目前使用的常规游梁式抽油机存在噪声大、耗能大及参数调节不便等问题,因此,引入了天平式游梁抽油机,该机型采用柔性传动系统,取消了四连杆机及齿轮减速箱,不仅提高了传动效率,而且提高了零部件的耐用性。天平式游梁抽油机采用变频永磁同步电机系统,节电效果明显。现场试验表明,试验井使用常规游梁式抽油机,日耗电量为257kW·h。改型后,日耗电量为154kW·h,节能效果十分明显。
The conventional beam pumping unit currently used has the problems of large noise, large energy consumption, inconvenient adjustment of parameters, etc. Therefore, a balance beam pumping unit is introduced. The flexible transmission system of the beam pumping machine is adopted, and the four- And gear box, not only improve the transmission efficiency, but also improve the durability of parts. Balance beam pumping unit adopts variable frequency permanent magnet synchronous motor system, energy-saving effect is obvious. Field tests show that the test wells use a conventional beam pumping unit, the daily power consumption of 257kW · h. After retrofitting, the daily power consumption of 154kW · h, energy-saving effect is very obvious.
