[0001] The utility model relates to the technical field of water ring vacuum pump accessories, and more specifically to an impeller structure of a water ring vacuum pump which is easy to replace. Background Art

[0002] Water ring vacuum pump (abbreviated as water ring pump) is a rough vacuum pump, the ultimate vacuum it can obtain is 2000 ~ 4000Pa, and the vacuum degree of the unit formed with a vacuum pump can reach 1 ~ 600Pa. Water ring pump can also be used as a compressor, called water ring compressor, which is a low-pressure compressor with a pressure range of 1 ~ 2×10^5Pa gauge pressure.

[0003] After searching, the existing announcement number CN217327681U is a water ring vacuum pump impeller, including a sleeve and a disc body, the sleeve body has a mounting groove in the middle, the center line of the sleeve body of the mounting groove is collinear, a plurality of groups of protrusions are arranged on the inner wall of the mounting groove, the plurality of groups of protrusions are evenly distributed circumferentially with the center line of the mounting groove, and a groove is arranged between two adjacent groups of protrusions, the protrusions and the grooves are a waist-shaped structure, the disc body is arranged on the outer wall of the sleeve body, a ring plate is arranged on the outer ring of the disc body, a plurality of ribs are fixedly connected to the inner wall of the ring plate, a plurality of groups of blades are fixedly connected to the outer wall of the ring plate, the blades are an arc-shaped structure, the upper and lower ends of the blade root are aligned one by one with the upper and lower sides of the ring plate, so that the impeller and the shaft form a mutually interlocking structure, and after working for a long time, the structure is stable and not easy to break.

[0004] When the impeller of the vacuum pump is installed relative to the transmission output shaft of the driving motor, the impeller is sleeved on the outside of the transmission shaft and then locked and fixed with bolts. However, since the inner diameter of the mounting hole on the impeller surface is slightly larger than the diameter of the transmission shaft, multiple fine-tuning of the hole is required during the plug-in process, and the installation efficiency is low. Therefore, we propose a water ring vacuum pump impeller structure that is easy to replace to solve the above problems. Utility Model Content
