沈阳气体压缩机厂生产的2DZ5.5-1.4/285-320型循环机于1981年9月在我厂投产运行,至今情况良好。在安全、稳产、降低消耗、提高经济效益方面效果显著,是当前小氮肥厂较理想的循环机。 一、特 点 该机为对置型卧式循环机。它采用组合式平十字头,避兔了径向跳动;应用了背压自封原理,屉式组合填料盒同轴度好,提高了密封效果。创新的单连杆结构,使得设计简化、维修方便。填料与活塞环采用自润滑材料,在循环机上首次取得了满意效果。
The 2DZ5.5-1.4 / 285-320 circulating machine produced by Shenyang Gas Compressor Factory was put into operation in our factory in September 1981 and has been in good condition so far. In the safe, stable production, reduce consumption, improve economic efficiency, the effect is significant, is the ideal small nitrogen fertilizer plant recycling machine. First, the characteristics of the machine for the horizontal horizontal recycling machine. It uses a combination of flat crosshead, to avoid the radial runout; the application of the principle of back pressure self-sealing, drawer combination of good packing box, improve the sealing effect. Innovative single-link structure, making the design is simplified, easy maintenance. Filler and piston ring with self-lubricating material, for the first time in the recycling machine has achieved satisfactory results.
