一、抽水机的位置要尽查靠近水源，以减少进水管的长度。二、整个进水管沿水流方向逐渐上升，不能有拱起部分，以免存留空气，影响工作效益。三、为减少进水管中的水头损失，应使进水管的直径大于水泵进口，而在水泵近口处，用锥形管将二者连接。进水管与水泵相连接时，若有弯 First, the location of the pump to do check near the water to reduce the length of the inlet pipe. Second, the water inlet pipe along the flow direction of the gradual rise, can not have arched part, in order to avoid leaving the air, affecting work efficiency. Third, in order to reduce the head loss in the water inlet pipe, the diameter of the water inlet pipe should be larger than that of the water pump inlet. At the near mouth of the water pump, the two pipes should be connected with the tapered pipe. When the inlet pipe and the pump are connected, if there is a bend
