qx 51-125/51-125 r库存 力士乐泵是输送流体或使流体增压的机械。它将原动机的机械能或其他外部能量传送给液体，使液体能量增加。力士乐泵主要用来输送水、油、酸碱液、乳化液、悬乳液和液态金属等液体，也可输送液、气混合物及含悬浮固体物的液体。力士乐泵通常可按工作原理分为容积式力士乐泵、动力式力士乐泵和其他类型力士乐泵三类。除按工作原理分类外，还可按其他方法分类和命名。如，按驱动方法可分为电动力士乐泵和水轮力士乐泵等；按结构可分为单级力士乐泵和多级力士乐泵；按用途可分为锅炉给水力士乐泵和计量力士乐泵等；按输送液体的性质可分为水力士乐泵、油力士乐泵和泥浆力士乐泵等。按照有无轴结构，可分直线力士乐泵，和传统力士乐泵。 1.容积式力士乐泵
靠工作部件的运动造成工作容积周期性地增大和缩小而吸排液体，并靠工作部件的挤压而直接使液体的压力能增加。
根据运动部件运动方式的不同又分为：往复力士乐泵和回转力士乐泵两类。
根据运动部件结构不同有：活塞力士乐泵和柱塞力士乐泵，有齿轮力士乐泵、螺杆力士乐泵、叶片力士乐泵和水环力士乐泵。
2.叶轮式力士乐泵
叶轮式力士乐泵是靠叶轮带动液体高速回转而把机械能传递给所输送的液体。 r902050455 a11vo190lrdh1+a11vo190lrdh1
