The pneumatic cold filtration of above-mentioned development machine system, wherein, described power unit comprises pneumatic motor and gear pump; The main shaft of described gear pump links to each other with the output shaft of pneumatic motor; Described gear pump is arranged between oil suction filter and the cooler, the linking to each other with the outlet of filter, the import of condenser by oil pipe respectively into and out of hydraulic fluid port of gear pump.
The pneumatic cold filtration of above-mentioned development machine system, wherein, the pneumatic cold filtration of this development machine system also comprises safety valve, and described safety valve two ends are respectively by linking to each other with the gear pump oil outlet with the gear pump inlet port.
The pneumatic cold filtration of above-mentioned development machine system, wherein, the pneumatic cold filtration of this development machine system also comprises silencing apparatus, and described silencing apparatus is arranged on the pneumatic motor steam outlet pipe.
The pneumatic fuel tank cooling system of the utility model development machine compared with prior art has the following advantages:
The utility model drives pneumatic motor because what adopt is pneumatic motor by the down-hole wind energy, makes the development machine cold filtration system can be independently and outside the development machine hydraulic system.
The utility model can pass through corresponding valve core spring restriction system maximum pressure owing to be provided with safety valve, prevents that system pressure is too high, washes out cooler.
The utility model can reduce the noise in pneumatic motor outlet port owing to be provided with silencing apparatus.
The utility model can carry out coarse filtration and protect gear pump simultaneously owing to be provided with the oil suction filter to the fluid that fuel tank comes out; Be provided with return filter, can fluid recycled, economize on resources, reduce entreprise cost, increase economic efficiency by the highi degree of accuracy gauze element to smart filtration of fluid that gear pump comes out.
Embodiment
Below in conjunction with Fig. 1 the utility model is further elaborated.
As shown in Figure 1, the pneumatic fuel tank cold filtration of development machine system comprises fuel tank 6, filter element 2, power unit 3 and cooler 5.Filter element 2 comprises oil suction filter 21 and return filter 22; oil suction filter 21 is arranged between fuel tank 6 and the cooler 5; advancing of oil suction filter 21; outlet by oil pipe respectively with the outlet of fuel tank 6; the import of cooler 5 links to each other; can by precision be 100 μ m the fibrous web-like filter core to the fluid coarse filtration and the protection gear pump 32; return filter 22 is arranged between cooler 5 and the fuel tank 6; advancing of return filter 22; outlet by oil pipe respectively with the outlet of cooler 5; the import of fuel tank 6 links to each other, and can filter the fluid essence that gear pump 32 comes out by the highi degree of accuracy gauze element.Power unit 3 is made up of TMY series pneumatic motor 31 and gear pump 32, the main shaft of gear pump 32 links to each other with the output shaft of pneumatic motor 31, gear pump 32 is arranged between oil suction filter 21 and the cooler 5, the linking to each other with the outlet of oil suction filter 21, the import of cooler 5 by oil pipe respectively into and out of hydraulic fluid port of gear pump 32.Cooler 5 is the water-cooled cooler, and cooling water is provided by the water system of down-hole, and system is cooled off.The pneumatic fuel tank cold filtration of this development machine system also comprises safety valve 4 and silencing apparatus 1, wherein, the two ends of safety valve 4 link to each other with oil outlet with gear pump 32 filler openings by oil pipe respectively, by corresponding valve core spring restriction system maximum pressure, prevent the too high damage gear pump 32 of system pressure, silencing apparatus 1 is arranged on pneumatic motor 31 steam outlet pipes, can reduce the noise of pneumatic motor 31 outlets.
As shown in Figure 1, during the utility model The field, pneumatic motor 31 drives by the wind energy from the down-hole, thereby driven gear pump 32 runnings, make fluid pass through oil pipe, enter oil suction filter 21, gear pump 32, cooler 5, return filter 22, return fuel tank 6 at last from fuel tank 6 outlets, by native system fluid is constantly circulated like this, finish cold filtration fluid.
In sum, by application to the pneumatic fuel tank cooling system of the utility model development machine, can be convenient for development machine cold filtration process, efficient, fluid is recycled, reduce entreprise cost, increase economic efficiency.
Although content of the present utility model has been done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple modification of the present utility model with to substitute all will be conspicuous.Therefore, protection domain of the present utility model should be limited to the appended claims.
