The use of engineering machinery, often in some harsh environment conditions, and because of the influence of material and technology, and that factors such as aging parts, construction machinery failure in use will inevitably appear various. In the construction process, if the construction machinery failure, not only will affect the normal construction schedule The use of engineering machinery, often in some harsh environment conditions, and because of the influence of material and technology, and that factors such as aging parts, construction machinery failure in use will inevitably appear various. In the construction process, if the construction machinery failure, not only will affect the normal construction schedule, resulting in unnecessary financial losses, but also reduce the service life of construction machinery. How to prevent the breakdown of construction machinery has become a problem frequently discussed by construction units. If we can correctly analyze the causes of failure, take targeted preventive measures and effective damage speed of mechanical parts is to slow down, can effectively prevent the continued failure, prolong the service life of the machine. First, try to reduce the impact of harmful factors 1, reduce the influence of continued impurities Mechanical impurities are generally referred to as dust, soil and other non-metallic materials and construction machinery in the process of lifting some metal chips, wear products and so on. 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
