Influence of gas content in transmission medium on performance of single stage centrifugal pump
In order to ensure the reliable operation of a single-stage centrifugal pump, it's essential to take specific measures aimed at minimizing the gas content in the fluid being pumped.

(1) The design of the suction cup and the layout of the suction piping should be structured to allow even liquid intake across parallel pumps. The suction nozzle must have a certain submergence depth (H1) within the suction cup and maintain a minimum vertical distance (He), as shown in Figure 2-126. This helps prevent air entrainment and ensures smooth flow.
(2) The inlet pipe, return line, and waste collection pipes should be positioned away from the pump’s suction nozzle to avoid drawing in air bubbles or vapor pockets. Additionally, the suction pipe should not be placed in the center of the tank, nor too close to the walls—ideally, it should be at least 1.5 times the pipe diameter (1.5D) away from the wall. This prevents vortices or air suction, as illustrated in Figure 2-126.
(3) It is crucial to ensure all pipe connections are properly sealed to prevent air leaks, which can significantly reduce pump efficiency and cause cavitation.
(4) When laying out the suction piping, care should be taken to avoid any sections where air pockets could form, as shown in Figure 2-127. These air pockets can lead to unstable flow and damage the pump over time.
By following these guidelines, you can greatly improve the performance and longevity of your centrifugal pump system. Always double-check your installation and maintenance procedures to ensure optimal operation.
