电子技术不断地发展,对各种仪器的自控要求越来越高。防高温是 X 线管球的重要保护措施之一。特别是夏季工作量大,X 线管温升快,如稍有疏忽,可致 X 线管损毁。另外,暗室洗像液的恒温是保证 X 线照片质量的重要因素之一。我们设计和自制了“一机两用”的装置。介绍如下。一、自制过程(一)应用元件:变压器1个,硅桥1个,电解电容器1个,高灵敏继电器1个,二极管1个,三极管2个,电阻5个,300Ω热敏电阻1个。
The continuous development of electronic technology, automatic control requirements for a variety of instruments is getting higher and higher. Anti-heat is one of the important protection measures of X-ray tube. Especially in summer workload, X-ray tube temperature rise faster, such as a slight negligence, can cause X-ray tube damage. In addition, the constant temperature darkroom washing liquid is one of the important factors to ensure the quality of X-ray photos. We designed and made a “dual-use ” device. Introduced as follows. First, the self-made process (a) the application of components: a transformer, a silicon bridge, electrolytic capacitors 1, a highly sensitive relay, a diode, transistor 2, resistance 5, 300Ω thermistor.
