Abstract
The utility model relates to an upright type volute double suction axially split pump. A double suction pump serves as one important form of centrifugal pumps and is widely used in engineering due to the fact that the double suction pump is characterized by being high in lift, large in flow and the like. A traditional double suction pump matched with a common shell body has the shortages of being restricted in bearing capacity, insufficient in cooling and the like in practical application. In addition, the phenomenon that particles clamp a pump shaft exists. The upright type volute double suction axially split pump comprises a pump body, a pump shaft, impellers and a drive motor. The pump body comprises an outer shell. The outer shell is in a volute shape. A liquid pipeline is arranged on the outer shell. Area of a section of the liquid pipeline is enlarged gradually from a shell body connecting end towards the outer side. The impellers adopt a same-side double suction impeller structure form. The drive motor is provided with a coupler. The pump shaft is arranged on the coupler. The upright type volute double suction axially split pump is simple in structure, convenient to use and widely suitable for matching use of industries such as water drainage, fire protection, spray irrigation, water treatment and food.
Description
Technical field
The utility model relates to a kind of vertical spiral case Double entry middle-opening 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 entry middle-opening pump is provided.
For solving the problems of the technologies described above, this vertical spiral case Double entry middle-opening 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, the described pump housing is provided with at least one 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 entry middle-opening 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 entry middle-opening pump is simple in structure, easy to use, is widely used in the industries such as draining, fire-fighting, sprinkling irrigation, water treatment, food and supports the use.
Description of drawings
Below in conjunction with accompanying drawing, this vertical spiral case Double entry middle-opening pump is described further:
Fig. 1 is the cross-sectional view of this vertical spiral case Double entry middle-opening pump;
Fig. 2 is the plane structure schematic diagram of this vertical spiral case Double entry middle-opening pump.
In figure: 1 pump housing, 2 pump shafts, 3 drive motor, 4 fluid pipelines, 5 impellers, 6 coupling, 7 water lubriucated bearings, 8 cleaning hoses.
Embodiment
Mode of execution: as shown in Fig. 1-2, this vertical spiral case Double entry middle-opening pump comprises the pump housing 1, pump shaft 2, impeller and drive motor 3, and the described pump housing 1 comprises shell, and this shell is scroll casing shape, which is provided with fluid pipeline 4, these fluid pipeline 4 section area outwards increase gradually from the housing connecting end; Described impeller 5 adopts homonymy double-entry impeller structural type; Described drive motor is provided with coupling 6, and described pump shaft 2 is arranged on this coupling 6.The described pump housing 1 lower end is provided with water lubriucated bearing 7, and the pump seal mode is mechanical seal.The described pump housing is provided with at least one cleaning hose 8, and the one end is connected to the pump housing 1 outside, and the other end extends to impeller 5 and drive motor 3 arbor joints.
The utility model includes but not limited to above-mentioned mode of execution, and any product that meets the description of these claims is within all falling into protection domain of the present utility model.
