Abstract

The invention relates to a pump body of a vortex type self-priming electric pump and a pumping method thereof, and belongs to the field of electric pumps to solve the problems that an existing vortexpump is poor in gas exhaust effect and not ideal in pumping effect. According to the technical scheme, the pump body of the vortex pump comprises a shell, an eddy cavity, a water inlet volute cavity and a gas-water separation chamber, wherein the eddy cavity, the water inlet volute cavity and the gas-water separation chamber are formed in the shell; the water inlet volute cavity and the gas-waterseparation chamber are separated by a separation cavity wall, a water filling port is formed in the top of the gas-water separation chamber, a first partition wall is arranged between a water outlet cavity and the gas-water separation chamber, one end of a first baffle is arranged on the upper portion of the first partition wall, and the other end of the first baffle transversely extends to the separation cavity wall; a notch is formed below the water filling port and used for blocking fluid, so that a part of the fluid flows back into the eddy cavity, and gas follows the other part of the fluid to enter the water outlet cavity through the notch. The invention provides a method for pumping the fluid through the pump body. Part of the fluid falls back under the blocking action of the firstbaffle, the negative pressure effect can be utilized all the time, the pumping effect of the pump body is ideal, and large lift can be obtained.

Description

technical field [0001] The invention belongs to the field of electric pumps, in particular to a pump body of a vortex type self-priming electric pump and a pumping method thereof. Background technique [0002] The existing vortex pump has a pump body, a frequency converter, a pressure tank and a motor. The pump body is provided with a water inlet and a water outlet, and the axes of the water inlet and the water outlet are on the same straight line. The electrical connection of the motor is used to control the operation of the motor. The drive shaft of the motor is connected to the impeller to drive the impeller to rotate. The frequency converter can control the opening and closing of the motor and adjust the speed of the motor. The pressure tank stabilizes the internal pressure of the pump body during the process. During use, the impeller rotates to accelerate the fluid and push it from the water inlet to the water outlet to obtain the lift. Fill the pump body with water be...
