Specific embodiment
The particular content of the utility model is described in detail with reference to attached drawing.A kind of filter element circulating resistance test device, edge
Test(ing) medium transmission direction is equipped with oil absorption filter 2, oil transfer pump 4, in-line filter 5, the pressure gauge being connected by pipeline successively
7th, flow control valve 8, flowmeter 9, thermometer 10, manual sampling valve 20, subject filter 22 and counterbalance valve 14, oil absorption filter
2 inlets are connected by pipeline with experiment 1 liquid outlet of fuel tank, and 14 liquid outlet of counterbalance valve passes through pipeline and experiment 1 inlet of fuel tank
Be connected, be connected separately on the pipeline of subject filter 22 both sides the pressure difference in parallel with the subject filter 22 test pipeline and
Line particle contamination monitored pipeline, pressure difference testing tube road are equipped with differential manometer 11 and pressure gauge 12, online particle contamination monitored pipeline
On successively be equipped with automatic sampling switching valve 21, online particle contamination monitor 23 and automatic sampling switching valve 21, be tested filter
22 lower part is equipped with the collecting tank 13 being connected with experiment fuel tank 1, is set on the pipeline between in-line filter 5 and flow control valve 8
There is the overflow passage being connected with experiment fuel tank 1, which is equipped with overflow valve 6, and the experiment fuel tank 1 is equipped with to control
The cooler 17 of test(ing) medium temperature and heater 19 in system experiment fuel tank 1, the cooler 17 are connected with cooler control valve 18,
It tests fuel tank 1 and is equipped with thermometer, breathing circuit filter 15 and fluid level controller 16.
The operation principle of the utility model is：Test(ing) medium in experiment fuel tank 1 is filtered out larger by oil absorption filter 2
Solid particle plays the role of protecting oil transfer pump 4, and test(ing) medium enters in-line filter 5 by oil transfer pump 4 and further purifies
Test(ing) medium, the cleannes grade for test(ing) medium being made to reach test request by replacing filter core therein, passes through overflow valve 6
To meet the pressure of test system, and test(ing) medium pressure is shown by pressure gauge 7, adjusted by flow control valve 8 full
The test flow required enough, and record and show by flowmeter 9, thermometer 10 shows access into the experiment of subject filter 22
