When testing equipment needs to put into operation, electric-control system receives the pressure of testing stand request, flow in oil supply system,
The operating pressure of the automatic Set scale plunger pump 2 of control system.2 oil liquid of ratio plunger pump is driven to pass through from fuel tank 1 by motor 3
Pump group conveying high-pressure filter 7,7 band 75% of high pressure filter, 100% differential pressure transmitter device, the filter core pressure at two ends of high pressure filter 7
Pre-alarm prompting changing filter core when difference reaches the 75% of preset value, fault alarm is shut down in system when pressure difference reaches 100%.By
Oil liquid leads to big flow ability into the first having for the inserting inserting composition of valve cover 11 of valve core 10, first after high pressure filter 7
Check valve.First pressure sensor 9 is housed between high pressure filter 7 and the first inserting valve core 10, it is single for measuring
The pressure value of pump group outlet, converts the measurement into 4 ~ 20mA signal and is sent to electric-control system.Electromagnetic relief valve 8 in systems when
Safety valve use is done, is normally opened form, energy idle running plays a protective role to pump up to stablizing before so that plunger pump 2 is built pressure.
Flow sensor 4, temperature sensor 5, check valve 6 are equipped in the leakage hydraulic fluid port of plunger pump；Pump its Leakage Energy in normal work
Flow and temperature maintain essentially within a fixed section；When leakage both oil stream amount or temperature one occurs suddenly
When the trend of the oriented non-ideal direction change of trend of variation or collection value, switching pump group, maintenance down are reminded.
According to the flow for device request of giving a banquet, the number of units of pump group is opened in system control, according to hydraulic oil source system support
The maximum value of the demand volume of testing equipment, system can be made of multiple pump groups.Oil is passed through pipeline to test by pump group
Equipment takes oil drop valve group, takes the setting quantity of oil drop valve group according to depending on testing equipment.Take oil drop valve group mainly by pressure measuring tie-in
15, solenoid directional control valve 16, second inserts valve cover 17, second and inserts valve core 18, second pressure sensor 19, oil-feed port ball valve
20, drain tap ball valve 21, oil return opening ball valve 22 and valve block composition.Oil liquid is sensed before supplying testing equipment by second pressure
Device 19 detects its actual pressure value and is compared with first pressure sensor 9, due to having the pressure loss in oil liquid transmission process, leads to
Cross the difference for comparing and both calculating and adjust the discharge pressure of ratio plunger pump 2 in real time, until 19 pressure of second pressure sensor with
Experimental facilities value request is consistent.
When normal work, the fuel feeding for taking oil drop valve group corresponding with there is demand testing equipment, oil return, drain tap ball are opened
Valve, oil liquid enter testing equipment, the oil return of testing equipment and draining by taking the ball valve in oil drop valve group by two-way plug-in valve
It is flowed with pipeline to fuel tank direction.Oil liquid flows through check-valves 14, return filter 13 enters fuel tank, same 13 band of return filter
75%, 100% differential pressure transmitter device, pre-alarm is reminded more when the filter core pressure at two ends difference of return filter 13 reaches the 75% of preset value
Filter core is changed, fault alarm is shut down in system when pressure difference reaches 100%.In view of testing equipment demand volume can constantly change, oil
Liquid can the form of mist of oil diffuse to equipment room by air filter 24, therefore Oil-mist fan 12, fuel tank 1 are set on fuel tank 1
Internal mist of oil handles oil liquid by Oil-mist fan 12 and is back to fuel tank 1, can effectively prevent the pollution of air.
When occurring pipeline breaking between oil supply system and any experimental facilities or other emergency cases need to cut off oil liquid, and
It is not desired to influence the work of other experimental facilities again, pressure value can be detected by second pressure sensor 19 and be less than minimum set value,
Solenoid valve 16 is obtained by electric-control system electric, close two-way plug-in valve.
It is different from the prior art, the utility model Intelligent constant-voltage oil supply system, is provided using Prop-pressure control plunger pump
Pressure is arranged needed for requesting pressure independently to judge according to testing stand by being communicated with each testing stand in hydraulic power supply；Pass through
Take oil drop valve group outlet pressure sensor value of feedback compared with testing stand value request, adaptive control system Setting signal, most
Whole set-pressure value is testing stand value request.Consider that vehicle body of railway vehicle test is continuity test, in system dynamic core ratio
Flow, temperature sensor are set on example pressure control plunger pump drain line, are compared by the value of detection with theoretical value, or
Person is prejudged by judging acquisition flow, temperature value the service condition of plunger pump in the variation tendency of certain specific time
Switch the operation of other plunger pump groups, reminds maintenance, guarantee to provide oil sources steadily in the long term for testing equipment.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
