Description
Technical Field
The utility model relates to a water pump design field especially relates to the structure of intaking based on high-efficient single-stage double suction horizontal split pump is used.
Background
In the fluid field, a single-stage double-suction horizontal split pump is the most widely used water pump. The water inlet structure of the water pump influences the efficiency and the cavitation performance of the water pump, and the existing water inlet chamber divides inlet water into two branches to flow into the double-suction impeller directly by using the outer wall of the water pressing chamber.
The flow speed of the fluid flowing in the water suction chamber is blocked by the water pumping chamber, the fluid is divided into two branches by the stagnation area, the fluid flows around the outer wall of the water pumping chamber, certain energy is consumed by the flow around, and therefore the flow speed and the pressure of the fluid are reduced, and shape resistance is generated. The cross section of the existing water pumping chamber has a rectangular shape, a trapezoidal shape, a circular shape and the like, and the streaming of the water pumping chamber in any shape can generate great local hydraulic loss, so that the flowing efficiency of fluid is reduced.
The present invention has been made in view of such circumstances.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a water inlet structure based on high-efficient single-stage double suction horizontal split pump is used, effectively solve above-mentioned technical problem.
For effectively solving the technical problem, the utility model discloses the technical scheme who takes as follows:
the water inlet structure based on the application of the high-efficiency single-stage double-suction horizontal split pump comprises a structure main body, wherein a pumping chamber and a water suction chamber located below the pumping chamber are arranged in the structure main body, and the section of the pumping chamber is connected with a streamline flow guide cone.
Particularly, the streamline-shaped flow guide cone is integrally connected with the wall of the pumping chamber, the flow guide cone is hollow and is triangular, and the cone head faces the direction of the water suction chamber, so that fluid flows around to two sides of the flow guide cone.
Particularly, the cone head of the streamline flow guide cone is in a circular arc shape.
In particular, the cross section of the pumping chamber is one of a rectangle, a trapezoid or a circle.
The utility model has the advantages that: the utility model provides a structure of intaking based on high-efficient single-stage double suction level well pump is used under the condition that does not change pressurized-water chamber cross sectional shape, at the preceding streamlined water conservancy diversion awl that increases of pressurized-water chamber, make the dead zone reduce to nearly a point, let the fluid high efficiency around flowing to water conservancy diversion awl both sides, water conservancy diversion awl both sides design the streamline type, make the fluid not take place the separation, improve fluid flow efficiency, great reduction energy loss improves the efficiency and the cavitation performance of pump.
