ALL DIMENSIONS IN PARENTHESIS ARE REFERENCE DIMENSIONS. DIMENSIONS ENCLOSED ARE INSPECTION DIMENSIONS;腔体均由实体模型转换得来。此图纸仅限于二次机加工和模型尺寸校核之用。括号尺寸为参考尺寸;圈出来的尺寸为检测尺寸;未注尺寸参见三维模型； UNLESS OTHERWISE SPECIFIED, TOLERANCE PER NADCA, TITLE BLOCK FOR REFERENCE未注公差请见NADCA标准，标题栏内为辅助参考 DETAIL CORNERS AND CHAMFERS REFER TO SOLIDWORKS MODEL; OTHERS REFER TO TITLE BLOCK;导圆倒角具体参见SOLIDWORKS模型;其余参见标题栏，一般为0.3mm; SURFACE FINISH MUST BE 3.2 FOR ALL MARKED JOINT SURFACE; SCREWED SURFACE MUST BE 3.2; OTHERS REFER TO TITLE BLOCK;所有标注的隔爆面的表面粗燥度一律为3.2;螺纹面光洁度必须为3.2;未注表面粗燥度参见标题栏; COMMON REQUIREMENTS ACCORDING TO NADCA;一般压铸要求根据NADCA标准 3 mm MINIMUM WALL THICKNESS REQUIRED UNDER AND AROUND ALL HOLES IN PRESSURIZED WALLS;NO ADDITIONAL HOLES OR MACHINING ALLOWED;所有承压壁上的孔的周围金属厚度最小3 mm;不允许有设计之外

的孔和机加工； REMOVE ALL BURRS AND ALL SHARP EDGES去除所有毛刺和锐边 EXCEPT AS NOTED ON DRAWING,MAIN BODY FINISH IS CLEAR IRIDITE; EXTERIOR SURFACES EXCEPT FOR JOINT SURFACE AND MATING SURFACE COATED WITH POWDER;COLOR: RAL 7043; DETAIL REQUEST REFER TO PAINTING DOCUMENT ATTACHED;主腔体表面处理除了图中特别标明外，均需做表面硬化，防锈防腐处理；外表面除了隔爆接合面和配合面以外须做喷粉处理，其中主腔体外表面喷粉色号：RAL 7043;喷粉要求参见附带喷涂文档； AFTER MACHINING, PART MUST WITHSTAND MIN. 1.5MPa HYDROSTATIC TEST, HOLD FOR 60 SECONDS . NO DAMAGE AND PERMANENT DERFORMATION LEADING TO FLAMEPROOF FAILURE;机加工后零件必须进行最小1.5MPa水压实验。历时60秒，以无损坏和影响隔爆的永久变形为合格; * MARKED AREAES ARE FLAMEPROOF JOINTS. CASTING BUBBLES BIGGER THAN 0.4MM ARE ALLOWED ONLY WHEN (1) LENGTH/DIAMETER OF SUCH BUBBLES MUST SMALLER THAN 0.8mm; (2) TOTAL LENGTH OF BUBBLES IN ANY DIRECTION MUST BE LESS THAN 2mm; (3) MAX. AMOUNTS OF BUBBLES IN EACH FLAMEPROOF JOINT MUST BE LESS THAN 5; (4) TRY TO CONTROL BUBBLES BE IN END OF THREADS; *号标记的地方为隔爆面，允许出现0.4mm以上尺寸的砂孔；前提是(1)必须控制单个砂孔长度/宽度/直径小于0.8mm;(2)任意直线方向上所有砂孔加起来的总长度不超过2mm;(3)任意一个图示隔爆面上砂孔数量小于5个；(4)砂孔分布位置最好能控制在螺纹的根部； FOR NONE-JOINT SURFACE, CASTING BUBBLES SHALL BE NOT OVER 2.4mm WIDE AND NOT OVER 1.6mm DEEP; THESE HOLES SHALL NOT AFFECT THE MIN. THICKNESS;非隔爆面上，砂孔的长度/宽度/直径不能超过2.4mm,深度不超过1.6mm;砂孔不可影响最小壁厚； CASTING BUBBLES MUST BE INSPECTED 100%FOR EVERY PIECE OF PARTS;必须100%检测每一成品件的砂孔;
