Causes and solutions for problems such as not heating up and not running in vacuum atmosphere furnace

No matter what kind of machinery or equipment, in the process of use, it is inevitable that there will be problems causing the equipment to not run or other failures. Don’t panic at this time, look for solutions to common problems of the device on the Internet, refer to online tutorials for maintenance, and generally solve the problem. Today we are going to talk about solutions to two common problems in vacuum atmosphere furnaces.

Problem 1. The vacuum atmosphere furnace does not heat up. The reasons for this problem are roughly as follows:

1. Check whether the heating relay in the control box is closed, if not, check whether there is a problem with the circuit or the relay. If it is sucked in, there may be a problem with the thermometer on the drying tower, and the temperature display is abnormal.

Solution: Replace the defective part.

2. The heating element is faulty or short-circuited. This situation is generally manifested as: the power supply voltage is normal, the controller is working normally, and the ammeter has no display.

Solution: Check the heating element with a multimeter. If it is a short circuit, remove the source of the short circuit. If the heating element is damaged, you can check the resistance value, then the voltage regulator and the secondary voltage. If it is determined that the element is defective, you need to replace the heating element of the same specification. Generally, the one that is broken can be replaced, and it is not necessary to replace all of them.

Problem 2: The vacuum atmosphere furnace suddenly does not work during operation. The reasons for this problem may be the following two points.

1. The line is faulty or the component is out of order.

Solution: Check the circuit first, and repair it in time if it is found to be burnt or short-circuited. If there is no problem with the line, then check other parts, find which part is out of order, and just replace it.

2. If there is no cleaning for a long time, the area where the inner wall is thick, the cross-sectional area of ventilation is reduced, and the resistance of the air flow increases, so that the flue gas flow rate speeds up in the place with less fouling and causes the machine to stop.

Solution: Clean up the dirt on the inner wall in time. And it needs to be cleaned up regularly. Prevent this problem.

In the process of using the vacuum atmosphere furnace, no matter what problem you encounter, don’t panic first, find the cause first, and then find the solution. The reasons and solutions can generally be found on the Internet. If the problem cannot be solved, please contact the manufacturer immediately to solve it.
