How to perform stress tests to detect performance of R107D160M4-11KW reducer seal

Stress testing is an important method to detect the performance of R107D160M4-11KW reducer seals. The following are the specific testing steps and related points:

1. Preparation before testing

• Select a test medium : gases such as compressed air, nitrogen, etc. can be used as the test medium, or liquids such as water or oil can be used as the test medium. Gas testing is easy to operate, while liquid testing can better simulate the media situation in actual work.

• Prepare test equipment : prepare pressure sources, such as air compressors or hydraulic pumps; pressure sensors, used to monitor pressure changes; and related valves, pipes and other connecting components to ensure that all equipment is in good working condition.

• Check the reducer : Make sure the reducer has been completely shut down and cooled, check the appearance of the reducer, ensure there is no obvious signs of damage or leakage, close all inlet and outlet valves of the reducer, and ensure that the medium does not leak to the external environment during the test.

2. Test connection

• Connect the pressure source through the pipe to the air inlet or liquid inlet of the reducer to ensure that the connection is tight and there is no leakage. Install pressure sensors on the pipes to accurately monitor pressure changes. If more precise detection of leakage locations is required, apply dye penetrant to the sealed area of ​​the reducer or use equipment such as a helium mass spectrometer.

3. Apply pressure

• Slowly turn on the pressure source, gradually inject gas or liquid into the reducer, and increase the pressure to the specified value according to the design pressure requirements of the reducer seal. For example, if the rated working pressure of the seal is 1MPa, the test pressure can be set to 1.5MPa (static pressure withstand test) to verify the sealing performance of the seal at higher than the working pressure. After the set pressure is reached, close the pressure source valve and start holding pressure.

4. Pressure monitoring and leak inspection

• Pressure sensors are used to continuously monitor pressure changes and record the pressure value during pressure holding. If the pressure can remain stable within a specified time (such as 30 minutes) and the pressure drop is less than a certain proportion (such as 5%), it means that the sealing performance of the seal is good. At the same time, carefully observe whether there are any leakage signs of the various sealing parts of the reducer, such as the box joint surface, shaft extension, oil marking hole, etc. If a dye penetrant is used, it can be observed whether the dye penetrates to the other side of the seal; if a helium mass spectrometer is used, it can be detected whether there is helium leakage.

5. Test results evaluation

• The performance of the seal is evaluated based on pressure monitoring data and leak inspection. If the pressure drops significantly or there is a leak point, it means there is a problem with the seal and needs further inspection and repair or replacement. If the pressure remains stable and there is no leakage, the seal passes the pressure test and its performance meets the requirements.

6. Post-test processing

• After the test is completed, slowly release the pressure in the reducer and remove the test connection pipes and equipment. Clean the reducer and remove the applied dye penetrant and other substances. If there is any problem with the seal during the test, repair or replace it in time and re-pressure test is carried out until the seal performance meets the requirements.
