Mechanical Seal Test Bench

Api 682 iso 20149 section 10 3 1 4 1 additionally each assembled seal must be subjected to a quality assurance test.

Mechanical seal test bench.

Shaft seal bench validation. Tests of the prototype seal were performed on a special purpose test bench fig. This involves connecting the complete seal to a tank of pressurised air then measuring the pressure drop over five minutes to assess the leakage. Thus a test measurement system must be very flexible and versatile.

The purpose of this test is to prove that the cartridge has been assembled properly. However the test variously called the air test or integrity test is widely misunderstood. 2 process gas chamber. An average liquid leakage rate of less than 5 6 g h per pair of seal faces.

Testing determines the component s operational life expectancy. Scheme of the housing and a pneumatic and hydraulic system for the 30gsl a5 i 439 seal testing. The invention discloses a contact high speed mechanical seal testing device which comprises a bench a main test chamber a high speed torque gauge coupler a drive motorized spindle and a cooling and lubricating liquid supply system wherein the main test chamber the high speed torque gauge coupler and the drive motorized spindle are mounted on the bench. Its sliding faces in the assembled state.

This method used as a static leak test on large mechanical seals is usually unable to detect a leak as it is generally impossible to view the inside of the mechanical seal e g. A guide value for the detection sensitivity achieved by this method is 0 5 mbar 1 s. Nevertheless several factors are important for every seal test. Agitators are equipped with mechanical seals the test of a mechanical seal depends on its design and purpose.

Dynamic seal testing is used to test a seal design under a number of simulated and extreme operating conditions. Succession of individual tests implemented parameters and fig. The american petroleum institute standard for mechanical seals api 682 includes a test of the final cartridge assembly using pressurized air. 1 tested seal.
