され得ない。Recently, mechanical seals have been adopted to solve the above problem, completely preventing leakage, etc. In this mechanical seal, the members attached to the rotor shaft side and the casing side maintain contact with each other while moving relative to each other in a plane perpendicular to the axis, and prevent leakage in this plane. A spring is used to press the rotating surface to prevent the two members from separating. therefore,
Considering the role of the mechanical seal, the cross section of the rotor shaft where this mechanical seal is installed is as follows:
The fan must be circular, for example, its cross section should be cut out into a D shape, the shape of the boss hole of the fan should correspond to the cross section of the shaft, and the fan should be mounted on the rotor shaft, and a mechanical seal should be installed on the outside of the fan. cannot be implemented.
