Vacuum Drying Oven Must First Vacuum And Then Heat

Why Vacuum Drying Oven Should Be Vacuumed Firstly And Then Heated? Today OTS will clarify three important reason as follows:
1) If the heating and air evacuation procedures are followed, the heated air will be pumped by the vacuum pump, and the heat will inevitably be brought to the vacuum pump, which will cause the vacuum pump to rise too high, which may cause the vacuum pump efficiency to drop.
2) The heated gas is directed to a vacuum gauge, which generates a temperature rise. If the temperature rise exceeds the operating temperature range specified by the vacuum gauge, it may cause the vacuum pressure gauge to produce an indication error.
The correct method of use should be vacuumed and heated again. After the rated temperature is reached, appropriately pump it again if the degree of vacuum is found to have decreased, . This is advantageous for prolonging the service life of the equipment.
3) Vacuuming the work-piece into the vacuum chamber is to extract the gas components that can be pumped out of the pieceworker material. If you heat the pieceworker first, the gas will expand when exposed to heat. Due to the very good sealing of the vacuum chamber, the enormous pressure generated by the expanding gas may cause the tempered glass of observation window to burst. This is a potential danger. This danger can be avoided by following the procedure of vacuum first and then heating up.
