真空干燥箱使用说明书

Operating Instruction Manual of Vacuum Dry Box

一、适用范围

本产品适用于厂矿企业、大专院校、科研单位等实验室在真空条件下对物品进行干燥、加热处理。在真空干燥箱内对物品真空加温，真空干燥箱具有以下优点：①可降低干燥温度、缩短干燥时间。②避免一些物品在常规条件下加热氧化、尘粒破坏以及加热空气杀死生物细胞。

Ⅰ. Scope of application

It is suitable for drying and heating articles in vacuum conditions in the laboratories of industrial and mining enterprises, colleges and universities and R＆D institutions etc. Make vacuum heating for articles in vacuum dry box. The vacuum dry box has following advantages:①Could reduce the drying temperature, shorten the drying time.②Avoid some articles heated oxide, dust particle damage and the heating air kills the biological cells.

二、结构特点

真空干燥箱外形为卧式，箱体采用好钢板经冲压、焊接制成。箱体表面喷塑处理。隔热层采用硅酸铝棉填充；箱门采用双层钢化玻璃门，可调节箱门的闭合松紧；工作室与玻璃门之间用模压耐高温硅橡胶密封圈，以保证箱门与工作室密封，大幅度提高了真空度。DZF型为方形工作室。

Ⅱ. Structure characteristics

The shape of vacuum dry box is horizontal type. The box body is make of high-quality steel plate with pressing and welding processing. The surface of box adopts plastic spraying treatment. Thermalprotective coating filled by alumina silica wool. The box door is made od double toughened glass, whech could regulate the open and close, degree of tightness of box door. The formed high-temperature resistance silicon rubber sealing washer used between work room and glass door for ensuring sealing between the box door and work room, which improved the vacuum degree greatly. DZF type has square workroom..

三、安装调试

1、 安装：真空干燥箱应放置在具有良好的通风条件，无强烈震动的室内，在本仪器周围不可放有易然、易爆和腐蚀性气体。

2、  调试：将箱门关闭并将门拉手旋紧，关闭回气阀开启真空阀，将箱体侧面的导气管用真空橡胶管与真空泵连接，接通真空泵电源，开始抽气，当真空表指示值达到要求时。关闭真空阀和真空泵电源。此时箱内处于真空状态。如无加热功能真空干燥箱调试结束。

Ⅲ. Installation and debugging

1.Installation: Put the vacuum dry box at the place in the room with good air conditions and without succession. There should no inflammable, explosive and corrosive air in the surroundings od instrument.

2.Debugging

Close the box door and screw the handle. Close the return-air valve and open vacuum valve, connect the airway at side of box body with vacuum pump by vacuum rubber pipe, switch on the power of vacuum pump, begin to exhaust air. When the indicating value of vacuum meter reaches to required value, close the vacuum valve and switch of vacuum pump. At this time, it has vacuum condition in the box. It there is no heating function, the debugging of cacuum dry box is end..
