Abstract

The invention relates to a seawater self-sucking pump belonging to the technical field of water pumps. The seawater self-sucking pump is characterized in that the upper left side of a cavity with a lower body forming a water storage chamber is communicated with a gas-water separation chamber; the water storage chamber is communicated with a water return hole arranged between the water storage chamber and the lower side of an impeller chamber; the right side of the impeller chamber is connected with a water inlet pipe; a water inlet of the water inlet pipe is positioned on a position higher than an impeller; the impeller chamber is also provided with a water outlet pipe; and the upper end of the gas-water separation chamber is provided with a drainage port connected with an exhaust valve. Thus the invention has the advantages of simple structure, small size, low cost, reduced gas etching of the seawater self-sucking pump and short self-sucking time.

Description

The seawater self-priming pump
Technical field: the invention belongs to the pump technology field, be specifically related to a kind of seawater self-priming pump.
Technical background: the water chamber of existing self-priming pump, blade wheel chamber and water intake all are splicing constructions, and the water inlet caliber is little, and its shortcoming one of safety check is not that volume is big, and be complicated on the mounting structure, maintain and replace inconvenience, cost height; The 2nd, for a long time need not, water easily drains automatically, each work need add water again, self-priming time is long, pipe resistance is big in the work, cavitation erosion increase, inefficient shortcoming.
Summary of the invention: the purpose of this invention is to provide a kind of simple in structurely, volume is little, and cost is low, the seawater self-priming pump that self-priming time is short.
Technological scheme of the present invention is: a kind of seawater self-priming pump, axle, axle one end of establishing bearings in bearing support are provided with impeller and are positioned at blade wheel chamber, establish dividing plate between blade wheel chamber and the bearing support, be provided with seal ring between dividing plate and the lower body, axle between dividing plate and the impeller is provided with water seal, bearing support is fixed in lower body one side, it is characterized in that: the upper left side that lower body constitutes the water chamber cavity is communicated with air-water separation chamber; Establishing backwater hole between water chamber and the blade wheel chamber downside is communicated with; Link to each other with intake pipe on the blade wheel chamber right side, the water intake of intake pipe is positioned at and is higher than on the impeller present position; Also be provided with outlet pipe in the blade wheel chamber; The air-water separation chamber upper end is provided with draining hole and outlet valve joins.
Owing to adopt technique scheme, water chamber and air-water separation chamber have been increased, intake pipe directly links to each other with blade wheel chamber, and water intake is higher than impeller face, need not splicing, after the water pump stall, there is a certain amount of water in the pump housing blade wheel chamber, starts the back because the impeller turning effort once more, the empty G﹠W of suction line fully mixes, be discharged in the air-water separation chamber through draining hole, water chamber and overflow by outlet valve, the water of bottom turns back to blade wheel chamber by water chamber, backwater hole again, thereby has simple in structure, volume is little, cost is low, can reduce the cavitation erosion of pump, the advantage that self-priming time is short.
Description of drawings: the new technological scheme of this practicality is described in further details below in conjunction with accompanying drawing and concrete enforcement.
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the plan view of Fig. 1.
Embodiment: with reference to figure 1 and Fig. 2, a kind of seawater self-priming pump, axle 5, axle 5 one ends of establishing bearings in bearing support 4 are provided with impeller 2 and are positioned at blade wheel chamber 7, establish dividing plate 3 between blade wheel chamber 7 and the bearing support 4, be provided with seal ring 13 between dividing plate 3 and the lower body, axle 5 between dividing plate 3 and the impeller is provided with water seal 14, and bearing support 4 is fixed in lower body 1 one sides, and the upper left side that lower body 1 constitutes water chamber 8 cavitys is communicated with air-water separation chamber 9; Establishing backwater hole 12 between water chamber 8 and blade wheel chamber 7 downsides is communicated with; Link to each other with intake pipe on blade wheel chamber 7 right sides, the water intake 10 of intake pipe is positioned at and is higher than on impeller 2 present positions; Also be provided with outlet pipe 16 in the blade wheel chamber 7; Air-water separation chamber 9 upper ends are provided with draining hole 11 and join with outlet valve 15.
