Pump flow. Users according to the courtyard planting, breeding, processing and living water demand, water conditions to consider the use of conditions. If sufficient water, according to the maximum water demand to determine the pump flow. Make sure that the flow of the selected pump is basically in accordance with water demand and water conditions. Pump head. Pump head should be greater than the actual water level. Under normal circumstances, the head of the selected pump wxb series should be 20% larger than the actual lift; wq series should be 10% larger than the actual lift. Otherwise, the pump is difficult to pump water. Power supply. The motor voltage for the three-phase power supply is 380 volts; the motor voltage for the single-phase power supply is 220 volts. General household lighting power supply is 220 volts, therefore, the purchase of 220 volt power supply micro-pump more economical and convenient. Installation size matching. Such as the use of micro-submersible pump wq series, we should pay attention to the maximum diameter of the pump should be less than the hole diameter, otherwise it can not be installed into the well. Such as the selection of wxb series of micro-pump, should be considered good and well assembly form (direct counterpart pumping, the original pipeline supporting pumping, hand pump with pump, etc.) the feasibility of the program.
