| 摘 要： | 提高压裂泵柱塞寿命是压裂过程中的重要问题。为了解决这一问题，用流体动压润滑理论的观点，研究了ＯＰＩ－１８００ＡＷＳ型三缸压裂泵柱塞密封副在强制性全损式润滑下的润滑机理（即摩擦界面油膜形成的原因），并建立了摩擦界面间最小油膜厚度的计算公式。研究表明，在压裂泵的排出和吸入行程，均能满足流体动压润滑的条件，亦即在柱塞与密封界面上能形成并保持一厚度为的平行油膜润滑密封，从而达到减小摩擦提高寿命的目的。说明在压裂泵的操作使用中，强制润滑是至关重要的。

| Abstract: | Based on the theory of fluid hydraulic lubrication, the plunger-seal pair of fracturing pump in OPI-1800AWS is discussed in detail. The mechanism of film formation under forced lubrication conditions is studied, and the minimum film thickness between the plunger and the seal is decided. During the out-let and in-let stroke, the conditions of fluid hydraulic lubrication is met, i.e., there is a parallel film between the plunger and the seal, so the friction is decreased and the lifetime of the plunger-seal pair extended. This suggests that forced lubrication plays a key role in the operation of fracturing pumps. |
