本文从分析现有闭路式柱塞泵分类入手,在对现有闭路式柱塞泵中各种配油方式进行比较的基础上提出了一类采用新型配油方式的柱塞泵—开路式配油柱塞泵。这类柱塞泵可以制成不同输出、不同变量、不同定量、不同控制方式的多种不同形式的多输出柱塞泵。因此,这类柱塞泵不但可以满足一般要求,而且可以满足特殊的要求。既可以制成轴向、又可以制成径向,还可以制成其它形式的。这种柱塞泵有如下特点:无回油、可自冷、可串并联、可多输出、压力高、效率高、寿命长等等。国内外对径向联合配油开路式原理已有研究而本文则提出了轴向联合配油开路式原理并着重论述了该种泵的工作原理及其基本组成。
Based on the analysis of the existing closed-circuit piston pump classification, based on the comparison of the existing oil-in-pipe pumps in the closed-circuit piston pump, a new type of piston pump with oil distribution system Oil plunger pump. This type of piston pump can be made into different output, different variables, different quantitative, different control methods in many different forms of multi-output piston pump. Therefore, this type of piston pump can not only meet the general requirements, but also to meet the special requirements. Can be made of axial, but also made of radial, but also can be made in other forms. This plunger pump has the following characteristics: No back to the oil, since the cold, can be series and parallel, can be more output, high pressure, high efficiency, long life and so on. At home and abroad, the open joint principle of radial joint oil distribution has been studied. In this paper, the principle of open joint of axial joint oil distribution is put forward and the working principle and basic composition of this kind of pump are emphatically discussed.
