金属管件气密性检测装置的控制系统设计

摘要：
在日常的生产制造中，生产铸造的管件、容器、内燃机缸盖等零件，为了保证产品的品质和生产的安全，需要对这些零件的气密性进行检测，同时检测装置的自动化设计有利于提高检测效率。
本文改进设计了手动式检测装置的气动系统，概述了改进后气动系统的工作原理及动作实现过程；针对各种控制方案的优缺点，确定用PLC做为控制系统的核心，并结合气动回路设计出检测装置的控制系统。该系统通过PLC控制电磁阀的开闭，从而控制气动回路中高压气体的流向，使装置完成各个运动过程，实现管件气密性检测。
该系统的运用可以使此装置实现自动化检测，提高检测效率。控制面板简单，易于操作。系统以可编程控制器为控制核心，使系统抗干扰能力强、可维护性好，且可以在比较恶劣的环境下工作，以适应工业化检测。

Metal pipe gas leakage detection device for control system design
summary:
In daily production in the manufacturing, production of casting pipe fittings, container, internal combustion engine parts such as cylinder heads, in order to ensure product quality and safety of production needs to these parts of the gas - tightness test, while detecting device of automatic design improves the detection efficiency.
This improved design manual - detecting device of the pneumatic system, overview of improved aerodynamic system working principle and action process ; for a variety of advantages and disadvantages of control programmes, of PLC to control system for determining core, combined with pneumatic control system of circuit design detection device. Closing of the system by PLC control solenoid valve to control pneumatic circuit of high pressure gas flow, make the device through the campaign process, realization of gas tightness detection of pipe fittings.
The system can make to the application of the automatic detection device, improving detection efficiency. Control Panel is simple, easy to operate. Systems with programmable controller to control the core, making the system anti-interference ability, good maintainability, and can be in a relatively poor working environment, to adapt to the detection of industrialization.
Key words : air tightness ; checked by water ; test control system
