Beschreibung
Zusammenfassung:	The invention discloses a method for preventing water leakage of a cylindrical junction surface, which is used for sealing the junction surface of a water channel between an inner shaft and an outer sleeve of a sleeve, and comprises the following steps: determining the pressure of the junction surface according to the water pressure in the water channel; determining rigidity coefficients of the outer sleeve and the inner shaft according to the pressure of the joint surface; the thickness of the outer sleeve, the thickness of the inner shaft and the radius of the joint surface are determined according to the rigidity coefficient, and the rigidity coefficient is in positive correlation with the thickness of the outer sleeve and the thickness of the inner shaft and is in negative correlation with the radius of the joint surface. The structure comprises the inner shaft and the outer sleeve which are in interference fit, the thickness of the outer sleeve is larger than the first preset thickness, the thickness of
