The running-in period of Shanyu loader was mentioned some time ago. Then I would like to share with you some things that our Shanyu loader needs to pay attention to when running-in.
Use and maintenance
1. As Shanyu construction machinery is a special vehicle, operators should receive formal training and guidance, have a full understanding of the structure and performance of Shanyu machinery, and gain some experience in operation and maintenance before operating the machine. The Safety Operation and maintenance Manual of hydraulic Loader provided by Shanyu manufacturer is a necessary information for operators to operate the equipment. Before operating the machine, you must read the Safety Operation and maintenance Manual of hydraulic Loader and carry out operation and maintenance as required.
two。 Pay attention to the workload during the running-in period. Half of the workload during the running-in period should not exceed the rated workload.60%And arrange a suitable workload to prevent the occurrence of overheating caused by the continuous operation of the machine for a long time.
3. Pay attention to often observe the instructions of each instrument, stop in time to eliminate any abnormalities, and stop the operation before the cause is found and the fault is not eliminated.
4. Always check the level and quality of lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water), and check the tightness of the whole machine. During the inspection, it is found that there is too much oil and water, and the reason should be analyzed. At the same time, the lubrication of each lubrication point should be strengthened, and it is suggested that during the running-in period, each shift should add grease to the lubrication point (except for special requirements).
5. Keep the machine clean, adjust and fasten the loose parts in time to prevent the loose parts from aggravating the wear and tear or causing the parts to be lost.
6. At the end of the running-in period, compulsory maintenance of the machine should be carried out, inspection and adjustment should be done, and attention should be paid to the replacement of oil.
In a word, the requirements for the use and maintenance of Shanyu loader during the running-in period can be summarized as follows: strengthening training, reducing load, paying attention to inspection and strengthening lubrication. As long as we pay attention to and implement the maintenance and maintenance of the Shanyu loader during the running-in period as required, it will reduce the occurrence of early failures, prolong the service life, improve the operation efficiency, and make the machine bring more benefits for you.
The characteristics of the running-in period
1. Wear speed is fast
Due to the influence of the processing, assembly and adjustment of the parts of the new machine, the friction surface is rough, the contact area of the mating surface is small, and the pressure-bearing condition of the surface is uneven. During the operation of the machine, the concave and convex parts of the surface of the parts rub against each other, and the metal fragments continue to participate in the friction as abrasives, which speeds up the wear of the matching surface of the parts. Therefore, the content of the running-in period is easy to cause parts (especially the mating surface) wear, and the wear speed is fast. At this time, if the overload operation, it may lead to damage to the parts and components, resulting in early failure.
two。 Poor lubrication
As the fit gap of the newly assembled parts is small, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fit gap, lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. As a result, the lubrication efficiency is reduced and the early abnormal wear of the parts is caused. In serious cases, it will cause scratches or bites on the friction surface of precision fit, which will lead to failure.
3. Loosening occurs
There are deviations in geometric shape and fit size of newly machined and assembled parts. At the initial stage of use, due to the influence of alternating loads such as impact and vibration, as well as factors such as heat and deformation, as well as excessive wear, it is easy to loosen the original fastened parts.
4. Leakage occurs
Due to the influence of the loosening and vibration of the machine parts and the heat on the machine, there will be leakage on the sealing surface and pipe joint of the machine, and some defects such as casting and processing are difficult to be found during assembly and debugging, but because of the vibration and impact in the process of operation, this defect is exposed, manifested as oil leakage (water), so it is easy to leak during the running-in period.
5. There are many operational errors.
Due to the lack of understanding of the structure and performance of the machine (especially the new operator), it is easy to cause failures and even mechanical accidents due to operation errors.
