海上采油树电动节流阀制造质量控制

Quality Control of Electric Throttle Valve for Offshore Christmas Tree

海上平台无人化改造已成为未来趋势,远程电控采油树被逐步推广应用。为确保采油树电动节流阀在无人平台上的有效运行,从设备生产制造阶段的源头上把控质量,分析总结电动节流阀驻厂监理工作的技术要点,应用质量控制图监测分析电动执行机构制造过程中关键性能指标是否处于受控状态。结果表明,该监理方法的实施可有效识别电动节流阀生产制造阶段的缺陷及隐患,可为后续的电动采油树驻厂监造及质量控制提供参考。

Unmanned transformation of offshore platforms has become the future trend,and remote electric control Christmas tree is gradually applied.In order to ensure the effective operation of Christmas tree electric throttle valve in the unmanned platform,we con-trolled quality from the source of the equipment production stage,analyzed and summarized the technical points of the on-site supervi-sion of electric throttle valves,and also monitored and analyzed whether the key performance indicators in the manufacturing process of the electric actuator are under control by the use of the quality control chart.The results show that the implementation of the supervision method can effectively identify the defects and hidden dangers in the production and manufacturing stage of the electric throttle valve,which can provide a reference for the subsequent on-site supervision and quality control of the electric Christmas tree.
