| Unlike other equipment, machinery will lose its original use value after a certain period of time. On the contrary, the more durable the construction machinery is, if you maintain it properly, no matter how long you use it, it will run normally as the first time. However, the premise is that you do well in daily maintenance work. So how to do its maintenance work well? Today I will tell you about the details of maintenance. I. Avoiding Impurities In the operation of construction machinery, some dust in the air, gravel in the working environment and impurities in the air are usually mixed in. Of course, it is not excluded that part of the metal impurity precipitation caused by wear and tear of the machine itself. Once these impurities are mixed into mechanical parts, bad phenomena such as deterioration of oil, damage of hydraulic system, failure of lubricating oil, etc. will occur. It will directly affect the normal use of machinery. Therefore, oil quality, matching parts and lubricants should be used in the use of construction machinery. Different oils are selected according to different seasonal environments. Guarantee the normal use and maintenance of parts and components. Do a good job of oil tank sealing, fundamentally prevent the air from entering, and then prevent the oxidation of oil. In addition, in the daily work site maintenance, we should do a good job in cleaning the surrounding environment, pay attention to cleaning the obvious sand and stone and unnecessary impurities in the surrounding environment, ensure the car body around clean, prevent secondary pollution in the maintenance process. II. Temperature Impact Different parts have different constant temperatures, such as cooling water 80-90 C, hydraulic oil 30-60 C in hydraulic transmission system. If parts lose their constant temperature in daily operation, it will destroy their performance, cause oil deterioration, and cause bad wear and tear of parts. For example, when the main transmission gears and bearings are at - 5 C, their lubrication degree and the wear degree of lubricating oil at 3 C will increase by 10 - 12 times; but when the oil temperature exceeds 55 - 60 C, the oxidation rate of oil will increase by twice with the increase of oil temperature by 5 C. Therefore, in the use of construction machinery, it is necessary to ensure the normal operation of the low-speed preheating stage and pay attention to preventing the machine from overloading at low temperature, and then carry out routine work when the machine reaches the required temperature. Secondly, in order to prevent the machine from running at high temperature, we should always observe the values on the thermometers during the operation and use of the machine. Once we find out the problem, we should stop working and check it immediately. Do a good job of oil tank sealing, fundamentally prevent the air from entering, and then prevent the oxidation of oil. In addition, in the daily work site maintenance, we should do a good job in cleaning the surrounding environment, pay attention to cleaning the obvious sand and stone and unnecessary impurities in the surrounding environment, ensure the car body around clean, prevent secondary pollution in the maintenance process. 3. Corrosion Because the construction machinery is composed of metal frame, if we do not pay attention to the daily anti-corrosion work, it is very easy to rust in the outdoor complex working environment. Therefore, different types of work and different degrees of work should be arranged according to different weather conditions in the operation process, especially the erosion of rainwater on machinery. 4. Reasonable working load Because of the particularity of the construction machinery industry, the nature of its work is usually complex and heavy. In order to ensure its normal operation efficiency, it is necessary to arrange the work reasonably and distribute it according to the different nature and duration of work. To ensure that each task can be completed in an efficient manner. Reasonable arrangement of working load can not only bring the mechanical efficiency into full play, improve the working efficiency, but also is a very good way to maintain the machinery itself. If the machine is in long-term overload operation, it will greatly increase the mechanical loss, resulting in unnecessary mechanical loss. Timely maintenance 8-hour Maintenance 1) Check oil and water. Discharge the waste oil from the bottom of the tank. Oil and water filling should not exceed the midline of the scale. Put clean oil at the bottom of the tank and stop. Complete. 2) Lubricants, arms, arms, buckets. Butter should be beaten in order to avoid forgetting, from left to right, or from bottom to top. Use two pieces of toilet paper, one is torn into two halves, hold the butter gun, the other is torn into four halves, wipe the butter gun to ensure that the butter gun is clean and shiny. The last quarter of the paper wraps the head of the butter gun. 50 Hours Maintenance 1) Oil-water separator. If it's dirty, let it go. 2) Check the hydraulic oil. Note: In the horizontal position, the arms are on the ground. The bucket must be digged up and dug to the bottom. 250 Hours Maintenance 1) Check the oil level of the rotating internal gear. 2) Check the oil level of the walking motor. 3) Monthly. Check the battery liquid of the battery. 500 Hours Maintenance Change the oil and the filter element of firewood. Butter is injected into the rotary gear. 1000 Hours Maintenance Replacement of hydraulic oil filter element, pilot filter element, anti-corrosion filter element. The walking motor replaces the gear oil. 2000 Hours Maintenance Replace hydraulic oil. |
