抽油机电动机合理负载率的研究
Reasonable Range of Electrical Motor Power Utilization Ratio of Pumping Units
摘要
Abstract
The load characteristic of pumping units is a cyclicity loading. In order to startup and run the pumping units normally, the electrical motor theory installed power of pumping unit was usually higher than running power for requirement of the motor margin, which makes the electric power lost. The reasonable upper limit of electrical motor power utilization ratio by theorical check of the motor heating conditions, overload capacity and startup character and the lower limit by characteristic curve of electrical motor were made. It had been checked by experimental study. Declining electrical motor of pumping units installed power reasonably not only can raise electrical motor power utilization ratio and decrease inirial investment, but also can make importance for energy saving of oilfield.关键词
