5.Removing Damage from Steel Parts
清除钢制零件上的损伤
C.Method No. 405C: Seal Diameter (Lip Seal Surface) Repair Using Glass Bead Peening
Method No. 405C: 使用玻璃珠喷丸修复密封直径（唇形密封面）
NOTE: Do not perform the repair if damage cannot be removed without reducing seal diameter to less than minimum specified in applicable manual for unit in work.
注：工作中，如果损坏不能在不将密封直径减小到小于适用手册中规定的最小值的情况下消除，则不要进行修理。
Repair damaged or worn lip seal surface to restore sealing surface as follows:
修复损坏或磨损的唇形密封件表面，以恢复密封面，如下所示：
(1) Mask off areas not to be repaired.
遮盖不需要修复的区域。
(2) Prepare abrasive material as follows:
按如下方式制备磨料：
(a) Mix glass beads C08-0013 with garnet grit C08-0012 in equal parts by volume.
按体积等量混合玻璃珠C08-0013和garnet grit C08-0012。
(b) Disperse glass bead and garnet grit mixture in ten times the volume of tap water.
将玻璃珠和garnet grit分散在10倍体积的自来水中。
NOTE: Make sure to add 0.25 percent of sodium dichromate C04-0036 to the tap water before mixing with the glass beads and garnet grit mixture.
注：在与玻璃珠和garnet grit混合之前，确保向自来水中添加0.25%的重铬酸钠C04-0036。
WARNING: USE THE CORRECT PERSONAL PROTECTION. COMPRESSED AIR WILL CAUSE LOOSE PARTICLES THAT CAN GET IN YOUR EYES. COMPRESSED AIRFLOW CAN CAUSE CUTS. DO NOT POINT IT AT YOUR SKIN.
警告：请使用正确的个人防护装置。压缩空气会产生松散的颗粒，可能进入眼睛。压缩气流会造成割伤。请勿将它对准皮肤。
(3) Peen sealing surfaces specified in applicable manual. Use peening chamber (PerfectoPeen Cabinet).
根据适用手册中规定的喷丸密封表面。使用喷丸室(Perfecto喷丸柜）。
NOTE: The peening process produces a more compatible surface for mating with lip seal and will prolong life and improve function of seal.
注：喷丸处理可产生更兼容的表面，以便与唇形密封配合，并将延长密封寿命并改善密封功能。
(4) Refer to applicable manual to setup, pressure, nozzle distance, rotating speed and impingement time.
有关设置、压力、喷嘴距离、旋转速度和冲击时间，请参阅适用手册。
(5) Visually check the repaired surface. Surface texture must be uniform, free of wear rings, nicks, dings and gouges. Use a power optical glass 3X to 7X magnification.
目测检查修复表面，表面纹理必须均匀，无磨损环、缺口、凹痕和沟槽。使用3X至7X放大倍率的放大镜。
(6) Demask and rinse the part in clean water to remove peening material.
取下防尘罩，用清洁水冲洗零件，以去除凹痕材料。
(7) Let the part dry to room air.
使零件在室温下干燥。
(8) Dimensionally check peened surfaces. Repaired surfaces shall meet dimensional requirement specified in applicable manual.
对喷丸表面进行尺寸检查。修复后的表面应符合适用手册中规定的尺寸要求。
(9) Apply a uniform layer of lubricating oil C02-0009.
均匀涂抹一层润滑油C02-0009。
