Abstract
The invention relates to a novel structure of a self-suction horizontal-type multi-stage pump. The novel structure of the self-suction horizontal-type multi-stage pump comprises a coupling, a bearing part, a machine sealing pressing cover, a mechanical seal, a machine seal flushing pipe, a suction section, a first stage impeller, an impeller, a guide vane, a final stage guide vane, a balancing sleeve, a balance disc, a middle section, a discharge section, a balancing pipeline, a sealing box, a bearing part, an inlet connection pipe, a pipe bending component and a first stage middle section. The novel structure of the self-suction horizontal-type multi-stage pump is characterized in that a check valve is arranged inside the inlet connection pipe to prevent backflow, an air water separation chamber is formed in a first stage position of the middle section, the air water separation chamber and the discharge section are connected with an air bleeding pipe, an one-way valve is arranged inside the air bleeding pipe to prevent air of the discharge section from entering the air water separation chamber, a water outlet chamber of the discharge section is connected with a suction chamber of a suction section in a communicating mode through a backflow pipe, and a regulating valve is arranged inside the backflow pipe. The novel structure of the self-suction horizontal-type multi-stage pump has the advantages that leakage loss of the impeller is enabled to be zero, volume efficiency of a pump reaches 100%, efficiency of a single-stage single suction pump is largely improved, and a good energy-saving effect can be achieved.
Description
Technical field
The present invention relates to submersible axial flow pump and submersible mixed-flow pump field, particularly a kind of new structure of self-priming horizontal type multi-stage pump.
Background technique
Existing D type horizontal multi-stage pump structure, as Fig. 1, comprise: coupling 1, bearing part 2, machine sealed cover 3, mechanical seal 4, machine envelope cleaning hose 5, suction casing 6, first stage impeller 8, impeller 9, stator 10, final stage stator 11, balance set 12, Balance disc 13, stage casing 15, Spit Section 18, equalizing line 19, sealed letter body 20, bearing part 21, this structure has following shortcoming: 1, without self-absorption function; 2 if self-priming needs at the pump inlet pipeline, vacuum pumping device is installed, and will be joined electrical control cabinet and control; Its shortcoming pipeline is complicated, needs automatically and manually operation together complicated operation.
Summary of the invention
The present invention seeks to overcome many deficiency factors of prior art, proposed a kind of new structure of self-priming horizontal type multi-stage pump.
The present invention is achieved in that a kind of new structure of self-priming horizontal type multi-stage pump, comprise: coupling, bearing part, machine sealed cover, mechanical seal, machine envelope cleaning hose, suction casing, first stage impeller, impeller, stator, final stage stator, balance set, Balance disc, stage casing, Spit Section, equalizing line, sealed letter body, bearing part, inlet connection, winding pipe assembly, chopped-off head stage casing, it is characterized in that: be provided with a check valve in described inlet connection, to prevent refluence; Chopped-off head place in the stage casing is formed with an air-water separation chamber, and air-water separation chamber and Spit Section are connected with an exhaust tube; Be provided with an one-way valve in this exhaust tube, enter air-water separation chamber with the air that prevents the Spit Section; The water-supplying chamber of described Spit Section is connected by the suction chamber perforation of a reflow pipe and suction casing, and this reflow pipe inside is provided with a regulating valve.
Advantage of the present invention: the leakage loss that makes impeller is zero, and the volumetric efficiency of pump reaches 100%, greatly improves the efficient of whole single-stage single suction pump, plays good energy-saving effect.
Description of drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present invention.
Below in conjunction with drawings and Examples, the present invention is elaborated.
Embodiment
In figure, a kind of new structure of self-priming horizontal type multi-stage pump, comprise: coupling, bearing part, machine sealed cover, mechanical seal, machine envelope cleaning hose, suction casing, first stage impeller, impeller, stator, final stage stator, balance set, Balance disc, stage casing, Spit Section, equalizing line, sealed letter body, bearing part, inlet connection, winding pipe assembly, chopped-off head stage casing, it is characterized in that: be provided with a check valve in described inlet connection, to prevent refluence; Chopped-off head place in the stage casing is formed with an air-water separation chamber, and air-water separation chamber and Spit Section are connected with an exhaust tube; Be provided with an one-way valve in this exhaust tube, enter air-water separation chamber with the air that prevents the Spit Section; The water-supplying chamber of described Spit Section is connected by the suction chamber perforation of a reflow pipe and suction casing, and this reflow pipe inside is provided with a regulating valve.
During use, the pump housing is deposited certain water gaging, and after pump startup, due to the turning effort of impeller, the empty G﹠W of suction line mixes fully, and air is discharged to air-water separation chamber and carries out the gas separation.The gas on air-water separation chamber top is discharged to outlet pipe by bleed line, the current direction subordinate impeller of bottom, finally flow to the Spit Section pumping chamber, water is again by the import of reflow pipe directive first stage impeller, again the residual gas with suction casing mixes, and carries out sufficient gas and mix in first stage impeller, until the gas of pump and inlet pipeline is all drained, complete self-priming, and normal pumping.Bleed line is because pump Spit Section pressure is high, one-way valve autoshutdown bleed line.And reflow pipe can pass through the automatic or manual throttle down, realizes the closing volume pipeline.
Below only expressed embodiments of the present invention, it describes comparatively concrete and detailed, but can not therefore be construed as limiting the scope of the patent.Should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
