Installation and debugging steps and points for attention of square vacuum drying oven

Square vacuum drying box is suitable for high temperature treatment of non oxidation drying, defoaming, solidification, welding, annealing, etc in semiconductor, electronic products, hardware products, medical and health care, instruments and meters, factories, colleges and universities, scientific research and other departments The structure of the box is also complex; if it is operated by unprofessional personnel, it will be easy to cause accidents; therefore, I will share with you the installation and debugging steps and key points of attention of the square vacuum drying box: the installation and debugging steps of the square vacuum drying box are divided into: 1 Installation: the box shall be placed in a room with good ventilation conditions and no strong vibration, and no inflammable and explosive articles shall be placed around it 2 Commissioning: (1) close the box door and tighten the handle, close the vent valve and open the vacuum valve (2) Connect the air guide pipe on the side of the square vacuum drying box with the vacuum pump with the vacuum rubber pipe, connect the power supply of the vacuum pump, and start pumping When the indicator value of the vacuum gauge reaches - 0.1MPa, turn off the power supply of the vacuum pump and the vacuum pump, and the box is in the vacuum state at this time If there is no heating requirement, the commissioning of the square vacuum drying box is completed 3 If the set temperature is 120 ℃, the heating indicator will be on, and start to enter the heating and warming state When the display temperature is close to the set temperature, the heating indicator will be on and off repeatedly, and the temperature control will enter the constant temperature state, which means the operation is normal The precautions for the use of the square vacuum drying oven are as follows: 1 The inner tank of the oven and the surface of the equipment shall be wiped frequently to keep clean and increase the transparency of the glass Do not wipe the outer surface with acid, alkali or other corrosive solution 2 When in use, the temperature in the test box will rise to a very high level, so there is a requirement for the sample Inflammable and explosive materials must not be put into the box, and inflammable and volatile chemicals must not be put into the box 3 In case of any abnormality, smell, smoke, etc in the use process, please turn off the power immediately The user shall not repair blindly, but inform the repair Department of the company, and the professional shall check and repair (there will be peculiar smell and a small amount of smoke when the new machine is started for the first time This is a normal phenomenon Please observe it once or twice If this phenomenon occurs all the time, please contact the editor to deal with it.) 4 If the square vacuum drying oven is not used for a long time, the power cord shall be unplugged to prevent the equipment from damaging the drain pipe, and it shall be operated regularly (generally in the first quarter) for 2-3 days according to the use conditions to drive out the moisture in the electrical part and avoid damaging the relevant devices.
