杭州汽轮机厂的同志赴西德参观西门子公司威塞尔工厂,考察工业汽轮机制造工艺时,引进了国际上七十年代推广应用的液压夹具和高压小流量泵站的性能参数。我厂于81年制成了SYZ—250型泵站。经过进一步改进,试制了YJZ型液压夹具泵站(见图1)小批试制品已
Comrades from Hangzhou Steam Turbine Plant visited Siemens Wiesel Plant in West Germany to investigate the performance parameters of hydraulic fixtures and high pressure low flow pump stations popularized and applied in the world in the 1970s when examining the manufacturing process of industrial steam turbines. Our factory made SYZ-250 pumping station in 81 years. After further improvement, trial production of YJZ hydraulic fixture pump station (see Figure 1) small batch of prototype has been
