approval. Any deficiency or maladjustment disclosed by the tests shall be
corrected immediately and the test repeated until satisfactory results are
obtained. No subsequent tests will be permitted until all preceding tests
have been completed satisfactorily. Upon completion of the final
acceptance tests, the Contractor shall furnish a written statement that the
hydraulic power system has been field tested and meets all operational
requirements.
3.3.3.1
Initial Start-Up
The hydraulic reservoir shall be inspected to ensure that the fluid is at
the proper level. The accumulator precharge pressure shall be inspected
and adjusted to the specified value. The hydraulic pumps shall be test
started using [both] the controls at the control console [and the remote
controls]. The [pump] [pumps] shall be inspected for proper operation and
discharge pressure. The discharge pressure of [the] [each] pump shall be
read and recorded. The pressure relief [valve] [valves] shall be adjusted
to limit the system pressure to the specified value. The unloading [valve]
[valves] shall be adjusted to unload the pumps to the reservoir when the
accumulator has been charged to the specified pressure or if the control
valves are not actuated. The hydraulic lines and components which are
under pressure shall be inspected for evidence of leakage.
3.3.3.2
Combined System Tests
Tests and inspections of the hydraulic power system shall be performed
concurrently with the testing specified under other sections of these
specifications which test the mechanism operated by the hydraulic system.
The hydraulic system shall be tested by operating the mechanism through a
minimum of four complete cycles. During each test operation, the hydraulic
lines and components shall be inspected for evidence of leakage. The
pressure in the supply and return lines for each direction of operation
shall be read and recorded. Response of components to operation of
applicable controls shall be inspected to ensure that all connections have
been made properly. [Flow control valves shall be checked and adjusted as
required to conform to indicated operating time requirements.] [Sequence
valves shall be inspected and adjusted as required to obtain the indicated
sequence of operation.] [Chokes in pilot circuits of pilot-operated valves
shall be adjusted to obtain smooth, shock-free operation.]
3.3.3.3
Test Reports
**************************************************************************
NOTE: Edit the following data to be reported as
required.
**************************************************************************
The Contractor shall prepare and complete test reports showing in detail
the results of the field tests. The test reports shall include a detailed
tabulation showing values of pressures, flow rates, and all adjustments
recorded during the final tests, and adjustment and calibration of the
entire system. During each test run, the following data and observations
shall be recorded:
a.
Control operation
b.
Voltages
