(1) The paraffin hydrogenation unit of Daqing Refinery is the Italian New Billion Machine. It is a localization and has invited four well-known and wholly-owned manufacturers to participate in the unsuccessful. In 2006, we drove successfully and avoided the direct friction between the eccentric piston and the cylinder. The accident, tracking and evaluation for 10 months is still in operation. After that, the localization of the Lulu Refinery, Heze Refinery, and Panjin Petrochemical equivalent machines have achieved satisfactory results.

(2) Satisfactory results have been obtained for the sealing of special gases such as high-purity nitrogen, argon gas, sulfur hexafluoride and military medium and high pressure compressors.

(3) The gas filling stations of Zhongyou Jieneng System, such as Yinchuan, Liaohe, Jilin, Jinan, etc., use domestically produced natural gas compressor parts and accessories such as the United States, Spain, and the United Kingdom.

(4) In the chemical fertilizer industry, remarkable achievements have been made in the transformation of 32MPa nitrogen and hydrogen seals. For example, the seal packing of the piston rod circulation machine of Panjin Fertilizer Plant has been reformed, and the continuous operation for 7 months continues to operate. After the end of the week of operation, after the director Qi said funny: we will not get overtime pay later.

(5) In the bottle making line: contracted nearly 100 sets of air compressors (mostly foreign products, small parts are domestically produced) of Zhongfu Container Company throughout the country for normal operation and localization of accessories.

(6), successfully solved: low temperature, variable working compressor seal design, such as low temperature natural gas of -160 ° C, non-lubricated intake -90 ° C, three-stage exhaust 92 ° C low temperature ethylene compressor, achieved the expected results.
