1994年以来,我省接受国外赠送的西门子公司产旧D1345型牙科综合治疗机20余台.由于甲方不提供任何资料,省内又没有相应机型可资参考,故安装调试中的困难比较多.据悉我国将不断引进这种二手设备.为此,谨将我们安装调试该设备时遇到的最为多见的典型问题介绍如下.一、电路1.供电该设备使用115V60Hz电源,冷光灯使用10V和12V电源(分低照度与高照度两档);若考虑升降和俯仰同时运动以及冷光灯
Since 1994, our province has received more than 20 sets of D1345 dental comprehensive treatment machines donated by Siemens abroad. Due to the fact that Party A does not provide any information, there are no corresponding models available for reference in the province, so the difficulties in installation and debugging are compared. It is reported that China will continue to introduce such second-hand equipment. To this end, we would like to introduce the most common typical problems that we encountered when installing and commissioning this equipment. I. Circuit 1. Power supply This equipment uses a 115V60Hz power supply and is used in cold light lamps. 10V and 12V power supply (in two levels of low and high illumination); if taking into account the simultaneous motion of lift and pitch and the cold light
