1. Under conditions permitted by the geographical environment, the water pump should be as close as possible to the water source to reduce the length of the suction pipe. The foundation of the water pump installation should be firm and the special foundation should be repaired for the fixed water pump station.
2. The inlet pipe should be sealed and reliable, and must have special support. It should not be hung on the water pump. For the inlet pipe with the bottom valve, the axis of the bottom valve should be installed perpendicular to the horizontal plane, and the angle between the axis and the horizontal plane should not be less than 45°. When the water source is a channel, the bottom valve should be above 0.50 meters above the bottom of the water, and the net should be prevented from entering the water pump.
3. The machine and water pump base should be level and the connection with the foundation should be firm. When the machine and water pump belt drive, the belt is tightly pressed, so that the transmission efficiency is high, the steering of the water pump impeller should be consistent with the direction indicated by the arrow; when the coupling is used for transmission, the machine and the water pump must be coaxial.
4. The installation position of the water pump should meet the requirements of allowing the vacuum height to be absorbed. The foundation must be level and stable to ensure that the direction of rotation of the power machine is consistent with the direction of rotation of the water pump.
5. If there are multiple units in the same equipment room, there should be a distance of more than 800mm between the unit and the unit.
6. The suction pipe of the water pump must be well sealed, and the elbow and gate valve should be minimized. When the water is filled, the air should be exhausted. During the operation, the air should not accumulate in the pipe. The suction pipe should be slightly inclined to connect with the water inlet of the water pump. There is a certain depth of submersion.
