隔膜泵的作用方式只是在选用气动执行机构时才有,其作用方式通过执行机构正反作用和阀门的正反作用组合形成。
The function mode of the diaphragm pump is only when the pneumatic actuator is selected, and its mode of action is formed by the combination of the positive and negative effects of the actuator and the positive and negative effects of the valve.

隔膜泵的流量特性是指介质流过阀门的相对流量与位移(阀门的相对开度)间的关系,理想流量特性主要有直线、等百分比(对数)、抛物线和快开等4种。常用的理想流量特性只有直线、等百分比(对数)、快开三种。
The flow characteristic of the diaphragm pump refers to the relationship between the flow of the medium through the relative flow of the valve and the displacement of the valve (the relative opening of the valve). The ideal flow characteristics are mainly 4 kinds, such as straight line, equal percentage (logarithm), parabola and fast opening. Commonly used ideal flow characteristics are linear, equal percentage (logarithmic) and fast open three.

隔膜泵口径的选择和确定主要依据阀的流通能力即cv。在各种工程的仪表设计和选型时,都要对隔膜泵进行cv计算,并提供隔膜泵设计说明书。
The selection and determination of the caliber of the diaphragm pump is mainly based on the circulation capacity of the valve, that is, CV. In the design and selection of various engineering instruments, the CV calculation of diaphragm pumps is required, and the design instructions for diaphragm pumps are provided.
