MIL-P-24475(SHIPS)
Where:
Ns = specific speed at the best efficiency point.
Effects of thrust reversal where conditions which might cause
(2)
thrust reversal exist.
(3) Effects of roll, Ditch, list and trim of the ship (including
gyroscopic effects shall be considered in the bearing design.
Analysis of driver bearings for close-coupled or rigidly coupled units.
(c)
(d)
Calculations of the worst-case cumulative effect of dimensions and tolerances
for parts and locations. These calculations shall demonstrate:
(1) There will be no interference between rotating and stationary parts
as assembled.
(2) There will be no Interference between rotating and stationary parts
and hence no reduction in life of'wearing parts, when these worst
case cumulative effects arc combined with operational environmental,
and thermal loading.
3.7.4 Drawings shall be submitted to allow an independent review of the design. A
sectional assembly and outline drawing with detail to fully present the unit is a minimum
requirement . All dimensions and tolerances necessary to determine clearances between
rotating and stationary parts, interferences fits and tolerance stack-ups shall be provided.
3.8 Design record. A design record when required shall be submitted to the command
--
--.
or agency concerned. This record shall be completed except as noted in 3.$1.2, and forwarded
prior to unit delivery or at a tiem agreed to by the command or agency concerned?.
3.8.1
The design record shall conform to the following:
The design calculations which were submitted for manufacturing release.
(a)
except as modified to resolve comments at time of manufacturing release.
(b) Revised calculations in those areas of design where the original calculations
must be modified as a result of an accepted design change.
(c) Accepted design evaluation test reports, including resolution of comments
in the approval action and any special testing which may be performed to
verify new design features.
3.8.2 Changes in pump design accepted subsequent to issue of the design record when
required, or approved deviations in the design evaluation test unit from the design described
in the design record shall be submitted as an addendum to the design record. The addendum
shall include applicable revised drawings
3.9 Onboard repair parts and tools.
3.9.1 Onboard repair parts. A set of repair parts (onboard) shall be furnished in
accordance with
method B paragraph 3.3.2) of MIL-P-15137 (see 6.2) and for guidance purposes
shall consist of the parts specified in table I and special tools and wrenches required for
servicing of the pumps.
3.9.1.1 The pump rotor assembly for flexible-coupled axially split case units shall
be completely assembled ready for Installation in the unit for which intended and shall
include any nonrotating parts which can be installed only by removing some rotating part
or parts of the pump rotor.
