The inlet and outlet sizes of the pneumatic diaphragm pump shall be selected to match the diameter of the connected pipeline. The flow rate of the pump depends on the supplied air pressure. The actual flow rate can be estimated approximately by the following formula:Q≈Qn×（P÷0.6）×η 气动隔膜泵的进出口通径应与系统管路尺寸相匹配，避免因管径过小产生节流、阻力过大，导致实际流量下降、能耗增加。 泵的实际输出流量主要由进气压力决定，可采用以下经验公式近似计算：Q≈Qn×（P÷0.6）×η | |||||||
