Adjustment procedure
＞
(For engine speed and pressure, see 1.2)
①
Adjust the length of the rod connecting speed regulator so that engine governor lever can be fully
pulled toward high speed side, with compressor kept stopping. (Making the rod length short,
engine speed increases.) If engine governor lever does not touch high speed side stopper, it is
impossible to get a determined engine speed at full load operation. But it is not necessary to
adjust unload operation speed.
②
Adjust this system so that when pressure exceeds 100psi (0.69MPa) by turning pressure
adjusting screw, speed regulator can start to function to lower engine RPM. (Tightening the
screw, the pressure rises, and loosening it, the pressure drops.)
IMPORTANT
：
Make sure to adjust engine speed in accordance with the above adjustment procedure so that engine
governor lever can touch high speed side stopper at full load operation. When separator receiver tank
pressure drops below
65.3psi (0.45MPa)
at unload operation with engine speed set lower than rated
set speed, discharge air temperature rises and it will result in a serious trouble.
