6ES7360-3AA01-488806模块备件英文说明

内部和外部的泄露对安全构成威胁。其它的自控制阀一般都是从阀杆上伸出，通过电空，液动驱动器来控制阀芯旋转或移动。这需要处理长时间工作的阀杆动态密封件的外泄漏；力士乐电磁阀仅靠电磁力来密封磁断路套筒上的内铁芯来实现，没有动态密封、易堵塞泄漏。与其它类型的执行机构相比，它们的成本也较低并且易于安装和维护。更显而易见的事实是，自我管理体系总是如此简单，并且总是如此廉价。力士乐电磁阀是用开关式信号来控制的，这样就可以很容易的与工程计算机相连。

Internal and external leaks pose a threat to security. Other automatic control valves generally extend from the valve stem and control the rotation or movement of the valve core through electro pneumatic and hydraulic drivers. This needs to deal with the leakage of the dynamic seal of the valve stem working for a long time; Rexroth solenoid valve only relies on electromagnetic force to seal the inner iron core on the magnetic circuit breaker sleeve, which has no dynamic seal and is easy to block leakage. Compared with other types of actuators, they are also low cost and easy to install and maintain. The more obvious fact is that self-management systems are always so simple and always so cheap. Rexroth solenoid valve is controlled by switch signal, so it can be easily connected with engineering computer.
