真空乳化机是日化、食品、制药等行业常见的一种操作单元，将两种不相容的液体转变成均匀分布的液液分散体系的设备。使用真空乳化机需要注意哪些事项？有着20多年乳化机生产制造研发经验的金宗企业来告诉你。
1、经常检查之上密封装置油盆之中的密封液（甘油）。液位应高于静环和动环的接触密封面。如果您是自动升降溶解罐的用户，应注意液压油的液位和液压密封圈及弹簧装置。
2、锅之内无料、无水时，不要启动均质器，以免损坏。（在启动均质器以前，必须打开机械密封，使冷却水循环）。
3、定期检查和更换摆线针轮减速机之内的润滑脂。
4、溶解锅之内无物料时，不要启动搅拌装置，以免损坏搅拌器。
5、设备在使用过程之中，用户必须定期送至有关部门进行核查。调整个安全阀及开启工作压力，确保设备安全使用。
6、设备必须有可靠的接地零线。
7、应定期对真空泵水箱进行检查，保持水位比真空泵接口高30 mm左右。真空系统经过长时间的抽真空之后，缓冲罐底部堆积了大量的产品残留物。每次操作之后，应打开排放阀，清除残留物。
8、对于正压出料的机器，在盖子升起以前，必须将夹紧螺丝放回夹紧螺丝架之上，否则机器无法升起。
9、其他检查项目：如果吸水管变硬、老化，会出现各种故障，应定期、每月检查吸水管的弹性和侵蚀情况。

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)??
