通过对柱塞泵运行规律的研究发现 ,影响柱塞泵各部配件使用寿命的主要原因是高冲次 ,而影响泵效的直接原因是泵阀的滞后 ,间接原因仍是高冲次的影响。面对北东块聚合物推广区因地下需要而要求泵的大排量与目前泵排量之间的矛盾 ,不能只追求高冲次而不顾泵的正常运转规律 ,因为高冲次而令设备出现故障所带来的直接、间接影响是调大参数后多注的那部分聚合物所不能弥补的。在调参时应保证泵阀与阀座的撞击速度不超过 6 0～ 70mm/s,根据这一原则可计算出各种泵型调参合理的泵排量和电机皮带轮参数
Through the study of the operating rules of the plunger pump, it is found that the main reason that affects the service life of the various parts of the plunger pump is the high impact. The direct cause of the pump effect is the lagging of the pump valve. The indirect cause is still the impact of high impact. In the face of the contradiction between the large displacement of the pump and the current displacement of the pump because of the need of subsurface in the north east block polymer promotion area, the pursuit of high-flushing can not be pursued irrespective of the regular operation of the pump, The direct and indirect impact of a failure is the amount of polymer that can not be compensated for when the parameter is multiplied. In the reference should ensure that the valve and valve seat impact speed does not exceed 60 ~ 70mm / s, according to this principle can be calculated for a variety of pump-type parameters of the pump displacement and motor pulley parameters
