Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of motor low pressure oil way test system as shown in Figure 1, test system is connected to by pipeline on the gear pump 4 and high pressure co-rail system 7 of motor by fuel tank 1, the first valve 2, strainer 3, the second valve 5, secondary filter 6, pipeline is provided with the sensor that gathers oil circuit pressure, flow, temperature and granule number, and sensor is connected with the input end of controller.
Sensor comprises the first pressure transmitter 8 arranging between fuel tank 1 to first valve 2, the first temperature transmitter 9, the first sample point 10, the first oil return point 11, also comprise the second pressure transmitter 12 arranging between strainer 3 and gear pump 4, also comprise the 3rd pressure transmitter 21 between gear pump 4 and the second valve 5, the second sample point 13, the second oil return point 14, also comprise the 3rd sample point 15 arranging between secondary filter 6 and high pressure co-rail system 7, the 3rd oil return point 16, the 4th pressure transmitter 17, first flow meter 18, also comprise the second temperature transmitter 19 arranging between high pressure co-rail system 7 and fuel tank 1, the second flowmeter 20, the first sample point 10 and the first oil return point 11 are connected with the first particle collector, the second sample point 13 and the second oil return point 14 are connected with the second particle collector, the 3rd sample point 15 and the 3rd oil return point 16 are connected with the 3rd particle collector.
Between the outlet of the import of the first valve 2 and strainer 3, bypass has the first pipeline, and the first pipeline is provided with first bypath valve 21 in parallel with the first valve 2; Between the outlet of the import of the second valve 5 and secondary filter 6, bypass has the second pipeline, and the second pipeline is provided with second bypath valve 51 in parallel with the second valve 5.The first bypath valve 21 and the second bypath valve 51 are situations of only having a filter for motor, now, close arbitrarily a bypath valve, need only so can form a test system.
Working principle of the present utility model is as follows:
In the time that motor moves, gear pump entry into service, oil is extracted out and is entered system pipeline from fuel tank, the first pressure transmitter and the first temperature transmitter are measured respectively the pressure and temperature that enters the diesel oil of pipeline from fuel tank, the first particle collector accesses the first sample point and the first oil return point, measures the primary particles number of diesel oil.The outlet pressure of the second pressure transmitter measurement strainer, be the inlet pressure of gear pump, the outlet pressure of the 3rd pressure transmitter measurement gear pump, the i.e. inlet pressure of secondary filter, the second particle collector accesses the second sample point and the second oil return point, measures the import granule number of secondary filter; The 3rd particle collector access the 3rd sample point and the 3rd oil return point, the outlet granule number of measurement secondary filter; The outlet pressure of the 4th pressure transmitter measurement secondary filter, the oil-feed flow on first flow instrumentation buret road, the second temperature sensor measurement returning-oil temperature; The oil return flow of second flowmeter measurement pipeline.By above-mentioned signal feed back, to controller, controller can calculate the pressure reduction of fuel consumption, strainer and the secondary filter of motor, and the filter efficiency of strainer and secondary filter.
