(Summary description)The 8 INCH SUBMERSIBLE RADIAL PUMP manufacturer believes that the fluid in the submersible pump not only acts on the impeller but also acts on the pump casing, and is transmitted to the base part through the pump casing to cause the vibration of the unit. The force on the pump casing is also changing at different times. . However, the radial force is always biased in one direction, and an elliptical trajectory similar to the radial force of the impeller appears.

Information

  The 8 INCH SUBMERSIBLE RADIAL PUMP manufacturer believes that the fluid in the submersible pump not only acts on the impeller but also acts on the pump casing, and is transmitted to the base part through the pump casing to cause the vibration of the unit. The force on the pump casing is also changing at different times. . However, the radial force is always biased in one direction, and an elliptical trajectory similar to the radial force of the impeller appears.

8 INCH SUBMERSIBLE RADIAL PUMP

  The 8 INCH SUBMERSIBLE RADIAL PUMP manufacturer found that the outlet section of the pump casing is basically in a high pressure state. When the radial force is the largest, the blades are basically in the third quadrant, and most of the entire volute is in the high-pressure area; when the radial force is the smallest, the blades are basically in the first quadrant. , the overall pressure distribution of the volute is low, and the high-pressure area is concentrated in the outlet section, which also directly leads to the smallest radial force of the pump casing at this time;

  The 8 INCH SUBMERSIBLE RADIAL PUMP manufacturer feels that the position where the radial force of the volute changes abruptly is the same as the position where the radial force of the impeller changes abruptly. At this time, the blade outlet is just at the position of the separation tongue. This is because the flow cross section after the blade sweeps the separation tongue.

  The area of the 8 INCH SUBMERSIBLE RADIAL PUMP is the smallest, and the manufacturer of the 8 INCH SUBMERSIBLE RADIAL PUMP feels that the flow is continuously squeezed under the condition of the vane, so that the surface pressure of the pump casing in the fourth quadrant reaches the highest level. In addition, the dynamic and static interference between the water and the separator makes the flow uneven. , resulting in the sudden change of radial force.
