How to do the maintenance of mining machinery parts?
Reduce the influence of mechanical impuritiesMechanical impurities are generally referred to as dust, soil and other non-metallic materials and mining machinery in the process of its own production of a number of metal debris, wear products, etc.. Once these impurities into the internal machinery to match surface mechanical, its harm is great, not only make out the relative motion block, accelerated wear parts, and will scratch with the surface, destruction of the lubricant film, make parts temperature and oil deterioration.For the mining machinery work in harsh environment and complex condition places, one is to use high quality, supporting components and lubricating oil and grease, the source block harmful impurities; two to do a good job of mechanical protection work site, ensure the corresponding mechanism to work, to prevent the impurities from entering the internal machinery. For failure of machinery, as far as possible to the formal repair site repair. Site repair, but also to do a good job of protection measures to prevent on-site repair parts replaced by dust and other impurities before entering the machinery.
Reduce all kinds of corrosionThe destruction of a metal surface by chemical or electrochemical action with its surrounding medium is called corrosion. This corrosion will not only affect the normal work of the machinery and equipment, but also corrode the parts inside the machine. Such as rain, air chemicals and other mechanical components through the external channel, gap and so on into the machinery, corrosion of machinery parts, accelerate mechanical wear, increase mechanical failure. Because of this corrosion is sometimes invisible and can not be touched, easily overlooked, and therefore more dangerous.In use, management and operating personnel according to the prevailing local weather conditions and air pollution, to take effective measures to reduce the influence of chemical corrosion on the mechanical, is focused on preventing intrusion of mechanical and chemical composition of rainfall in the air, as far as possible to reduce the rain.
Ensure normal working loadThe size and nature of the working load of the mining machinery have an important influence on the mechanical loss process. Generally speaking, the wear of parts increases proportionally with the increase of load. When the load on the part is higher than the average design load, the wear will increase. In addition, when other conditions are the same, the stable load is smaller than the dynamic load, the fault is less, and the life is low.Under normal load, the engine has a low failure rate and a longer life. On the contrary, the overload engine will increase the failure rate and reduce the life expectancy of the engine. Mechanical wear is often greater than that in a large range of load changes
Mining machinery belong to large-scale equipment, the purchase of new equipment and frequent replacement parts will consume a lot of money, and affect the enterprise production schedule, therefore, how to correct for mine equipment maintenance so as to prolong the service life of the equipment is very important. The following is the Aupu mining machinery for you to collate how to maintain mechanical parts
