In figure: buoyancy suction nozzle 1, filter screen 2, suction pipe 3, takes out assembly 4 on liquid, nozzle 5, trunnion 6, liquid level Detecting element 7, spout 8, bleed valve 9, liquid return pipe 10, there is press liquid inlet duct 11, valve 12, pump 13, pressure detecting element 14, valve 15, valve 16, one-way valve 17, on liquid, picking device 18, liquid container 19.
Embodiment:
Specific embodiments of the invention are described further in conjunction with Figure of description, according to the high priming stroke self priming pump of Figure of description 1, before starting for the first time, first close outer pipe valve (15), inlet duct valve (16) and have the upper valve (12) of press liquid inlet duct (11), by spout (8), by taking out assembly (4) on pump (13) and liquid, fill with after liquid, start pump (13), until pressure detecting element (14) detect pressure normal after, opened manually or automatically the upper valve (12) of press liquid inlet duct (11), the press liquid that has by pump (13) output is taken out assembly (4) by having press liquid inlet duct (11) and valve (12) to enter on liquid, when through nozzle (5), injection enters trunnion (6), in trunnion (6) ingress, produce negative pressure, thereby gas or the liquid on suction pipe (3) and liquid, taken out in assembly (4) are sucked to trunnion (6), and with there being press liquid to discharge together trunnion (6), when gas-liquid mixture enters into while taking out assembly (4) top on liquid, gas is discharged by outlet valve (9), liquid is back to after the interior pressurization of pump (13) by liquid return pipe (10), continue to enter and on liquid, take out the body of bleeding on assembly (4).When taking out gas in assembly (4) liquid being detected by basic emptying liquid level Detecting element (7) on suction pipe (3) and liquid, close manually or automatically bleed valve (9), and open manually or automatically successively inlet duct valve (16), outer pipe valve (15) and closed the upper valve (12) of press liquid inlet duct (11).Now rely on the suction capacity of pump (13) just liquid below can be drawn in pump (13) by filter screen (2), suction pipe (3) and valve (16), after pump (13) pressurization, from outer pipe, discharge.If the suction journey of pump (13) self is not enough to liquid below to suct, can not open inlet duct valve (16) and not close the upper valve (12) of press liquid inlet duct (11), the having a press liquid part to continue to flow into take out assembly (4) on liquid of now pump (13) output sucts liquid, to meet the normal work of pump (13).
During termination of pumping (13), should close successively outer pipe valve (15) and inlet duct valve (16), then termination of pumping (13).Now on pump (13) and liquid, take out in assembly (4) and have liquid, again during priming pump (13) without fluid injection, accomplish a fluid injection, lifelong self-priming.
In needs are removed storage tank all during liquid, along with the decline buoyancy suction nozzle (1) of liquid level also can decline, make buoyancy suction nozzle (1) and tank bottom gap more and more less, now should open the upper valve (12) of press liquid inlet duct (11), and turn down gradually outer pipe valve (15), reduce the outflow of liquid, to guarantee to have in pump (13), on enough liquid supply liquid, take out assembly (4) and take out on continuously, thereby liquid is all siphoned away.
Specific implementation method and Fig. 1 of Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6 are basic identical, are provided with the one-way valve (17) that prevents liquid and drop on the suction pipe (3) of Fig. 2, Fig. 4 and Fig. 5.
Fig. 2 is provided from smoking liquid to pump (13) by liquid container (19), and when pump (13) is normally worked, liquid below first sucts by taking out assembly (4) on liquid, thereby improves the suction journey of pump (13).
Fig. 3 is that the outlet of taking out assembly (4) on liquid is directly connected with pump (13) entrance, while taking out assembly (4) on liquid process liquid after pump (13) runs well, can increase loss of pressure head.
Fig. 6, for there is no for the first time fluid injection condition, sucts liquid by picking device on liquid (18) and completes fluid injection for the first time, and spout (8) can be used as the suction port of picking device on liquid (18).
Finally, it is also to be noted that above what enumerate is only several specific embodiment of the present invention, obviously the invention is not restricted to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from content disclosed by the invention, all should think protection scope of the present invention.
