摘要
简要介绍VOD水环真空泵的工作原理,并根据工程现场开发经验对水环真空泵的常规控制工艺及多用一备控制技术的实现方法进行了介绍。给出了在PLC中实现水环真空泵单泵启停控制逻辑和真空步控逻辑的具体流程该技术不仅可以用于VOD真空系统,同样适用于选用了水环真空泵的其他真空系统。
The VOD working principle of water ring vacuum pump is briefly described.And based on the project site development experience, the water ring vacuum pump conventional control technology and realization method of multi-prepared control technology are introduced.The realization flow of a single-step water ring vacuum pump stare-stop control logic and vacuum step control logic in PLC is achieved.The technology not only can be used for VOD vacuum system,also be applicable to other vacuum system using the water ring vacuum pump.
