Problems solved by technology

Since there is a suddenly enlarged space (gas-liquid separation chamber) between the outlet of the pump volute and the outlet of the pump body, there is still a continuous backflow of water during normal operation, resulting in diffusion losses, which seriously reduces the efficiency of the pump.

Abstract

The invention relates to a high-efficiency energy-saving horizontal self-sucking pump which comprises a pump shell and a pump body, wherein the pump shell and the pump body are formed into a whole, and a flexible material sleeve is arranged on the outlet pipe of the pump body and at the outlet end of the pump shell. When the self-sucking pump is started for vacuum pumping, water can reflow through a gap between the outlet end of the pump shell and the outlet pipe of the pump body to implement a vacuum pumping starting program; when the self-sucking pump normally works, because water pressure is increased, the impulsive force generated by discharged water enables the upper part of the flexible material sleeve at the outlet end of the pump shell to be enlarged and extruded together with the outlet pipe of the pump body to generate a sealing action, and the continuous reflow of the water is blocked, thereby reducing the volume loss of the self-sucking pump and improving the water pump efficiency by 5-8 percent.

Description

technical field [0001] The invention relates to a horizontal self-priming pump. Background technique [0002] The working principle of the horizontal self-priming pump is: before the self-priming pump is started, the pump chamber is filled with water. After the pump is started, the impeller rotates at a high speed to make the water in the impeller flow channel drain out of the volute, so that the pump inlet forms a vacuum, and the water in the suction pipe Air enters the pump, mixes with the water in the pump chamber, and is discharged to the gas-liquid separation chamber on the upper part of the pump chamber through the impeller. Due to the sudden increase of the outlet area, the air and water are separated, and the separated air is discharged through the pump outlet pipe, and the separation Due to its high specific gravity, the water that comes out sinks and flows to the outer edge of the impeller through the return hole at the bottom of the pump casing, and continues to m...
