Loaders and maintenance characteristics and apply
1 wear faster
Since the new machine parts processing, assembly and adjustment factors, the friction surface roughness, with the surface contact area is small, 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 and continue to participate
as an abrasive friction, more accelerated wear of the mating surfaces of the parts. Therefore, run-in period is likely to cause parts (especially the mating surface) of the
wear, wear faster. At this time, if the loader overload operation, it may cause damage to components, resulting in premature failure.
(2) poor lubrication
Parts of the new assembly with the gap is small, and of the assembly and other reasons, it is difficult to ensure uniformity with the gap, lubricant (grease) on the friction
surface is not easy 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.
New processing and assembly of parts, the presence of geometry and with the size of the deviation, the initial period, due to shock, vibration and alternating load, and heat,
deformation and other factors, coupled with excessive wear and other reasons, easy to make the original tightening of loose parts.
4 leakage occurs
Loosening of the mechanical vibration of combined heat the machine, the machine and the sealing surface fitting logout leakage phenomenon, part casting, machining and other
defects in the assembly debugging difficult to find, but during the operation of the vibration, shock role of this flaw is exposed, the performance of the drain (infiltration)
(water), therefore, prone to leakage run-in period.
Loader application and maintenance
1 Because of construction machinery is a special vehicle, operating personnel should receive factory training, guidance, and the machine structure, properties have a full
understanding and get some experience in the operation and maintenance before operating the machine. Manufacturers to provide "product maintenance manual" is the operator to
operate the equipment necessary information before operating the machine, be sure to read the "maintenance manual", according to the requirements of operation and maintenance.
2 Note that the run-in period workload, run-in period should not exceed half of the workload of 60% of the rated working load, and to arrange for appropriate workload, long
continuous operation to prevent the machine overheating caused by the occurrence of the scene.
3 Note that frequently observed instrumented, abnormal should be excluded promptly stop in reason is not found, the fault is not excluded should be stopped before operation.
4 Note that regular checks of lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water) bit and the quality and attention to check the tightness of the machine.
Inspection found that too much water is missing, you should analyze the reasons. Meanwhile, the lubrication points should be strengthened lubrication is recommended run-in
period, the class must be on the portable conveyor lubrication point greasing (except for special requirements).
5 Keep the machine clean, adjust, tighten loose parts to prevent loosening due to increased wear and tear parts or cause parts missing.
6 run-in period is over, deal with the mandatory machine maintenance, inspection and adjustment of work to do, while paying attention to fluid replacement.Flat belt conveyor
