The paper describes the structure of high pressure water injection unit, working principle. The mechanism of the centrifugal pump sliding bearing is analyzed, the structure characteristics of the sealing device and the relationship between friction, wear and leakage in the sealing device are introduced. Cause seal the main reason for damage, understanding the structure of the device there will be targeted maintenance and management methods. The production process, water injection unit structure, the auxiliary structure of a profound understanding of the function, can improve the technical quality, strengthen routine maintenance management procedures and improve the level of skills.
