美国产ＶＭ—Ｄ型银汞搅合器应用于口腔科银汞合金填料的搅合配制，由于原料配制特点，搅合时间及振荡频率对于合金填料的制备强度有直接的影响，对于该机的故障维修首先应根据其电路工作原理及检修要点进行检测才能少走弯路，取得事半功倍的效果。下面首先简介一下该机工作原
The American-made VM-D amalgamator is used in the mixing of dental amalgam fillers. Due to the characteristics of raw material preparation, the stirring time and oscillation frequency have a direct impact on the strength of the alloy filler. Fault repair should be based on the circuit work principle and the main points of inspection to detect and avoid detours and achieve a multiplier effect. The following brief introduction to the original work of the aircraft
