Embodiment Construction

[0017] Referring to Figs. 1-2, this example centrifugal water pump of the present invention has a cast iron impeller (4) with a coaxial water inlet (7) and an oblate whose inner cavity size matches the size of the impeller (4) Vase-shaped steel pump body (3). The "vase mouth" above the center of the pump body (3) is the radial drain (2). The pump body (3) has a coaxial water inlet (6) and a pump cover (9). The water inlet (6) corresponds to the position of the water inlet (7) of the impeller (4) and is on the same axis, and the impeller ( 4) The coaxial line is placed in the cavity of the pump body (3), so that the diameter of the center line of the drain port (2) of the pump body (3) and the corresponding section of the impeller (4) axle (5) Lines overlap. One end of the shaft (5) of the impeller (4) is axially connected to a main shaft (1) connected to the motor shaft, and the corresponding main shaft (1) of the pump body (3) is provided with a radial annular groove (10) a...

Abstract

The invention is an improved centrifugal pump, it belongs to radial flowing pump field. It is made up of main aces, pump body and the vanes in pump, the pump body and the vanes have water entrance with the same aces, and there is radial water outlet, the centre of outlet is overlapped with section radial of vane axes.

Description

technical field [0001] The invention relates to an improved centrifugal water pump, which belongs to the radial flow pump [0002] technology field. Background technique [0003] The structure of the pump body of the traditional centrifugal water pump is in the geometric shape of the Archimedes spiral, and the medium, namely water, is discharged from the tangential direction of the impeller. When the impeller is working, it is actually under the simultaneous action of two forces, namely the centrifugal force and the thrust of the blade arc slope, to repeatedly push out multiple water rings into the casing cavity (the number of water rings corresponds to the number of blades), Pascal's law tells us, The pressure applied to the closed fluid can be transmitted from the fluid to all directions according to its original size. The traditional design violates Pascal's law and the principle of force balance, resulting in low efficiency. Contents of the invention [0004] The te...
