油气回收是资源循环利用、环境保护、持续发展的动力，更是全球治理和社会发展需要。化石能源开采、输运、使用过程中挥发性油气不断产生，收集处理这些气体的装备涉及到真空泵、压缩机等。抽速和真空度是真空-压缩机最重要、互相关联参量，不同类型的真空泵有不同的气量测定理论、方法和规范。定压法和定质量流量是最常用的方法，传统测量方法采用手动控制测量元件，取得原始参数，再套入标准、规范公式计算出真空泵和压缩机的流量值（抽速）和对应压力（真空度）。但是这种测试方法大部分采用水银柱、油柱标识压力值、差压值，可能造成污染和人体损坏，不符合《关于汞的水俣公约》之规定，也无法实现智能化测试。为此依据气量测量原理，研究并实施了自动化采集数据和计算实现真空泵气量、压力等主参数的测量、记录、整理，并通过数据库建立、比对，对测量对象做出符合性、等级判定。该测试系统推广到工程中，通过现代网络技术与设计者、客户等建立实时的分析、调试和远程控制通道，实现油气回收输运装备分系统模块的数字化自动工作。
Abstract：Oil and gas recovery is the driving force for resource recycling, environmental protection, and sustainable development, and it is also a necessity for global governance and social development. Volatile oil and gas are constantly generated during the extraction, transportation, and use of fossil fuels, and equipment for collecting and processing these gases involves vacuum pumps, compressors, and so on. The pumping speed and vacuum degree are the most important and interrelated parameters of vacuum compressors, and different types of vacuum pumps have different theories, methods, and specifications for measuring gas volume. The constant pressure method and constant mass flow rate are the most commonly used methods. Traditional measurement methods use manual control of measuring elements to obtain raw parameters, and then calculate the flow rate(pumping speed)and corresponding pressure(vacuum degree) of vacuum pumps and compressors by fitting standard and normative formulas. However, most of these testing methods use mercury and oil columns to indicate pressure and differential pressure values, which may cause pollution and human damage. They do not comply with the provisions of the Minamata Convention on Mercury and cannot achieve intelligent testing. Based on the principle of gas volume measurement, we have researched and implemented automated data collection and calculation to measure, record,and organize the main parameters, such as gas volume and pressure of vacuum pumps. Through database establishment and comparison, we have made conformity and grade judgments on the measured objects. This testing system is promoted to engineering, and real-time analysis, debugging and remote control channels are established with designers, customers, etc., through modern network technology to achieve digital automatic operation of oil and gas recovery and transportation equipment subsystem modules.
