一九八五年成都电焊机研究所完成了以下六项科研、新产品成果。其中前五项属国家经委、部下达的“六五”科技攻关节能新产品研究课题。前四项于一九八五年底通过了部级鉴定,后两项分别于十月、十二月完成了所鉴定。 1.ZX5系列可控硅整流弧焊机 ZX5可控硅整流弧焊机用以取代效率低、耗能大、噪声大、耗材多的旋转式直流弧焊机,具有明显的节能效果,每年每台焊机节电可达5000度。以1500台计,每年可节电750万度,可省铜和钢材260吨,如以1500台/年的递增速度投放市场,到1990年可基本上取代旋转直流焊机生产。它是我国直流弧焊电源更新换代的理想的节能新产品之
In 1985, Chengdu Electric Welding Machine Research Institute completed the following six scientific research, new product achievements. Among them, the top five belong to the “Sixth Five-Year” scientific and technological breakthroughs in energy-saving new products research projects issued by the State Economic Commission and Ministry. The first four passed the ministerial level appraisal in the end of 1985, and the last two completed the appraisal in October and December respectively. 1.ZX5 series SCR rectifier arc welding machine ZX5 SCR rectifier arc welding machine to replace the low efficiency, energy consumption, noise, supplies more rotary DC arc welding machine, with significant energy savings, each year Taiwan welding machine energy saving up to 5000 degrees. With 1,500 units, it can save 7.5 million kilowatt-hours per year and save 260 tons of copper and 260 tons of steel. If it is put on the market at a rate of 1,500 units / year, it will basically replace the production of rotary DC welder by 1990. It is the ideal new energy-saving new product of DC arc welding power source in our country
