Product application area:
-Temperature-vacuum drying of test objects within 24 hours at temperature up to 400 ° C and pressure not more than 1*10^-6 mm. Hg. according to OST 92-0019-78 after strength tests with distilled water or after washing with ethyl alcohol.
-Control of tightness of test objects at ambient temperature and pressure not more than 1*10^-6 mm Hg. by the method of "vacuumisation" in a vacuum chamber by comparison with a control leak.
The value of the ultimate residual pressure created in the vacuum chamber (without the test object) - not more than 5×10-7 mmHg.
The installation shall include the following units and assemblies:
- vacuum chamber with sliding frames;
- system of vacuum pumping of the chamber and test object;
- system of heating and temperature maintenance in the vacuum chamber and on the surface of the test object;
- helium leak detector;
- a set of helium control leaks;
- automated system for controlling the operating modes of the installation;
- in...
