Three installation methods of horizontal multistage centrifugal pump
No matter what horizontal multistage centrifugal pump is installed before use, if the installation is incorrect, the pump will become unusable or even cause damage to the centrifugal pump. The basic level and elevation should be reviewed before the pump is in place. The centerline alignment, horizontal alignment, and elevation alignment of the pump are the key to the installation process.
1. Multi-stage pump center line alignment
Centerline alignment is to align the vertical and horizontal centerlines of the pump. First set the vertical and horizontal center lines on the top surface of the foundation, and then hang the vertical lines at the inlet and outlet flange surfaces of the pump (double-suction centrifugal pump) and the center of the shaft. Adjust the position of the pump so that the vertical line coincides with the vertical and horizontal centerlines on the foundation.
2. Multi-stage centrifugal pump level alignment
Horizontal alignment is to align the vertical and horizontal levels of the pump. Generally, a single-stage centrifugal pump is measured on the pump shaft and the outlet flange by means of a spirit level or a hanging vertical line.
3. Horizontal multi-stage pump elevation alignment
The elevation of the pump refers to the elevation of the axis of the pump. The purpose of elevation correction is to check whether the elevation after the installation of the pump is consistent with the designed elevation, and measure with a spirit level and a spirit level. During the measurement, stand one level on the height Hs of the known level, and set the other level on the pump shaft.
