| Popis: |
The efficiency of pump operation mainly depends on the maximum permissible wear of the parts of their flow path. One of the factors determining the need for repair and restoration of centrifugal and axial pumps is the wear of parts that form the sealing and slotted gaps of the impellers. With an increase in the design clearances of the impellers, the leakage of liquid increases proportionally, and this worsens the energy performance of the pumps and, accordingly, leads to an increase in operating costs. At certain clearance values, the costs reach such a value that the pump operation becomes impractical. Therefore, when assessing the pump's performance, it is important to establish the wear limits of its parts. About a machine part, the limit state is a state in which its further operation is impossible due to an unrecoverable decrease in operating efficiency below the permissible level or the need for repair. |
