1. Different forms from appearance. Vertical pump is vertical direction standing, horizontal pump is horizontal direction lying.
2. Different connection forms. Vertical pump bottom-up superposition connection, motor and pump body is a sub-port connection; The horizontal pump is longitudinally arranged on the base. The horizontal pump is connected with the motor by a coupling.
3. Different footprint. Vertical pump occupies a small area and horizontal pump occupies a large area. The floor area of vertical pump group is smaller than that of horizontal pump, it is not necessary to build the foundation; Horizontal pump group is provided with a base, to build the foundation.
4. Different maintenance difficulties. The maintenance of the vertical pump is difficult, such as the maintenance of the impeller needs to be removed from the upper part of the rear can be carried out; The horizontal pump IS relatively easy, such as IS pump as long as the inlet pipe can be removed to carry out impeller maintenance.
5. Different installation forms, vertical pump as a whole connection, easy installation; The horizontal pump needs to be adjusted after installation.
In general, the pump often uses the horizontal pump, and in the following cases, the need to use the vertical pump 1. In the place where the water level changes greatly, the pump should be installed according to the low water level. At this time, the vertical one can reduce the area of the pump station and reduce the earthworks. Reduce infrastructure investment. Large single suction centrifugal pump and axial flow pump are mostly vertical.
2. Suction of deeper groundwater. Oil or brine and other liquids, need to use vertical deep well pump.
3. Another reason that large single suction pump is vertical is that water lubricated bearings with simple structure can be used. At this time, the load of water lubricated bearings is small, and the wear is light to increase the bearing life.
4. Some high pressure and small flow pumps, due to the number of series, the pump shaft is slender, easy to appear unstable operation, one of the measures to change this situation is to use vertical pump, and make the pump bearing by a certain tension.
5. The use of potential energy to increase the cavitation allowance at the inlet of the impeller, the pump in use to put the first stage impeller inlet in the lowest position, such as vertical condensate pump.
6. The floor area of the pump is limited, such as the Marine pump.
