高扬程小流量液压隔膜泵是国内输送固液两相介质的新泵种 ,它的主要部件之一就是用以隔离工作油液与输送介质的橡胶隔膜 ,隔膜在隔离罐体中的位置如图 1所示。图 1　橡胶隔膜检测系统橡胶隔膜起到 2个基本作用 :一是把 2种不允许接触和混合的不同介质分隔开来 ,并往复运动 ,实 High-lift low-flow hydraulic diaphragm pump is a new type of pump for transporting solid-liquid two-phase medium in China. One of its main components is a rubber diaphragm for isolating working fluid and conveying medium. The position of the diaphragm in the isolated tank is shown in the figure 1 shown. Figure 1 rubber diaphragm detection system rubber diaphragm plays two basic roles: First, the two do not allow contact and mixing of different media separated and reciprocating motion, the real
