The Use Specification
1、产品概述Summary
电动执行器用于控制0°~270°旋转的阀门及其他同类产品,如蝶阀、球阀、风门、挡板阀、旋塞阀、百叶阀等,可以广泛应用于石油、化工、水处理、船舶、造纸、电站、供热、楼宇自控、轻工等各行业中。它以380V/220V/110V交流电源为驱动电源,以4-20mA电流信号或0-10V DC 电压信号为控制信号,可使阀门运动到所需位置,实现其自动化控制,最大输出扭矩达4000N?M。
series electric actuator is used for controlling 0°~270° rotation of the valves and other similar products, such as butterfly valve, ball valve, damper, flapper valves, cock valves, etc. It’s widely used in petroleum, chemical, water treatment, shipping, paper making, power plants, heating, building auto-contorl, light industry and other industries. It drives by 380V/220V/110V AC power. Control signal is 4-20mA current signal or 0-10V DC voltage signal, enables move the valve to the desired position, achieving its automation, maximum output torque is up to 4000N2M..
2、性能特点Performance Features
2.1壳体Shell
壳体为硬质铝合金,经阳极氧化处理和聚酯粉末涂层,耐腐蚀性强,防护等级为IP67,NEMA4和6,并有IP68和防爆型供选择。
The shell is made of horniness aluminium alloy, pass through anodic oxidation treatment and polyester powder coating, so it has strong corrosion resistance. Protection grade is IP67, NEMA 4 AND 6, and optional IP68 type and explosion-proof model.
2.2电机Motor
全封闭式鼠笼式电机,体积小,扭矩大,惯性力小,绝缘等级为F级,内置过热保护开关,可防止损坏电机。 Fully enclosed Squirrel-cage motor, small volume, large torque, and small inertia force, F-class insulation rating, built-in thermal protection switch, avoiding damage the electric machinery.
2.3手动结构Manual Structure
手轮的设计保证安全可靠、省力、体积小。不通电时,扳动离合器手柄可进行手动操作。通电时,离合器自动复位。(注:在不通电的状况下,电动执行器将保持永久手动状态。)
The design of handwheel ensure safe, reliable, labor-saving, small volume. When it don’t have electricity, it can be manually operated by clutch handle. When it has electricity, the clutch will reset automatically.
2.4指示器Indicator
指示器安装在中心轴上,可以观察阀门位置。镜面采用凸透镜设计,不积水,观察更方便。
Indicator installs in the center axis, so it can observes the valve position. It adopts convex mirror design, no cumulate water, more convenient t
