As an important part of explosion-proof electrical equipment, explosion-proof solenoid coils play a vital role in hazardous environments such as petroleum, chemical, and mining. However, many users have found that the life of explosion-proof solenoid coils is often short, which not only increases the cost of equipment maintenance, but also may cause safety hazards. So, what are the reasons for the short life of explosion-proof solenoid coils? This article will analyze them from multiple perspectives.

I. Environmental factors:
Explosion-proof solenoid coils are often deployed in extremely harsh environments that pose severe challenges to the coils.
• Dust and corrosion: In environments such as coal mines and chemical plants, dust and corrosive substances in the air will deposit on the surface of the coil, causing the insulation performance to deteriorate and accelerating the aging process.
• High temperature and humidity: High temperature and humidity are the two major killers of coil life. High temperature accelerates thermal aging of insulation materials, while humidity may cause internal short circuits in the coil, leading to failure.
• Vibration and shock: In an environment with frequent mechanical vibration and shock, the coil’s fixing parts may loosen and the winding wire may break due to fatigue, thus affecting its service life.
II. Operation and maintenance:
In addition to environmental factors, improper operation and maintenance are also important reasons for the short life of explosion-proof solenoid coils.
• Misoperation: Wrong operation, such as wrong voltage access, overload operation, etc., may cause permanent damage to the coil.
• Lack of maintenance: Regular cleaning, inspection and testing of the coils are key to ensuring their long-term stable operation. However, many users tend to ignore this point, causing the coil to age and fail unknowingly.
• Improper maintenance: Incorrect maintenance methods, such as using inappropriate cleaning agents, replacing mismatched parts, etc., may cause secondary damage to the coil.
III. Product quality:
Product quality is one of the key factors affecting the life of explosion-proof solenoid coils.
• Material defects: If there are defects in the insulation material, winding material, etc. of the coil, it will directly affect its performance and life.
• Manufacturing process: The quality of the manufacturing process directly affects the reliability and durability of the coil. For example, inaccurate winding process and poor welding quality may cause the coil to malfunction during use.
IV. Strategies to prolong life:
In order to extend the life of explosion-proof solenoid coils, we need to start from multiple aspects and implement comprehensive protection and scientific maintenance.
• Optimize the environment: Improve the installation environment of the coil, reduce the accumulation of dust and corrosive substances, and maintain appropriate temperature and humidity.
• Standard operation: Connect and use strictly according to the operating procedures to avoid misoperation and overload.
• Enhanced maintenance: Clean, inspect and test coils regularly to identify and address potential problems in a timely manner.
• Choose high-quality products: When purchasing coils, pay attention to choosing products with superior quality and exquisite manufacturing technology to ensure reliable material quality.
Although the explosion-proof solenoid coil is small, its role in industrial production cannot be ignored. In order to ensure production safety, we must pay attention to the life of the coil, start from the source, provide comprehensive protection, and perform scientific maintenance. Only in this way can we ensure that these key equipment can operate stably in harsh environments and safeguard the safe production of enterprises.
