针对常规电动潜油离心泵因受泵径限制难以增大排量和扬程的问题，研制了一种以增速器配套的增速潜油电泵。增速器采用二级齿轮结构型式，传动比为145，输出转速为4130r/min，安装在上、下保护器之间。为满足高转速要求，从结构和材料上改进了离心泵止推垫片，以及上保护器的扶正轴承和止推轴承。两套增速器样机，以及与之配套的增速泵，分别通过了室内性能试验和试验井模拟试验，其中一台并已投入现场试验。这些试验的性能参数都达到了设计要求。增速电泵扩大了现有电泵的适应范围。在相同条件下，增速电泵导叶轮总量比常规电泵减少60%，仅此一项即可降低一半以上的综合制造成本。整机总长度明显缩短，更适于斜井使用。
Aiming at the problem that conventional electric submersible centrifugal pump is difficult to increase displacement and lift due to the limitation of pump diameter, a submersible submersible pump with speed increasing device is developed. Speed gear with two gear structure type, transmission ratio of 145, the output speed of 4130r / min, installed in the upper and lower protector. To meet the high speed requirements, from the structure and materials to improve the centrifugal pump thrust washers, as well as the right protection bearings and thrust bearing fairing. Two sets of gearbox prototype, and its accompanying growth pump, respectively, passed the indoor performance test and test well simulation test, one of which has been put into field test. The performance parameters of these tests have reached the design requirements. Speed pump to expand the scope of the existing pump adaptation. Under the same conditions, the total speed of the impeller of the speed-increasing electric pump is reduced by 60% than that of the conventional electric pump, and this alone can reduce the comprehensive manufacturing cost by more than half. The total length of the machine significantly shortened, more suitable for inclined shaft use.
