The application differences of the secondary impeller shaft seal in single-stage and multi-stage pumps are mainly reflected in the following aspects:
Structural difference: Single stage pumps only have one impeller, so the design of the secondary impeller shaft seal is relatively simple. Multi stage pumps have multiple impellers and require shaft seals between each impeller to prevent liquid leakage. Therefore, the design of the secondary impeller shaft seal for multi-stage pumps is more complex.
Head difference: Due to the higher head of multi-stage pumps compared to single-stage pumps, the secondary impeller shaft seal needs to withstand a greater pressure difference in multi-stage pumps. This requires the secondary impeller shaft seal material of multi-stage pumps to have higher strength and wear resistance.
Difference in maintenance difficulty: Due to the complex structure of multi-stage pumps compared to single-stage pumps, it is more difficult to maintain and replace the secondary impeller shaft seal for multi-stage pumps. Professional technicians are required for operation.
Application scenario differences: Single stage pumps are usually used in low head, high flow situations, such as agricultural irrigation, urban water supply, etc. Multi stage pumps are commonly used in situations with high head and low flow, such as mine drainage and oil extraction. Therefore, the application of the secondary impeller shaft seal varies in different types of pumps.
Overall, the application differences of the secondary impeller shaft seal in single-stage and multi-stage pumps are mainly reflected in aspects such as structure, head, maintenance difficulty, and application scenarios. When selecting a pump, it is necessary to choose the appropriate pump type and secondary impeller shaft seal according to specific application requirements.
