轴向柱塞泵在液压传动系统中已得到了广泛应用。由于科学技术的迅速发展,要求提高轴向柱塞泵性能和使用寿命的呼声也越来越高。而影响性能和使用寿命的主要障碍是摩擦副磨损急剧,容易产生胶合现象(胶合的概念和过程与齿轮传动基本一样)以及容积效率很快降低。为了寻求解决的途径,我们初步分析了产生这些问题的原因及解决的办法,并从提高 ZB40泵的压力级和转速着手,在不改变原有毛坯和工装的前提下,经过反复的试验研究和改进,把额定压力由原来的210公斤力/厘米~2提高到了250公斤力/厘米~4,最高转速由原来的2500转/分提高到了3000转/分,目前已运
Axial piston pumps in the hydraulic transmission system has been widely used. Due to the rapid development of science and technology, demands for increasing the performance and service life of axial piston pumps are also getting louder and louder. The main obstacle to performance and service life is the rapid wear of the friction pair, which tends to cause gluing (the concept and process of gluing are basically the same as the gear drive) and the volumetric efficiency is rapidly reduced. In order to find a solution to the problem, we initially analyzed the causes and solutions to these problems. From the point of improving the pressure level and speed of the ZB40 pump, without changing the original blank and tooling, after repeated experimental studies and Improvement, the rated pressure from the original 210 kg / cm ~ 2 increased to 250 kgf / cm ~ 4, the maximum speed from the original 2500 rev / min increased to 3000 rev / min, has been shipped
