Analysis and Treatment Measures of PDS Valve Fault in Polypropylene Plant
Maoming Petrochemical 200,000 t/a polypropylene device product discharge system PDS cut-off valve,due to the valve's high-speed switching and high frequency of action,it is required to have a very strong resistance and wear resistance,and the actuator and accessories are also very high requirements.Based on this,the paper introduces the failure condition of high frequency PDS valve in polypropylene plant,analyzes the failure and expounds the measures taken to reduce the failure rate and increase the service life.
