备件是设备维修的重要物质基础之一。及时供应备件,有利于设备的计划修理。但备件储备过多会占用较多的资金和库容量;而储备不足会延长设备的修理停台时间。在设备处于更新换代、挖潜改造的当今,要注意选购同型号的设备,切忌选购加工范围和性能相近而型号各异的设备(包括型号相同而制造厂家不同的设备),以免带来备件管理效能的降低。 一、备件的最佳储备量 备件管理的着重点在于合理控制最佳储备量。 1.自制备件类 最低储备D_(min)= n· P+ 2K(1) 最高储备 D_(max)=1.5D_(min)(K~2+1)(2)
Spare parts are an important material basis for equipment maintenance. The timely supply of spare parts is conducive to the planned repair of the equipment. However, too much reserve of spare parts will occupy more funds and storage capacity; and insufficient reserve will prolong the time for equipment repairs. In today’s modernization and upgrading of equipment, attention should be paid to the purchase of equipment of the same type. Do not purchase equipment of different types and sizes that have similar processing ranges and performance (including equipment of the same model but different from the manufacturer) so as not to bring in spare parts. Reduced management effectiveness. First, the best spare parts spare parts Spare parts management focuses on the reasonable control of the best reserves. 1.
