Structure of centrifugal pump

The basic components of a centrifugal pump are a high-speed rotating impeller and a fixed worm-shaped pump casing. Usually centrifugal pumps have a number of (usually 4-12) backward curved vane impeller fastened to the pump shaft, and with the pump shaft driven by the motor for high-speed rotation.

The working principle of centrifugal pump

After the centrifugal pump starts, the pump shaft will drive the impeller together for high-speed rotational movement, forcing the pre-filled liquid between the blades to rotate, under the action of inertia centrifugal force, the liquid from the center of the impeller to the periphery for radial movement.

The working principle of well submersible electric pump

2023-06-29

Before using the well submersible electric pump, the suction pipe of the well submersible electric pump and the pump need to be filled with liquid. After the well submersible electric pump starts to run, its impeller is rotating at high speed, and the liquid in it will rotate together with the vanes.

Jet pump is a fluid-powered pump. Fluid power pump has no mechanical drive and mechanical work components, it uses the energy of another working fluid as a power source to transport low-energy liquid, which has good safety when used to pump flammable and explosive materials. Jet vacuum pump is a device that uses a high speed jet through the nozzle to pump out the gas in the container to obtain vacuum, also called jet vacuum pump. In chemical production, it is often used for the purpose of generating vacuum.

The working fluid of jet pumps can be gas (air or vapor) and liquid. Common ones are water vapor jet pump, air jet pump and water jet pump. There is also a kind of jet pump with oil as medium, namely oil diffusion pump and oil booster pump, which is the main equipment used to obtain high vacuum or ultra-high vacuum.
