How excavator new machine Running? Workshop was opened from an excavator that moment, it has life, it also began a lifetime. So this time, we should pay attention to is the run of the new machine, this time we called run-in period. We usually see a very interesting phenomenon: if a car, especially private cars, people tend to be very concerned about the use of car break-in period, can not open soon, not Kaiyuan, always on tenterhooks for fear of a vehicle break-in period Running a bad influence future performance, but for excavators for it, do not get such care. The reality is that the bought back the excavator, people first thought is to seize the time to make money. Since the new machine is also not severely with, anyway, warranty period, the results are often overloaded machine, early failures occur frequently, many tales of blocked heart of things a small hook machine, the service life of the machine is also greatly reduced. But the fact is due to the new machine parts and other just opened, rough surface, the machine is running friction between concave and convex portions, wipe off the metal debris and participation continue rubbing, so part of this period is very easy to wear second-hand hook machine price, if In this case overload, it is easy to damage parts appear early failure. Therefore, buy a new excavator, the first amount of work to ensure proper, do not work overtime, running workloads period should not exceed 60% of the rated working load, long continuous operation to prevent the machine overheating occur. Also, do not get on the train to open a small hook machine prices, check the instrument panel, oil, sealing, each class should be greased for lubrication points. Remember, only it is good, it can best work for you.泰安嘉 and Heavy Machinery Co., excavator maintenance of taboos: a cylinder gap measure not allowed in the measurement of the cylinder gap sized hook machine, failed to measure the vertical direction of the piston skirt piston pin hole in, measured in other directions. The structural characteristics of the aluminum alloy of the piston is small great as a cone, and the skirt portion is oval cross section, so that the gap in the circumferential direction of the cylinder is not equal. When measuring provisions to the long axis of the ellipse gap prevail, ie measuring clearance between the piston skirt perpendicular to the direction of the piston pin hole. This measure is more convenient, accurate, and in reciprocation, the piston skirt due to the effect of a vertical lateral pressure in the direction of the piston pin hole and wear large, so measuring cylinder gap, should be perpendicular to the piston skirt piston direction of the pin hole measurement. Pistons fire heating the piston and the piston pin is an interference fit, so when installing piston pins, piston thermal expansion should be, then, some maintenance personnel will be on the fire directly heating the piston. This approach is very wrong, because all parts of piston uneven thickness, will not the same degree of thermal expansion and contraction, flame heating causes the piston to uneven, easily deformed; piston surface will be attached to the charcoal, reduce piston life. If the piston reaches a certain temperature, natural cooling, the microstructure would have been greatly reduced damage and wear, their life will be significantly shortened. When installing the piston pin, the piston can be placed in the hot oil uniformly heated to slow expansion, must not use direct fire heating.泰安嘉 and Heavy Machinery Co., Ltd., Jilin small hook machine | Kerry and Heavy | domestic small hook machine provided by 泰安嘉 and Heavy Machinery Co., Ltd ..
