一般情况下,工程机械重要运动副总成件经分解维修、重新装配后须进行必要的磨合试验,其目的是通过磨合改善零件表面粗糙度,发现压力、振动、噪声、温度和泄漏等不正常现象并消除故障。实践证明,工程机械总成磨合试验台是减少工程机械早期故障率、提高 Under normal circumstances, the construction machinery important sports sub-assembly after decomposed maintenance, reassembled after the necessary run-in test, the purpose is to improve the parts surface roughness by running in and found that pressure, vibration, noise, temperature and leakage are not normal Phenomenon and eliminate the malfunction. Practice has proved that construction machinery assembly run-in test bed is to reduce the early failure rate of construction machinery and improve
