Abstract
The invention relates to a sealless self-priming pump with a novel backwater device. The sealless self-priming pump comprises a pump body, an impeller, a pump shaft, a water adsorption chamber, a water inlet, an intermediate diaphragm, a separation chamber and a water outlet. The sealless self-priming pump is characterized in that an up-and-top through return hole is arranged at the position on the intermediate diaphragm, which is close to the pump body; the bottom of the return hole is provided with a net plate; a through slot is arranged at the position on the pump body, which is opposite to the return hole; an O-shaped sealing ring is arranged at the edge of a notch of the through slot; a movable block is embedded in the notch of the through slot; and the forward travel of the movable block is coincided with the return hole. The sealless self-priming pump is characterized in that the front end of the movable block is of a triangle shape; and the front part of the movable block is provided is provided with a limit strip. The sealless self-priming pump has the advantages that when the pump is started, in the self-priming process, the movable block is opened and after completing the self-priming, the sealless self-priming pump enters the normal operation and the diaphragm is closed, so that not only can the self-priming effect be met, but also the loss of return leakage in the operating process can be ensured to be reduced and the high efficiency effect is achieved.
Description
Technical field
The present invention relates to a kind of non-sealing self-sucking pump with novel water recovery apparatus.
Background technique
The self-absorption function of non-sealing self-sucking pump is to lean on the liquid that weighs behind the medium entering separation chamber of gas-liquid mixed to lay equal stress on to refluxed newly to mix the new gas of import; Light gas ejects; This process that constantly circulates is then accomplished the self-priming process after gas drains, get into running normally.But the return flow line of existing non-sealing self-sucking pump is to reflux through the gap between impeller 21 and stator 22 and the intermediate clapboard 23 20, and such gap is fixed, if it is fast and highly high to satisfy self-priming; The gap needs bigger so; The efficient of operation is just low so, if the gap is little, efficient is high relatively; But self-priming time is just long, and the time of self-priming and height have just had very big relation with the size of capacity of reflux here.Capacity of reflux is little, and the time is just long, and suction head is also low, and its volumetric loss that capacity of reflux is big is just big, and efficient is just low, so these two aspects are conflicting, being difficult to take into account should be efficient, again the short effect of self-priming time.
Summary of the invention
The objective of the invention is to solve in the existing technology return flow line of non-sealing self-sucking pump and be through the existing the problems referred to above that reflux of the gap between impeller and the stator and the pump housing, a kind of non-sealing self-sucking pump with novel water recovery apparatus is provided.The present invention designs a kind of non-sealing self-sucking pump with novel water recovery apparatus; Comprise the pump housing, impeller, pump shaft, suction chamber, water intake, intermediate clapboard, separation chamber, water outlet; It is characterized in that: the return port of offering a up/down perforation at the nearly pump housing place of intermediate clapboard; Be provided with a web plate in the return port bottom, on the pump housing, offer a through slot, on the notch edges of through slot, be provided with the O RunddichtringO with respect to the return port place; Be placed with a movable block in that the notch of through slot is embedded, the coincideing of movable block to front travel and return port.It is characterized in that: described web plate is a steel wire.It is characterized in that: a retractable driving device is installed in the outside of the pump housing connects movable block, it is characterized in that: the front end that movable block is is a triangle, in the movable block front portion positive stop strip is arranged.Advantage of the present invention is that movable block is opened in the self-priming process when pump startup; After getting into normal operation behind the completion self-priming dividing plate is closed; So just can both satisfy the effect of self-priming, reduce the loss that refluxes and reveal in the process that can guarantee again to move, reach effect efficiently.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is a structural representation of the present invention, and Fig. 3 is that the K of Fig. 2 is to partial schematic diagram.
Below in conjunction with accompanying drawing and construction embodiment the present invention is made detailed operation instruction.
Embodiment
Comprise the pump housing 1, impeller 2, pump shaft 3, suction chamber 4, water intake 5, intermediate clapboard 6, separation chamber 7, water outlet 8 among the figure; It is characterized in that: the return port 9 of offering a up/down perforation at the nearly pump housing place of intermediate clapboard; Be provided with a web plate 10 in the return port bottom, on the pump housing, offer a through slot 11, on the notch edges of through slot, be provided with O RunddichtringO 12 with respect to the return port place; Be placed with a movable block 13 in that the notch of through slot is embedded; Coincideing to front travel and return port of movable block, the front end that movable block is is a triangle, in the movable block front portion positive stop strip is arranged.It is characterized in that: described web plate is a steel wire.It is characterized in that: a retractable driving device is installed in the outside of the pump housing connects movable block (not drawing among the figure).
The present invention keeps impeller constant with the gap between the stator and the pump housing, does for a short time as far as possible, and opens the passage (being return port) of backflow on the intermediate clapboard between suction chamber and the separation chamber; Refill steel wire in its hole after having opened return port; The liquid that refluxes can better be scattered mix mutually with the air of suction chamber, do simultaneously one with the identical movable block of return port shape, movable block is opened in the self-priming process when pump startup; After getting into normal operation behind the completion self-priming movable block is closed; So just can both satisfy the effect of self-priming, reduce the loss that refluxes and reveal in the process that can guarantee again to move, reach effect efficiently.And the front end of movable block to be triangle can guarantee accurate positioning, guarantee excessively not pulled out at the anterior positive stop strip of movable block.
Claims (4)
1. non-sealing self-sucking pump with novel water recovery apparatus; Comprise the pump housing, impeller, pump shaft, suction chamber, water intake, intermediate clapboard, separation chamber, water outlet; It is characterized in that: the return port of offering a up/down perforation at the nearly pump housing place of intermediate clapboard; Be provided with a web plate in the return port bottom, on the pump housing, offer a through slot, on the notch edges of through slot, be provided with the O RunddichtringO with respect to the return port place; Be placed with a movable block in that the notch of through slot is embedded, the coincideing of movable block to front travel and return port.
