After nearly 10 years of continuous operation, the "three-one-one" pneumatic valve of the compressor has experienced lags in the opening and closing reaction, ineffective operation, and the like, resulting in frequent shutdown of the compressor. How to carry out repairs makes it difficult for everyone.
The "three-to-one" pneumatic valve is a key critical control point for the compressor. If imported from a U.S. factory, it will take two to three months to arrive, and its foreign exchange price will be as high as nearly 50,000 U.S. dollars, or 30 yuan. Million!
As the temperature gradually declines, once the maintenance of the compressor fails to keep up, it will seriously affect the offshore natural gas outbound mission in winter. Before the “cost reduction and efficiency increaseâ€, the task group of the Haisan Union Station decided to challenge the “foreign equipmentâ€.
The group leader Qiao Xiaogang learned that the domestically produced parts could meet the operational requirements of this type of compressor. He decided to “find gold†from domestically produced parts.
Everyone dismantled the faulty valve, all the parts were spread out on the ground, and then each person took one piece, compared with the hundreds of thousands of parts and components accumulated in the usual production and maintenance on the station, to find out the performance parameters and on-site requirements. Close to the accessories. Then through the self-processing and limit adjustment measures, so that the domestic interface and the imported parts match, the valve switching action and control cabinet control signal match. One week later, a domestically-made piece with the same parameters and specifications as the imported one was transformed. After several on-site tests, the domestically produced “three-to-one†valve not only works normally, but also the start-stop operation is more simple and convenient and easy to maintain.
