1. Use the front -induced wheel to ensure that the liquid stream can work in advance in the front induction wheel, which can increase the pressure of the liquid flow a lot.

2. Use a double -suction wheel to enable the liquid flow to enter the impeller together from the sides of the impeller. When the imported section doubles, the flow rate of the import will double.

3. The use of a slightly larger positive angle can increase the import angle of the blade, reduce the curvature of the leaves in the import of the blade, reduce the leaves, and then increase the import area. Improve large flow conditions for improvement can reduce losses. However, the positive angle should not be too impact on efficiency.

4. Use anti -air erosion materials. According to practice, the higher the hardness, strength, and toughness of the material, the better the stability of the chemistry, and the stronger the performance of the resistance of the gas.

5. Increase the pressure of the liquid surface in the pre -storage tank in front of the centrifugal pump, which can increase the amount of steam erosion.

6. Reduce the losses on the front pipeline of the centrifugal pump. If the pipeline is shortened as much as possible within the required range, the curved pipes and valves in the pipeline will be reduced, and the valve opening is increased as much as possible.

7. Improve the design structure of the centrifugal pump into the design structure near the impeller. Increase the area of overcurrent, increase the radius of the inlet section of the leaf wheel cover, speed up the fluid flow and reduce blood pressure, appropriately reduce the thickness of the leaves of the leaves and the leaves of the leaves to ensure that its streamlined type can be reduced, and it can also reduce the winding around. Acceleration and antihypertensive heads of flow leaves. Reduce the smooth resistance of the impeller and the surface of the inlet part of the blade, extend the edge of the leaves into the impeller inlet to ensure that the liquid flow will be improved in advance to increase the pressure.
