A leakage-proof sealing device for centrifugal pump installation
By combining multiple sets of driving shafts with a rotating wheel, along with a stepped structure of a limiting ring and a connecting sleeve, the leakage problem of the centrifugal pump shaft seal and connection parts is solved, achieving a highly efficient and stable sealing effect, and adapting to the complex operating conditions of the centrifugal pump.

Abstract
The present disclosure relates to the technical field of centrifugal pump matching tool, and provides a leakage-proof sealing device for centrifugal pump installation, which comprises an outer sleeve, an inner sleeve arranged in the inner part of the outer sleeve, a sealing assembly arranged in the inner part of the outer sleeve, and a lateral connecting assembly arranged on the lateral wall of the outer sleeve and the inner sleeve; a rotating wheel is sleeved on the connecting shaft, and the rotating wheel is in close contact with the inner part of the inner cavity. Through the above technical scheme, the problem that the sealing material is easily worn out due to the continuous friction between the pump shaft and the shaft seal material during high-speed rotation in the prior art, thereby reducing the sealing performance and causing the liquid to leak from the gap between the shaft and the pump shell is solved. The traditional packing seal often uses materials such as graphite wire and hemp rope. When these materials are used to face the high-speed rotating pump shaft, the wear rate is extremely fast, not only frequent maintenance and replacement are required, but also the liquid leakage is difficult to effectively prevent, and there is also the technical problem of environmental pollution.
