“In the first half of this year, through the joint efforts of all parties, the reliability of the West-to-East GE/NP and electric-drive compressor group has been greatly improved.†Recently, the person in charge of the operation of the compressor group of the West-East Gas Pipeline Company told reporters .
According to briefings, at present, there are 18 compressor stations on the entire pipeline of the West-East Gas Pipeline. At the highest peak, there are 24 world-class 30 MW compressor units running at the same time. The daily delivery of natural gas is up to 45 million cubic meters.
In the first half of this year, GE/NP units had a total of 38,000 hours of operation, which was 2.1 times the same period of last year. The number of failures was only 42% of last year, and the number of failures per thousand hours was also reduced from 10.3 last year to 2.05. In the first half of the year, the electric drive unit had a total operation of 11,600 hours, which was close to the full-year operating time last year. The breakdown rate per thousand hours was reduced from 4.4 to 3.5.
It is reported that since the beginning of last year, the gas transmission capacity of the West-East Gas Pipeline has increased significantly, and the compressor's operating time has also risen substantially. This has ensured that the pressure for safe and steady gas supply to pipelines has increased substantially, and long-term full-load operation has greatly shaped the compressor group. Security risks.
In order to ensure the reliability of the “heart†of the pipeline, the reliability of the compressor group, this company has established a compressor group troubleshooting team to analyze and summarize the failures of the compressor group in the past few years. The research team has completely reconstructed the external circulating water system, filter ventilation system, compressed air and drying system that have the greatest impact on the compressor, which greatly reduced the number of breakdowns.
In addition, each management office along the West-East Gas Pipeline strictly implements the equipment management responsibility system, complies with the operation and maintenance operating procedures of the compressor unit, and promptly inspects and maintains each system of the compressor unit to comprehensively improve the reliability and availability of the equipment.
