CA51D振动压路机是DYNAPAC公司生产的由变量泵、前钢轮变量（高、低速两挡）马达及后胶轮定量马达组成的全液压驱动压路机。在使用过程中,突然出现无法行走的现象。检查油箱,油品正常;当拆检回油滤油器时,发现有大量铜屑,估计为泵或马达元件出现磨损所致。在放油过程当中,发现泵的进油管处有大块铜片,此状况表明泵或马达的滑靴或缸体铜套已损坏。
CA51D vibratory roller is produced by DYNAPAC variable pump, the former steel wheel variable (high and low speed two gear) motor and the rubber tire quantitative motor composed of full hydraulic drive roller. In the process of using, suddenly appeared unable to walk phenomenon. Check the fuel tank, oil normal; when disassembled back to the oil filter, found a large number of copper scrap, estimated to pump or motor components due to wear and tear. During drain, a large piece of copper was found at the inlet of the pump, indicating a damaged pump or motor shoe or cylinder sleeve.
