5 techniques for extending the life of wheel loaders
Apart from excavators, I think the most common thing we see in our daily life is loaders. I don't know if you guys found such a phenomenon? Now a large part of the domestic excavator is a joint venture brand, and loaders are mostly independent brands. It is very important for us to do well the maintenance and maintenance of the loader while we improve the level of the machine made in china. The market also exists such a phenomenon, such as the same is 5000 hours of machine, a possible quality is very good, some may have no way, this phenomenon is related to the condition in addition to the loader, and the machine in the usual course of the maintenance and maintenance of.
So, today Xiaobian talk about the loader repair and maintenance of those things!
1., adhere to the "two guarantees and Three Guarantees" system
Person, machine, bag, bag bag storage, use maintenance, loader operator to achieve the "three" (understand the structure, understand the principle and understand the performance), "four" (use, maintenance, inspection, remove common breakdown). The correct use of the loader, the strict implementation of security procedures, the implementation of target cost management of mechanical equipment, the operator and economic benefit of the loader use fee (such as fuel oil costs, maintenance costs, maintenance costs, material costs, fees and other tools) hook, variable loader driver passive maintenance equipment for active maintenance maintenance.
2. reduce the invisible wear caused by environmental climate to Loaders
That is, to reduce the impact of environmental factors on its service life. As the construction machinery is mostly open-air operation, the operation site often changes, so its performance is affected by the temperature, environment, climate and other factors of the operation site. Long term fixed operation of the machine, must have downtime (shed), or take cover, the use of wood pad maintenance measures to reduce the sun, rain, rust caused by the invisible wear. Many construction units ignore the influence of environmental factors on the use of machinery (environmental temperature is too low, but also cause disastrous consequences to the machine). Failure to take appropriate protective or adaptive measures, resulting in reduced mechanical performance, shorten service life, and even lead to accidents.
3. the regular maintenance of loaders is the key to prolong the service life
"The Ministry of transportation construction and maintenance machinery warranty regulations" on loader maintenance are clearly defined, however, many construction units to a tight and heavy task, often ignore that mechanical maintenance work, normal operation, no fault, no need to stop maintenance. The accident caused by machinery which buried the day after the danger. Because maintenance can eliminate mechanical hidden trouble, if not timely maintenance, often will make mechanical equipment appear big fault, and even personnel injury accident. This will not only increase maintenance costs, but also delay construction period.
4. adopt advanced mechanical detection and other auxiliary means of maintenance
The mechanical maintenance work is an important link to prolong the service life of the machinery. Reasonable maintenance method can effectively prolong the service life of the construction machinery. According to the relevant statistics, the use of advanced state monitoring means can reduce the maintenance cost of 25% ~ 50%, the failure rate decreased by 75%, and can extend the service life of the machine.
5. low cost rapid maintenance method
The "low-cost rapid repair method" proposed by the mechanical industry is also an effective way to extend the service life of machinery. This method, in addition to the mechanical design using the maintainability design and improve mechanical maintenance, maintenance in practice also can adopt the following methods: one is the part of transposition, many parts of construction machinery such as bulldozers, excavators track pin, diesel engine cylinder, in operation often under uniaxial load, resulting in wear not balanced, if timely replacement of parts by unbalanced load position, make them wear leveling, can prolong the service life. Two is the use of advanced brush plating and adhesive repair technology, but also quickly and locally repair defective parts. Such as wear-resistant surfacing, spraying diamond electroplated coating, magnetic plating, laser plating, etc..
Sum up:
As our life loader used in high frequency machine, its use in the process of maintenance is very important, the machine is actually not a pile of cold steel, not just for our money machine, daily maintenance, the machine can serve us better.
