Tipi di attuatori e come scegliere quello giusto
Actuators can be classified based on their driving method into the following categories: 1. Electric Actuators Electric actuators use an electric motor as the power source, converting electrical energy into mechanical motion to drive the valve. Advantages: ✔ Adjustable speed✔ High positioning accuracy✔ Large torque output Disadvantages: ✖ Thermal effects of the motor may trigger […]
In che modo l'umidità riduce la durata di vita degli attuatori (valvole elettriche)?
Humidity is well known to cause damage to electronic components. One of the primary ways humidity reduces the lifespan of electric actuators is through ionic migration short circuits. 1. What is Ionic Migration Short Circuit? Ionic migration occurs when moisture and contaminants on a circuit board facilitate the movement of ions between conductors, leading to […]
Che cosa significa il ciclo di lavoro S2 negli attuatori (valvole elettriche)?
Many people have questions about the S2 duty cycle in actuators or electric valves. What does it mean, and why is it defined this way? 1. The Origin of S1, S2, S3, and S6 Duty Cycles The S1, S2, S3, and S6 duty cycles originate from electric motor classifications, with a primary focus on thermal […]
Gli attuatori DCL possono essere utilizzati in zone ad alta quota?
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 […]
Perché i segnali di uscita di tensione oscillano in determinate condizioni?
1. Voltage Signal Transmission Path As shown in Figure 1, a voltage signal transmission system consists of three key components: Negative feedback voltage output circuit Signal transmission cable Includes parasitic capacitance (C1) and parasitic inductance (L1), which depend on cable length and wiring layout. Input signal acquisition circuit May include a low-pass filter (L2, […]
