The utility model discloses a pump body outside is provided with the heat preservation and presss from both sides the cover, and the heat preservation scope is big, is favorable to carrying the medium that needs keep the uniform temperature, can be used to the heat pump and prevents that the medium from solidifying.
Description
Technical Field
The utility model relates to an axial-flow pump field, in particular to novel jacket formula axial-flow pump.
Background
The axial-flow pump is a general machine with wide application, has huge domestic requirements, and is mainly suitable for occasions with low lift and large flow, such as irrigation, waterlogging drainage, dock drainage and water level adjustment of canal locks, or used as a large-scale circulating water pump of a power plant. However, when the existing axial flow pump transports a medium with a temperature requirement, the heat preservation performance is poor, the medium is easily solidified, so that the working efficiency of the axial flow pump is influenced, and even the axial flow pump is easily blocked. It is therefore desirable to provide an axial flow pump that provides thermal insulation.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the technical problem and providing a novel jacketed axial-flow pump.
The purpose of the utility model is realized like this: a novel jacket type axial-flow pump comprises a bearing box body, a pump body, a shaft and an impeller part; the right side of the pump body is provided with a bearing box body, the shaft passes through the bearing box body and the pump body, and the impeller part is arranged in the pump body and matched with the shaft; the method is characterized in that: the left side of the pump body is provided with a pump inlet, and the upper part of the pump body is provided with a pump outlet; the pump body on be provided with the heat preservation and press from both sides the cover, heat preservation press from both sides the cover below be provided with the import, the top is provided with the export, the import other be provided with the drain mouth.
The inlet and the outlet are respectively connected with an external steam pipeline through flanges, and the exhaust port is sealed through a bolt structure.
The heat-insulating jacket is welded by a forming elbow, and the seam of the jacket adopts a full-welding structure.
The utility model discloses a pump body outside is provided with the heat preservation and presss from both sides the cover, and the heat preservation scope is big, is favorable to carrying the medium that needs keep the uniform temperature, can be used to the heat pump and prevents that the medium from solidifying.

in the figure: 1. a pump body; 2. a heat-preserving jacket; 3. an outlet; 4. a bearing housing; 5. a shaft; 6. a discharge port; 7. an inlet; 8. an impeller member; 9. a pump inlet; 10. the pump outlet.
Detailed Description
The present invention will be further described with reference to the accompanying drawings, which are not intended as limitations of the present invention: a novel jacket type axial-flow pump comprises a bearing box body 4, a pump body 1, a shaft 5 and an impeller part 8; the right side of the pump body 1 is provided with a bearing box body 4, the shaft 5 penetrates through the bearing box body 4 and the pump body 1, and the impeller part 8 is arranged in the pump body 1 and matched with the shaft 5; the method is characterized in that: the left side of the pump body 1 is provided with a pump inlet 9, and the upper part of the pump body is provided with a pump outlet 10; the pump body 1 on be provided with heat preservation and press from both sides the cover 2, heat preservation press from both sides 2 below be provided with import 7, the top is provided with export 3, import 7 other be provided with the drain mouth 6.
The inlet 7 and the outlet 3 are respectively connected with an external steam pipeline through flanges, and the exhaust port 6 is sealed through a bolt structure. The heat-insulating jacket 2 is welded by a forming elbow, and the seam of the jacket 2 adopts a full-welding structure.
The outer side of the pump body is provided with the heat-insulating jacket, so that the heat-insulating range is wide, the medium which needs to be kept at a certain temperature can be conveyed, and the pump can be used for warming a pump and preventing the medium from being solidified; two modes can be adopted for heat preservation, steam is used for preserving heat at a high inlet and a low inlet, and hot water is used for preserving heat at a low inlet and a high outlet; the heat-insulating jacket is welded by adopting a forming elbow, the structure is simple and reliable, and the heat-insulating effect is ideal; the seam of the jacket adopts an all-welded structure, so that the leakage is not easy to occur and the pressure resistance is firm; the inlet and the outlet of the heat-insulating jacket are connected by flanges, and a drain port is arranged at a low point, so that liquid drainage and cleaning are facilitated; and a plurality of reinforcing rib plates are arranged on the jacket, and a plurality of small holes are formed in the rib plates, so that the heat-insulating medium can flow in the jacket.
The above embodiments of the present invention are only examples for clearly illustrating the present invention, but not for limiting the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
