1.Cutting of various corrosion effect

The metal surface by chemical or electrochemical effect with the surrounding medium attack damage according to the appearance of corrosion. The corrosion effect not only affects the normal operation of surface mechanical equipment, and internal corrosion to the mechanical parts. Such as rain, the chemicals in the air after mechanical parts of foreign channels, and crack into the machinery, mechanical parts, internal corrosion speed up mechanical wear and tear, add a mechanical defect. Because the corrosion effect is sometimes invisible, scratching, brief were ignored, thus its damaging. In use, disposal and operating personnel should according to local weather conditions, the air pollution situation at that time, and selects the useful way to reduce the chemical corrosion effect on the mechanical, the key is to avoid the rain and the invasion of the chemical composition of mechanical in the air.

2.To ensure the normal operation load

Engineering machinery operation range and nature of the load loss of mechanical process has important influence. Generally speaking, the wear parts along with the adding of load into share to add. When parts accept load is higher than the homogeneous solution load, the wear and tear will be worse. Other, other conditions being the together, safe than wear under dynamic load, the load is small, less defect, the stature is low. Experiments indicate that the engine under unsafe load operation and safe operation under load mutatis mutandis, the cylinder wear will be increased 2 times. Under normal load operation of the engine, its defects attack rate is low, and the full extension. On the contrary, the overload operation of the engine, defect attack rate significantly increased, life spans than cutting plan policy. Often in a big plan load changes mechanical wear quantity is greater than the continued safe operation of machinery
