Do you know the Daily Maintenance of the Loader?

As a Mini Wheel Loader Manufacturer, share with you. After the loader leaves the factory, it is generally stipulated that there is a break-in period of about 60 hours, which is based on the technical characteristics of the loader in the initial stage of use. The running-in period is an important link to ensure the normal operation of the loader, reduce the failure rate, and extend its service life. Some users ignore the special technical requirements of the new machine's running-in period due to lack of common knowledge about the use of the loader, or because of the tight construction period, or want to obtain profits as soon as possible. Some users even believe that the manufacturer has a warranty period anyway, and the manufacturer is responsible for maintenance if the machine is broken. Therefore, the machine is overloaded for a long time during the running-in period, resulting in frequent early failures of the machine. Shortened the service life of the machine, and also affected the progress of the project because of the damage to the machine. Therefore, the application and maintenance of the break-in period of the loader should be given full attention.

Run-in period

Fast wear speed Due to the influence of factors such as processing, assembly and adjustment of new machine parts, the friction surface is rough, the contact area of the mating surface is small, and the surface pressure is uneven. During the operation of the machine, the concave and convex parts of the surface of the parts are fitted and rubbed with each other. The metal debris that has fallen down continues to participate in the friction as an abrasive, which further accelerates the wear of the matching surface of the parts. Therefore, it is easy to cause wear of parts during the running-in period, and the wear speed is fast. At this time, if overloaded, it may cause damage to components and lead to early failure.

Poor lubrication Due to the small fitting gap of newly assembled parts, and due to assembly and other reasons, it is difficult to ensure the uniformity of the fitting gap. Lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear. Thereby reducing the lubricating efficiency, causing early abnormal wear of the machine parts. In severe cases, the friction surface of the precision fit may be scratched or bitten, resulting in failure.

The loosely processed and newly assembled parts have deviations in geometry and fitting dimensions. At the initial stage of use, due to the impact of alternating loads such as shock and vibration, as well as the effects of heat and deformation, plus excessive wear and other reasons, it is easy to Make the original fastened parts loose.

Leakage occurs Due to the looseness of the machine parts, vibration and heat of the machine, the sealing surface of the machine and the pipe joints will leak out. Some casting and processing defects are difficult to find during assembly and debugging, but due to the operation process This kind of defect is exposed as a result of vibration and shock. Therefore, it is prone to leakage during the running-in period.
