L3.3—17/320氢氮压缩机是小化肥厂进行合成氨生产的主要设备,作者对该机进行了技术改造。改造后取消了气缸和填料函的注油点,实现了整机无油润滑。机内一、二、三段活塞环改用填充聚四氟乙烯(PTFE),使用寿命16000小时,四、五和六、七段改用金属塑料,使用寿命分别为10000和4000小时。一、二和六段填料寿命分别为16000和10000小时,均达到或超过了部颁标准。此改造方案自1981年实施以来,实际运行证明工作稳定,性能良好,生产合成氮的能力为9.5吨/台·天,符合设计要求。实现无油润滑后,每台机每年净节约费用13000元左右。
L3.3-17 / 320 Hydrogen Nitrogen Compressor is a small fertilizer plant for the production of ammonia, the main equipment, the author of the machine for technological transformation. After the renovation canceled the filling point of the cylinder and stuffing box, to achieve the whole machine without oil lubrication. The first, second and third piston rings are filled with polytetrafluoroethylene (PTFE). The service life is 16,000 hours. The metal plastics are used in the fourth, fifth, sixth and seventh sections, and the service life is 10000 and 4000 hours respectively. One, two and six sections of packing life of 16,000 and 10,000 hours, respectively, have reached or exceeded the ministerial standards. Since its implementation in 1981, this transformation program has proved to be stable and has good performance. Its capacity to produce synthetic nitrogen is 9.5 tons / day and meets the design requirements. After achieving oil-free lubrication, each machine net cost savings of about 13,000 yuan a year.
