将整筒管式抽油泵柱塞与泵筒间的环形间隙处理为渐缩间隙,并获得了静、动态环隙漏失量的一般表达式。文末算例表明,渐缩间隙模型的环隙漏失量比平行平板模型的环隙漏失量小得多。
The annular gap between the plunger of the whole tube - type oil pump and the pump barrel is treated as a tapered gap, and the general expressions of static and dynamic annular leakage loss are obtained. The results show that the annular gap loss of the tapered gap model is much smaller than that of the parallel slab model.
