“The cooling water temperature is 89 degrees Celsius, which is 10 degrees lower than before; the temperature parameters in other areas are normal. On July 14, Sang Weiyang, the shift leader of the Wen Er Lian pressure boosting station in the Wen Liu gas transmission management area of the Zhongyuan Oilfield’s natural gas production and sales plant, uploaded images taken by the unit’s automatic control system after checking the operation status of the No. 5 pressure booster. This means that the “High-Temperature Rectification Campaign for Large-Scale Booster Units” carried out in the Wenliu Gas Transmission Management Area has completely resolved the issue of high temperatures in these units. The failure rate of large-scale operating equipment increases as it ages. After years of operation, the two large pressure boosting units at the Wen’erlian pressure boosting station have successively experienced issues such as reduced power output. Two of these units successively encountered the \"three highs\" problem of high exhaust temperature, high water temperature, and high air temperature. High temperatures can cause the automatic control system to shut down, and may even affect the stability of gas supply in the gathering and transportation system. To this end, the district established a high-temperature troubleshooting team for the units, assigning personnel to conduct analysis and research on the faulty units. First, they conducted thermographic analysis of the unit’s operation to identify patterns of abnormally high temperatures. Then, they developed effective, stable, and energy-saving cooling and airflow management solutions; furthermore, new temperature controllers were installed in the older units, which effectively resolved the issue of high temperatures in those units. At the same time, the task force also analyzed the heat dissipation and corrosion conditions of the unit’s air coolers. On one hand, new heat dissipation and convection channels were installed in areas where hot air tended to accumulate; on the other hand, multiple new cooling fin sets were added, and the unit’s heat dissipation circulation system was cleaned, thereby completely resolving the issues related to high temperature, high pressure, and high humidity.
