Description
Technical field
The present invention relates to a kind of circulation air draft self-sucking device.
Background technique
Since synchronous self-priming pump comes out, a lot of undergrounds pump house is eliminated in succession, has thoroughly eradicated pump house by the worries of flooding, and also makes water pump in maintenance simultaneously and uses all convenient.Therefore, synchronous self-priming pump is widely used in the last few years.Along with production technology development, higher requirement be it is also proposed for production water supply.Some water places must assure feed water pressure and flow at any time, otherwise will affect quality of product, even causes production accident.And synchronous self-sucking device water pump rise the pump initial stage due to water in containing air, cause water pump head pressure on the low side, occurred grid-connected difficulty; Another then be that self-sucking device volume is comparatively large, materials its high cost on the high side; And be sometimes subject to the restriction of installation site.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of circulation air draft self-sucking device, this self-sucking device can after starting mode of pump, first allow water circulate voluntarily between the epicoele and cavity of resorption of self-sucking device, the large quantity of air had is discharged in air in cyclic process goes in suction sleeve.Not containing air in water, water pump head pressure rises naturally, goes grid-connected after pressure is up to standard again.
In order to solve prior art Problems existing, the technical solution used in the present invention is:
Circulation air draft self-sucking device, include tank body, tank interior is provided with water guide cap and dividing plate, water guide cap and dividing plate weld mutually and are divided into by tank body, lower two chambeies, tank body top is provided with auto-control exhaust device, tank body epicoele inside is provided with returns water wind shield, the outside side of tank body epicoele is connected with water injecting pipe gland, the outside opposite side of tank body epicoele is provided with circulation intake pipe, the outside position be positioned at below circulation intake pipe of tank body cavity of resorption is provided with outlet pipe, the below of water guide cap is provided with suction sleeve, suction sleeve is connected with sparger by air inducing conduit, sparger is by upper, lower two chambeies are through, backwater air inducing injection pipe is provided with in sparger, the top of backwater air inducing injection pipe is placed in be returned in water wind shield.
Described auto-control exhaust device includes gravity check valve, sealing pad, shell, floating drum and floating drum collet, shell is connected with tank body by flange, floating drum collet is arranged on the top of tank body, floating drum is placed on floating drum collet, the top of floating drum is provided with sealing pad, and the top of shell is provided with gravity check valve.

Embodiment
As shown in Figure 1, the present invention circulates 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 with dividing plate 10 and is divided into by tank body, 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 outside position be positioned at below circulation intake pipe 9 of tank body cavity of resorption 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 are through, backwater air inducing injection pipe 7 is provided with in sparger 8, the top of backwater air inducing injection pipe 7 is placed in 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 invention 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 water in pipe, then gland is tightened.
3, start water pump, allow water iterative cycles between the epicoele and cavity of resorption of circulating exhaust self-sucking device.Water enters water pump from the cavity of resorption of exhaust self-sucking device, flows into again the epicoele of air draft self-sucking device subsequently, epicoele water level will be caused constantly to rise, and end cavity pressure constantly declines, and thus defines the pressure reduction between two chambeies, and this pressure reduction can strengthen again gradually from exit of pump.
4, because the original water of epicoele is few, and space is comparatively large, so water is relatively slower in epicoele flowing velocity, therefore time of stopping at epicoele of water is longer, for gas, water separation provide abundant guarantee.The air be separated, has certain pressure again, just can be gone back to nature by the auto-control exhaust device 4 on top.
5, when the epicoele water surface exceedes backwater air inducing injection pipe 7, then epicoele water is by next to turn back to chamber, the end by the core pipe 7 of backwater wine guide at a high speed.Just because of this draw attached effect continue carry out, make the air in the suction sleeve 1 of circulation air draft self-sucking device, by air inducing conduit 5 by injection to cavity of resorption, be then transported in epicoele by water pump again and go.Due to by this upper and lower circulation repeatedly, all air the most at last in suction sleeve are all discharged in air successively and are gone.
6, in the water pump periodic duty stage, can hear the sound of air from auto-control exhaust device top discharge during beginning, when air is drained, sound just stops automatically, at this moment can implement formal also 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.
Composition graphs 2, Fig. 3, be described the function of auto-control exhaust device:
If in air exhausting device shell water level rise, floating drum 46 levitating must be caused, when being raised to top sealing pad 44 by with end in contact under the outlet pipe of gravity check valve lower end, air draft is stopped.
When circulation air draft self-sucking device quits work, be then in negative pressure state in auto-control exhaust device, at this moment gravity check valve 43 wants definitely tight, inaccurate generation gas leak phenomenon.
