2009年兰郑长成品油管道试运投产期间,出现了流量监测设备不具备投用条件,充水初期流量控制难度较大,兰州低压区停泵超压,清管器发送时机选择不当,气阻影响输油泵正常运行,以及过滤器误切换等问题。指出了问题产生的原因及相应的处理措施,比如根据泵机组的“流量-扬程”特性曲线,通过计算泵机组提供的扬程,推断出站流量;控制干线流量的出站调节阀开度宜小不宜大;在给油泵和输油主泵之间设置安全阀;在水充满0号高点和7号阀室的第2个U形管段后发球等。其中的实践经验对今后成品油管道的投产作业具有工程借鉴意义。 During the trial run of Lanzhou-Chengchang oil product pipeline in 2009, the flow monitoring equipment did not have the conditions for commissioning, the flow control was difficult in the early stage of water filling, the over-pressurization of pump in Lanzhou low-pressure area, improper timing of pig’s timing, Impedance affect the normal operation of the oil pump, as well as filters and other issues wrong switch. Pointed out the cause of the problem and the corresponding treatment measures, for example, according to the “flow - lift ” characteristic curve of the pump unit, by calculating the lift provided by the pump unit, inferred outbound traffic; outbound control valve opening Should be small should not be large; set the safety valve between the pump and the main pump of the oil supply; after the water is filled with No. 0 high and the No. 2 U-shaped pipe section of the No. 7 valve chamber serve. One of the practical experience of the future operation of oil products pipeline project has a reference.
