根据我们使用WY100挖掘机的经验,液压系统常见故障及排除方法可归纳为以下几条: 1.启动发动机,打开压力表开关并观察压力表读数。2.左或右压力表没有压力时,看油箱是否有油(若油不足,可加足)及油箱开关是否打开(若未打开,可打开)。3.右(左)边压力表有压力而左边(右边)没有压力,可松开油泵左边(右边)的放气螺丝,排除空气。若好转,说明有空气,可继续排气;若仍无压力,说明油泵有故障。4.如果左边压力表有压力,可扳动第二组阀的操纵杆(控制大臂、小臂、左行走、推土);如右边压力表有
According to our experience with the WY100 excavator, common faults and remedies for hydraulic systems can be summarized as follows: 1. Start the engine, turn on the pressure gauge switch and observe the pressure gauge reading. 2. When there is no pressure on the left or right pressure gauge, see if there is oil in the fuel tank (if the oil is not enough, add enough) and the fuel tank switch is turned on (if it is not open, it can be turned on). 3. When the pressure gauge on the right (left) side is under pressure and there is no pressure on the left (right side), the bleeder screw on the left side (right side) of the pump can be released to remove the air. If it improves, it means that there is air, and the exhaust can continue; if there is still no pressure, it means that the oil pump is faulty. 4. If there is pressure on the left pressure gauge, you can move the levers of the second group of valves (control the boom, the jib, walk left, push the soil); if the pressure gauge on the right has
