Modern construction, mining and agricultural operations are shifting toward high-intensity, round-the-clock operation, placing stringent requirements on the durability and stable performance of core machinery parts. Harsh working environments including heavy dust, mud and variable temperatures easily cause component wear and equipment failure, making high-quality sealing technology the key barrier to safeguarding continuous machine operation.
Persistent operational wear, frequent equipment downtime and insufficient high-end spare part supply have long plagued the global construction, mining and agricultural machinery sectors. As industrial equipment operates under harsher working conditions and higher load intensities worldwide, durable, precision-engineered sealing components have become a core determinant of machinery stability and service life.
1. Floating seal ring performance test and quality inspection
Verify the material selection and manufacturing process of the floating seal ring. It usually includes material composition analysis, metallographic analysis of heat treatment structure, metal surface Rockwell hardness test, determination of effective hardened layer depth after quenching, abrasion test, surface roughness test, coaxiality test, etc.
2. Rubber ring performance and quality test
The performance of the selected rubber ring is measured, so that it can be selected according to different application environments, and the appropriate compression deformation is designed to obtain the ideal resilience. It usually includes the test of rubber Shore hardness, the determination of rubber tensile properties, the determination of rubber resilience, the test of rubber liquid resistance, the hot air aging test of rubber, the determination of constant deformation and compression set of rubber at room temperature and high temperature, and the determination of rubber brittleness. Hard temperature test, etc.
3. Sealing load test
Use a tensile testing machine to test the specified combination of floating seal ring, rubber ring, and floating seal seat to determine the relationship between compression deformation and resilience. According to the requirements of the sealing surface of the floating seal ring, the relevant size of the floating oil seal is reasonably designed.
4. Static sealing test
The pair of clean floating seal rings are aligned and placed on the 0 level platform. Rubber pads or grease can be added to the bottom, and a counterweight pressure ring is added to the top. An appropriate amount of kerosene is poured in. It is required that the floating seal ring surface shall not leak and leak for 10 minutes. Oil seepage.
5. Dynamic sealing test
There are many types of dynamic seal testing machines, which require the ability to measure the sealing performance, working conditions (temperature rise, wear, etc.), service life, and the best value of the installation gap size of the floating oil seal in a standard and constant test environment. And according to the actual working conditions of the floating oil seal applied to the equipment, the test machine can be used to simulate the temperature of the environment, and it can be tested by adding sand, gravel, soil and other metal boxes.
