High pressure pipeline filter oil leakage problem analysis
High pressure pipeline filter oil leakage problem may be caused by a variety of factors, the following are some possible causes and corresponding solutions:
1. High pressure pipeline filter damage.
The filter element is seriously blocked by pollutants in the work and is not cleaned in time, increasing the pressure difference between the flow into and out of the filter element, so that the strength of the filter element is not enough, resulting in the deformation and destruction of the filter element. Regular inspection and replacement of the filter element is a key measure to prevent such problems.
2. Improper high pressure pipeline filter selection.
If the filter type and rated pressure do not match the working pressure of the system, it may lead to the filter element being broken down and destroyed. Ensuring the selection of the right type of filter and pressure class is critical to the stable operation of the system.
3. Improper pipe installation.
Improperly installed pipe joints. If the tightening torque exceeds the specified limit, the pipe horn may break, thread strain, or trip, resulting in oil leakage. During the installation, strictly follow the installation specifications to ensure the correctness and tightness of pipe connections.
4. Large vibration of the pipeline.
The pipeline may be damaged by excessive vibration during use, resulting in oil leakage. The effect of line vibration can be reduced by adding supports or using vibration damping materials.
5. Oil pollution.
oil pollution is one of the main causes of hydraulic system failure, regularly through the oil pollution analyzer to analyze and detect the cleanliness of the oil to ensure that the hydraulic components in the system have a long life and reduce the occurrence of failures.
6. Improper bending radius of high pressure pipeline filter.
When installing hard pipes and hoses, if the bending radius does not meet the requirements, it may cause the pipe wall to become thin or wrinkle, resulting in oil leakage under the action of oil pressure. Therefore, during the assembly process, the bending radius of the pipeline should be ensured to meet the specified standards.
7. High pressure impact of high pressure pipeline filter.
Under severe vibration or high pressure impact, if the strength of the pipeline is insufficient, it may produce transverse or longitudinal cracks at the bend and oil leakage. Selecting the appropriate pipe and strengthening the support of the pipe can effectively prevent this problem.
8. Accumulator failure.
In a hydraulic system equipped with a high pressure accumulator, if the accumulator fails, the oil backfilling may flush out the filter. Regular inspection of the working status of the accumulator and necessary maintenance are important measures to prevent such problems.
