1. 反应釜主密封口采用A型的双线密封，其余密封点均采用圆弧面与平面、圆弧面与圆弧面的线接触的密封形式，依靠接触面的高精度和光洁度，达到良好的密封效果。
2. 釜盖上装有压力表，爆破膜安全装置，汽液相阀，温度传感器等，便于随时了解釜内的反应情况，调节釜内的介质比例，并确保安全运行。
3. 隔套上部装有测速线圈，连成一体的搅拌器与内磁环旋转时，测速线圈便产生感应电动势，该电势与搅拌转速相应，该电势传递到转速表上，便可显示出搅拌转速。
4. 轴承采用不锈钢轴承或高强电化石墨，耐摩损，且维修周期长。
5. 磁联轴器与釜盖间装有冷却水套，当操作温度较高时应通冷却水，以及磁钢温度太高而退磁。
6. 联轴器主要由具有很强磁力的一对内、外磁环组成，中间有承压的隔套。搅拌器由伺服电机通过联轴器驱动。控制伺服电机的转速，便可达到控制搅拌转速的目的。
7. 釜体外装有桶型碳化硅炉芯，电炉丝穿于炉芯中，其端头由炉壳侧下部穿出，通过接线螺柱，橡套电缆与控制器相连。
8.釜体、釜盖采用不锈钢加工制成，釜体通过螺纹与法兰联接，釜盖为正体平板盖，两者由周向均布的主螺栓、螺母紧固联接。

Tip: If the failing expression is known to be legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
