自环境政策制订以来,在选择液压驱动和操纵机构时,必须重视无泄漏和低噪声的要求.由于新近研制成功密封材料和紧固方法,只要设备使用恰当,泄漏是可以避免的.但是噪声至今仍是一个待解决的重要问题. 在液压系统中,对降低噪声的研究和对主要噪声源的探索至今尚未走上轨道.本文论述斜盘式轴向柱塞泵,在柱塞数的奇偶性对噪声的影响方面,进行了深入的理论研究,并配合以良好的试验,以求获得进一步的认识. Since the formulation of the environmental policy, there has been a need to focus on leak-free and low-noise in the selection of hydraulically-driven and steering mechanisms. Leakage can be avoided as long as the equipment is properly used due to the recent successful development of sealing materials and fastening methods Is still an important issue to be solved.In the hydraulic system, the study of noise reduction and the exploration of the main noise sources have not yet been on the road.This paper discusses the swash plate axial piston pump, The impact of noise, conducted in-depth theoretical research, and with a good experiment, in order to obtain further understanding.
