Hydraulic cylinder barrel repair: practical experience sharing.
1. Overview. The hydraulic cylinder barrel is an important part of the hydraulic system, and its performance directly affects the operation effect of the hydraulic system. However, due to the influence of long-term use and working environment, the hydraulic cylinder barrel may have problems such as wear, scratches, and deformation, which will affect the normal operation of the hydraulic cylinder barrel, so it is very necessary to repair the hydraulic cylinder barrel.
Second, the repair steps of the hydraulic cylinder barrel.
Surface treatment. First of all, the surface of the hydraulic cylinder barrel needs to be cleaned to remove impurities such as oil, dust, rust and so on. If the surface is severely worn or scratched, it needs to be coarsely ground and then finely ground until the surface is smooth and streak-free.
Resizing. If there is a deviation in the size of the hydraulic cylinder barrel, it needs to be adjusted. In general, adjustments can be made by machining or using specialized tools. If the dimensional deviation is large, the cylinder barrel may need to be replaced.
Sealed treatment. The sealing performance of the hydraulic cylinder barrel is an important factor to ensure the normal operation of the hydraulic system. If an oil leak is found, the seal needs to be inspected and replaced. When replacing the seal, it is necessary to pay attention to whether the size and specification of the seal meet the requirements.
Straightening and modification of hydraulic cylinder barrels.
For bent or deformed hydraulic cylinder barrels, straightening and reshaping are required. Straightening and dressing can be carried out on a specialized hydraulic straightening machine or dresser, or manually using specialized tools. It should be noted that over-machining should be avoided during the straightening and modification process to avoid greater damage to the cylinder barrel.
Quality inspection and testing.
After the repair is completed, the hydraulic cylinder barrel needs to be inspected and tested for quality to ensure that its performance meets the requirements. The test content includes size test, sealing performance test, pressure test, etc. During the test, it is necessary to operate according to the requirements to avoid excessive pressure or shock to the hydraulic cylinder barrel.
3. Summary. Hydraulic cylinder barrel repair is a highly technical work that requires certain professional knowledge and skills. When carrying out repairs, it is necessary to pay attention to safe operation and standardized operation to avoid causing greater damage to the hydraulic cylinder barrel. At the same time, for some problems that cannot be repaired, it is necessary to consider replacing the hydraulic cylinder barrel with a new one.
