Description :

　　1Constant temperature vacuum industrial ovenBox specifications

　　Box structure: connected type, with the vacuum pump placed at the bottom of the machine;

　　Partition layer: divided into two layers, with two distribution boards that can be easily removed;

　　Panel installation: The control panel is installed under the machine (as shown in the equipment appearance diagram);

　　Door opening method: single from right to left opening;

　　Visual window: with a visual window on the door, size W250 × H300mm;

　　The material of the inner box is 304 # stainless steel industrial plate; Strengthen the treatment of the inner box and vacuum it without deformation;

　　The outer box material is cold-rolled steel plate, with a thickness of 1.2mm and a surface treated with baking paint;

　　Install brake adjustable casters that can be pushed freely;

　　IILaboratory vacuum boxTemperature control system

　　Temperature range: Room temperature+30 ℃~300 ℃

　　Control accuracy: ± 0.5 ℃

　　Display accuracy: 0.1 ℃

　　Temperature uniformity inside the box: ± 5 ℃% (empty box test without vacuum)

　　Heating rate: RT → 100 ℃ (about 30 minutes), 200 ℃ (about 45 minutes)

　　IIIVacuum nitrogen ovenvacuum system

　　Vacuum degree: 0~-101KPa

　　Vacuum pressure leakage rate: approximately 0.8KPa per hour

　　Using high sealing silicone sealing strips to ensure the sealing of the entire machine;

　　Using a digital display vacuum gauge to directly display the vacuum degree inside the box, allowing you to instantly understand the vacuum status inside the box. The vacuum degree reaches 0-0.1Mpa (i.e. 100pa vacuum degree)

　　4、 Nitrogen filling device

　　1. Pressure regulating valve: controls the nitrogen pressure, and under normal use, the nitrogen pressure is adjusted to around 2.5 kilograms;

　　2. Panel flowmeter: controls the size of nitrogen entering the box, with a range of 10L/min-60Lmin;

　　3. The nitrogen pipeline enters directly behind the box, and an 8mm quick plug gas pipe interface is reserved at the pressure regulating valve;

　　4. Note: Nitrogen is provided by the user.

　　The reason for first vacuuming and then heating up the vacuum drying oven

　　1) The purpose of placing the workpiece in a vacuum box for vacuuming is to remove any gas components that can be extracted from the material of the workpiece. If the workpiece is heated first, the gas will expand when exposed to heat. Due to the excellent sealing of the vacuum box, the enormous pressure generated by the expanding gas may cause the tempered glass of the observation window to burst. This is a potential danger. By following the procedure of vacuuming first and then heating up, this danger can be avoided.

　　2) If the procedure of heating up first and then vacuuming is followed, when the heated air is pumped out by the vacuum pump, the heat will inevitably be carried to the vacuum pump, resulting in a high temperature rise of the vacuum pump and a possible decrease in its efficiency.

　　3) The heated gas is directed towards the vacuum pressure gauge, which will generate a temperature rise. If the temperature rise exceeds the specified operating temperature range of the vacuum pressure gauge, it may cause indication errors in the vacuum pressure gauge.

　　The correct usage method should first evacuate and then heat up. When the rated temperature is reached and the vacuum degree is found to have decreased, add some more suction appropriately. This is beneficial for extending the service life of the equipment.
