Leak testing method, esp. for hydraulic systems - involves filling test vol. and test device partial vol. with test liquid, changing test vol. and measuring resulting press. step

摘要

A test vol. contg. at least the vol. of the hollow chamber to be tested and the partial vol. of the leak testing device relevant to testing are filled with a test liquid and with air at a defined press., and the test vol. is closed. The air vol. component in the test vol. is determined by changing the test vol. and measuring the resulting press. step. As required, the air vol. component is corrected until a defined press. step is produced. The press. drop in the test vol. is measured and evaluated. USE/ADVANTAGE - Can be used with low test press., is insensitive to seal tolerances and enables reliable, rapid testing without visual or vol. monitoring of test medium.
