Does anyone here know about jet pumps? Could you give some information on them?

A jet pump utilizes the conversion of energy through fluid flow to achieve transportation. It can be used to transport liquids as well as gases. In chemical production, steam is often used as the working fluid in jet pumps to create a vacuum and thus generate negative pressure within the equipment. Therefore, it is often called a steam jet pump. 　　Working principle: During operation, water vapor is ejected from the nozzle at high speed under high pressure, creating a certain negative pressure in the surrounding area. This negative pressure draws in low-pressure gases or vapor into the fast-flowing fluid. The gas that has been drawn in mixes with the water vapor and enters the expansion tube, where its velocity gradually decreases, resulting in an increase in static pressure. Finally, the mixture is discharged through the outlet. 　　Also known as jet pumps and ejectors. A pump that uses the jet action of a high-pressure working fluid to convey the fluid. It consists of a nozzle, a mixing chamber, and an expansion tube, etc. 　　When the working fluid is ejected at high speed through a nozzle under high pressure, a low pressure is created in the mixing chamber; the fluid being conveyed is drawn into this mixing chamber, mixes with the working fluid, and then enters the expansion tube together. As the fluid passes through the expanded tube, its pressure rises gradually again ； Then it is discharged outside the tube. 　　Based on the working fluid used, they are generally divided into two categories: steam jet pumps and water jet pumps. It has a simple structure and is easy to use. However, the resulting head is small, the efficiency is low, and the fluid being transported is diluted by mixing with the working fluid, which limits its range of application. 　　Used in the chemical industry, power engineering, and other fields.
