Performance of vacuum brazing furnace

The quality of the vacuum brazing furnace depends on the performance of the true air unit. A vacuum pump needs to be always careful not to think that “you never shut down, it will run forever.” If the vacuum unit is maintained at that time, it will be economical to shut down on weekends and holidays. Otherwise, if the weekend is still empty, the mechanical pump will be stuck and will be difficult to start.

The results of our experiments show that this method can be used to save a lot of electricity. Due to the lack of cooling water or overheating, the mechanical pump overheats and makes noise. It’s best to keep the water temperature 140. (60 ~ 150 F a 6 ℃), the use of portable devices to pump oil filter once a week, check the oil level and take the sample, check the oil quality by feeling and appearance.

In the last few years, we have found that mechanical pumps are more economical to use high quality oil. High quality oil costs more than three times as much as general industrial oil, while keeping the pump clean is five times longer. A live door and spring should be replaced every three months. Stainless steel springs last longer.
