REQUIREMENTS 3.1 Qualification. - The compressors furnisned under this specification shall be a product which has been tested and hacpassed the qualification tests specified herein (see 6.2). 3.2 Description. - 3.2.1 Class T compressors shall be reciprocating,

28、vertical, single acting, multi-stage machines having capacities of 10 c.f. m. or 50 c. f. m. of free air per minute actually delivered at 600 pounds per square inch gage (p. s. i. g. ) discharge pressure. Each compressor chau be capable of continuous operation at any discharge pressure from 150 to 6

29、00 p. S. i. g. common bedplate, and shall include all necessary appurtenances and electrical control equipment. parts, shall be incorporated in the compressor design. 3.2.2 A complete compressor unit shall consist of the compressor and motor mounted on a 3.2.3 Safety features including guards for be

30、lts, flywheels, sheaves, and other exposed moving 3.2.4 The arive shall be of the rr,uiti-64V”-belt type. Suitable means shall be provided for tightening and adjusting the belts. 3.3 General design. - 3.3.1 The principle of reliability is paramount and no compromise of this principle shall be made w

31、tth any other basic requirements of design. It is the intention of this specification to obtain alr com- pressors of such design that they will operate over a long period of years with a minimum of servicing. Where wear or corrosion is unavoidable the parts subjected to such wear or corrosion shall

32、be of the best materials available for the purpose in order to reduce these detrimental effects to a minimum. The design and construction of all alr compressors shall be the most compact consistent with the following requirements: (a) Reliability. (b) Accessibility for repair, (c) Resistance to wear

33、 or corrosion. (d) Economy. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL- C- 16645A(SHIPS) (e) Satisfactory optr i A . :- 2 as follows: (1) up to 1E 3- ;-”* . . 1. -_ :ion (permanently inclined).

35、. ). (b) Intake air pressure - 14. p. s. i. absolute. (c) Relative humidity - 50 perceqt. (d) Maximum permissible temperature of air leaving the aftercooler - 100F. (e) Temperature of cooling water at inlet - 85F. (f) Kind of cooling water - sea (salt). 3.3.3 Piston speed. - The piston speed shall n

36、ot exceed 800 feet per minute. 3.3.4 Gage board, drain valves and all features of an operational nature shall be loca_?d on or operable from one side, designated as the operating side of the compressor, SO as to be accessible if the compressor is installed adjacent to a bulkhead. 3.3.5 The crank cas

37、e, frame, housing, cylinders, and other fixed parts or attached components of the assembly shall be rijidly secured and held in alignment by dowel pins, fitted bolts, keys, rabbeted or tongue and groove joints or other suitable means. 3.3.6 Air cylinders and heads. - The cylinders and heads shall be

38、 provided with ample water- jackets (see 3.3.15.1.1). So far as practicable hand-holes shall be provided for access to the jacket spaces. Cylinder liners shall be held rigidly in place. The liners Shall be counterbored slightly at the ends to permit the piston rings to override the working bore to a

39、void the formation of shoulders. The design and macyning of cylinders and liners shall be such that the complete piston assembly can be removed and replaced. To this end all shoulders where piston rings may catch shall be avoided and liners shall be properly beveled. 3.3.7 Connecting rods. - The low

40、er end of connecting rods shall be arrangedfor renewalof crankpin bearings which shall be of thin shell precision type. Bolts and nuts for securing crankpin bearings shall be positively locked. The upper end of connecting rods connected to crossheads or pistons shall be fitted with renewable bearing

41、s. Provision for adjustment shall be made as required for proper operation and maintenance of the compressor. Any take-up bolts and nuts shall be positively locked. Upper end of connecting rods shall be of one-piece construction. 3.3.8 Crankshaft; - The crankshaft shall be a single forging. The cran

42、ks shall be arranged to give the best possible running balance. Counterweights shall be fitted if necessary. The design of the shaft shall be such as to permit convenient use of a portable tachometer. 3.3.9 Flywheels. - Each compressor shaq be equipped with a flywheel of sufficient size to provide s

43、mooth running of the compressor and motor. Flywheels shall be keyed to the crankshaft and shall be pressed or securely clamped thereon. A separate flywheel will not be required if ample flywheel effect is provided by the sheave. 3.3.10 Main and thrust bearings. - Main bearings shall be readily renew

44、able. The main bearing shall preferably be of the tapered roller bearing type in accordance with Specification FF-B-185 which shall be So arranged as to take up the thrust due to roll and pitch of the vessel. Consideration will be given to the use of deep groove or angular contact type ball bearings

MIL- C- 16645A(SHIPS) 3.3. 11 Lubrication. - An adequate and self-contained lubricating system of the force feed type

46、 shall be provided for the main bearings, crankpin bearings, wrist-pin bearings, gears, pinion, and similar items. Consideration will be given to splash feed systems or a combination of splash and force feed systems. The crankpit shall be suitably housed to form a reservoir for the lubricating oil.

47、Splash guards shall be fitted to prevent oil from the crankcase entering the air cylinders. The crankpit reservoir shall be provided with suitable fittings for filling and draining of the lubricating oil. A suitable oil-level gage, marked to show the high, low, and normal oil levels, shall be fitted

48、. Gage glasses, if used, shall be renewable without draining the oil from the reservior. Oil shall be drawn from the reservoir by one or more pumps, positively driven from the compressor crankshaft. The arrangement of the reservior and pump connection shall be such that oil will not be lost from the

49、 reservoir, nor the oil pump lose suction due to roll or pitch of the vessel. The oil shall be properly strained and cooled before being delivered to the parts to be lubricated. Strainer (if provided) shall be fitted on the discharge side of the lubricating oil pump. Satisfactory means of cooling the oil shall be provided. Oil coolers, if provided, shall conform to type A of Specification MIL-C-15730. Coolers shall be class 2 unless otherwise specified (see 6. i). The c
