Main reference character:
The liquid outlet of 1-horizontal centrifugal pump, 2-horizontal centrifugal pump, 3-outlet valve, 4-drain pipe, 5-liquid container, 5-1-liquid container lower openings, 5-2-liquid container upper opening, 6-liquid inlet pipe, 7-float relay, 8-float, 9-sealing gasket, 10-sloptank.
Embodiment
Hereinafter, the exemplary embodiment that combines accompanying drawing to the utility model is described in further detail.
Fig. 1 is the scheme of installation of the horizontal self-sucking pump of the utility model exemplary embodiment at sloptank.Horizontal self-sucking pump according to the utility model comprises float relay 7, liquid container 5, horizontal centrifugal pump 1.Liquid container 5 is airtight hollow vessel; The upper and lower of liquid container 5 respectively is provided with an opening; Be liquid container upper opening 5-2 and liquid container lower openings 5-1, horizontal centrifugal pump 1 is communicated with liquid container lower openings 5-1 through drain pipe 4, and drain pipe 4 is provided with outlet valve 3; Liquid container upper opening 5-2 is communicated with sloptank 10 through liquid inlet pipe 6, and wherein outlet valve 3 is used to control the liquid outflow of drain pipe.Float relay 7 is arranged in the sloptank 10 and is used to control the action of horizontal centrifugal pump 1, and when the float 8 of float relay 7 during at extreme lower position L, the control horizontal centrifugal pump is closed in the float relay; When the float 8 of float relay 7 in the extreme higher position during H, the control horizontal centrifugal pump is opened in the float relay.The joint that float relay 7 is installed in the sloptank 10 can be provided with sealing gasket 9, in case the solution stopping body flows out.
Horizontal centrifugal pump 1 is that common horizontal centrifugal pump and its can be by motor driving, and horizontal centrifugal pump 1 specifically can be single suction formula horizontal centrifugal pump or double-sucking type horizontal centrifugal pump, also can be single-stage horizontal centrifugal pump or multistage horizontal centrifugal pump, but be not limited thereto.Float relay 7 also can be common float relay, as long as can realize through the folding of changes in liquid level control switch.
It should be noted that before starting first, need in liquid container 5, fill with in advance to draw liquid that promptly liquid container 5 also is included in and starts the liquid of filling with in advance before the horizontal self-sucking pump that draws.Owing to there is the liquid of filling with that draws in the liquid container 5; When opening outlet valve 3 with horizontal centrifugal pump 1; The liquid that draws in the liquid container 5 can be earlier via liquid outlet 2 outflows of drain pipe 4, horizontal centrifugal pump, and liquid level descends in the liquid container 5, causes forming in the jar negative pressure; Liquid in the sloptank then is pressed in the liquid container 5 and by horizontal centrifugal pump via liquid inlet pipe 6 and takes away, realizes the self-priming drawing liquid.But; If the outlet conduit at the liquid outlet of horizontal centrifugal pump 2 places is shorter; When carrying out drawing liquid, note the liquid level condition in the sloptank 10 so, avoid being evacuated because of float relay 7 faults cause liquid container 5; If liquid container 5 is evacuated, then should in time draw liquid to guarantee carrying out smoothly of self-priming drawing liquid operation to liquid container 5 perfusions.
To combine the horizontal self-sucking pump of the utility model exemplary embodiment to describe its working method below.
Earlier close outlet valve 3 tight before the drawing liquid for the first time, and in liquid container 5, fill with and draw liquid.When the liquid in the sloptank 10 completely amasss to upper limit position; Float 8 in the float relay 7 floats to the H position owing to the buoyancy of water effect; This moment, float relay 7 control horizontal centrifugal pump 1 were opened; Open outlet valve 3 simultaneously, the liquid that draws in the liquid container 5 flows out and flows out via drain pipe 4, outlet valve 3, horizontal centrifugal pump liquid outlet 2 then from liquid container lower openings 5-1 under the effect of horizontal centrifugal pump 1.Because the liquid level in the liquid container 5 descends; Negative pressure appears in the tank body; Liquid in the sloptank can constantly flow in the liquid container 5 via liquid inlet pipe 6, liquid container upper opening 5-2 under action of pressure at this moment, and is constantly taken away by horizontal centrifugal pump 1 then, realizes self-priming drawing liquid operation circularly.
If the outlet conduit at the liquid outlet of horizontal centrifugal pump 2 places is shorter, in the drawing liquid operation, should note the level condition in the sloptank 10 so, avoid being evacuated because of float relay 7 faults cause liquid container 5.Just in case the situation of finding time occurs, should in liquid container 5, fill again and draw liquid.
When the liquid level in the sloptank 10 was reduced to the lower position, the float 8 in the float relay 7 was because the buoyancy of water effect also drops to the L position with its deadweight, and float relay control this moment horizontal centrifugal pump 1 is closed, and closes outlet valve 3 simultaneously, accomplishes drawing liquid work.When needs once more during drawing liquid, repeat said process and get final product.
In sum; The horizontal self-sucking pump of the utility model utilizes siphon principle, before common horizontal centrifugal pump, increases to adorn a liquid container, transform it as horizontal self-sucking pump and produces to replace Under Water Pumps; Control centrifugal priming of pump and stop through float relay is set simultaneously; Low, the consuming time weak point of reforming cost not only, and can realize self-absorption function fully, have very strong practicability and good popularization value.In addition; The utility model is simple in structure, easy to maintenance; Only need in starting the forward direction liquid container first, fill with to draw liquid, can solve the problem that the pump housing when utilizing Under Water Pumps to extract sloptank liquid damages more and maintenance difficult, guaranteed safe, continuous, stable production.
Although specifically described the horizontal self-sucking pump of the utility model with reference to the exemplary embodiment of the utility model; But those skilled in the art will be appreciated that; Under the situation of spirit that does not break away from the utility model and scope, can make various forms of changes to embodiment.
