The design and construction of pumps shall be in accordance with the space and weight requirements as spe
29、cified (see 6.2 and 6.3). The pump unit shall perform under the list, pitch, roll, and trim conditions in accordance with MIL-STD-1399, section 301. Pumps shall operate continuously at any point over the entire flow range and design conditions as specified (see 6.2). 3.2.1 Reliability. The requireme
30、nts of this specification are imposed exclusively to obtain equipment of utmost reliability for the service intended. The assurance of maximum reliability shall be the paramount controlling principle in the design, fabrication, assembly, and testing of this equipment. Users of and contractors to thi
31、s specification are urged to communicate to NAVSEA any findings related to the requirements or lack of requirements of this specification whereby improvement of equipment reliability can be achieved. 3.2.2 Maintainability. The equipment specified herein shall be operated, maintained, and repaired on
32、 board Navy ships. Attention is directed to the high equipment density of shipboard machinery spaces, to the fact that maintenance and repair will be made underway in heavy seas, that equipment will operate unattended, and that maintenance personnel may not be seasoned mechanics. The requirements fo
33、r maximum reliability directly relates to those shipboard environmental and service conditions, and those requirements shall be fully considered in the pump design. The aspects of “human engineering“ shall also be fully explored and considered in the equipment design to minimize the possibility of f
34、ailure through improper operation and maintenance and to preclude personnel safety hazards. 3.2.2.1 Maintenance. The equipment shall have maximum repair accessibility for ease of examination of wearing parts and for simplicity of disassembly and proper reassembly. Positioning and alignment of parts
35、in assembly shall employ positive means such as shoulder, tongue, and groove, or other locating techniques whereby correct reassembly is repeatedly assured. In consonance with the concept of ease of maintenance and where not otherwise specified, the pump 6 Licensed by Information Handling ServicesMI
36、L-P-22302A(SH) designer shall consider all of the following features for incorporation in the design and technical documentation wherever such incorporation will significantly contribute to ease of maintenance without compromising performance reliability: a. b, d. e. f. g. h.

Thoroughness of operating instructions n. Thoroughness of preventive maintenance instructions o. Explicit assembly and disas
39、sembly instructions p. Exploded views of critical assemblies q. Adequate system diagrams. 3.2.2.2, Service life. Each pump shall have a service life of 30 years of which 40 percent shall be actual operation. There shall be no limit on the number of starts during the life of the pump. It shall be ass
40、umed that during the life of the pump, parts subject to unavoidable wear and deterioration (with the exception of packing and seals) will be replaced at intervals no shorter than 3 years. The parts subject to wear, deterioration, and normally requiring replacement at 3-year intervals during the serv
41、ice life of the pump (with the exception of packing and seals) shal have a life of 10, actual operating hours, and they shall be identified in appropriate drawings and manuals. 3.23 Shock and vibration. 3.23.1 Shock. Pumps and drivers, all appurtenances, and controls shall pass a shock test in accor
42、dance with MIL-S-901, grade A, in accordance with 4.6.7.2. 3.23.2 Mounts. Shock mounts (resilient mounts for shock attenuation) shall not be used. When noise attenuation mounts are specified (see 6.2), the pump shall pass the specified shock test without attenuation mounts. 3.233 Bolts. Bolts design
43、ed to be stressed in shear shall be installed in holes with a minimum of clearance. Hole diameters shall be not more than 1/32 inch larger than the bolts for sizes up to and including 3/4-inch, and no more than 1/16 inch larger than bolts of greater than 3/4-inch size. 7 Licensed by Information Hand

Pumps shall not be damaged or caused to malfunction by either environmental vibrations or by internally excited vibrations. When specified (see 6.2), units furnished under this specification shall be tested in accor
45、dance with MILSTD-167-1, types I and II. 3.2.4 Alignment, 3.2.4.1 Stress. The design of all pumps shall be such that alignment will not be disturbed or undue stresses set up in any part by normal vibration or contraction and expansion of piping attached thereto in service. 3.2.4.2 Attachment. Alignm
46、ent between separate components of a unit shall be maintained by means of keyways, rabbeted or tongue and groove joints, fitted bolts, or other means. 3.2.43 Support. In no case shall a piece of equipment be rigidly supported from more than one plane. 3.2.5 Noise. The design, construction, and workm
47、anship of the equipment shall be such that noise levels during operation at the design conditions will meet the airborne noise and structureborne vibration noise requirements as specified (see 6.2 and 4.6.4). 3.2.6 Mounting. 3.2.6.1 Pump. Pump units shall be horizontally mounted. 3.2.6.2 Bedplate. E
48、ach pump unit, complete with all appurtenances, shall be mounted on a common bedplate. 3.2.63 Alignment. Bedplates shall be sufficiently rigid to permit handling, shipment, and installation of the units on board ship, to minimize misalignment of the assembled units; and so that normal distortion, we
49、aving or vibration of the supporting structures on board ships cannot cause misalignment between the pumps and driving units. 3.2.6.4 Surfaces, Bearing and seating surfaces of bedplates shall be finish machined (see 3.2.7.3.1). 3.2.6.5 Oil reservoir.
