All machines have trial operation. This is to detect whether there are problems in the device and whether it needs to be corrected. It needs to ensure the normal operation of the reducer without problems. It is also the guarantee for the efficient and long-term stable operation of the reducer in the future.
Due to the small operation interval of the components of the new device, and plus the device itself, the grease can’t become oil slick easily on the surface to prevent damage. In some serious cases, it may even lead to external scratches.
2. Wear fast
Because the contact area of the cooperation surface is small when the new reducer components are in the processing, installation and controlling , the torque is larger. During operation of the reducer, the concave and convex parts outside the components collide with each other, and the dropped metal debris, as abrasive, continues to be involved in the colliding, which accelerates the wear of the cooperative surface of the parts. Therefore, the wear rate is too fast during the trial operation. At this time, it may lead to damage to the parts if it’s under overloaded.
There will be leakage on the sealing surface and pipe joint of the reducer due to the looseness, vibration and rising temperature of the reducer; some casting defects are difficult to be detected, but due to the vibration and impact during the trial operation, such problems are manifested as oil leakage. Therefore, leakage may occur during the this period.
The newly delivered components may have some differences in shape and compatibility. At the beginning, due to the impact, vibration and other alternating loads, and the influence of heating & deformation as well as the rapid wear and other reasons, the original fastening parts become loose.
The above are what likely happen during the trial operation of the reducers. Trial operation is also kind of maintenance for the reducer, which is good and necessary for long-term operation.
