Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of multifunction hydraulic cleaning filtering vehicle, car body is prior art, therefore is not elaborated, in figure
Also it does not show.The system structure and operation principle of multifunction hydraulic cleaning filtering vehicle are as follows：
(1) oil return filter cleaning process
The oil return opening of back leakage connection is connected with the hydraulic system of required filtering, fluid through oil return shut-off valve 13, then according to
It is secondary through return flow meter 32, meter out valve 34, return pressure table 1, magnetic filter 11, coarse filter 10, return pressure
Table 29, radiator 8 enter main fuel tank 24.The flow-rate adjustment of reflux course is realized by adjusting meter out valve 34, and by returning
Oil flowmeter 32 is observed.The outlet of oil return shut-off valve 13 samples shut-off valve 30 through oil return and 2 31 connecting detection of pressure reducing valve fills
It sets.Oil return samples shut-off valve 30, pressure reducing valve 2 31, return flow meter 32, meter out valve 34 and return pressure table 1 and forms
Oil return detection mouth 12.
(2) fuel-displaced filtering cleaning process
The oil outlet of delivery connection is connected with the hydraulic system of required filtering.Start fuel-displaced filter oil pump motor group 20,
Fluid through main fuel tank oil absorption filter 23 to fuel-displaced filter oil pump, then in turn through fuel-displaced pressure gauge 1, fine filter 18,
Adjustable filtering precision circuit 42 (fine filter 18 to the oil circuit between fuel-displaced pressure gauge 29), fuel-displaced pressure gauge 2 29, fuel-displaced section
Stream valve 28 goes out oil flowmeter 27, goes out the hydraulic system that oil cut-off valve 15 reaches required filtering；Go out the outlet of oil flowmeter 27 through going out
Oil sampling shut-off valve 25 and one 26 connecting detection device of pressure reducing valve.Fuel-displaced filter oil pump exit is limited equipped with pilot operated compound relief valve 21
Determine the pressure of fuel feeding, the outlet of pilot operated compound relief valve 21 connects main fuel tank；Fuel-displaced pressure gauge 2 29 is for verifying pilot operated compound relief valve 21
The charge oil pressure of restriction；Flow is adjusted by fuel-displaced throttle valve 28, and is observed by going out oil flowmeter 27.When need
When wanting flushing of hydraulic system, fuel-displaced filter oil pump outlet pressure and flow are just properly increased, fluid passes through when charge oil pressure is excessively high
Safety valve 22 flows back to main fuel tank, ensures the safety of work.Fuel-displaced sampling shut-off valve 25, goes out oil flowmeter 27, goes out pressure reducing valve 1
Oily throttle valve 28 and fuel-displaced pressure gauge 29 form fuel-displaced detection mouth 16.
Shut-off valve 1 is set between the outlet of oil return shut-off valve 13 and the entrance for going out oil cut-off valve 15；Oil return filter cleans
In process and fuel-displaced filtering cleaning process, shut-off valve 1 is in off state；Shut-off valve 1 is opened, 13 He of oil return shut-off valve
When going out the closing of oil cut-off valve 15, the circulating filtration of filtering vehicle internal oil may be implemented.
(3) adjustable filtering precision circuit is filtered the process of accuracy selection
(1) two-bit triplet reversal valve 1 and two-bit triplet reversal valve 2 39 are placed in right position simultaneously, you can realize fluid
Without special fine filter：Fluid is first through two-bit triplet reversal valve 1, then through two-bit triplet reversal valve 2 39, due to check valve
One 35 effect can only flow to oil outlet；
(2) two special fine filter series connection：Two-bit triplet reversal valve 1 is placed in right position, by two-bit triplet reversal valve 2 39
It is placed in left position, is closed at shut-off valve 2 36, fluid is first through two-bit triplet reversal valve 1, then through two-bit triplet reversal valve two
39, since shut-off valve 2 36 closes the collective effect with check valve 2 40, special fine filter 2 38 can only be flowed to, then passes through spy
Fine filter 1 flows to oil outlet by check valve 1；
(3) two special fine filters are in parallel：Two-bit triplet reversal valve 1 is placed in left position, opens simultaneously shut-off valve 2 36,
Then fluid flows to special fine filter 1 and special fine filter 2 38, by list simultaneously first through two-bit triplet reversal valve 1
Oil outlet is flowed to valve 1.
(4) detection process
Detection device 17 include detection case, flusher, laser particle detector, humidity sensor, processor, keyboard and
Display.It should first be rinsed before use：Petroleum ether is passed through to detection case and laser particle detector and humidity using flusher
The gauge head of sensor is cleaned, and keeps rinsing at least 1 minute or at least through the petroleum ether of 200ml to exclude last survey
Remaining any air or liquid are tried so that it is guaranteed that sample room does not have cross contamination.Laser particle detector is opened to select by keyboard
The operating mode under a kind of filtering accuracy is selected, avoids early warning that mistake occurs.
When without detection, oil return sampling shut-off valve 30 and fuel-displaced sampling shut-off valve 25 are turned off；Detect oil return filter essence
When spending, first opens oil return and sample shut-off valve 30, fluid enters detection case through pressure reducing valve 2 31, and the effect of pressure reducing valve 2 31 is to avoid
High pressure oil causes damages to detection device, and oil return sampling shut-off valve 30 is closed after sampling；Similarly, when detecting fuel-displaced filtering accuracy,
Fuel-displaced sampling shut-off valve 25 is first opened, fluid enters detection case through pressure reducing valve 1, and fuel-displaced sampling shut-off valve 25 is closed after sampling.
Laser particle detector detects the particulate matter quantity in fluid, and humidity sensor detects the relative humidity (water in fluid of fluid
Percent by volume), data are transmitted to processor by laser particle detector and humidity sensor, and processor divides fluid
Analysis, when the relative humidity of particulate matter quantity or fluid reaches the predetermined value under different filtering accuracies, the report that is connect with processor
Alarm device is alarmed automatically.Testing result real-time display over the display, display result provide ISO, NAS, AS4059E-2 and
AS4059E-1 multiple standards, English, Italian, French, German and Chinese multilingual, to adapt to different industries and difference
The needs in area.Processor provides interface and is connected with computer, stores data into computer, so as to by the data obtained and
Database compares, and analyzes the required hydraulic system present situation filtered, predicts source of leaks, helps staff's debugging.
Detection device is arranged, and there is the automatic discontinuous property detection function of progress, i.e. laser particle detector to complete flushing, inspection
Automatically the detection in next period is carried out after survey, a cycle of interval stand-by period, it is of course possible to which the setting interval stand-by period is 0
~60min is differed.
Laser particle detector can be closed when not detecting, and detection case and laser particle detector and humidity are passed before closing
The gauge head of sensor is cleaned, and ensures accuracy of detection.
(5) oil replenishing process
When requiring supplementation with fluid, start fuel reserve tank Oil pump electrical machinery group 4, the fluid in fuel reserve tank 1 is inhaled through fuel reserve tank successively
Oil strainer 3, fuel reserve tank oil pump enter main fuel tank 24, observe the liquid level gauge 7 at main fuel tank, and fuel reserve tank oil is closed when oil mass is suitable
4 fuel cut-off of pump motor group.Thermometer 5 and air cleaner 6 are additionally provided at main fuel tank.Oil storage is set at fuel reserve tank fuel pump outlet
