1. The appearance is different, the vertical pump is standing and the horizontal pump is lying horizontally.
2. The connection mode is different. The vertical pump is superimposed and connected from bottom to top. The horizontal pump is arranged vertically on the base. The vertical pump is called the pipeline pump, the motor and the pump body are connected to the sub-port; the horizontal pump is connected with the coupling. The motor is connected and needs to be regularly corrected.
3. The occupied space is different, the vertical pump covers a small area and the horizontal pump takes up a large area. The vertical pump set occupies less than the horizontal pump and does not have to be laid; the horizontal pump set has a base and the foundation is to be laid.
4. The maintenance difficulty is different. It is difficult to repair the vertical pump. For example, the inspection of the impeller needs to remove all the upper parts before it can be carried out. The horizontal pump is relatively easy. For example, the IS type pump can remove the inlet tube and perform the impeller maintenance.
5. Different installation forms, the vertical pump is connected as a whole, and the installation is easy; and the horizontal pump needs to be adjusted after installation.
6. Horizontal pumps are economically superior to vertical pumps.
The vertical pump has a small footprint and is suitable for use in places where the site is tight. The horizontal pump is suitable for ample space, but the horizontal pump is installed firmly. The vertical pump needs to consider the reaction force caused by the pressure of the outlet pipe, so it is necessary to prevent dumping. Measures, especially not applicable to the installation of spring cushions, in the "Code for acceptance of construction quality of building water supply and drainage and heating engineering" (GB 50242-----2002) 4.4.6 Vibration damping devices for vertical pumps should not be used Spring damper. Provisions.
The horizontal pump of the same power is different from the vertical pump. The vertical pump can be directly opened and stopped. The horizontal pump can not be directly opened and stopped. Before the opening, there must be a string of water process and the closing of the gate to start the shutdown. Horizontal pumps have "one-step" operation problems. The detailed questionable questionable price of the control box of the same power should be the same? Because the control circuit and the control components inside are the same, answering is not the same if you consider the "one-step" operation, otherwise it is the same. Such as overcurrent and overvoltage protection, fast break delay protection and so on.
