大家帮我研究下这句话!? the philosophy of the natural gas letdown stations is to have two (2) parallel runs of regulators. each of the parallel runs in the pressure reduction station are capable of operating at full plant rates. the set points for each regulator are different, and the pilot control tie-ins are located down stream on the low pressure piping for each. the regulator in one run is set higher than the regulator in the opposite run. 天然气降压站的基本原理是用2个并行线调压器.每一条线都可处理整个装置的流量.两个调压器的设定压力不同,先导控制分别接在每条管线的下游低压段.其中一条管线的调压器设定压力比另一条高.查看更多
