Quality proportional Injector pump is a type of fluid powered pump. The fluid power pump has no mechanical transmission and mechanical working components, It uses the energy of another working fluid as a power source to transport low-energy liquids, and has good safety when it is used to pump flammable and explosive materials. Quality proportional Injector pump is a device that uses a high-speed jet through a nozzle to extract the gas in the container to obtain a vacuum. In chemical production, quality proportional Injector pump is often used to generate a vacuum.

The working principle of quality proportional Injector pump:
Quality proportional Injector pump utilizes the jetting action of the high pressure working fluid to deliver the fluid. It consists of nozzles, mixing chambers and expansion pipes. In order to make the operation smooth, a vacuum chamber is set at the throat; in order to enable the two fluids to be fully mixed, there is a mixing chamber behind the vacuum chamber. During operation, the working fluid is ejected from the nozzle at a high speed, forming a low pressure in the vacuum chamber, so that the conveyed liquid is sucked into the vacuum chamber, and then enters the mixing chamber. In the mixing chamber, the high-energy working fluid and the low-energy conveyed liquid are fully mixed, so that the energy is exchanged with each other, and the speed is gradually consistent. From the throat into the diffusion chamber, the speed slows down and the static pressure rises to achieve the purpose of conveying the liquid.
