(1) When the water pressure and water pressure of the water source can not guarantee the water volume and water pressure requirements of the system at the same time, an independent water supply pump group should be set up.
(2) The working main pump and the standby pump shall be set up according to the proportion of one transport, one reserve or two transport and one reserve. The water supply capacity of the standby pump shall be no less than one main pump.
(3) The water supply pump and pressure stabilization pump of the system should adopt self-irrigation water absorption mode.
(4) When natural water sources are used, measures should be taken to prevent the blockage of impurities in the suction nozzle.
(5) There should be no less than two suction pipes per set of water pumps.
(6) The suction pipe of the water supply pump shall have a control valve, and the outlet pipe shall have a control valve, a check valve, a pressure gauge and a water test valve with a diameter not less than 65 mm. When necessary, safety relief valves should be installed to prevent system overpressure.
