Prevent engineering machinery fault six-step

The use of engineering conveyor chain, often in an environment in some situations, and the materials, technology, components and the influence factors of thought, engineering Conveyor Chain in use will inevitably occur various fault. In the construction process and construction machinery fault, if not only affects the normal construction schedule and cause unnecessary expenditure, also can reduce loss of engineering machinery service life. How to prevent engineering machinery fault became construction unit often talked about. If can correctly analyzes all kinds of reasons, take effective measures, the pertinence, try to slow speed of mechanical parts, can damage to effectively prevent the fault, prolong the using lifetime.
A, trying to reduce the harmful factors
1 and reduce the influence to impurity
Mechanical impurities commonly refers to dust, soil etc. Nonmetal material and engineering Conveyor Chain in use process ZiSheng some metals, wear products, etc. These impurities, once you enter the machinery, the coordination between mechanical harm its surface is very big, not only makes the relative motion is accelerated, the block out, and will wear parts with surface, scratch, parts of the oil film temperature, fluid oil.to. According to the measurement of mechanical impurities, lubricating oil to 0.15, the engine piston wear 2.5 times larger than normal, When entering impurities particle rolling bearings, their life will reduce 80 to 90 percent. Therefore, to work in environments and conditions of complex engineering machinery, place to use high quality, complete parts and lubricating oil, grease, block harmful impurities. 2 to do a good job site, ensure the mechanical protection agencies can work normally, prevent various impurities into machinery. The malfunction of mechanical, try to place regular repair repair. Field repair, also want to protective measures to prevent field repair, replacement parts into mechanical impurities such as former by dust pollution.
2 and reduce corrosion function
Metal surface with the surrounding medium happening conveyor chain or electrochemical reactions and damage phenomenon called corrosion. This will not only affect corrosion function of normal appearance mechanical equipment, and corrosion machine to spare. If rain in the chemicals, air through mechanical parts such as external channel, aperture machine into mechanical components, accelerate corrosion and abrasion increase mechanical fault. Because of the corrosion are sometimes invisible. Touched, easily ignored by people, and its harmfulness bigger. In use, management and operation personnel according to the weather, air pollution situation, take effective measures, reduce the effective measures of reducing chemical corrosion, mechanical, emphasis is to prevent rain and chemical composition of machinery in the air.
3 and reduce the influence of the temperature of
In work, all parts of temperature have their normal range. As the temperature of cooling water 80 to 90 degrees, hydraulic transmission system temperature of hydraulic oil is 30 ~ 60 degrees, the more or less will accelerate the scope of wear parts, materials, fluid oil.to changes, etc. Experiment shows that the various engineering Conveyor Chain gear and bearing in - 5 ° c in operation in 3 degrees than the lubricating oil, abrasion will increase 10-12 times. But when the temperature is high, and will accelerate the lubricating oil temperature, such as bad 55 ~ 60 ° checked, the oil temperature rise every 5 degrees Celsius, oil oxidation rate will be doubled. Therefore, engineering machinery in use process, to prevent the low-temp seams, ensure the normal temperature phase advance low-speed mechanical operation, make specified temperature after driving or work, not because it was not neglect the important problems do, To prevent mechanical under high temperature operation, mechanical operation process of the thermometer should always check the value, immediately stop check and problems found that even eliminate malfunction. To find a reason, but still made by processing machinery in spite of work. In peacetime work, must check the working conditions of the cooling system. In daily work, water-cooled Conveyor Chain must check, add water, The air-filled type of mechanical, also want to regular cleaning the dust on the cooling air cooling, ensure unblocked.
