1.熨平板伸缩系统组成熨平板的伸缩过程是熨平板基础段保持不动,左、右伸缩段在伸缩液压缸的带动下,随液压缸行程的变化而相对基础段发生宽度变化。其液压系统原理如图1所示。主要由油箱、齿轮泵、溢流阀、三位四通电磁阀、分流阀、冷却器和左、右伸缩液压缸等部分组成。
Screed retractable system screed scalable process is the basic section of the screed remain stationary, left and right telescopic section in the telescopic cylinder driven, with the cylinder stroke changes relative to the basic section of the width changes. The hydraulic system principle shown in Figure 1. Mainly by the fuel tank, gear pump, relief valve, three four-way solenoid valve, diverter valve, cooler and left and right telescopic hydraulic cylinder and other components.
