Anotácia textu normy ASTM F998-12(2022) :
This specification covers the requirements applicable to the design and construction of three classes of centrifugal pump (Class 1, Class 2, and Class 3) for shipboard application. When selecting material combinations, the conditions under which the various materials interact with each other shall be taken into consideration as well as the use of nonmetallic (composite) pump components where the use of that material can benefit the operation and maintenance of the pump. The requirements for the following are detailed: (1) pump design and construction, (2) pump operation (at or near the best efficiency point), (3) motor power ratings, (4) pitch and roll conditions, (5) horizontal pump and driver mounting, (6) vertical pump support, (7) bedplates, (8) pump couplings, (9) guards, (10) pumps with face-mounted motors, (11) shaft alignment, and (12) indication of direction of rotation. Pump design requirements for inlet and outlet connections, casings, radial and thrust bearings, journal and thrust bearings, rolling element bearings, mechanical seals, separate pressure boundary parts, and screw threads are specified. Requirements for paintings and coatings, equipment identification plates, and testing such as hydrostatic, mechanical run, performance, net positive suction head, vibration, and acoustic tests are also specified.

1.1?This specification covers the requirements applicable to the design and construction of centrifugal pumps for shipboard application. The three classes of service covered by this specification are as follows: 1.1.1?Class 1Freshwater, 1.1.2?Class 2Seawater, and 1.1.3?Class 3Hydrocarbon pumps (less than 1500 SSU). 1.2?The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3?This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. |
