%X 凸轮柱塞泵在液压行业中的应用十分广泛，具有瞬时功率大、极限压力高、能产生较高的压力等优点，然而凸轮柱塞泵在工作时排量较小，并且不能输送含有固体悬浮物的液体，会产生流量脉动、振动及噪声等一系列不良现象，会影响到液压传动系统的工作性能。流量脉动是影响柱塞泵工作性能的重要因素。我国对于凸轮柱塞泵的研究比较少，发展比较缓慢，目前国产泵存在压力和流量不稳定，性能不稳定的缺点，大大地制约了其发展和应用。本文对凸轮柱塞泵的流量脉动影响进行了分析，得出影响其流量脉动的主要因素是零件配合精度、弹簧的疲劳强度以及凸轮和端面的粗糙度及强度。<br />
Cam piston pump in the hydraulic industry is widely used, with the advantages of instantaneous power, high ultimate pressure and producing higher pressure, but the cam piston pump in the working displacement is small, and cannot transport liquid containing a solid suspension, will pro-duce a series of adverse phenomena such as flow pulsation, vibration and noise and will affect the working performance of the hydraulic transmission system. Flow pulsation is an important factor affecting the working performance of the plunger pump. China’s research on cam piston pump is relatively small, the development is relatively slow, the current domestic pump has the shortcom-ings of pressure and flow instability and unstable performance, greatly restricting its development and application. In this paper, the effect of flow pulsation of cam piston pumps is analyzed. It is con-cluded that the main factors affecting the flow pulsation are the precision of the material, the fa-tigue strength of the spring and the roughness and strength of the CAM and the end face.
