Vetter Leak sealers - Manual (Page 27)

Page 27/39
A leak in a container or tank is a weak point. Therefore avoid any
additional damage by filling the leak sealer so that no more liquid
or gas escapes. This can be the case at a point lower than the ma-
ximum permissible operating pressure.
9 The attached vacuum leak draining bag is to be continually
monitored.
9 Always make certain that there is sufficient air.
9 After termination of operation, the air supply only needs to be
closed (close the output valve on the pressure regulator).
9 After releasing the vacuum, the bag is detached from the wall
of the tank.
9 Do not let the bag fall otherwise this could damage it.
Example of the air requirement
Compressed air bottle 6 l/300 bar
Input pressure Vacuum Operational time
2 bar 0.15 bar 20 min
3 bar 0.25 bar 14 min
4 bar 0.38 bar 10 min
Minimum power of the compressor: 200 l / min. at 4 bar
9 Use a Y-distributor when using a number of compressed air
bottles.
9 The vacuum power of the bag can also be increased before
operation by wetting the sealing lip with soap or water.
10.4 After operation
9 Check the bag and accessories after each operation to ensure
completeness and perfect condition.
9 If necessary, clean the bag and accessories with warm soapy
water and then with clear water.
9 Dry the bag and accessories at normal room temperature.
9 Inspect for tears, cuts or punctures.
9 Inspect the suction cups for damage, especially in the edge
area.
9 Inspect the controller for any damage and test the safety val-
ve to ensure perfect activation.
