1. Inlet design:

(1) Inlet pipe: Composed of two parts, the transmission pipe and the distribution pipe, its length should be equal to the distance of water conveyance and should not be less than 10 meters.

(2) Pipe Distribution System: Composed of three parts: distribution branch pipes, main distribution pipes, and vertical distribution pipes; the height should not be less than 0.5 meters.

(3) The diameter of the inlet branch pipe is 50-60mm; the diameter of the inlet and outlet branch pipes is approximately 40mm; the diameter of the inlet and outlet vertical pipes should be greater than 30mm, and not less than 15mm.

(4) When the lift height of the water pump is not less than 20 meters, a single-stage centrifugal pump can be used. For lift heights greater than 20 meters, it is advisable to use a multi-stage centrifugal pump or parallel operation of multiple pumps for water lifting.
