大多数机器和工艺设备的机座,其金属用量占机器总金属用量的15～20％。目前,苏联每年有2万多台泵和压缩机采用钢筋混凝土代替金属作机座,由此每年可以节约4000吨金属,降低成本100万卢布。当设备直接安放在厂房地面上时,因同时利用钢筋混凝土底座结构作为基础,不必专门建造大 Most machinery and process equipment, the base, the amount of metal accounts for the total amount of metal machine 15-20%. At present, more than 20,000 pumps and compressors in the Soviet Union use reinforced concrete instead of metal as a base each year, thus saving 4,000 tons of metal per year and reducing the cost by 1 million rubles. When the equipment is placed directly on the ground floor of the plant, because at the same time using the reinforced concrete base structure as a foundation, do not have to specifically build large
