After the turbine reducer leaves the factory, it is generally stipulated that there is a running-in period of about 200 hours, and the oil must be changed after the time. This is stipulated by the technical characteristics of the initial stage of the use of the reduction equipment.The running-in period is an important link to ensure normal operation, reduce the failure rate, and extend its service life.However, some users currently ignore the special technical requirements of the new machine during the run-in period due to lack of common sense or because of insufficient allowable torque, or want to obtain profit as soon as possible, and use the small machine. This is very undesirable. What should be paid attention to during this period?
1. Fast wear speed
Due to the influence of factors such as the processing, assembly and debugging of parts of the new turbine reducer, the contact area of the mating surface is small, and the allowable torque is large.During operation, the concave and convex parts of the part surface are interfitted and rubbed against each other, and the metal scraps that are ground down are used as abrasives to continue to participate in the friction, which accelerates the wear of the mating surface of the part.Therefore, during the running-in period, it is easy to cause the wear of the parts, and the wear rate is too fast.At this time, if the load is overloaded, it may cause damage to the parts and cause early failure.
2. Poor lubrication
Due to the small fit clearance of newly assembled parts, and due to assembly and other reasons, lubricating oil (grease) is not easy to form a uniform oil film on the friction surface to prevent wear.Thereby reducing the lubrication efficiency, causing the early abnormal wear of the machine parts.In severe cases, it will cause scratches or seizures on the friction surface of the precision fit, leading to failures.
3. Loose
Newly processed and assembled parts and components have deviations in geometric shape and matching dimensions. In the early stage of use, due to the impact of alternating loads such as shock and vibration, as well as the influence of factors such as heat and deformation, and excessive wear and other reasons, they are easy to cause The originally fastened parts are loose.
4. Leakage occurs
Due to the loosening of parts, vibration and heat of the turbine reducer, there will be leakage at the sealing surface and pipe joints; some casting defects are difficult to find during assembly and debugging, but due to vibration and impact during operation , This kind of defect is exposed, manifested as oil leakage (seepage).Therefore, leakage occurs occasionally during the running-in period.
5. Many operating errors
Due to the insufficient understanding of the structure and performance of the turbine reducer (especially for new operators), it is easy to cause malfunctions due to operating errors, and even cause mechanical accidents and safety accidents.
