With the development of our country's industry, there are many kinds of micro-pumps on the market, so it is very important to acquire the micro-pumps with good quality and acquire certain knowledge. Xiaobian now introduce to you what to pay attention to when buying a miniature pump. Things to pay attention to the purchase of micro-pump 1, the pump flow must be based on the user courtyard planting, breeding, processing and life of water demand, water conditions and use to choose. If the water is more adequate, then the main water demand to determine the maximum pump model specifications. 2, select the head of the pump when you select the nameplate pump head lift should be greater than the actual height. Under normal circumstances, should be about 20% larger than the actual lift. Similarly, the pump suction head (to allow the vacuum suction height) should also be greater than the actual suction head, otherwise, the pump is difficult to pump water. 3, at present, the miniature pump according to the requirements of the motor power requirements, there are requirements of the three-phase power supply motor, the voltage is 380 volts; have required single-phase power supply motor, the voltage is 220 volts, so the purchase should pay attention. General household lighting power supply is 220V, optional 220V power supply micro-pump more economical and convenient. 4, the water is well water, but also consider the borehole diameter and the maximum diameter of the pump with. If you choose WQ series submersible pump, 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. If you want to choose WXB series of micro-pump, you should consider the well and the well assembly form (direct counterpart pumping, the original pipe supporting pumping, with the hand pump with pump, etc.) feasibility program.
