Road machinery and equipment rental equipment are generally not cheap, often tens of thousands. How to keep the mechanical equipment working normally and prolong the working life is particularly important. The following editor will take you to understand the methods of prolonging the service life of pavement machinery and equipment. Let's first understand the key factors affecting the service life of equipment, namely: temperature, magazine, corrosion and load.
Each component has its own applicable temperature range. Too high or too low temperature will affect the performance. For example, the use range of hydraulic oil in hydraulic transmission system is 30~60 ℃, lower or higher than this temperature range will accelerate the wear of parts.
Mechanical equipment impurities generally refer to non-metallic substances such as dust, gravel and metal debris generated during the use of mechanical equipment. Once these impurities enter the machine, they will not only accelerate the wear of parts, but also scratch the mating surface and destroy the lubricating oil film, which will eventually lead to the temperature rise of parts and the deterioration of lubricating oil.
The long-term erosion of mechanical equipment by rain and air will not only affect the normal work of the mechanical surface, but also corrode the internal parts of mechanical equipment, accelerate mechanical wear and increase the failure rate of equipment.
The engine working under normal load has low failure rate and long service life. On the contrary, if the engine is overloaded, the failure rate will increase significantly, and the service life will also be reduced compared with the design index. The wear of machines that are often in a wide range of load changes is greater than that of machines that work continuously and stably.
Operation specification for this purpose, during the use of construction machinery:
First, it is necessary to prevent overload operation at low temperature and normal operation at low-speed pre temperature stage, so that the machine can run or work after reaching the specified temperature, and do not ignore its important role because there are no problems at that time;
Second, the machine should be prevented from running under high temperature. During the operation of the machine, the values on various thermometers should be checked frequently, and if problems are found, the machine should be shut down immediately for inspection, and if faults are found, they should be eliminated in time.
Third, check the working condition of the cooling system. For water-cooled machinery, check and add cooling water before daily work; For air-cooled machinery, the dust on the air-cooled system should also be cleaned regularly, and the cooling air duct should be unblocked.
That's all for sharing the methods of prolonging the service life of road machinery and equipment leasing. I wonder if you are satisfied with Xiaobian's answers? If you need to add or want to know something, please follow our website http://www.ycgjglcl.com Leave a message for Xiaobian.
