我公司变压吸附(简称PSA)制氢装置真空泵P501共6台,在运行过程中频繁停机,给生产造成极大影响,此问题解决后发现设计与电缆敷设上存在一些问题,现将问题分析与处理方法总结如下,供大家借鉴。一、真空泵P501控制原理真空泵P501具备现场与远程(DCS)两种控制方式。机前由转换开关进行控制切换,当转换开关置于远程时,DCS操作台可进行远程启停控制,并且泵启停直接与电动阀联锁。
Our company pressure swing adsorption (PSA) hydrogen production unit vacuum pump P501 a total of six units in the operation of the frequent downtime, to produce a tremendous impact, this problem is solved and found that there are some design and cable laying problems, the problem analysis And the treatment method is summarized as follows, for your reference. First, the vacuum pump P501 control principle Vacuum pump P501 with on-site and remote (DCS) two control methods. The front of the machine is controlled by the change-over switch. When the change-over switch is placed on the remote side, the DCS console can be remotely controlled. The start-stop of the pump is interlocked directly with the electric valve.
