Leak detection of vacuum titanium plating equipment
Release time:
2022-01-24
Typically, air leaks in the vacuum chamber of a vacuum titanium plating equipment occur at small holes on the chamber walls or at the joints in front of components. When the pumping system evacuates air, the pressure in the vacuum chamber decreases, and the pressure difference between the outside and inside causes gas to flow from the high-pressure outside to the low-pressure vacuum chamber, resulting in a decrease in vacuum. During the leak detection process of the vacuum titanium plating equipment, some issues need to be paid attention to in order to perform the leak detection work well.
Checking for leaks is a guarantee Vacuum titanium plating equipment A method for checking the vacuum degree, referred to as leak detection. The unevenness of the vacuum degree directly affects the coating effect, so leak detection is essential.
Usually, Vacuum titanium plating equipment Air leaks in the vacuum chamber occur at small holes on the chamber walls or at the joints in front of components. When the pumping system evacuates air, the pressure in the vacuum chamber decreases, and the pressure difference between the outside and inside causes gas to flow from the high-pressure outside to the low-pressure vacuum chamber, resulting in a decrease in vacuum. During the leak detection process of vacuum titanium plating equipment, some issues need to be noted in order to perform leak detection well.
1. Check whether the leak is actually a leak, because the workpiece data will generate varying degrees of gas after heating, which may be mistaken for gas flowing in from the outside. This is a false leak, and this situation should be eliminated.
2. Test the gas sealing function of the vacuum chamber of the vacuum titanium plating equipment to ensure that the airtight function meets the requirements.
3. Check the size, shape, orientation, and leakage rate of the leak hole, formulate a solution, and implement it.
4. Determine the leak detection rate and sensitivity of the inspection instrument, check the leakage situation over a wide range, prevent partial leakage from being overlooked, and improve the accuracy of leak detection.
5. Master the reaction time and elimination time of the leak detector, grasp the time well, and ensure that the leak detector is in place. If the time is short, the leak detection function will definitely be poor; if the time is long, it will waste leak detection gas and labor and electricity costs.
6. It is also necessary to prevent blockage of leaks. Sometimes due to operational errors, Vacuum titanium plating equipment During the leak detection process, some dust or liquid blocks the leak, thinking that there is no leak at this location. However, when these blockages are not blocked due to the progress of the internal and external pressure difference or other reasons, the leak still exists. Doing a good job of leak detection for vacuum titanium plating equipment is very important. There are many reasons for the decrease in vacuum. We should solve these reasons one by one to stabilize the coating effect.
