Industrial jet pumps, also known as jet pumps and injectors. A pump that utilizes the jetting effect of high-pressure working fluid to transport fluids. Composed of nozzles, mixing chambers, and expansion tubes. For the sake of smooth operation, a vacuum chamber (also known as a suction chamber) is installed at the throat; In order to ensure sufficient mixing of the two fluids, there is a mixing chamber behind the vacuum chamber. During operation, the working fluid is sprayed out from the nozzle at a high speed, creating low pressure in the vacuum chamber, causing the conveyed liquid to be drawn into the vacuum chamber and then into the mixing chamber. In the mixing chamber, high-energy working fluid and low-energy conveyed liquid are fully mixed to exchange energy with each other, and the speed gradually becomes consistent. When entering the diffusion chamber through the throat, the speed slows down and the static pressure rises, achieving the purpose of conveying liquid.
