Water Ring Vacuum Pumps can be seen from the technical data of foreign technologically advanced companies that when a single-stage water ring vacuum pump is equipped with a one-stage atmospheric ejector, when the suction pressure is 5kPa, the pumping rate can reach the pump without atmospheric ejection. The pressure is 65-70% of the pumping rate at the 400hPa point. When the two-stage water ring vacuum pump is equipped with an atmospheric ejector, the pumping rate at the suction pressure of 1.5kPa can reach the suction pressure of the pump without an atmospheric ejector. It is 70--75% of the pumping rate at 8kPa point. This water ring vacuum pump sample greatly expands the application range of water ring vacuum pumps. In order to further promote the application, it is necessary to study and improve the design of the atmospheric ejector and the ratio of the water ring vacuum pump. Because the air flow in the tapered section of the nozzle of the atmospheric ejector and the diffuser is supersonic, and the momentum exchange during the mixing process of the air and the pumped gas is more complicated, the water ring vacuum pump cannot rely on theoretical calculations. The method is designed and many experiments are carried out. However, from the perspective of expanding the application of water ring vacuum pumps and improving its efficiency, it is necessary to strengthen experimental research and strive to improve its pumping efficiency. However, with the strengthening of technological progress in various industries and the improvement of the reliability requirements for the entire vacuum system, the reliability requirements for it are correspondingly higher.

Therefore, the design and development of energy-saving water ring vacuum pumps and compressors as soon as possible to eliminate outdated products with high energy consumption and low efficiency is an important task for the design, development and production of water ring vacuum pumps. The water ring vacuum pump adopts an optimized design method, and strives to improve the efficiency of the pump and reduce the energy consumption. Water ring vacuum pumps and water ring compressors are products with high energy consumption and low efficiency. This is a recognized fact. Small pumps are generally 30-35%, and large pumps are 40% or slightly higher. Such low efficiency is not good for electromechanical products. The requirements of China and China’s current energy shortage situation are extremely incompatible.
