The main differences between horizontal centrifugal pumps and vertical centrifugal pumps are reflected in the following aspects:
1.Appearance: The vertical centrifugal pump is vertical, while the horizontal pump is horizontal.
2.Connection form: The vertical centrifugal pump is superimposed from bottom to top, and the horizontal pump is arranged longitudinally on the base.
3.Floor space: Vertical centrifugal pumps have a small footprint, while horizontal pumps have a large footprint.
4.Maintenance difficulty: It is difficult to overhaul the vertical centrifugal pump, such as the maintenance of the impeller can only be carried out after the upper part needs to be removedWhereas, horizontal pumps are relatively easy.
5.Installation form: The vertical centrifugal pump is connected as a whole, and the installation is easyThe horizontal pump needs to be adjusted for accuracy after installation.
In terms of choice, most people want to use a horizontal single-stage centrifugal pump, mainly because the horizontal pump is simple and easy to service and maintain. However, vertical centrifugal pumps also have their own unique advantages and application scenarios.
First of all, vertical centrifugal pumps are usually used in the terrain of underground tank structures, or there is no space on site to lay the foundation for horizontal centrifugal pumps, only vertical centrifugal pumps can be placed on the foundation.
Secondly, horizontal centrifugal pumps have a number of limitations. The self-priming height should not exceed 5 meters, the medium should not be viscous, and the inlet should not leak. Therefore, a vertical centrifugal pump can only be selected if the above conditions are not met.
In addition, if a normal horizontal pump (not a self-priming pump) has a poor self-priming capacity, it is not possible to extract the medium from the tank below. Therefore, horizontal pumps and long-shaft pumps cannot be compared in this regard, which is another advantage of vertical centrifugal pumps.
In the selection of horizontal centrifugal pump and vertical centrifugal pump, it is necessary to consider comprehensively according to the actual situation. When choosing, it is necessary to consider factors such as topography, space, medium characteristics, self-priming capacity, etc., to determine the most suitable pump type.
