Tabletop vacuum drying chamber structure overview and working principle

DF-6000 series vacuum drying box except for 6090, 6210 type is vertical, the rest are desktop structure
.

The vacuum box is composed
of four parts: the box, the inner tank, the vacuum system and the temperature control system.

The cabinet is made of thin sheets, the surface is sprayed and treated, and the colors are bright
.

The inner tank is made
of general galvanized steel plate or stainless steel plate.

The inner cavity is shaped as a square
with the inner corner of a semicircular arc.

Fill the inner and outer boxes with fine glass wool as thermal insulation materials; The middle of the door adopts a double-layer glass structure, which is convenient for observing the dried items in the box; In the inner side of the door is equipped with a thick tempered glass, while the use of long cylindrical door buckle, so that the use of adjusting the distance between the door buckle and tempered glass, so that the door can be tightly pressed after closing the rubber seal, in order to ensure that the vacuum level does not leak
.

(Note: The rubber seal is not oil resistant!) The vacuum extraction system is composed of
a vacuum pump, a vacuum gauge and a vacuum valve (vacuum valve for solenoid valve type 6090, 6210), and a vent valve.

According to the needs of the user, the drying filter (apparatus) or the intake valve can be added, and the vacuum pump of the 6090 and 6210 types is included with the vacuum pump and other types of vacuum boxes
.

Conversely, the power tube has no electric power output heater and does not heat
.

The thermometer has PID adjustment output characteristics, adjustable electrical power output size, error correction of measuring temperature, timing control and other functions and temperature light and automatic cut-off deviation alarm function
.

In addition to the 6030B, 6050B type using inner tank bundle heating, other types of heaters are installed in the shelf, of which the temperature of 6090, 6210 type shelf is controlled by two and three thermometers alone
