Measures of Raising Use Performance of Mechanical Seal for Ammonia Pump

Li Baoyan Li Shuhua(Daqing Petroleum Institute, Anda 151400)  
Inactivation phenomena of mechanical seal are analyzed and studied for ammonia pump in use process, some parameters are recalculated, reasons of fault are determined and improvement measures are put forward. The measures are applied to ammonia pumps in Daqing Natural Gas Company, satisfied results are obtained in sealing performance and service life, better work environment is acquired, and commercial benefit is notable. Some valuable references of resolving sealing problems of some volatile mediums are given.
