Solvent pump is one of the key pumps in butadiene extraction unit. Its failure will interrupt solvent delivery and lead to unit shutdown. Therefore, the normal operation of this pump directly influences the smooth production of the unit and downstream units. The status of the pump, such as vibration and temperature, is timely monitored and analyzed using an intelligent status monitoring and analysis platform to check the operation of pump bearings and seals. It is particularly important to use the platform to analyze and judge in advance the early failure of pumps. It is necessary to formulate corresponding maintenance strategies, carry out preventive maintenance to solve the faults in operation, prevent serious damage to pumps, extend the service life of equipment, ensure the safe, stable and long-term operation of the unit, and minimize the impact of equipment on production to achieve the best overall performance.
