information on the projects and small production capacity of Chinese engineering machinery put into production in the first half of this year

Guide: Recently, The key technology research and application of high-performance hydraulic piston pump, a major special project of science and technology in Hunan Province led by Sany Heavy Industry, passed the mid-term on-site evaluation at Sany Changsha headquarters and received an excellent rating. The evaluation was organized by the Department of science and technology of Hunan Province, a member of the Party group and the head of discipline inspection of the Department of science and technology of Hunan Province

recently, a seven person expert group led by Caojian, executive chairman of China Plastics Processing Industry Association, led by Sany Heavy Industry to carry out a major special course of science and technology in Hunan Province, went to Changping Town to investigate the topic "research and application of key technologies of high-performance hydraulic piston pump" which passed the medium-term on-site evaluation at Sany Changsha headquarters and received an excellent rating. The evaluation was organized by Hunan Provincial Department of science and technology, and Yang Wei, member of the Party group and discipline inspection team leader of Hunan Provincial Department of science and technology, and the heads of relevant departments and offices of Hunan Provincial Department of science and Technology participated in the evaluation

this major project was approved in 2010, with a total investment of 15million yuan. Some of the relevant material industry specifications drafted by the metal materials, oil and other sub committees have been published since the project was established and implemented for one year. Five core technologies, such as the return mechanism of the fixed clearance hydraulic piston pump with pressure plate and the impeller pre pressurization device, have been overcome, four high-performance hydraulic piston pump prototypes have been developed, and five technical patents (including two invention patents) have been applied for. After the completion of trial production, the plunger pump will be applied in Sany pump truck and trailer pump
