小型挖掘机输入功率不敷的缘故缘故原因!

  小型挖掘机的倡议机输入功率不敷。遵从如下:运转空时正常运转。
  The engine output power of small excavator is insufficient. The performance is as follows: normal operation at runtime.
  在I、III运转时,节流阀自动回到1150-1250r/min范围,回到1500-1800r/min,泵压25Mpa,冒黑烟;空转速率低,停机排放白烟;燃油回流管过热。
  During the operation of I and III, the throttle valve automatically returns to 1150-1250r / min, 1500-1800r / min, pump pressure 25MPa, black smoke; idle speed is low, stop and discharge white smoke; fuel return pipe is overheated.
  孕育发生这些标题的缘故缘故原因包括:燃油质量差、燃油压力低、气门间隙不准确、汽缸运转不正常、燃油放射正时不敷、燃油流量不敷、进气体系泄漏、刹车和运转。活塞杆粉碎,涡轮增压器聚集。
  The causes of these problems include poor fuel quality, low fuel pressure, incorrect valve clearance, abnormal cylinder operation, insufficient fuel injection timing, insufficient fuel flow, intake system leakage, braking and operation. Piston rod damaged, turbocharger deposited.
  依据从约莫到庞大的步伐:起首查抄机油可否合格,并运用合格的燃料。查抄倡议机气缸可否变乱正常,各气缸可否变乱正常。查抄回阀,查抄气门间隙,并查抄进气阀的宽容倡议机气门间隙查抄燃油压力可否过低,回油可否过高或前去油压可否足以调停排气阀间隙。接上去,依据呆板喷油正时和燃油量控制指令调停喷油正时和燃油量。
  Follow the steps from simple to complex: first check whether the oil is qualified and use qualified fuel. Check whether the engine cylinder works normally and whether each cylinder works normally. Check the return valve, check the valve clearance, and check the tolerance of the intake valve engine valve clearance check whether the fuel pressure is too low, whether the return oil pressure is too high or whether the return oil pressure is enough to adjust the exhaust valve clearance. Next, adjust the injection timing and fuel quantity according to the machine injection timing and fuel quantity control command.

  小型挖掘机倡议机水温较高,经以上查抄后,呆板将再次举行测试。当发现i-iii块变乱时,排气正常,转速和泵压低。在第三档变乱时,刹车不动。加注后采取节流阀控制,大型泵的倡议机转速和泵压增大,但出现黑烟。这约莫是由于手动应用的油门控制,招致不匀称加油。再查抄一下刹车。起首,查抄刹车电路。结果正常。拆下刹车,发现内里有尘土。查抄并洗濯零件,陈设查抄过的刹车,然后再对呆板举行测试,以确保拦阻曾经消弭。然后互换新的刹车,测试呆板,观察种种齿轮,倡议机转速,泵压,排气可否正常。
  The engine water temperature of small excavator is high. After the above inspection, the machine will be tested again. When I-III block is found to work, the exhaust is normal, and the speed and pump pressure are low. When working in the third gear, the brake does not move. The engine speed and pump pressure of the large pump increase, but there is black smoke. This may be due to manually operated throttle control, resulting in uneven fueling. Check the brakes again. First, check the brake circuit. The results were normal. Remove the brake and find dust inside. Check and clean the parts, install the checked brake, and then test the machine to ensure that the fault has been eliminated. Then replace the new brake, test the machine, and observe whether various gears, engine speed, pump pressure and exhaust are normal.
  先容了小型挖掘机倡议机产量不敷的缘故缘故原因及处置处分要领,盼望对您有所资助。
  This paper introduces the causes of the insufficient output of small excavator engine and the treatment methods, hoping to help you.
