油流量标准装置是常规的流量标准装置之一,较水、气装置相比,具有实流测量的优势。但检测效率较低,主要原因之一是夹表管道残油排放缓慢。设计一套夹表管道残油吹扫方案应用于油流量标准装置,方案充分利用现有资源,改造工作量小,实用性强,能够使得管道中排油迅速、干净、封闭,有效提高油流量标准装置的检测效率,同时避免了油的挥发和环境污染。 Oil flow standard device is one of the conventional flow standard devices, compared with water and gas devices, with the advantages of real-time measurement. However, the detection efficiency is lower, one of the main reasons is that the residual oil in the pipeline of the clamp meter is drained slowly. Design a set of table pipe residual oil purge program used in oil flow standard device, the program make full use of existing resources, the transformation of small workload, practicality, can make the pipeline discharge oil quickly, clean, closed, effectively improve the oil flow The detection efficiency of the standard device, while avoiding the volatilization of oil and environmental pollution.
