Abstract

The utility model relates to a pressurized water chamber structure of fluid machinery, in particular to a spiral pressurized water chamber structure for a welded pump, which comprises a pressurized water chamber, a connecting plate and a pump outlet water pipe. The spiral pressurized water chamber structure is characterized in that a spiral pressurized water chamber partition plate is arranged in the pressurized water chamber, the tail end of the spiral pressurized water chamber partition plate is smoothly connected with the pump outlet water pipe by the aid of the arc-shaped connecting plate, and the initial end of the spiral pressurized water chamber partition plate and the pressurized water chamber form a spiral channel with a cross section increased gradually on the lower side of the pump outlet water pipe. The pressurized water chamber structure has the advantages that the areas of sections in the pressurized water chamber are increased evenly towards an outlet along a turning direction, average speeds in the areas of the sections are equal, hydraulic loss is decreased, the efficiency of the pump is increased, axial force is also changed to be extremely small, vibration of the pump is decreased, and stability of the pump in operation is improved. Simultaneously, the problem of difficulty in processing and manufacturing a spiral pressurized water chamber for a welded pump is solved.

Description

A kind of spirality pumping chamber structure that is used to weld the pump housing
Technical field
The utility model relates to a kind of pumping chamber structure of fluid machinery, particularly a kind of spirality pumping chamber structure that is used to weld the pump housing.
Background technique
The existing welding pump housing, for the consideration of welding manufacturing process simplicity, what pump housing pumping chamber partly adopted is annular pumping chamber structure.The characteristics of this pumping chamber are symmetrical configuration, make simple, but owing to be loop configuration, each cross-sectional area of pumping chamber equates that the flow velocity of liquid increases gradually to Way out, with the liquid that flows out from impeller collision mutually takes place, not only hydraulic loss is very big, even under design conditions, move, also can produce bigger radial force, vibration and noise ratio are bigger.
Summary of the invention
The purpose of this utility model be solve that the existing efficient that each cross-sectional area of welding pump housing pumping chamber welding pump housing annular delivery chamber equates in the prior art is low, noise and vibrate big problem.The utility model design is a kind of spirality pumping chamber structure that is used to weld the pump housing, comprise pumping chamber, connecting plate, water pump outlet pipe, it is characterized in that: one section spiral pumping chamber dividing plate is arranged in pumping chamber, spiral pumping chamber dividing plate end is linked to each other with the pump discharge water pipe is smooth by one section arc connecting plate, and the head end of spiral pumping chamber dividing plate is avris and spirality channel that cross section is cumulative of pumping chamber formation under the pump discharge water pipe.The area that the utility model has the advantages that each section in the pumping chamber by rotation direction to the ascending even variation of outlet, mean velocity in each cross-sectional area equates, not only hydraulic loss reduces, improve the efficient of pump, and axial force also can become very little, reduced the vibration of pump, the stationarity when having improved pump operation, simultaneously, also solved the problem of welding pump housing screw type pumping chamber manufacturing difficulty.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Accompanying drawing 1 is the belt pumping chamber structural representation of the existing welding pump housing, and Fig. 2 is the plan view of Fig. 1.
Accompanying drawing 3 is the spirality pumping chamber structural representation of this practicality welding pump housing, and Fig. 4 is the plan view of Fig. 3.
Embodiment
Comprise pumping chamber 1, connecting plate 2, water pump outlet pipe 3 among the figure, it is characterized in that: one section spiral pumping chamber dividing plate 4 is arranged in pumping chamber, spiral pumping chamber dividing plate end is linked to each other with the pump discharge water pipe is smooth by the connecting plate 2 of one section arc, and the head end of spiral pumping chamber dividing plate is avris and spirality channel that cross section is cumulative of pumping chamber formation under the pump discharge water pipe.Because the area of each section is pressed rotation direction to the ascending even variation of outlet in the pumping chamber, mean velocity in each cross-sectional area equates, during operation not only hydraulic loss reduce, and axial force also can become very little, improved the efficient and the traveling comfort of pump.This welding method is simple, has solved the problem of welding pump housing screw type pumping chamber manufacturing difficulty.
