Comay vacuum drying test chamber (oven)

1、 Purpose of vacuum drying test chamber

• Vacuum ovenDesigned and manufactured in accordance with the national professional standard JB/T5520-91,Widely used in research and application fields such as biochemistry, chemical pharmaceuticals, medical and health care, agricultural research, environmental protection, etc., for fast and efficient drying of powder drying, baking, and drying of heat sensitive, easily decomposable, easily oxidizable substances and complex component items

2、 Equipment model and specifications for vacuum drying test chamber

3、 Technical parameters of vacuum drying test chamber

4Vacuum drying test chamberStructural characteristics and configuration

• The box has a vertical shape, with a control panel on the upper part and a working room in the middle. The lower part is equipped with a vacuum pump and connecting pipes, and the bottom is equipped with four support feet or four wheels (two directional wheels and two universal wheels), making it easy to move;

• The inner liner of the box is made of universal SUS304 stainless steel plate, with a square shape,

• The shell is made of high-quality cold-rolled steel plate that has been acid washed, phosphated, and electrostatically sprayed with plastic. The intermediate insulation layer is filled with ultra-fine glass wool;

• The box door adopts a double-layer full glass door, with thickened tempered glass on the inner layer and explosion-proof glass on the outer layer. The door frame is equipped with springs that can adjust the tightness of the box door closure. A high-temperature resistant silicone rubber sealing ring is molded between the working room and the glass door to ensure the sealing of the box door and the working room, greatly improving the vacuum degree of the box.

• The box is equipped with two (or three) shelves, with heaters embedded in each shelf. The temperature of each shelf is controlled separately, and the heating process is short and the temperature rises quickly;

• The lower part is equipped with a direct connected vacuum pump and an electromagnetic vacuum belt inflation valve. Turning off the power switch of the vacuum pump can prevent the vacuum pump oil from entering the working chamber;

• The power switch, vacuum pump switch, microcomputer intelligent temperature controller, vacuum gauge, anti air valve and other controllers and instrument switches are all installed on the panel in front of the box. The microcomputer intelligent temperature controller adopts self-tuning PID technology, which has the characteristics of fast temperature control, fast response, small overshoot, and high accuracy compared to traditional PID control. The set temperature and box temperature are both digitally displayed, with upper limit tracking alarm function. The parameter can be set with a touch of the button, and the operation is convenient.

5、 Vacuum drying test chamberSafety protection device

• When the control system detects the action of the following protective devices (single row), it should be able to automatically cut off the entire system and give an alarm prompt.

• Over temperature protection device

• Reverse phase and phase loss protection device

• Non fuse switch overload protection

• Overload protection for blower motor

• Heater short circuit

• Line fuses and fully sheathed terminals
