detail drawings are required (see .3.6.l.2.3) as well as quantity required,
material type, and materials specification for all parts.Parts shall- be named
to indicate the function they serve.Parts for which detail drawings are not
required shall be identified as the dimensions. The list of materials may be
shown on the sectional assembly drawing.
3.6.1.2.3 Detail drawing. Detail drawings shall be furnished of all
parts and sub-assemblies necessary for evaluation of the equipment and of all
parts necessary for maintenance and overhaul of the pumps. Detal of these
.
parts shall be-so complete as to permit emergency manufacture by a Naval ship-
yard without assistance from the original manufacturer. Details of pump casing
shall be furnished, but the dimensioned development of cored hydraulic passages
need not be shown. Sub-assemblies whose parts cannot be acquired or serviced
individually shall be shown as a single part and so indicated. Multi-detail
drawings are preferred, but monodetail drawings may be used.
3.6.1.2.3.1 Impeller machining and inspection drawing. Detail drawings
shall explicitly require that each impeller, including spare and replacement
impellers, be dynamically balanced to less than the maximum ounce-inch residual
imbalance allowed by MIL-STD-167-1 (type II) for the impeller's weight and
rotational speed.
3.6.1.2.4 Outline drawings and certification data.
3.6.1.2.4.1 Outline drawings and certification data shall be in the form
of supplemental drawings to all sectional assembly and detail drawings.
Separate outline drawings, drawing lists, and certification data shall be
furnished under each contract or order unless the complete equipments covered
by the outline drawing and the referenced drawings are in fact identical in
all respects.
3.6.1.2.4.2 The outline drawings, in addition to the certification data
required, shall contain the following:
(a)
Dimensional outline assembly drawing of the pump with its prime
mover, bedplate, and attached auxiliaries.
Complete performance data of pump, prime mover, and attached
(b)
auxiliaries , if applicable.
Complete equipment performance curves, based on actual tests
(c)
(the original submission may show design performance curves
vice test curves).
Weights of major sub-assemblies over 50 pounds, such as, rotor,
(d)
upper half-casing, and impeller; and the weight of the complete
unit including driver, dry and in operating condition.
(e)
Shipbuilder's connections showing size, type, and dimensions of
flanges.
(f)
Center of gravity of the pump component and of the complete
assembly.
Radii of gyration of complete assembly about each of the three
(g)
principal axes.
(h)
Identification of system in which installed.
(i)
Critical speed.
Maximum thrust loads.
(j)
