Fig. 90: Leak check induction furnace
–
Open the furnace and check again. If the pressure decreases when checking with open
furnace, then the leakage is not in the furnace area but elsewhere in the analyzer.
Most probable reasons:
–
An infrared path is not seal, for example due to an infrared window with a crack or with
not properly sealing glue.
–
The lower flow meter may be not seal due to a crack.
2.
Leakage outside the furnace area:
Localizing a leakage outside the furnace area with open furnace in induction
mode:
–
When pressing the button (2), the gauge (3) shows a pressure drop lasting for one minute
(see details above) while the furnace is open, then localize the leakage, according to the
sequence below.
Keep the furnace opened, squeeze the following tubes tightly, while pressing and holding the
button (2). If there is no pressure drop any more when squeezing the corresponding tube, the
leakage is in the place shown in the table below:
