在现行机务统计报表中要求,各建筑安装施工企业在统计主要机械设备“两率”情况有关数据的同时,还要统计“年内故障次数”与“年内故障影响作业台时”两项指标数值。可是,大多数施工企业上报的统计资料中,上述两栏往往都是空白。不少施工企业对机械设备产生故障以及因故障停机而造成的损失,尚未引起应有的重视。机械设备产生故障,既有设计和制造的原因,也有运行时操作的失误。其性质分为精度和机能两类。精度的故障主要是设备的几何、传动、动态三方面精度及其产品加工的工序质量;
It is required in the current maintenance statistics that each building installation and construction company is to count the “two-rate” situation of the main machinery and equipment, as well as the statistics of the number of “failures during the year” and “when the failure during the year affects the workbench”. However, in most statistical data submitted by construction companies, the above two columns are often blank. Many construction companies have not paid due attention to the mechanical equipment failures and losses caused by downtime. Failure of machinery and equipment, both for design and manufacturing reasons, as well as errors during operation. Its nature is divided into two types of precision and performance. The accuracy of the fault is mainly the three dimensions of the equipment geometry, transmission, dynamic accuracy and process quality of the product processing;
