真空泵真空干燥箱利用真空泵进行抽气抽湿,使工作室内形成真空状态,降低水的沸点,加快干燥的速度。有干燥物品速度快、污染小、不对被干燥物品的内在质量造成破坏的优点。

带真空泵真空干燥箱的使用要点

1.若带真空泵真空干燥箱长期不用,将露在外面的电镀件擦净后涂上中性油脂,以防腐蚀,并套上塑料薄膜防尘罩,放置于干燥的室内,以免电器元件受潮损坏,影响使用。

2.外壳必须有效接地,以保证使用安全。

3.应经常保持清洁。箱门玻璃切忌用有反应的化学溶液擦拭,应用松软棉布擦拭。

4.应在相对湿度≤85%RH,周围无腐蚀性气体、无强烈震动源及强电磁场存在的环境中使用。

5.除维修外,不能拆开箱体盖以免损坏电器控制系统。

6.工作室无防爆、防腐蚀等处理,不得放易然、易爆、易产生腐蚀性气体的物品进行干燥。

7.放气阀橡皮塞若旋转困难,可在内涂上适量油脂润滑。

8.真空泵不能长时期工作,因此当真空度达到干燥物品要求时,应先关闭真空阀,再关闭真空泵电源,待真空度小于干燥物品要求时,再打开真空阀及真空泵电源,继续抽真空,这样可延长真空泵使用寿命。

9.经多次使用后,会产生不能抽真空的现象,此时应更换门封条或调整箱体上的门扣伸出距离来解决。当真空箱干燥温度高于200℃时,会产生慢漏气现象,此时拆开箱体背后盖板用内六角扳手拧松加热器底座,调换密封圈或拧紧加热器底座来解决。

10.干燥的物品如潮湿,则在真空箱与真空泵之间加入过滤器,防止潮湿气体进入真空泵,造成真空泵故障。
