Abstract
The utility model relates to a centrifugal pump, the main flow passage component of the centrifugal pump comprises a spiral pressure chamber and an impeller. The spiral chamber of the pump is separated from the pump body and is sleeved and arranged in the shell of a cylinder pump body. As the spiral pressure chamber and the pump body are first separated form each other and then assembled together, the manufacture of the spiral pressure chamber and the pump body is simple and different materials can be adopted, the beautiful pump body shell and the spiral pressure chamber with smooth channel can be produced, thus improving the efficiency of the water pump and reducing the manufacturing cost of the water pump.
Description
Technical field
The utility model relates to a kind of Centrifugal water pump, especially a kind of centrifugal pump that is made of main flow passage components spirality pumping chamber and impeller together.
Background technique
Traditional one-stage centrifugal water pump, be by driven by motor, motor shaft stretches in the pump housing with movement parts such as impeller and connects and composes, the spirality pumping chamber forms when being cast by the pump housing, runs up by motor, and water enters impeller from pump housing water intake, obtain energy through impeller, pass through the spirality pumping chamber again, flow out from water outlet at last, reach the purpose of drawing water.The pump housing of this class water pump and spirality pumping chamber are that the pump housing runner that casting is come out is general more coarse, be difficult to reach designing requirement, so the efficient of water pump does not firmly firmly reach designing requirement with the moulding of casting technique integrally casting.In addition, adopt the water pump of Foundry Production, owing to be subjected to the restriction of casting technique, general pump wall is all thicker, and material requested is many, and product cost has been difficult to significantly descend.
Summary of the invention
The purpose of this utility model is to improve the traditional water pump structure, provides a kind of and has that technology is simple, easy processing, cost of production is low, pump efficiency is high novel centrifugal water pump.
The scheme that the utility model purpose realizes is: the spirality pumping chamber and the pump housing of prior art middle pump body are separated, and the spirality pumping chamber is sleeved in the pump housing shell.
The utility model is because spirality pumping chamber and pump housing shell are after independently being shaped respectively, fit together again, so that manufacturing separately is all very simple, and can adopt different made separately, thereby can produce the pump housing shell and the smooth spirality pumping chamber of runner of beautiful shape, can satisfy the waterpower designing requirement, so the efficient of water pump is all higher than traditional all iron pump and existing punching press pump.
The utility model structure is applicable to horizontal, vertical single stage centrifugal water pump.
Description of drawings
Fig. 1 is a sectional structure chart of the present utility model.
Fig. 2 is the sectional view of the utility model spirality pumping chamber.
Fig. 3 is the plan view of Fig. 2 spirality pumping chamber.
Embodiment
As shown in Figure 1, this embodiment's water pump mainly is made up of following component: intake pipe 1, cylindrical shape pump housing shell 2, spirality pumping chamber 3, impeller 4, outlet pipe 5, motor connection seat 6, Sealing 7, motor 8 etc.Motor connection seat 6 links into an integrated entity with motor 8, and motor shaft 9 stretches in the pump housing, and order is equipped with Sealing 7 and impeller 4 thereon, and impeller 4 is linked together by key and motor shaft 9, and uses nut impeller 4 axial restraints at the end of motor shaft 9.Intake pipe 1 and outlet pipe 5 are welded on the position of the entery and delivery port of cylindrical shape pump housing shell respectively, cooperating of the interior circle of spirality pumping chamber 3 by cylindrical and cylindrical shape pump housing shell 2, after being sleeved in the cylindrical shape pump housing shell 2, be fixed by bolts to again on the motor connection seat 6.
During work, motor 8 high speed rotating, impeller 4 high speed rotating, make the water that enters from intake pipe 1 obtain energy, become press water, after press water comes out from impeller 4, collect by spirality pumping chamber 3, eliminate liquid from rotatablely moving that impeller 4 flows out, and make speed can convert pressure energy to.The water that has the pressure energy at last flows out from outlet pipe 5, reaches the purpose of drawing water.
Claims (2)
1, a kind of novel centrifugal water pump, the pump housing and motor (8) fuse, motor shaft (9) stretches into and connects impeller movement parts such as (4) in the pump housing, the pump housing comprises spirality pumping chamber (3), intake pipe (1) and outlet pipe (5), it is characterized in that spirality pumping chamber (3) separates with the pump housing, spirality pumping chamber (3) is sleeved in the pump housing shell (2).
