1. Before commissioning, we need to close the box door, tighten the handle of the door in place, then close the vent valve and open the vacuum valve. Of course, when you use it, the vacuum valve may be tight. You can rotate it with force.
When we connect the power supply of the vacuum pump, we need to start pumping. At this time, we need to close the vacuum valve first and then turn off the power supply of the vacuum pump, so as to prevent the oil of the vacuum pump from flowing back into the working room. At this time, the vacuum dryer is in a vacuum state. This is the test method of true air conditioning.
2. First of all, turn on the power of the vacuum dryer, then the power light will be on and self-test will be carried out, then it means that it has entered the state. To set the temperature of the vacuum dryer, this step is very important, so I want to spend a separate article to do it. When the temperature in the machine is set close to the specified temperature, then the heating begins to enter the PID regulation stage. At this time, the instrument will sometimes measure the temperature higher than the set temperature, and sometimes lower than the set temperature, which is a normal phenomenon.
When measuring the temperature, if it is close to or equal to the set temperature, it will almost enter the constant temperature state after 1 to 2 hours. If the required temperature is relatively low, we can use the method of secondary setting, so that it can enter the constant temperature state as soon as possible.
