7.5.7.1
Checking the lubricant reservoir for leakage
After reassembly, the mechanical seal area/lubricant reservoir must be tested for
leakage. The lubricant filler opening is used for leak testing.
Observe the following values for leak testing:
▪
Test medium: compressed air
▪
Test pressure: max. 14.5 psi [1 bar]
▪
Test period: 5 minutes
p
14.5 psi
(1 bar)
Fig. 27: Screwing in the testing device
1.
Unscrew and remove the screw plug and joint ring of the lubricant reservoir.
2.
Screw the testing device tightly into the lubricant filler opening.
3.
Carry out the leak test with the values specified above.
The pressure must not drop during the test period.
If the pressure does drop, check the seals and screwed connections.
Then perform another leak test.
4.
If the leak test has been successful, fill in the lubricant.
7.5.7.2
