MEASUREMENT AND INSPECTION OF VIBRATOR CIRCUIT PRESSURE
6-2. Inspection
If the measurement results indicate the pressure
values deviating from the maximum standard
vibration pressure setting, conduct an inspection
in accordance with the procedure described
below.
Since the high-pressure relief valve is a fixed
type, the pressure setting cannot be adjusted.
①
Remove the high-pressure relief valve (2-3 or
2-4).
High-pressure relief valve (2-3)
: Low-amplitude side
High-pressure relief valve (2-4)
: High-amplitude side
②
Check the removed high-pressure relief valve
for dust and other abnormalities.
③
If dust is present, disassemble and clean the
high-pressure relief valve.
④
I f , a f t e r d i s a s s e m b l y a n d c l e a n i n g , y o u
remeasure the pressure and find that it deviates
from the maximum standard vibration pressure
setting, replace the high-pressure relief valve.
⑤
After the inspection is completed, measure the
pressure again. Confirm whether the pressure
rises to the maximum standard vibration
pressure setting range.
High-pressure relief valves (2-3 and 2-4)
: 176 N·m (130 lbf
·
ft)
Carefully disassemble and reassemble after
taking steps to prevent foreign matter from
getting in.
Numbers such as 2-3 and 2-4 in the illustration
correspond to the leader numbers in the
propulsion pump drawing in section 2-3,
“Hydraulic equipment specifications” (page
4-007.)
