Reciprocating Pump With Electronically Monitored Air Valve Having Battery And Solenoid Electronic Monitoring
摘要：
An air operated pump (10) uses a magnet (14) mounted in the valve cup (16) of the air motor (18) and two reed sensors (20) mounted in the valve cover (22) to monitor the speed and position of the valve (16). A solenoid (24) is mounted on the valve cover (22) and can be commanded to extend a plunger (26) into the valve cup (16) to stop valve movement and therefore the pump from running away. Three methods may be used to increase battery life and monitor the solenoid plunger position, two of which use the changing inductance of the solenoid (24) to monitor the solenoid movement.
摘要（中）：

气动泵（10）使用安装在气动马达（18）的阀杯（16）中的磁体（14）和安装在阀盖（22）中的两个簧片传感器（20）来监测 阀（16）。 螺线管（24）安装在阀盖（22）上，并且可以命令将柱塞（26）延伸到阀杯（16）中，以阻止阀移动，因此泵不会离开。 可以使用三种方法来延长电池寿命并监视螺线管柱塞的位置，其中两个使用螺线管（24）的变化电感来监测电磁铁的运动。
