Why is a vacuum test conducted on the system when the vehicle is first driven? What issues should be considered during testing?
The negative pressure system needs to undergo a vacuum test. The purpose is to further identify any issues in the system and test the performance of the vacuum pump.......
What location do you mean by vacuum test? Whether it is the location of the turbine’s air cooler or water cooler. When testing the vacuum level at such a position, it is important to fill it with water first; otherwise, adding water can lead to suspension issues. Check the condition of all pipelines and valves. Check whether the vacuum pressure is normal.
Vacuum pumping is performed during the commissioning of the turbine system.
Before performing the vacuum test, the system needs to be pressurized first to check for leaks.
For most chemical processing units, a pressure tightness test is generally carried out. However, for air separation units, vacuum airtightness testing is used. The reason is that these units operate at low pressures but at low temperatures; if the airtightness is poor, external air or gases from other pipelines can leak into adjacent units. Additionally, during vacuum testing, it is necessary to protect certain containers to prevent the equipment from deforming due to excessive vacuum levels. I guess that’s the reason.
