Abstract
The utility model relates to a vertical type volute double suction pipeline pump. As an important form of a centrifugal pump, a double suction pump is widely applied in engineering due to the advantages of high lift, large quantity and the like. Traditional double suction pump has defects of limited bearing capacity, insufficient cooling and the like in coordination with ordinary shell in practical application, and besides, the phenomenon of particles blocking a pump shaft also exists. The vertical type volute double suction pipeline pump comprises a pump body, the pump shaft, an impeller and a drive motor. The pump body comprises a shell which is in a volute shape, a fluid pipeline is arranged above the pump body, sectional areas of the fluid pipeline gradually increases outwards from a shell connecting end. The vane wheel is in a same side and double suction vane wheel structural form. A coupler is arranged on the drive motor. The pump shaft is arranged on the coupler. The vertical type volute double suction pipeline pump has the advantages that structure is simple, use is convenient, and the vertical type volute double suction pipeline pump can be widely applied to industries of dewatering, fire control, sprinkling irrigation, water treatment, food and the like for supporting use.
Description
Technical field
The utility model relates to a kind of vertical spiral case double suction pipeline mounted pump.
Background technique
Double suction pump, is used widely in engineering because it has the characteristics such as lift is high, flow is large as a kind of important form of centrifugal pump.The traditional double sucking pump coordinates common housing to have in actual applications that bearing capacity is limited, the cooling deficiency such as insufficient, also exists in addition particle to kill the phenomenon of pump shaft.
The model utility content
The technical problems to be solved in the utility model is the defects that how to overcome prior art, and a kind of vertical spiral case double suction pipeline mounted pump is provided.
For solving the problems of the technologies described above, this vertical spiral case double suction pipeline mounted pump comprises the pump housing, pump shaft, impeller and drive motor, and the described pump housing comprises shell, and this shell is scroll casing shape, which is provided with fluid pipeline, this fluid pipeline section area outwards increases gradually from the housing connecting end; Described impeller adopts homonymy double-entry impeller structural type; Described drive motor is provided with coupling, and described pump shaft is arranged on this coupling.
As optimization, described pump housing lower end is provided with water lubriucated bearing, and its sealing means is packing seal or mechanical seal.
As optimization, establishing at least one on the described pump housing has cleaning hose, and the one end is connected to the pump housing outside, and the other end extends to impeller and drive motor arbor joint.
Advantage and the good effect of this vertical spiral case double suction pipeline mounted pump are: import and export all are positioned at the pump housing, can not safeguard rotor portion in the detaching pipelines situation.The scroll casing type pump housing is even to guarantee rate of flow of fluid, and double-entry impeller adopts precision casting process, and frictional loss is little, and efficient is high, lower end water lubrication sliding bearing structure, and bearing capacity is large.From pump housing zone of high pressure backflow part medium to lower bearing, utilize the spirality guiding gutter of lower bearing endoporus can guarantee cooling fully, and prevent that effectively particle etc. from killing pump shaft.
This vertical spiral case double suction pipeline pump structure is simple, easy to use, is widely used in the industries such as draining, fire-fighting, sprinkling irrigation, water treatment, food and supports the use.
