提高装载机液压系统的压力可以提高液压系统的可靠性，降低成本，提高产品在市场上的竞争力。以ＺＬ５０装载机为例，采用两种不同的方案，对提高压力前后的液压系统的性能指标进行了比较和经济性分析，论述了目前提高国内装载机液压系统工作压力的可行性。
Increasing the pressure of the loader hydraulic system can improve the reliability of the hydraulic system, reduce costs and improve the competitiveness of products in the market. Taking ZL50 loader as an example, two different schemes were used to compare the performance of the hydraulic system before and after the pressure increase and the economic analysis. The feasibility of improving the working pressure of the domestic loader hydraulic system was discussed.
