具有电子监控的空气阀和活塞的往复泵
摘要：
本发明提供一种气动泵(10)，所述气动泵(10)使用安装在空气马达(18)的阀座(16)中的磁体(14)和两个安装在阀盖(22)中的簧片传感器(20)，以监控阀(16)的速度和位置。螺线管(24)安装在阀盖(22)上，并且可控制螺线管以将柱塞(26)延伸至阀座(16)中，从而停止阀的运动并由此阻止泵的失控。磁阻传感器(34)设置在空气马达(18)的中部以精确地监控活塞(36)的位置并通过空气阀传感器(20)提供泵(10)的精确控制和诊断所必须的输入并使其适于测量和多种构件应用。
摘要（英）：

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. A magnetoresistive sensor 34 is located in the center of the air motor 18 to precisely monitor the piston 36 position and with air valve sensors 20 provides the input necessary for precise control and diagnostics of the pump 10 and makes it suitable for metering and plural component application.
