Description
Technical field
This utility model is related to a kind of centrifugal pump, especially relates to a kind of structure centrifugal pump simple, easy to use.
Background technology
At present, centrifugal pump（centrifugal pump）It is a kind of conventional water pump；When centrifugal pump refers to rotate by impeller
The pump to convey liquid for the centrifugal force producing；Centrifugal pump is to make water centrifugal motion occur come work, water using impeller rotation
Pump it is necessary to make to be full of water in pump case and suction hose, then starts motor before activation, makes pump shaft impeller and water do rotation at a high speed
Transhipment is dynamic, and water occurs centrifugal motion, is thrown toward impeller outer edge, and the runner through volute pump case flows into the pressure pipe road of water pump.But,
Conventional centrifugal pump is as shown in figure 4, its complex structure, assembly difficulty are larger, and during use, all parts cooperation easily goes out
Show problem and affect its service life, increased use cost.
Content of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of structure centrifugal pump simple, easy to use.
The purpose of this utility model is realized in：
A kind of centrifugal pump, described centrifugal pump includes spiral case, rotating shaft and connecting plate, and described spiral case and connecting plate constitute a chamber
It is provided with rotating shaft in the cavity that body, described spiral case and connecting plate are constituted, rotating shaft is provided with two blades, the side of described spiral case
Planar central is provided with water inlet, and the outer circumferential walls of described spiral case are provided with outlet, described water inlet and outlet all with
The cavity that spiral case is constituted with connecting plate is connected.
A kind of centrifugal pump of this utility model, described connecting plate is fixedly connected on the engine housing of electromotor, electromotor
Bent axle be connected through connecting plate with rotating shaft.
A kind of centrifugal pump of this utility model, described water inlet connects by the road to water source, and line end be provided with unidirectional
Valve.
Compared with prior art, the beneficial effects of the utility model are：
This utility model structure is simple, easy to use, and the centrifugal pump of routine needs in spiral case overcoat crust body, from
And lead to its complex structure；Meanwhile, this utility model paddle blade structure is simple, and setting is more reasonable；Two panels oar is installed on rotating shaft
Impeller structure；And blade is installed on the chassis that needs of the centrifugal pump of routine, thus not only increased difficulty of processing, and the later stage is more
Changing maintenance inconvenience, thus increased its use cost, being unfavorable for that it is promoted the use of.

Specific embodiment
Referring to Fig. 1 ~ 3, a kind of centrifugal pump that this utility model is related to, described centrifugal pump includes spiral case 1, rotating shaft 2 and connects
Fishplate bar 3, described spiral case 1 and connecting plate 3 constitute a cavity, are provided with rotating shaft 2 in the cavity of described spiral case 1 and connecting plate 3 composition,
Two blades 2.1 are provided with rotating shaft 2, the side plane of described spiral case 1 is provided centrally with water inlet 1.1, the circle of described spiral case 1
Outlet 1.2, described water inlet 1.1 and outlet 1.2 cavity all with spiral case 1 and connecting plate 3 composition are provided with all outer walls
It is connected；
Described connecting plate 3 is fixedly connected on the engine housing 4 of electromotor, the bent axle of electromotor pass through connecting plate 3 with
Rotating shaft 2 is connected；
Further, described water inlet 1.1 connects by the road to water source, and line end is provided with check valve, so that
Full water must be filled using in pipeline former in the front cavity that spiral case 1 and connecting plate 3 can be constituted；
In addition：It should be noted that above-mentioned specific embodiment is only a prioritization scheme of this patent, the skill of this area
Any change or improvement that art personnel are done according to above-mentioned design, all within the protection domain of this patent.
