电动机的负荷率大部分在10%-20%，的也不过30%，首先，抽油机启动时都是带载启动，惯性矩较大，启动时又总在上下死点处启动，油田在选配电机时为了启动顺利，不影响生产，一般按扭矩选配电机，而抽油机启动后正常工作时平均转矩与扭矩相比又较低。 我们认为，用第三种方法既简单又可行，因为采用计算机计量所供用户的用气量一般都比较恒定，用这种方法补偿，误差较小,另外，除特殊情况外，起停计量的时间应尽量安排在供气较平稳的时间，但是,补偿计量要杜绝暗箱操作。Sinwoo S-CON变送器ACC-7A1-W ACC-7A1-X ACC-7A1-Y ACC-7A1-Z ACC-7A2-W ACC-7A2-X ACC-7A2-Y ACC-7A2-Z批发价格
