Advantage and effect that the utility model has are:
1, the utility model circulation air draft self-sucking device is after starting mode of pump, pressure reduction by means of upper and lower two chambeies, make the water of epicoele to pass through at a high speed backwater air inducing injection pipe, and the air in suction sleeve is drawn into sparger through air inducing conduit, injected current ooze and mix cavity of resorption again immediately, due to water pump continuous operation, cause water upper and lower iterative cycles in circulating exhaust self-sucking device, finally make all air in system all at epicoele, obtain air-water separation and go in being discharged into nature by auto-control exhaust device.In water, not containing air, water pump head pressure rises naturally, goes grid-connected after pressure is up to standard again.
2, the volume of the utility model circulation air draft self-sucking device is little, and cost is low, wide accommodation.
3, the utility model circulation air draft self-sucking device pulls double duty, and air draft draining separately again is separately applicable to have the large pumping station use of many centrifugal water pumps.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram;
Fig. 2 is the structural representation of auto-control exhaust device in the utility model;
Fig. 3 is that the utility model is used view.
In figure: suction sleeve 1, water injecting pipe gland 2, water guide cap 3, auto-control exhaust device 4, air inducing conduit 5, return water wind shield 6, backwater air inducing injection pipe 7, sparger 8, circulation intake pipe 9, dividing plate 10, tank body 11, outlet pipe 12, gravity check valve 43, sealing pad 44, shell 45, floating drum 46, seal washer 47, floating drum collet 48, circulation air draft self-sucking device 24, circulation regulation and control gate valve 19, safety check 20, production water supply gate valve 21, centrifugal pump 22, motor 23.
Embodiment
As shown in Figure 1, the utility model circulation air draft self-sucking device, include tank body 11, tank interior is provided with water guide cap 3 and dividing plate 10, water guide cap 3 welds mutually tank body is divided into dividing plate 10, lower two chambeies, tank body top is provided with auto-control exhaust device 4, tank body epicoele inside is provided with returns water wind shield 6, the outside side of tank body epicoele is connected with water injecting pipe gland 2, the outside opposite side of tank body epicoele is provided with circulation intake pipe 9, the position that tank body cavity of resorption outside is positioned at circulation intake pipe 9 belows is provided with outlet pipe 12, the below of water guide cap 3 is provided with suction sleeve 1, suction sleeve 1 is connected with sparger 8 by air inducing conduit 5, sparger 8 is by upper, lower two chambeies connect, in sparger 8, be provided with backwater air inducing injection pipe 7, the top of backwater air inducing injection pipe 7 is placed in to be returned in water wind shield 6.
As shown in Figure 2, described auto-control exhaust device 4 includes gravity check valve 43, sealing pad 44, shell 45, floating drum 46 and floating drum collet 48, shell 45 is connected with tank body 11 by flange, floating drum collet 48 is arranged on the top of tank body, floating drum 46 is placed on floating drum collet 48, the top of floating drum 46 is provided with sealing pad 44, and the top of shell 45 is provided with gravity check valve 43.
Shell 45 is provided with seal washer 47 with the joint of tank body 11.
Below in conjunction with Fig. 3, using method of the present utility model and working principle thereof are described below:
1, check periodical feeding gate valve 19, and open it; Production water supply valve 21 is closed simultaneously.
2, open water injecting pipe gland 2, and fill with water in pipe, then gland is tightened.
3, start water pump, allow water iterative cycles between the epicoele of circulating exhaust self-sucking device and cavity of resorption.Water enters water pump from the cavity of resorption of exhaust self-sucking device, flows into again subsequently the epicoele of air draft self-sucking device from exit of pump, will cause epicoele water level constantly to rise, and end cavity pressure constantly declines, thereby formed the pressure reduction between two chambeies, and this pressure reduction can strengthen again gradually.
4, because the former water of epicoele is few, and space is larger, so water is slower in epicoele flowing velocity, so the time that water stops at epicoele is longer, for gas, water separation provide abundant guarantee.The air being separated, has again certain pressure, just can go back to nature by the auto-control exhaust device 4 on top.
5,, when the epicoele water surface surpasses backwater air inducing injection pipe 7, epicoele water will turn back to chamber, the end with the core pipe 7 by backwater wine guide at a high speed.Just because of this draw attached effect continue carry out, the air in the suction sleeve 1 of the air draft self-sucking device that makes to circulate, by air inducing conduit 5 by injection to cavity of resorption, then by water pump, be transported in epicoele and go again.Due to by this upper and lower circulation repeatedly, all air in suction sleeve are all discharged in atmosphere and are gone successively the most at last.
6, in the water pump periodic duty stage, during beginning, can hear that air is from the sound of auto-control exhaust device top discharge, when air is drained, sound just stops automatically, at this moment can implement formal and net operation.
7, close periodical feeding gate valve 19, and then open production water supply gate valve 21 and just can go into operation smoothly.
In conjunction with Fig. 2, Fig. 3, the function of auto-control exhaust device is described:
If water level rises in air exhausting device shell, must cause floating drum 46 levitatings, when being raised to top, sealing pad 44, by end in contact under the outlet pipe with gravity check valve lower end, stops air draft.
When circulation air draft self-sucking device quits work, in auto-control exhaust device, in negative pressure state, at this moment gravity check valve 43 wants definitely tight, the inaccurate gas leak phenomenon that produces.
