Test procedures.
4.5.4.1
Operational test.
The pump, containing twenty cubic centi-
meters of oil, see 6.7, shall be mounted in the test stand and connected
the auxiliary equipment. Prior to testing, the flow rate shall be preset
to
as folows: remove the Adjusting Screw Nut (Figure 1), apply a pressure Of
300 10 psig to the bias port. With the pump being driven at 3880 10
rpm, set the inlet pressure to 7 3 psig. Position the Valve Adjusting
Screw (Figure I) to obtain an outlet pressure of 2775 10 psig. Replace
the Adjusting Screw Nut and secure with a lockwire. The pump shall be
operated in accordance with the sequence indicated in Table XI. The pump
shall deliver the working fluid at the pressures specified in Table XI,
when the pump is driven at 3880 10 rpm, bias pressure is controlled within
the respective parameters and the inlet pressure in maintained between 4
and 10 psig. The orifice shall not be by-passed thus unloading the pump
during the test.
