我厂的4M12压缩机六段气缸无油润滑工作寿命达6000多小时,开创了小化肥厂大型压缩机中使用无油润滑技术的良好开端。从使用情况可知,大型压缩机设计技术参数较合理,因此其无油润滑改造不会比L型压缩机困难。 我厂主要产品为氨和纯碱,现有生产能力为年产合成氨三万吨,纯碱六万吨。合成氨部份采用碳化煤球和块煤制气,ADA法 Our factory’s 4M12 compressor six-cylinder cylinder oil-free lubrication life of more than 6000 hours, creating a small fertilizer plant in the use of large oil-free lubrication technology a good start. It can be seen from the usage situation that the technical parameters of the large compressor design are reasonable, so that its oil-free lubrication reform will not be more difficult than the L-type compressor. Our main products for ammonia and soda ash, the existing production capacity of 30,000 tons of synthetic ammonia an annual output of 60,000 tons of soda ash. Synthetic ammonia part of the use of carbonized briquettes and lump coal gas, ADA method
