3 Vacuum Leak Detection Tips 3 Vacuum Leak Detection Tips
Most appliances are made out of metal or plastic materials, so vacuum leak detection is important. No matter what material is used, continuous usage over a period of time makes them susceptible to leakage. A leakage can be very small in size, but can hamper the function of the entire machine in a big way. So it is important to find out the leakage in a quick and efficient manner. There are several ways of fixing the leaks and here we shall discuss some well known, tried and tested methods
Tip 1 - Change in Pressure
The leaked pipe is sprayed with a solvent. The solvent causes the pressure in the affected area to rise when it comes in contact with the leak. This change can help a technician to detect the location and the size of the leak.
Tip 2 - Overpressure Method
In an over pressure method the material to be tested is filled with liquid or gas at high pressure. Gas or liquid being flexible in nature tends to escape from the leakage, and the exact spot of leakage can be identified easily.
Tip 3 - Halogen Leak Detector
These are primarily used to detect leaks in refrigeration units, where the unit is filled with halogen. A halogen leak detector checks the sample of the air near the unit and detects a leak if it is found to contain halogen in it.
Besides these usual methods, other methods like the spark coil technique, Dye penetration and radioisotope method are used to detect leak very fine leaks in various equipments.
