Gantry crane factory after the run-in period FAQs

1, the wear rate of the new  bridge gantry crane  fast machines parts processing, assembly and adjustment factors, the friction surface roughness, the small contact area with the surface, uneven surface pressure conditions. The machine during operation, some parts of the surface irregularities friction fitted to each other, grinding down to the metal debris, but also as an abrasive, continue to participate in friction, but also accelerated the part mating surface wear. Therefore, run-in period is likely to cause parts (especially the mating surface) of the wear, wear faster. At this time, if the overload operation, it may cause damage to components, resulting in premature failure.
2, new processing assembly loosening of parts, there is a geometry and with the size of the deviation, the initial period, due to shock, vibration and alternating load, and heat, deformation and other factors, such as excessive wear with reasons, easy to produce the original tightening loose parts.
3, poor lubrication of components of the new assembly with the gap is small, and of the assembly and other reasons,Steel crane it is difficult to ensure uniformity with the gap, the friction surface of the oil difficult to form a uniform film, to prevent wear. Thereby reducing the lubrication performance, resulting in abnormal wear of the early parts. Cause serious friction with precision surface scratches or bite phenomenon, leading to failure.
4, the occurrence of leakage of the mechanical loosening, vibration and heat of the machine, the machine and the sealing surface of fittings, etc., there will be leakage; part casting, machining and other defects in the assembly debugging difficult to find, but because the job during vibration, shock effect, this flaw is exposed, the performance of leakage (seepage) oil (water). Therefore, the run-in period is prone to leakage.
5, faulty operation due to the structure of the machine more performance not know enough (especially the new operator),bridge gantry crane likely due to operational errors caused by malfunction, or even cause mechanical accident.
