Vacuum furnaces generally have more leakage faults in spring and autumn

        Vacuum furnaces generally have more leakage faults in spring and autumn, so how to solve them? Let's take a look at the following with the heat treatment electric furnace manufacturer:

        The vacuum furnace that has been idle for a long time is more prone to leakage failures when the vacuum furnace is only used. Vacuum leak detection is required at this time. Vacuum leak detection is generally done once a month to measure the pressure rise rate (at room temperature, close all vacuum valves, stop the vacuum system, read a number after 10min, read a number after 1h, two The difference between the numbers is the value of the pressure rise rate), and grasp the change trend of equipment leakage.

        In the vacuum system leak detection, in addition to temporary emergency maintenance with vacuum slurry plugging, a helium mass spectrometer leak detector can be used for vacuum leak detection with a helium mass spectrometer leak detector. If there is no helium mass spectrometer leak detector, a medical needle can be used to suck acetone or ether. Go to the suspected leakage point and observe whether there is any change in the vacuum gauge reading. Blind plates with holes for inserting vacuum silicon tubes can also be made to block vacuum pipelines in sections for leak detection. Repair after finding the leakage point (usually the seal ring is more aging), and regularly check the slide valve pump, roots pump, maintenance pump, and diffusion pump oil of the vacuum furnace. If the oil is found to be emulsified with water and the vacuum drops, replace the above 4 For pump oil, check the oil level and oil quality once a week. Diffusion pump oil The oil diffusion pump has carbon deposits and can be cleaned by chemical pickling.
