真空干燥箱使用說明書

Operating Instruction Manual of Vacuum Dry Box

一、適用范圍

本產品適用于廠礦企業(yè)、大專院校、科研單位等實驗室在真空條件下對物品進行干燥、加熱處理。在真空干燥箱內對物品真空加溫，真空干燥箱具有以下優(yōu)點：①可降低干燥溫度、縮短干燥時間。②避免一些物品在常規(guī)條件下加熱氧化、塵粒破壞以及加熱空氣殺死生物細胞。

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、結構特點

真空干燥箱外形為臥式，箱體采用好鋼板經沖壓、焊接制成。箱體表面噴塑處理。隔熱層采用硅酸鋁棉填充；箱門采用雙層鋼化玻璃門，可調節(jié)箱門的閉合松緊；工作室與玻璃門之間用模壓耐高溫硅橡膠密封圈，以保證箱門與工作室密封，大幅度提高了真空度。DZF型為方形工作室。

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、安裝調試

1、 安裝：真空干燥箱應放置在具有良好的通風條件，無強烈震動的室內，在本儀器周圍不可放有易然、易爆和腐蝕性氣體。

2、  調試：將箱門關閉并將門拉手旋緊，關閉回氣閥開啟真空閥，將箱體側面的導氣管用真空橡膠管與真空泵連接，接通真空泵電源，開始抽氣，當真空表指示值達到要求時。關閉真空閥和真空泵電源。此時箱內處于真空狀態(tài)。如無加熱功能真空干燥箱調試結束。

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..
