Abstract
The utility model belongs to the technical field of water pumps, in particular to a seawater self sucking pump, which is characterized in that the left upper side of a water storage chamber body formed by a lower body of the seawater self sucking pump is communicated with an air-water separating chamber, the water storage chamber is communicated with the lower side of an impeller chamber via a water return hole arranged between the water storage chamber and the lower side of the impeller chamber, the water storage chamber is connected with a water inlet pipe on the right side of the impeller chamber, a water inlet of the water inlet pipe is located at a position higher than that of an impeller, the impeller chamber is further equipped with a water outlet pipe, and the upper end of the air-water separating chamber is equipped with a flow guide opening connected with an exhaust valve. Therefore, the seawater self sucking pump has the advantages of simple structure, small volume, low cost and short self sucking time and capability of reducing cavitation erosion of pumps.
Description
Technical field: the utility model belongs to the pump technology field, is 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, not safety check. its shortcoming one is that volume is big, and is 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 utility model provides a kind of simple in structure, and volume is little, and cost is low, the seawater self-priming pump that self-priming time is short.
The technical solution of the utility model 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 utility model;
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.
