Deflectors
The first deflector (A) meets all the force from the sample flow, which can reach speeds of
up to 200 m/s, and is therefore exposed to hard wear. The deflector has a heavy ceramic
block (4) which is easy to replace by removing the bridge (1) and the cover plate (2). As
the service life varies greatly depending on rock conditions this block should be checked
every month or every 250 engine hours, until a replacement programme has been estab-
lished.
The second deflector (B) has a longer service life, but this also depends on rock condi-
tions.
The connection cover plate (C) becomes worn and is normally checked when replacing the
sample hose.
