摊铺机液压系统工作性能是否稳定、可靠,是提高摊铺施工质量和效率的关键因素之一。本文针对某型轮式摊铺机液压缸响应缓慢的原因进行分析,并提出改进方案。1.液压缸油路的缺陷某型轮式摊铺机为实现其3组液压缸独立、准确运行功能,采用的液压缸油路如图1所示。优先阀具有提供恒定流量且控制精准的特点,故在该液压缸油路中设置了3个优先阀,并将其串联使用,各个优先阀的优先口和旁通口均接入可
Paving machine hydraulic system performance is stable and reliable, is to improve the quality and efficiency of pavement construction, one of the key factors. In this paper, a type of wheel paver hydraulic cylinder response to the reasons for the slow analysis and propose improvements. 1 hydraulic cylinder defects of a certain type of wheel paver in order to achieve its three independent, accurate hydraulic cylinder function, the use of the hydraulic cylinder circuit shown in Figure 1. Priority valve has to provide a constant flow and precise control of the characteristics of the cylinder in the oil so set up three priority valve, and its use in series, the priority of each priority valve and the bypass port are accessible
