Description
Technical Field
The invention relates to the field of power-assisted pump bodies, in particular to a customized power-assisted pump body driving system.
Background
Electric pumps are commonly used in various fields of application. Generally, an electric pump, i.e. a pump driven electrically, is composed of a pump body, a water raising pipe, a pump seat, a submersible motor (including a cable), a starting protection device and the like. The pump body is a working part of the submersible pump and consists of parts such as a water inlet pipe, a guide shell, a check valve, a pump shaft, an impeller and the like, and the impeller is fixed on the shaft in two modes.
The working principle of the electric pump is as follows: the impeller is arranged in the pump shell and is fastened on the pump shaft, and the pump shaft is directly driven by the motor. The center of the pump shell is provided with a liquid suction pipe. The liquid enters the pump through the bottom valve and the suction pipe. The liquid discharge port on the pump housing is connected to a discharge pipe. Before the pump is started, the pump shell is filled with the conveyed liquid; after starting, the impeller is driven by the shaft to rotate at high speed, and the liquid between the blades must also rotate along with the impeller. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and obtains energy, and the liquid leaves the outer edge of the impeller at high speed and enters the volute pump shell. In the volute, the liquid is decelerated due to the gradual expansion of the flow passage, part of kinetic energy is converted into static pressure energy, and finally the static pressure energy flows into a discharge pipeline at higher pressure and is sent to a required place. When the liquid flows from the center of the impeller to the outer edge, a certain vacuum is formed in the center of the impeller, and the liquid is continuously pressed into the impeller because the pressure above the liquid level of the storage tank is higher than the pressure at the inlet of the pump. Therefore, as long as the impeller is continuously rotated, the liquid is continuously sucked and discharged.
