一、用途该仪器为解决过去人工进行快门耐久次数试验,劳动强度大,耗费人力和时间多而设计。仪器可同时对三只快门和一架整机进行测试。二、结构仪器分为机械和电气两部分。机械部分传动由可控硅控制伺服电机带动凸轮拨动快门及按钮释放。无级调速,在调节上较为方便。记数部分数码显示,带有各只快门的故障报警电路。仪器采用光电控制原理,由记忆电 First, the use of The instrument to solve the past manual shutter durability test, labor-intensive, labor-intensive and time-consuming design. The instrument can test three shutters and one complete machine at the same time. Second, the structure of the instrument is divided into mechanical and electrical two parts. Mechanical part of the drive by the SCR control servo motor driven cam dial shutter and button release. Stepless speed regulation is more convenient. Counting part of the digital display, with each shutter fault alarm circuit. The instrument uses photoelectric control principle, by memory
