本文用了大量试验数据说明,我国与国外先进水平相比,抽油机-深井泵装置系统效率太低.国外常规抽油机系统效率为47%,改进后效率为59%,而我国常规抽油机系统效率为20.5%.提高抽油机-深井泵装置系统效率的关键就是要提高系统的分效率.其具体做法是:①在电动机上采用多功能节电箱和功率因数控制器,可分别节能2～9%和10～45%;②采用窄V带传动效率可提高4%,采用同步带可节能15%;③将常规型抽油机改为偏置机,即将对称循环的四连杆机构改为非对称循环,可节能13～25%;④采用玻璃钢抽油杆或连续抽油杆,以及在钢质抽油杆上装设滚轮;⑤设计新型高效深井泵;⑥加强管理.
In this paper, a large number of test data show that compared with the advanced level in foreign countries, pumping unit - deep well pump system is too low efficiency system abroad conventional pumping unit efficiency of 47%, after the improvement of efficiency of 59%, while China’s conventional pumping The efficiency of the oil system is 20.5%. The key to improve the system efficiency of the pumping unit-deep well pumping unit is to improve the efficiency of the system. The specific approach is: (1) multi-function energy-saving box and power factor controller Respectively, saving 2 to 9% and 10 to 45%; (2) the use of narrow V-belt drive efficiency can be increased by 4%, the use of timing belt can save 15%; ③ conventional pumping unit to a biasing machine, about four Linkage mechanism to asymmetric cycle, energy saving 13 ~ 25%; ④ FRP sucker rod or continuous sucker rod, as well as the installation of steel sucker rod; ⑤ design new and efficient deep well pump; ⑥ strengthen management.
