It will be more lively with everyone's participation, and the sea will be more exciting with you. Everyone is welcome to participate in the forum to exchange and discuss the high temperature in July, and pay attention to fire prevention. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * The first three-cylinder single-acting hydraulic diaphragm pump developed and produced by Chongqing Water Pump Company for coal slurry transportation in hydrogenation units passed an 8-hour non-stop water test. The performance of the unit met the requirements of the technical agreement and the one-time test run was successful. Finishing work such as painting and carton sealing is currently underway, waiting for shipment to the user site. This equipment is the core equipment of the coal-water slurry device of a company in Zhangye's 200,000 tons/year medium-temperature tar hydrotreating project. It directly feeds the gasification furnace. This contract is also the first time that the heavy pump company's coal slurry feed pump has entered the field of coal-water slurry transportation in the coal gasification process. In the development process of the first coal slurry feed pump, newly developed and designed cylinder sealing technology, valve technology, intelligent oil supply and discharge diaphragm stroke control technology and exhaust technology were used. The successful test of this project not only provided the company with further breakthroughs in the field of high-pressure coal slurry feed pump technology, but also laid the foundation for subsequent research and development of four-nozzle coal slurry feed pumps. Since components such as motors and outlet buffers are provided by users, it becomes more difficult for the company to test the water on site. Relevant personnel from the operations department, general assembly workshop, and slurry pump room were on the front line to solve problems in hot weather. They actively deployed and borrowed other contract-related parts for assembly testing, overcame relevant difficulties, and successfully completed the trial run of the company's first coal slurry feed pump. The successful development of the coal slurry feed pump laid a solid foundation for the company's diaphragm pumps to enter the coal slurry market and diversify diaphragm pump products.
