在彩涂板设备维修工作中,为了恢复设备的性能和精度,保证加工产品的质量,用新制的或修复的零件来更换已磨损或老化了的机器旧件,通常把这些新制的或修复的替换零件称为配件。为了缩短设备修理的停歌时间,使故障损失减少到最低限度,就需要在备件库内预先储备一定数量的配件,通常把这种配件称为备件。
彩涂板设备的备件管理是指备件的计划、生产、订货、供应、储备的组织与调配。彩涂板要搞好这项工作,设备管理员首先要清楚彩涂线的工艺和生产流程,才能确定机组中哪些是备件,线上各种备件应如何分类和如何储存。
(7)起保持设备精度作用的主要运动零件,如主轴、轴瓦、丝杆、七级精度以上的齿轮、蜗轮副,空压机的曲轴、活塞、锤杆、钻杆等,列为备件。
In the process of equipment maintenance, in order to restore the performance and accuracy of the equipment and ensure the quality of the processed products, the worn or aged old parts of the machine are replaced with new or repaired parts, which are usually
called accessories. In order to shorten the downtime of equipment repair and minimize the failure loss, it is necessary to reserve a certain number of spare parts in advance in the spare parts warehouse, which is usually called spare parts.
Spare parts management of color coating equipment refers to the organization and deployment of spare parts planning, production, ordering, supply and reserve. In order to do this work well, the equipment manager must first be clear about the
process and production process of the color coating line, so as to determine which spare parts are in the unit, how to classify and store various spare parts on the line.
A. determination of spare parts
Spare parts should be separated from equipment, low value consumables, materials, tools, etc. However, it is difficult to accurately divide a few items, and the scope of each enterprise is not the same. It can only be determined according to
the actual situation of the enterprise on the premise of convenient management and collection. Therefore, the determination of spare parts to distinguish the situation, specific analysis. The spare parts of color coating unit can be determined according
to the following principles:
(1) All purchased parts, such as rolling bearings, electrical appliances, belts, chains, oil seals, etc., can be listed as spare parts. Standard fasteners, such as bolts and nuts, belonging to low value consumables, shall not be listed.
(2) Vulnerable parts with large consumption are listed as spare parts. However, some vulnerable parts, which are easy to process, can not be listed as spare parts. (3) The parts which are easy to be damaged, have long manufacturing cycle, many
processes, complex processing and need casting and forging blanks are listed as spare parts.
(4) Frequently impacted and easily damaged parts, such as sewing machine mold, etc.
(5) For the equipment with the same model and a large number of sets, its parts should be listed as spare parts, and a certain variety of spare parts can be selected according to the requirements of its use. Such as polyurethane coating roller,
rubber steering roller, squeezing roller, etc.
(6) Some parts of the gearbox, such as gears, shafts and forks, should be listed as spare parts according to the transmission situation.
(7) The main moving parts, such as main shaft, bearing bush, screw rod, gear and worm gear pair with grade 7 accuracy or above, crankshaft, piston, hammer rod and drill pipe of air compressor, are listed as spare parts.
