Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment
Embodiment.A kind of oil hydraulic pump pilot system that can carry out oil liquid temperature control, as shown in Figure 1, comprise oil return gating integrated package 13, the piece filler opening 18 of oil return gating integrated package 13 is through return filter 7, precursor overflow valve 6 and be connected by the oil outlet of test solution press pump 5; The piece oil outlet A19 of oil return gating integrated package 13 through heating pipe line 14 be connected by the filler opening of test solution press pump 5; The piece oil outlet B20 of oil return gating integrated package 13 is connected with fuel tank 1 through cooling line 15, water-filled radiator 16; Filler opening place by test solution press pump 5 is provided with temperature transducer 3; Also be connected with fuel tank 1 by the filler opening of test solution press pump 5 through oil suction filter 2.Oil return gating integrated package 13 comprises fixing body 17, and fixing body 17 bottoms are provided with piece filler opening 18, and piece filler opening 18 is connecting two-way plug-in valve door A10 and two-way plug-in valve door B11; Two-way plug-in valve door A10 is connecting control cover plate A9 and piece oil outlet B20, and two-way plug-in valve door B11 is connecting control cover plate B12 and piece oil outlet A19; Solenoid directional control valve 8 is connecting control cover plate A9.
During use, after precursor overflow valve 6 loads,, got into the piece filler opening 18 of oil return gating integrated package 13 through return filter 7 by the fluid of test solution press pump 5 outflows.When temperature transducer 3 detected by test solution press pump 5 imports oil temperature be lower than that temperature controlling instrument is provided with following in limited time; Solenoid directional control valve 8 is connected; Solenoid directional control valve P mouth communicates with the B mouth; The fluid that is flowed into by piece filler opening 18 acts on the spool epicoele of two-way plug-in valve 10 through the control port X of control cover plate 9 mouth, solenoid directional control valve P mouth, B mouth, causes two-way plug-in valve 10 to open.And two-way plug-in valve 11 is equivalent to non-return valve function; Two-way plug-in valve 11 can be opened; The fluid that is flowed into by piece filler opening 18 flows out through the piece oil outlet A19 of two-way plug-in valve 11, oil return gating integrated package 13; Directly get into by the import of pump testing hydraulic pressure 5 through heating pipe line 14, form a closed cycle loop, make oily temperature rise thereby utilize overflow to load the heat that produces.Compare with oily temperature control system in the past; Overflow loads the fluid that the heat produced only supplies with in the closed circulation system pipeline and heats up, rather than the fluid of supplying with whole fuel tank heats up, in this pipeline the fluid volume that will heat compare the fuel tank actual volume; Greatly reduce; So just can shorten the time that oil hydraulic pump import fluid reaches the regulation test temperature, reduce the setup time before testing, improve test efficiency.
Be higher than going up in limited time that temperature controlling instrument is provided with when temperature transducer 3 is detected by test solution press pump 5 imports oil temperature; Solenoid directional control valve 8 breaks off; Solenoid directional control valve T mouth communicates with the B mouth; At this moment, the fluid that acts on two-way plug-in valve 10 spool epicoeles links to each other with the piece oil outlet B20 of oil return gating integrated package 13 through the control mouth Y of solenoid directional control valve B mouth, T mouth, control cover plate 9 mouth.Because the cracking pressure of two-way plug-in valve 11 is several times of cracking pressure of two-way plug-in valve 10; The spring that is two-way plug-in valve 11 is much harder than the spring of two-way plug-in valve 10; Therefore the fluid that flows into from piece filler opening 18 only can be opened two-way plug-in valve 10, and fluid flows out from piece oil outlet B20, gets into water-filled radiator 16 through cooling line 15; Fluid is cooled off, and fluid gets into fuel tank at last.
When oily temperature drop to the lower limit temperature set up, solenoid directional control valve 8 switch on again, and two-way plug-in valve 10 is closed, and two-way plug-in valve 11 is opened, and fluid returns oil hydraulic pump import completion closed cycle heating process by piece oil outlet A19.
