电火花计时器是电磁打点计时器的更新换代产品,具有操作简单、准确性高、可靠性好、使用安全的特点。电火花计时器是利用火花放电在纸带上打出点迹的计时仪器,使用时将墨粉纸盘套在纸盘轴上,并夹在两条纸带之间,当接通220V 电源,按下开关,计时器发出的脉冲电流经接正极的放电针,墨粉纸盘到接负极的纸盘轴,产生火花放电,于是在运动的纸带上打出一列点迹,当电源频率是50Hz时它每各0.02s 打一次点。使用这种计时器工作时,纸带运动时受到的阻
The electric spark timer is the replacement product of the electromagnetic striking timer. It has the characteristics of simple operation, high accuracy, good reliability, and safe use. The spark timer is a timing device that uses spark discharge to make dots on the paper tape. When it is used, the paper tray of the toner is placed on the paper tray shaft and sandwiched between two paper tapes. When the 220V power supply is turned on, press Under the switch, the pulse current from the timer is connected to the positive discharge needle, and the toner paper tray is connected to the negative paper tray shaft to generate spark discharge, so a string of dots is struck on the moving paper tape when the power frequency is 50 Hz. It hits once every 0.02s. When working with this timer, the tape is blocked during movement
