牙科用电动振荡器是口腔修复科技工制作铸造模型用的一种电动器械,这种电动器械可消除铸模中的气泡,从而保证铸件的质量.这种电动振荡器由于使用寿命长,如得不到及时维修在使用中会产生很大噪声,给工作人员带来干扰和烦恼,有些维修人员由于对其工作原理不了解,而束手无策.其实牙科用电动振荡器工作原理很简单,它是由一组电磁铁及其附件组成.电磁铁定铁芯固定于器械底盘上,在动铁芯上固定着铸模载体,载体四角由四块柱形弹力橡胶支撑,使定铁芯上的动铁芯与其保持适当距离,电磁线圈就绕缠固定于“山”形铁芯中间 The dental electric oscillator is a kind of electric instrument used by dental prosessing technology to make a casting model. This kind of electric instrument can eliminate the bubbles in the mold and thus ensure the quality of the casting. This type of electric oscillator has a long service life, if not To the timely maintenance in use will produce a lot of noise, to the staff to bring interference and trouble, and some maintenance personnel because they do not understand the working principle and helpless. In fact, the working principle of dental electric oscillator is very simple, it is Group electromagnet and its accessories. The electromagnet fixed iron core is fixed on the chassis of the equipment. The mold carrier is fixed on the moving iron core. The four corners of the carrier are supported by four column-shaped elastic rubbers to keep the moving iron core on the fixed iron core. Proper distance, the electromagnetic coil is wrapped around the middle of the “mountain” core
