Application risk analysis and preventive measures of electric actuators in chemical plants

Electric actuators  (such as TheobornElectric Actuators) are widely used in automation scenarios such as valve control and fluid regulation in chemical plants, which can significantly improve production efficiency and control accuracy. However, due to the peculiarities of the chemical production environment, valveElectric Actuators may face a variety of risks during operation. In this paper, we will analyze the potential risks ofElectric Actuators in chemical plants and propose corresponding optimization solutions.

Risks and countermeasures from environmental factors
1. Effect of corrosive media
Chemical production often involves corrosive media such as strong acids, alkalis, or organic solvents, which can corrode the housing, seals, and internal circuitry of electricActuators. Long-term exposure to corrosive environments can cause equipment such as electricActuators to deteriorate or even fail.
Solution:
Valve electric actuators with stainless steel housings or special anti-corrosion coatings (e.g. PTFE, epoxy resins).
Regularly check the sealing performance of the actuator to prevent media from penetrating.
2. The effects of extreme temperatures
High temperatures can accelerate the aging of electronic components, while low temperatures can cause lubricants to solidify, affecting the efficiency of electric actuators.

Solution:
Choose a high- or low-temperature resistant KEMS electric actuator to ensure that it is suitable for the operating range from -40°C to 80°C.
Add insulation or heat dissipation devices in extreme environments, and check the lubrication status regularly.

Electrical system risks and optimization solutions
1. Power fluctuations
Unstable voltage or sudden power loss may cause the electric actuator to malfunction or the motor to burn out.
Solution:
Install a regulated power supply or UPS (uninterruptible power supply) to ensure the stable power supply of Kems electric actuators.
The electric actuator with overload protection is used to avoid damage caused by abnormal current.
2. Hidden danger of electrical failure
Problems such as short circuits and aging insulation can lead to equipment failure and even fire, especially in flammable and explosive areas.
Solution:
Regularly check the insulation performance of the cable to ensure that the terminal blocks are tightened.
Choose explosion-proof valve electric actuators, which meet explosion-proof standards such as Ex d/IIC T6.
Mechanical structure risk and maintenance strategy
1. Mechanical wear and fatigue
After long-term operation, gears, bearings and other components may be worn, resulting in the accuracy of the valve electric actuator deteriorating or stagnating.
Solution:
Develop a maintenance schedule for regular lubrication and replacement of wear parts.
Choose high-quality brands such as Kems electric actuators, and their wear-resistant design can extend the service life.
2. Vibration and shock effects
Vibrations generated during the operation of pumps, compressors, and other equipment in chemical plants can affect the stability of electric actuators.
Solution:
Shock-absorbing brackets or flexible connection devices are used.
Vibration-resistant electric actuators are preferred to ensure reliable operation in vibration environments.

Critical points of safety protection
1. Risk of media leakage
If the seal of an electric actuator fails, it can lead to the release of hazardous chemicals, threatening personnel safety and the environment.
Solution:
Valve electric actuator with double seal or bellows seal design.
Regularly inspect key parts such as seals and stuffing boxes.
2. Explosion-proof safety requirements
In oil, gas or chemical flammable areas, electric actuators must be certified for explosion protection.
Solution:
Kems explosion-proof electric actuators are selected to ensure that they have passed ATEX, IECEx and other certifications.
Installation and maintenance in strict accordance with explosion-proof specifications to avoid accidents caused by electrical sparks.

conclusion
Although the application of electric actuators (such as Bohn electric actuators, valve electric actuators, etc.) in chemical plants faces multiple risks such as corrosion, temperature, electrical, and mechanical, the failure rate can be greatly reduced and the stable operation of the production system can be ensured through reasonable selection, regular maintenance and installation of protective measures. Enterprises should choose suitable high-quality electric actuators  according to their own working conditions, and establish a complete maintenance system to ensure the safety and reliability of automatic control.
