Pipeline pumps are widely used in industrial and building water supply and drainage fields because of their simple installation, compact size, and easy maintenance (without removing the pipeline). Here is a summary of the general installation requirements for pipeline pumps:
1. The recommended installation method for pipeline pumps is vertical installation, that is, the water inlet and outlet are parallel to the ground. In some places, if other restrictions require horizontal installation (the water inlet and outlet are vertical to the ground), the power should not exceed 4KW.
2. The base of the pump should be kept as level as possible to prevent the motor bearings and shaft seals from being easily damaged by unbalanced forces. Generally, in order to prevent the accumulation of air at the water inlet end, the water outlet end can be slightly lower than the water inlet end, which can effectively prevent air from accumulating in the pump chamber and causing a lack of pressure.
3. Whether the pump is used alone or in combination with the water pump control cabinet for automatic operation, it is recommended to install inlet and outlet gate valves for water in and out to facilitate maintenance and debugging.
4. If the water outlet has a higher height upward, it is recommended to install a one-way valve or a water hammer preventer at the water outlet.
5. It is recommended to install soft connections at the water inlet and outlet of the pump to facilitate installation and maintenance and to prevent vibration from being transmitted to the external pipe.
6. The inlet and outlet pipes of the pump should have independent supports, and the weight of the pipes cannot be added to the pump.
7. The water inlet pipe of the pump must be larger than or equal to the pipe at the water outlet of the water pump to prevent the water inlet from not being able to keep up with the pressure during water supply.
8. The water inlet of the pump should not be too long, especially when the water source is lower than the pump, the length and height must be paid attention to, otherwise it will not be able to absorb water or serious cavitation will occur.
9. The end of the water inlet pipe equipped with a bottom valve should be kept vertical. If it cannot be kept vertical, the valve will not close on its own, causing water leakage.
