Research And Development Of Special Frequency Converter For Pumping Unit

Crude oil extraction process, Regular pumping motor in a "big car Mara" state of the work. Also, the pumping speed-regulating wasting time and effort. Although in recent years the energy-saving equipment for oil wells, speed machinery, activate protection devices, complex and varied, but only solve certain problems, we can not fully satisfy the requirements of the production site. VVVF technology is the best mechanical transmission drive control and energy saving technology. We therefore under the condition pumping characteristics of a well developed specifically dedicated frequency converter.Its main role is to beam pumping unit urgently needs the five aspects of organic integration of the important functions of collection as one, reattachment of a conventional motor protection features not only perfect functions, and can effectively reduce costs.Currently, the device has been successfully estuary Oil Production Plant in blocks of 72 sets of heavy oil, oil production plants in the estuary of low permeability Oilfield five sets, integrated energy-saving rate of 15 ~ 45%, an increase of system efficiency over 15%, the rest of the technical indicators are designed to achieve the desired objectives devices.
