on may 6, china energy鈥檚 chemical company smoothly completed a trial operation of its first set of homemade high-pressure coal slurry feed pump, marking a successful test run of the device.
high-pressure coal slurry feed pump is a core equipment for direct coal liquefaction, requiring complex techniques. previously when the company鈥檚 six imported uraca high pressure plunger pumps were all operational, equipment maintenance costs were extremely high due to a lack of spare pumps and long cycle of procurement of some of the wearing parts of the feed pump. domestic development and manufacturing of feed pump can solve this problem.
homemade high-pressure coal slurry feed pump during the test run
the r&d project of homemade coal slurry feed pump was initiated in 2017, and construction began in april 2019. the project contractor overcame the difficulty of simultaneously advancing equipment production and engineering construction, and completed civil foundation construction, equipment installation, process piping, electrical instrument installation and commissioning, single unit trial operation and other steps as scheduled. afterwards, it efficiently organized several rounds of quality examination, water pressure test, interlocking calibration, inverter test, and test pump scheme formulation and approval. during the test run, participants strictly followed the established plan, adjusted the parameters step by step, recorded problems in details and mitigated risks in a timely manner. the results show that the homemade coal slurry feed pump was operating smoothly, with all performance parameters meeting the design requirements.
the successful test run of the chemical company鈥檚 first set of homemade coal slurry feed pump paves the way for verifying the reliability of independently-developed equipment and is of great significance to promoting the localization of key equipment in coal chemical industry.
