摘　　要：目前,高压柱塞泵普遍采用滑靴的柱塞结构,滑靴不仅增大了与斜盘的接触面,减小了接触应力,而且其封严带结构,使滑靴与斜盘表面之间形成一层润滑油膜,极大地降低了滑靴-斜盘摩擦副之间的摩擦损失,提高了整泵机械效率。柱塞泵最高工作压力不同,滑靴封严带也随之采用不同结构。该文通过故障分析、理论研究和仿真计算滑靴副PV值,并结合试验验证的方式,阐述了3种不同封严带结构的滑靴在工程实际中的应用。At present,the high-pressure plunger pump plunger structure of generally used sliding boots,sliding boots not only increases and the contact surface of inclined plate,reducing the contact stress,and its seal structure,the sliding boots and form a layer of oil film between the swash plate surface,greatly reduce the sliding boots a swash plate between the friction pair of friction loss,improve the whole pump mechanical efficiency.The highest working pressure of the plunger pump is different,and the sealing belt of the slipper also adopts different structure.In this paper,through fault analysis,theoretical research and simulation,PV value of slipper pair is calculated,and combined with the way of test verification,the application of three kinds of slipper with different sealing belt structure in engineering practice is expounded.
