From appearance, vertical pump is standing and horizontal pump is horizontal.
The connection form is different, the vertical pump is connected vertically from bottom to top, the horizontal pump is vertically arranged on the base, and the vertical pump is known as the vertical pipe centrifugal pump, the motor and the pump body are the children's connection. Horizontal pump is connected by coupling and motor, which needs to be found regularly.
The floor space is different, the vertical pump occupies a small area and the horizontal pump occupies a large area. The vertical pump group is smaller than the horizontal pump, not necessarily the foundation; The horizontal pump unit has a base to lay the foundation.
The maintenance difficulty is different. It is difficult to repair the vertical pump. If the upper part of the impeller needs to be removed, the upper part can be carried out. The horizontal pump IS relatively easy, such as the IS type pump can carry on the impeller maintenance as long as the inlet pipe IS removed.
The installation is different, the vertical pump is the overall connection, the installation is easy; After the horizontal pump installation, it needs to adjust the precision.
In general, the pump often USES horizontal, and in the following situations, the vertical wine pump needs to be used.
1) the pump should be installed at a low water level in a place where the water level fluctuates greatly. In this case, vertical position can be used to reduce the area of the pump station and reduce the earthwork. Lower infrastructure investment. Large single suction centrifugal pumps and axial pumps are mostly vertical.
2) draw deep underground water. For liquids such as oil or brine, vertical deep well pumps are required.
3) the large single suction pump is a vertical one because it can be used to lubricate the bearing with simple structure, when the water lubrication bearing is small and the bearing life is increased.
4) some small flow pump high pressure, due to the series, pump shaft, slender and prone to not run smoothly, change the situation of one of the measures is to use the vertical pump, and makes the pump bearing under certain pulling force.
5) using the potential energy to increase the cavitation margin of the impeller inlet, the pump is placed in the lowest position, such as vertical condensation pump, in use.
6) the floor area of the pump is limited, such as the Marine pump.
