Testing and Adjustment
CLG835H
Pressure test of work hydraulic system
Bucket cylinder test
Temperature of test oil: 50±5°C\ 122±41°F
Test items
Test method
Criterion
Commissioning
Adjust the pressure of test system to make the
tested hydraulic cylinder start without load con-
dition and conduct full stroke reciprocating
motion for more than 3 times to bleed the air
from the hydraulic cylinder.
The hydraulic cylinder operates smoothly without
being stuck.
Pressure tight
test
Stop the tested hydraulic cylinder piston at both
ends of stroke respectively (single-acting
hydraulic cylinder stopped at the limit position of
stroke), then apply 1.5 times rated pressure of
oil to the working chamber and keep for 10s.
External leakage and damaged parts are not
allowed.
Internal leak-
age test
Supply oil to the working chamber of tested
hydraulic cylinder, then increase the pressure to
the working pressure, measure the oil leakage
at port of small cavity for 2min.
Internal leakage
≤
0.30ml/min\ 0.000079US gpm
Stroke test
Stop the tested hydraulic cylinder piston at the
limit positions at both ends of stroke respec-
tively, then measure its stroke length.
