DC24V ON-OFFタイプアクチュエータ（電動弁）のしくみ

DCL 24V ON-OFF タイプ電動調節弁をパイプラインに設置する場合、リレー、ON-OFF 制御、PLC（DCS）を使用して制御し、流体の開閉を行うことができます。このガイドでは、DCL 24V ON-OFF タイプ電動アクチュエータがリレー、PLC、または ON-OFF コントロールを使用してバルブ操作を行う方法について説明します。リレー/PLC/DCS を使用した DCL アクチュエータの制御 リレーが電源(+)ラインを "ON "入力ターミナルに、電源(-)ラインを "OFF "入力ターミナルに切り替えると、アクチュエータはバルブを開きます。全開になるとアクチュエータは停止し、電動弁は開いたままになります。リレーが電源(+)[...]を切り替えると、電動弁は開いたままになります。

AC220V ON-OFFタイプアクチュエータ（電動弁）のしくみ

DCL AC220V ON-OFF形電動調節弁をパイプラインに設置する場合、リレー、ON-OFF制御、PLC（DCS）などを用いて制御し、流体の開閉を行うことができます。このガイドでは、DCL AC220V ON-OFF タイプ電動アクチュエータが、リレー、PLC、または ON-OFF 制御を使用してバルブ操作を行う方法について説明します。リレー/PLC/DCS を使用して DCL アクチュエータを制御する場合 L ラインがリレーを介して "OFF "入力ターミナルに切り替わると、アクチュエータはバルブを閉じます。完全に閉じるとアクチュエータは停止し、電動バルブは閉じたままになります。L ラインがリレーによって "ON "入力端子に切り替えられると、アクチュエータ [...] はバルブを閉じます。

アクチュエーターの種類と正しい選び方

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 heat protection in high-frequency regulation applications Best For: ✅ High-precision applications requiring strong controllability 2. Hydraulic Actuators Hydraulic actuators use hydraulic oil as the power source, converting hydraulic pressure into mechanical motion to drive the valve. Advantages: ✔ High load-bearing capacity Disadvantages: ✖ Poor controllability✖ Large and bulky system✖ Requires additional hydraulic stations and oil […]

How Humidity Reduces the Lifespan of Actuators (Electric Valves)?

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 short circuits. The process follows these steps: 1️⃣ Presence of an electric field between two conductors on an insulator.2️⃣ Electrolytic reaction occurs at the anode, releasing metal ions.3️⃣ Ions migrate under the influence of the electric field toward the cathode.4️⃣ Once enough ions accumulate at the cathode, a conductive bridge forms, causing a short circuit.

What Does the S2 Duty Cycle Mean in Actuators (Electric Valves)?

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 balance. The goal is to ensure that the motor does not overheat due to continuous operation. Definitions of Common Motor Duty Cycles: S1 (Continuous Duty Cycle): Operates at a constant load for a long enough period to reach thermal equilibrium. S2 (Short-Time Duty Cycle): Operates under a constant load for a set time, but not […]

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 […]
