Abstract:

Intelligent actuator is the key equipment of ethylene plant, and it plays an important role in guaranteeing the long period operation, energy consumption and economic benefit of ethylene plant. In this paper, the frequent failures of an intelligent actuator in an ethylene plant are taken as the example, an in-depth analysis is performed on the reasons for the failures, the structure, working principle, characteristics and common failures of an intelligent actuator in ethylene plant are discussed, and some preventive measures and corresponding maintenance and treatment measures are put forward for the failures of actuator.

Key words: ethylene plant, actuator, failure, maintenance
