Abstract
The present invention relates to a minitype centrifugal self-sucking water pump case which is composed by a universal minitype centrifugal water pump spiral casing provided with a inlet port, a storage box situated at the top and integrated with the spiral casing, a outfall port from the spiral casing to the storage box, a refluence port from the storage box to the spiral casing, a outlet port on one end of the storage box and another fabrication hole or outlet port located on the top of the storage box. When the water pump stops work, water inside the storage box refluxes and fills full of the spiral casing, blade wheel and inlet port; when water pump startup, the blade wheel rotating in quick speed discharges this portion of water, and then sucks water from the inlet port to add self-sucking function to the water pump without filling the water pump with water full before startup each time, which can be broadly applied on occasions that need small pressurized water like households and hotels.
Description
Affiliated field: the present invention relates to a kind of small-sized centrifuge self-primping water pump housing.
Background technique: the small-sized Centrifugal water pump that is used for occasions such as family on the market, generally all belong to the single-stage volute pump, power is greatly about about 100W, want earlier before the work fills with water in the pump, could work then, all do not possess self-absorption function, thereby use occasion is subjected to certain limitation, can not satisfies actual requirement with self-absorption function.
Goal of the invention: the objective of the invention is to a kind of pump case of small size single stage spiral case centrifugal water pump design, so that this small-sized centrifugal water pump need not fills with water just can be automatically the no pressure flow suction that is in lower position and to its supercharging before each work with self-absorption function.
Summary of the invention: a kind of small-sized centrifuge self-primping water pump housing, be on former small-sized Centrifugal water pump spiral case, increase a water storage case that is connected as a single entity with it at its top, the drain opening of this water storage case in the spiral case of pump communicates with spiral case, and be provided with one at the spiral case top opposite side relative and lead to return port in the spiral case by water storage case with drain opening, end at water storage case is provided with a water outlet, and is provided with another water outlet composition in the positive corresponding part of return port at the tip position of water storage case.The volume of described water storage case should be greater than formed volume in water pump spiral case and the impeller cavity.So that after water pump quits work, the water in the water storage case refluxed in the spiral case impeller be full of pump and water intake, when pump is worked once more, because the impeller of quick rotation flows to impeller outer edge with this part liquid earlier under centrifugal action, impeller makes water pump have self-absorption function from the water intake suction more simultaneously; Described top water outlet, when pump case adopts metal casting technique to make, the auxiliary hole when at first making as return port, it can be sealed after finishing manufacturing, also can be reserved as the top water outlet, choose one wantonly with the water outlet of water storage case one end according to demand during use, or two be continued to employ simultaneously.Described centrifugal self-priming pump shell can be selected cast steel, cast copper, cast aluminium, cast copper aluminium, cast aluminium magnesium, casting zinc-copper, cast aluminium zinc, casting stainless steel for use, through the machining manufacturing.
When adopting engineering plastics to make with injection moulding process, according to the Shooting Technique characteristics, it is three manufacturings that small-sized centrifugal self-priming pump case is answered split, the one mold joint for the suitable position by the water storage case on pump head top be divided into the upper body and with pump case be the lower body of one, the top water outlet links to each other with the upper body, and the end face water outlet can also can link to each other with lower body with the upper body, also can only keep one of them water outlet, after the split injection moulding, with adding the unification that is linked and packed of sealing gasket bolt; Its two be by the stop portion of the spiral case end of pump case the seam part that hinders demoulding along around cut, form a garden type ring, after the molding and forming it is reinstalled the original place.
Beneficial effect: this shows that the present invention can make small-sized centrifugal water pump have self-absorption function, and simple in structure, easily manufactured, cost is low, can be widely used in the productive life, and is practical and convenient.
