Wear speed because of the new machine parts processing, assembly and adjustment, the influence of such factors as the friction surface is rough, cooperate with the surface contact area is lesser, uneven surface pressure condition. Machine in the process of running, concave and convex part chimeric friction each other on the surface of the parts, grinding of metal debris fell down, and as an abrasive, continue to participate in friction, accelerate the abrasion on the surface of the parts with more. The running-in period, therefore, likely to cause parts ( Especially with surface) The wear and wear speed. At this time, if the overload operation, may cause the damage of the parts, early failure. Bad lubrication because of the new assembly parts fit clearance is small, and due to reasons such as assembly, it is difficult to guarantee the uniformity of fit clearance, lubricating oil, Fat) Not easily formed in the friction surface oil film evenly and to prevent wear and tear. Reducing lubrication performance, causing the early abnormal wear and tear parts. Caused serious precision of friction surface scratch or bite phenomenon, lead to failure. Loose new processing and assembling parts, geometry shape and dimension deviation, exist at the beginning of the use, due to alternating load such as shock, vibration, and the influence of factors such as heat, deformation, and the wear too fast, easy to make the original loose fastening parts produced. Leakage phenomenon happened because of loose parts of the machine, vibration and heat, the effect of sealing face of the machine and the pipe joint, there will be a leakage phenomenon; Some defects such as casting, machining, assembly and debugging is hard to find, but due to the vibration and impact in the process of operation, this kind of defects are exposed, show the leakage ( Permeability) Oil ( Water) 。 Period, therefore, prone to leakage phenomenon. Error due to the more understanding of the structure of the machine, the performance is not enough ( Especially the new operator) , easy fault caused by error, and even cause mechanical accident. Due to mechanical engineering is a special vehicle, the operating personnel should receive training and guidance from the manufacturer, have full knowledge of the structure of the machine, performance, and get some experience before operating the machine for operation and maintenance. With the: 'peration &maintenance manual of manufacturers to provide products, are the essential data of operating equipment, operator before operating the machine, be sure to read the instruction in operation and maintenance, according to the specification requirements for operation and maintenance. Pay attention to the work load period, the running-in period of working load generally not more than 80% of the rated load, and to arrange suitable work, prevent the machine from overheating caused by long time continuous operation. Pay attention to always observe the instructions in the instrument, abnormal, should be ruled out, to stop the reason was not found, the fault before has not been ruled out, should stop work. Pay attention to regularly check the oil, hydraulic oil, coolant, brake fluid, and fuel oil ( Water) And quality, and pay attention to check the sealing of the engine. Examination found that oil and water without too much, cause should be analyzed. At the same time, should strengthen all lubricating points lubrication, suggest in the running-in period, per shift to inject grease lubrication points ( Except special requirement) 。 Keep the machine clean, timely adjustment, tighten loose parts, to prevent the wear of intensified due to loose parts or parts in the loss. End of the period, the machine for maintenance, inspection and adjustment work, at the same time pay attention to the oil replacement.
