The financial sector reported on March 25, 2024 that according to the announcement of the State Intellectual Property Office, Shanghai Rychen Technologies Co.,Ltd. obtained a project called "Self-priming Centrifugal Pump", authorized announcement number CN108775287B, and the application date is July 2018.
The patent abstract shows that the present invention relates to a self-priming centrifugal pump, which includes a sub-impeller hydrodynamic sealing device. The sub-impeller hydrodynamic sealing device includes a sealing bottom plate, a sub-impeller, a fixing key, a sub-impeller volute, a lock nut, a fastening screw, the blade and the front cover plate of the impeller. The blade outlet angle is 20-35, the blade wrap angle is 120-160, and the blade number is 5-8, the gap between the blade and the front cover plate of the impeller is 0.5~1.5mm, the diffusion angle of the clamping flow channel is 0~3 °, the sealing bottom plate is fixedly connected with the support frame fixed on the top of the gas-water separation chamber, the auxiliary impeller and the auxiliary impeller volute are located inside the gas-water separation chamber, and the auxiliary impeller is installed on the drive shaft through a fixing key and locked by a locking nut, the auxiliary impeller volute is located behind the outlet of the auxiliary impeller and is installed on the sealing bottom plate through fastening screws. The power consumption of the auxiliary impeller is ≤ 5%, and the centrifugal pump efficiency is 72% ~ 80%. The auxiliary impeller of the self-priming centrifugal pump of the invention has small labor consumption, high efficiency and excellent promotion value.
