| | GYD系列气压自动开关 GYD Double-stage double-speed starter | 一、用途 Application
当空气压缩机工作时，压缩空气从储气罐进入气压自动开关。气压自动开关的闭合与断开是按预先设定的压力而动作。空气压缩机正常运转时，开关处于闭合状态，当储存气压力达到预定压力的上限时，压缩空气经橡皮顶动顶针，能过跳簧带动跳板，从而使胶木座内动触头与静触头分离开，达到切断控制电路，使电动机停止转动。当储存罐气压降到所标气压下限时，重新起跳，使电路接能中而开始工作，气压自动开关上设有放空阀，当跳板跳动时，压下顶杆，使放空阀打开，达到排气目的，为第二次工作时减轻电动机起动负荷。
After the motor runs,the press ure is produced and directly gets into the switch ,under the action of sensing film,the thrust is developed,the pressure spring with it makes the driving plat move up to drive the spring board,and actuate the jumper spring to fast separate the moving contact from the fixed contact with the help of elastic force,so as to cut off the power,the motor will stop running immediately. |
