Centrifugal compressor bearing spare parts incoming inspection procedures

Centrifugal compressor bearings 2020 - spare parts incoming inspection procedures 02 - 1 data review 1 15 radial bearing. 1 clean product information according to the contract is complete. 1. 2 review product quality certificate, certificate of approval and technical documents ( Parts material chemical composition analysis, mechanical property test reports, NDT reports, etc. ) Whether conform to the requirements of relevant norms, standards and drawings. Incoming inspection step 2. Macro check 1 a) Split tile shell split bolt check tile shell points up and down the flatness should conform to the requirements of the drawings, locating pin should be tight. Tighten bolts split split after good mouth, with 0. 02 mm feeler check shall not be into. b） Should check the tile babbit no defects such as crack, metal shed and galling, tile babbit should be achieved. c) Tile back carrying surface should be smooth, uniform along the axial contact with tile shell should maintain contact, swaying around the pivot of tile and cooperate to be not loose pivot pin. Segment in shell to sway, flexible BuKa acerbity. d） Tile with thermal element, its thermal element segment fixation is reliable and loose, lead insulation coating is good. After assembly, heat sensitive components and lead not impede segment in shell flexible oscillation. 2. 2 geometry size and shape tolerance checks a) Outside diameter measurement of bearing box, check its size, roundness and cylindricity should comply with the drawings. b） By using up tile on the false shaft ( Or spare rotor shaft neck) Measuring the bearing clearance shall comply with technical requirements. c) Measuring the thickness of the segment, the same bearing segment thickness difference should be less than 0. 01mm。 3 tile surface penetrant inspection inspection requirements, babbitt should be achieved. Thrust bearing 1 data review 1. 1 clean product information according to the contract is complete. 1. 2 review product quality certificate, certificate of approval and technical documents ( Parts material chemical composition analysis, mechanical property test reports, NDT reports, etc. ) Whether conform to the requirements of relevant norms, standards and drawings. Incoming inspection step 2. Macro check 1 a) Check the thrust tile back carrying surface should be smooth, babbitt should be no crack, metal shed and defects such as hair, tile babbit should be achieved. b） Piece of equalizing carrying surface should be smooth, swaying in the base ring should be flexible, BuKa acerbity. Equalizing swing between flexible. c) Base ring no gourd ladle flexure deformation, two and a half ring joint surface level off good mouth. d） Tile with thermal element, its thermal element segment fixation is reliable and loose, lead insulation coating is good. 2. 2 geometry check a) Thrust bearing outside diameter and thickness should comply with the drawings. b） Measuring the thickness of the segment, the same pair of bearing segment thickness difference should be less than 0. 01mm。 2. 3 inspection check the tile surface penetrant inspection, babbitt should be achieved. （ Source: the chemical equipment and machinery)
