Problems solved by technology

However, in actual use, especially in the use of highly corrosive media used in petrochemical industries, it often causes corrosion and peeling inside the electric and cylinder, which not only affects the sensitivity and control parameters of the electric actuator, but also shortens the electric actuator. The service life of the actuator cylinder leads to the overall scrapping of the entire electric actuator, which also affects the safe production of the enterprise, resulting in high operating costs for the enterprise and poor long-term operation stability. Therefore, it is necessary to improve the material of the existing electric actuator cylinder through technology , effectively improve the service life of electric actuators, and meet the promotion and use of petrochemical and other highly corrosive industries
