TEE TEST PROCEDURE FOR HYDRAULIC SYSTEM (CONT)
(Sheet 10 of 27)
Must be down to at least 100 psi (70.3 kgs/sq.
5. Oil flow rate (gpm)
The base flow rate of the system must be the
same as the low pressure flow of the hydraulic
pump. Because there will be minimum leakage
in the control valves, lines and cylinder
packings at 100 psi (70.3 kgs/sq. meter), the
base flow rate can be used to find the flow
differential (flow loss) in Tests 4 through 7.
Keep system constant under each test
TESTS 4 THRU 7
Operate in each position.
Run at 2000 (700) rpm.
Manual control valve
Close until system pressure is 1000 psi (703
Oil flow rate
Record for each test.
