2 型式参数特点 SABROE公司活塞式压缩机在型式参数上有如下特点 (1)短行程转为长行程在60年代,为了减小压缩机运动零件的惯性力和最大加速度,便于减轻机器的振动和噪音,各国中小型活塞式压缩机基本由过去的长行程(即S/D≥1)转为短行程(S/D<1),其值一般处在0.7～0.8左右,表9为SABROE公司旧系列和我国系列的S/D值。 70年代以后,由于科学技术的发展,工艺水平的改进,制造检验质量的提高。同时希望 2 Type Parameters Features SABROE piston compressors have the following characteristics in terms of type parameters: (1) short stroke to long stroke In 1960s, in order to reduce the inertia force and maximum acceleration of moving parts of compressor, it is easy to reduce the vibration of the machine and Noise, small and medium-sized piston compressor in all countries by the long-term (S / D ≥ 1) to the short stroke (S / D <1), its value is generally 0.7 to 0.8 or so, Table 9 SABROE Old series and our country series S / D value. After the 1970s, due to the development of science and technology, the improvement of the technological level, the improvement of manufacturing inspection quality. At the same time hope
