全国各地为了大力发展经济建设,营造好的投资环境、规范管理及优质服务等有效方式招商引资。规划建立了许多集中化、特色鲜明的工业园区或技术开发区。在这类开发区内入驻企业绝大部分产品技术含量高、生产集约化。其生产车间大多为2、3层的标准厂房。车间内垂直运送货物的多为提升高度不大(5m~7m)、载重量较大(2t及以上)的交流双速载货电梯(以下简称低层站货梯)。本文就此类电梯实施监督检验时,所采用测量验证平衡系数的电流法及测量过程可能的误差加以分析。
Throughout the country in order to vigorously develop the economy, create a good investment environment, standardize management and quality service and other effective ways to attract investment. Planning to establish a number of centralized and distinctive characteristics of industrial parks or technology development zones. In the development zone, most of the settled enterprises have high technical content and intensive production. Most of its production workshop for the 2,3-storey standard plant. The vertical delivery of goods in the workshop is mostly AC double speed freight elevators (hereinafter referred to as low rise freight elevators) with a small lift height (5m ~ 7m) and large load capacity (2t and above). In this paper, the implementation of supervision and inspection of such elevators, the use of measurement and verification of the balance coefficient of the current method and the possible error of the measurement process be analyzed.
