Structure of single-stage double-suction split volute centrifugal pump
The single-stage double-suction split volute centrifugal pump is an efficient and stable fluid transportation equipment. Its structural features are mainly reflected in the following aspects:
1. First of all, its most significant feature is that the pump body adopts a split volute design. This design allows the pump body to be horizontally separated along the center line for easy repair and maintenance. When it is necessary to inspect or replace internal parts, you only need to open the two halves of the pump body without disassembling the motor and inlet and outlet pipelines, thus greatly saving maintenance time and costs.
2. Secondly, the impeller adopts a double-suction structure. The double-suction impeller has two symmetrical suction inlets, allowing liquid to enter the impeller from both sides at the same time, thereby balancing the axial force and reducing the vibration and noise of the pump. At the same time, the double-suction structure can also improve the suction performance of the pump and ensure that the pump can still work stably at a lower liquid level.
3. In addition, this centrifugal pump is equipped with an efficient sealing system. Mechanical seals or packing seals are usually used to ensure that the pump will not leak when delivering corrosive or high-temperature liquids. At the same time, the sealing system can effectively prevent external impurities from entering the pump body and ensure long-term stable operation of the pump.
4. Finally, the single-stage double-suction split volute centrifugal pump also has good regulating performance. By changing the speed of the impeller or adjusting the opening of the inlet and outlet valves, the flow and lift of the pump can be easily adjusted to meet the needs of different working conditions.
