Hydraulic oil pass through 50 μ filters 22,20 μ filters 11, the filtering of 10 μ filters 10 successively, eventually pass back to main fuel tank, realize essence
Cleaning.Under the premise of or else influencing cleaning performance, extend 20 μ filters 11,10 μ filters, 10 service life, improves effect
Benefit.
The sample tap of pollution particle detector 2 is arranged on the pipeline that Cleaning pipes outlet connection 30 is connected to valve 7 21,
The sampling line is equipped with valve 6 20, after the completion of seminal plasma is washed, opens valve 6 20, starts pollution particle detector 2, you can realize
Sample detection；Valve 6 20 is closed in the case of remaining, then does not interfere with the safety of pollution particle detector 2.
Pressure testing pump loop consists of the following parts：Hydraulic test pump pressure regulator valve 31, hydraulic test pump pressure regulator valve are integrated on hydraulic test pump 16
31 manually adjustable pressure test pressures, to for the pressure testing of different requirements requirement.16 inlet port of hydraulic test pump is tried from main fuel tank oil suction
The outlet of press pump 16 is connected to 5 19 import of valve, and the outlet of valve 5 19 is respectively connected to hydraulic test pump pressure gauge 27 and Cleaning pipes inlet union
28, Cleaning pipes outlet connection 30 is connected to 25 import of valve simultaneously, and the outlet of valve 25 is directly coupled back to main fuel tank.Open valve five
19 close valve 25 and other valves, start hydraulic test pump 16, adjust hydraulic test pump pressure regulator valve 31, you can are carried out to pipe to be treated 29
Pressure testing；After reaching pressure test pressure, closes valve 5 19 and turn off hydraulic test pump 16, pressurize work can be carried out；When pressure release, it is only necessary to open
Valve 25, pressure oil liquid can return to main fuel tank from valve 25 is crossed.
Since pressure release cannot exclude the fluid in pipe to be treated 29, so being removed using compressed air residual in pipeline
Oil.The compressed air interface of air compressor machine 7 is connected to one 4 import of valve, and the outlet of valve 1 is connected to Cleaning pipes inlet union 28.It opens
After dynamic air compressor machine 7, open valve 1, valve 25, compressed air through valve 1, Cleaning pipes inlet union 28, pipe to be treated 29,
Remaining fluid is blown back main fuel tank by Cleaning pipes outlet connection 30, valve 25.
Excess oil recycling bins are used to receive the Residual oil flowed out when dismounting pipe to be treated 29, the connection of 6 inlet port of excess oil recovery pump
To excess oil recycling bins, the outlet of excess oil recovery pump 6 is connected to 9 24 import of valve, the outlet of valve 9 24 be connected to 50 μ filters 22 into
Mouthful.After starting excess oil recovery pump 6 in this way, in excess oil recycling bins excess oil can by excess oil recovery pump 6, valve 9 24, using it is thick,
50 μ filters 22 that seminal plasma is washed, 20 μ filters 11,10 μ filters filtering 10, eventually pass back to main fuel tank.
A pipeline is connected before 3 14 import of valve and behind the outlet of valve 7 21, valve 4 17 is installed thereon, is not cleaning outside
When pipeline only carries out self-loopa cleaning fuel tank inner fluid, valve 3 14, valve 7 21 can be closed, valve 4 17 is opened, opens cleaning pump 8,
So that fuel tank inner fluid is conveyed by cleaning pump 8 in this way, is directly over 50 μ filters 22,20 μ filters 11,10 μ filters, 10 mistake
Filter eventually passes back to main fuel tank, self-loopa cleaning is realized, to ensure cleanliness of hydraulic oil in main fuel tank.
