1、 Advantages of rotary pumps
1. High traffic and high range
The flow rate and head of a rotary pump are relatively large, making it suitable for conveying high flow, high head media such as organic solvents, liquid starch, etc.
2. Stable operation
During the operation of a rotary pump, due to the special design structure, liquid short circuits, cavitation, and vibration generally do not occur, and the operation is very stable, reducing the frequency and cost of equipment maintenance and replacement.
3. Wide applicability
The structure of a rotary pump is simple and can handle various fluids, such as liquids containing gases, high viscosity liquids, liquids containing particles, and volatile liquids.
4. Simple construction and easy maintenance
The rotary pump has a simple structure and easy maintenance, with fewer structural components, making it easy to disassemble and repair.
2、 Disadvantages of rotary pumps
1. There are many vulnerable parts
The structure of a rotary pump is relatively complex and requires supporting equipment such as gears. There are many vulnerable parts, and sometimes they need to be replaced frequently.
2. Sensitivity to medium viscosity
Due to the special structure of the rotary pump, its operation needs to be carried out within a limited liquid diffusion area, which requires high viscosity for the medium flow. High viscosity media can cause unstable flow and phenomena in the rotary pump.
3. Stuck phenomenon
When the rotary pump runs for a long time, it is easy to get stuck due to temperature changes or other issues, and it is necessary to replace the supporting equipment or replace the rotary pump.
4. High price
Due to the high precision requirements for the design and manufacturing of rotary pumps, as well as the high material costs, the construction cost is relatively high.
【 Conclusion 】
In summary, rotary pumps, as a commonly used centrifugal pump, have advantages such as high flow rate, high head, and stable operation. However, they also have disadvantages such as having many vulnerable parts and sensitivity to medium viscosity. In order to ensure the normal operation and service life of the rotary pump, it should be well maintained and serviced.
