Abstract
The invention discloses a high-hardness abrasion-resisting corrosion-resisting sliding bearing and relates to the technical field of hydraulic transmission. Sealing rings added at the connecting position of a pump shaft and the sliding bearing and connected with a magnetic transmission liquid ring vacuum pump driven by a motor by using a magnetic transmission coupler. The magnetic transmission liquid ring vacuum pump comprises the motor and uses the magnetic transmission coupler without inside-outside non-contact transmission to replace a mechanical coupler. A rolling bearing is replaced by a ceramic sliding bearing, and four sealing rings are added at the connecting position of the pump shaft and the sliding bearing to completely eradicate circumferential leakage between the sliding bearing and an installing gear of the pump shaft. Axial gaps of an impeller, a bearing box and an inner magnetic part are regulated by using oil-resisting insulating paper. The inner magnetic part is located in a sealing space of a spacer sleeve, and sealed internal circulation is formed in a delivery liquid circulation and delivery space. Spill, bleeding, dropping and leakage phenomena in the chemical engineering corrosive liquid delivery process are completely eradicated in structural design and application, and the problems of personal harm and environmental pollution caused by leakage in the chemical engineering corrosive liquid delivery process are solved.
