind of efficient oil filter, and it is many and complicated to have solved the external connecting pipe road, inconvenient operation; System's dead volume is large, the problem that oily wastage is large.Realized the Lectotype Optimization of simple in structure, oil filter internal unit and pipeline, circulating filtration is finished in the oil filter internal system, need not frequent tank switching and can realize continuous filtration.
The utility model overcomes the above problems the technical scheme that adopts: 1. adopt a kind of high-efficiency multi-stage filter, the three-stage filtration medium is integrated in the filter filter housing, connect thereby reduce exterior line, reduce system's dead volume; 2. inner at oil filter, filter outlet is linked to each other with the pump entry pipeline, the middle control valve of installing, in running, by adjusting the aperture of control valve, the filtering traffic that makes filter is 2~3 times of the oil filter working flow, thereby makes into the transformer oil not up to standard of oil filter once up to standard after the oil machine after filtration.
The utility model comprises inlet valve 1, cartridge filter 2, circulating pump 3, pump discharge control valve 4, filter inlet flowmeter 5, filter inlet pressure sensor 6, high-efficiency multi-stage filter 7, filter outlet pressure sensor 8, interior circulating regulation valve 9, interior circular flow meter 10, sample valve 11, outlet valve 12.Wherein.Inlet valve 1, cartridge filter 2, circulating pump 3, pump discharge control valve 4, high-efficiency multi-stage filter 7, outlet valve 12 interconnects successively, pipeline between pump discharge control valve 4 and high-efficiency multi-stage filter 7 is equipped with filter inlet flowmeter 5 and filter inlet pressure sensor 6, pipeline between high-efficiency multi-stage filter 7 and outlet valve 12 is equipped with filter outlet pressure sensor 8 and sample valve 11, pipeline between inlet valve 1 and the cartridge filter 2 is connected by pipeline with pipeline between high-efficiency multi-stage filter 7 and the outlet valve 12, form inner loop pipeline, at inner loop pipeline interior circulating regulation valve 9 and interior circular flow meter 10 are installed.
High-efficiency multi-stage filter 7 described in the utility model comprises filter housings 70, filter inlet 71, first order filter core 72, second level filter core 73, third level filter plate 74 and filter outlet 75.Wherein, first order filter core 72 is organic large traffic filtering core, and filtering accuracy is 5~10 μ m, and second level filter core 73 is organic secondary filter core, and filtering accuracy is 0.45~1 μ m, and third level filter plate 74 is the metal sintering filter plate, and filtering accuracy is 1~10 μ m.First order filter core 72 is used for the interception large granular impurity, and second level filter core is used for interception granule impurity, and third level filter core is used for the filter material that interception second level filter core may come off, and prevents the fluid secondary pollution.
Filter inlet flowmeter 5 described in the utility model is used for measuring the working flow of high-efficiency multi-stage filter 7, interior circular flow meter 10 is used for measuring the interior circular flow of oil filter system, during normal operation, filter inlet flowmeter 5 readings are greater than the reading of interior circular flow meter 10, and the difference of the two is the working flow of oil filter.During normal operation, the aperture of circulating regulation valve 9 in regulating, the reading that makes filter inlet flowmeter 5 is 1.5~2 times of reading of interior circular flow meter 10, this moment, the working flow of filter was 2~3 times of oil filter working flow.Because the existence of interior circulation, after transformer oil enters oil filter, be equivalent to the filter effect of circulating filtration 2~3 times.
The utility model has adopted high-efficiency multi-stage filter, has realized three-stage filtration at a filter, has reduced system pipeline and has connected and system's dead volume, has reduced the fluid loss; Simultaneously because the existence of interior circulation, the fluid that enters oil filter is once filtered to reach the filter effect of circulating filtration 2~3 times, thereby really realized continuous filtration.The utility model is not only applicable to the filtration of transformer oil, also is applicable to the cleaning filtration treatment of various hydraulic oil, machine oil etc.
