Accompanying drawing explanation
Fig. 1 is the structural representation of low pressure filtration system of the present invention in a specific embodiment.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Alleged " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the present invention herein.Different local in this manual " in one embodiment " that occur not all refer to same embodiment, neither be independent or the embodiment mutually exclusive with other embodiments optionally.
Refer to Fig. 1, Fig. 1 is the structural representation of low pressure filtration system of the present invention in a specific embodiment.Described low pressure filtration system comprises fuel tank 1, high-pressure service pump 2, valve means 3, master cylinder 4, oil well pump 5, heat exchanger 6 and filter 7.
Described fuel tank 1 comprises the first seal area 11, the second seal area 12 and the dividing plate 13 of isolating described the first seal area 11 and the second seal area 12.The pipeline being connected with the input end of described high-pressure service pump 2 stretches into the bottom of close fuel tank 1 in described the first seal area 11, the pipeline being connected with the input end of described oil well pump 5 stretches in described the second seal area 12 bottom near fuel tank 1, to guarantee that liquid in fuel tank 1 also can be extracted when less.In this embodiment, the liquid in described fuel tank 1 is oil, in other embodiments, the kind of liquid in fuel tank 1 is not limited.In one embodiment, the top of described fuel tank 1 is provided with sealing cover (not shown), to prevent that dust impurity from falling into fuel tank 1.
The input end of described high-pressure service pump 2 is connected with described the first seal area 11 by pipeline, and the output terminal of described high-pressure service pump 2 is connected with valve means 3 by pipeline.Oil in the first seal area 11 is extracted out and is become high pressure oil by pressurization through high-pressure service pump 2, and in this embodiment, the quantity of described high-pressure service pump 2 is three, and in other embodiments, the quantity of described high-pressure service pump 2 can be adjusted according to the pressure of needs of production high pressure oil.
One end of described valve means 3 is connected with the output terminal of described high-pressure service pump 2 by pipeline, and the other end of described valve means 3 is connected with described master cylinder 4 by pipeline.In described valve means 3, be provided with valve (not shown), by controlling this valve capable of regulating, enter the amount of the high pressure oil in described master cylinder 4, to meet needs of production.
One end of described master cylinder 4 is connected with described valve means 3 by pipeline, and the other end of described master cylinder 4 is connected with described the second seal area 12 by pipeline.Wherein, described master cylinder 4 is connected with outside other machines, and high pressure oil enters the motion with promotion other machines by master cylinder 4 in master cylinder 4.
The input end of described oil well pump 5 is connected with described the second seal area 12 by pipeline, and the output terminal of described oil well pump 5 is connected with described heat exchanger 6 by pipeline.The power of described oil well pump 5 is less than the power of described high-pressure service pump 2, and in this embodiment, the quantity of described oil well pump 5 is one, and the quantity of described high-pressure service pump 2 is three, therefore large through the oily pressure of described oil well pump 5 through the oily pressure ratio of described high-pressure service pump 2.When oil well pump 5 and high-pressure service pump 2 extract the oil in described the second seal area 12 and the first seal area 11 respectively simultaneously, there will be very fast that oil in the first seal area 11 taken out, and that oil in the second seal area 12 is taken out is very slow, thereby cause the oil spill of the second seal area 12 of fuel tank 1 to go out fuel tank 1.The present invention is provided with overfolw hole 131 on described dividing plate 13, described overfolw hole 131 is arranged on the top of described dividing plate 13 near the top of described fuel tank 1, during Chuck Steak in the second seal area 12, described overfolw hole 131 can guarantee that the oil subsidy in the second seal area 12 is charged in the first seal area 11, to guarantee having enough oil to extract for described high-pressure service pump 2 in the first seal area 11, thereby guaranteed the continuation of whole production.On described overfolw hole 131, be provided with filter screen 132, when oil enters described the first seal area 11 when interior from the second seal area 12 by overfolw hole 131, described filter screen 132 plays an effect of filtering well cuts, therefore, in the present invention, after oil in the first seal area 11 that described high-pressure service pump 2 is extracted out is filtered, the oil extracting through high-pressure service pump 2 can directly pass through valve means 3, and can blocking valve body device 3.
One end of described heat exchanger 6 is connected with the output terminal of described oil well pump 5 by pipeline, and the other end of described heat exchanger 6 is connected with described filter 7 by pipeline.The oil temperature out entering from described master cylinder 4 in the second seal area 12 of fuel tank 1 is higher, need lower the temperature through heat exchanger 6, becomes low temperature oil.
One end of described filter 7 is connected with described heat exchanger 6 by pipeline, and the other end of described filter 7 is connected with described the first seal area 11 by pipeline.The described high-pressure service pump 2 of the first interior confession in seal area 11 that low temperature oil after 7 coolings of described heat exchanger directly enters fuel tank 1 production of extracting to circulate.In this embodiment, be provided with nut (not shown) on described filter 7, the weight of described nut is for being about 10 kilograms or be greater than 10 kilograms.Because the oil through described filter 7 is low pressure oil, therefore can not cause high pressure to cause nut to fly out, guaranteed staff's safety and the efficiency of production.
In the present invention, because the power of described oil well pump 5 is less than the power of described high-pressure service pump 2, and in this embodiment, the quantity of described oil well pump 5 is one, the quantity of high-pressure service pump 2 is three and works simultaneously, therefore larger than the pressure of the oil (can be referred to as low pressure oil) through described oil well pump 5 through the oily pressure (can be referred to as high pressure oil) of described high-pressure service pump 2, and high pressure oil is relative with low pressure oil, can distinguish according to production actual conditions.
Please continue to refer to Fig. 1, the working principle of low pressure filtration system of the present invention is as follows: in Fig. 1, the direction of arrow is oily traffic direction.While starting working, described high-pressure service pump 2 starts, oil in the first seal area 11 of fuel tank 1 is extracted up by pipeline, after pressurization, by pipeline, deliver to valve means 3, by valve means 3, by pipeline, be transported to and in master cylinder 4, control machine and produce exercises again, then through the oil of pressure release, continue transported in the second seal area 12 of fuel tank 1, then by oil well pump 5,12 oil in fuel tank 1 second seal area is continued to extract out and is sent in fuel tank 1 first seal area 11 and recycles after filtering through heat exchanger 6 coolings, filter 7 again.
Low pressure filtration system of the present invention, its position by filter changes to low pressure area from zone of high pressure, makes the nut on filter can, because high pressure oil pressure is compared with being rushed to open greatly, not ensure greatly staff's personal safety, not only improve manufacturing efficiency, and obviously reduced cost of production.
Above-mentioned explanation has fully disclosed the specific embodiment of the present invention.It is pointed out that being familiar with any change that person skilled in art does the specific embodiment of the present invention does not all depart from the scope of claims of the present invention.Correspondingly, the scope of claim of the present invention is also not limited only to previous embodiment.
