DCLアクチュエータは高地でも使用可能か？
High-altitude environments present unique challenges that can impact the performance of DCL electric actuators. This report evaluates their usage at 3,000 meters above sea level. 1. How High Altitude Affects Electrical Products As altitude increases:✔ Air density and pressure decrease, leading to lower insulation strength and increased risk of electrical breakdown.✔ Cooling efficiency decreases, causing higher temperature rise in motors and electronics.✔ Lubricants evaporate faster, and gases or liquids are more likely to leak from sealed components.✔ Temperature drops, with large day-night fluctuations, affecting mechanical parts.✔ Lower humidity reduces insulation but increases brush wear in motors.✔ Stronger solar radiation accelerates material aging. Main Impact Areas Electrical insulation and temperature rise […]
なぜ爆発保護が必要なアクチュエータがあるのか？
1. What is an Explosion? An explosion occurs when flammable substances mix with oxygen and ignite under certain conditions. If the reaction speed exceeds the speed of sound, it results in a destructive explosion wave. 2. What is Explosion Protection? To prevent explosions, at least one of the three key factors must be controlled: Flammable substances Oxygen Ignition source Since flammable substances and oxygen are often unavoidable in industrial environments, the ignition source must be controlled. Electrical equipment is a potential ignition source due to:✔ Surface heating during operation✔ Electrostatic discharge✔ Sparks from electrical currents Explosion-proof electrical equipment is designed to prevent excessive surface temperatures and electrical sparks, ensuring […]
