How to select the type of micro water pump

How to select the type of micro pump: the flow of the pump must be selected according to the water demand, water source conditions and use conditions of the user's courtyard planting, breeding, processing and living If the water source is sufficient, the model and specification of the pump shall be determined mainly according to the large water demand of Zui When selecting the pump head, the head on the nameplate of the selected pump shall be greater than the actual water delivery height Generally, it should be about 20% larger than the actual lift Similarly, the suction head of the water pump (the vacuum height allowed to be suction) should also be greater than the actual suction head, otherwise, it is difficult for the water pump to pump water At present, the micro water pump is distinguished according to the power requirements of the matched motor There are motors with three-phase power supply, the voltage is 380 V; there are motors with single-phase power supply, the voltage is 220 V, so attention should be paid when purchasing The general household lighting power supply is 220 V It is more economical and convenient to choose the micro pump with 220 V power supply If the water source is well water, the matching between the inner diameter of well bore and the large outer diameter of pump body Zui shall be considered If WQ series micro submersible pump is selected, it should be noted that the Zui big outer diameter of the pump should be smaller than the inner diameter of the well bore, otherwise it can not be installed into the well If we want to choose B series micro pump, we should consider the feasible scheme of well assembly form (direct opposite pumping, matching pumping with original pipeline, matching pumping with hand pump, etc.).
