The core competitiveness of the TB type oil seal lies in its unique double-lip structure. This design not only enhances the sealing performance of the oil seal, but also significantly improves its ability to adapt to complex working conditions.
The main lip is the first sealing barrier of TB type oil seal. It adopts a precise geometric design to closely fit the shaft surface and form an effective sealing gap. This design enables the oil seal to reduce lubricant leakage during high-speed operation and ensure stable circulation of oil in the system. The material selection of the main lip has also been strictly screened to ensure that it has good wear resistance, high temperature resistance and elasticity, so that it can maintain stable sealing performance under various working conditions.
The secondary lip is the second line of defense for the TB-type oil seal. Its main function is to prevent dirt, dust and other contaminants from entering the system. The design of the auxiliary lip enables it to tightly scrape off impurities on the shaft surface and block them outside the oil seal. This feature not only keeps the inside of the machine clean, but also extends the service life of oil seals and related components. More importantly, the design of the auxiliary lip also takes into account the needs of different working conditions, such as material stability in high-temperature environments, structural strength in high-pressure environments, etc., to ensure that cleaning and maintenance capabilities can be maintained under various conditions. .
Can the double lip design of TB type oil seal really meet the challenges of all working conditions? The following is an analysis of its performance under high temperature, high pressure and high-speed operating environments.
In high temperature environments, the sealing materials and structural stability of oil seals face severe tests. TB type oil seal is made of high temperature resistant materials, such as fluorine rubber, silicone rubber, etc. These materials can maintain stable physical properties and chemical stability at high temperatures. At the same time, the double-lip design allows the oil seal to maintain a tight sealing gap under high temperatures, reducing lubricant leakage. In addition, the scraping function of the auxiliary lip is also effective in high temperature environments and can prevent the accumulation of impurities caused by thermal expansion and contraction.
In a high-pressure environment, the oil seal needs to withstand greater pressure and friction. The double lip design of the TB type oil seal enhances its structural strength, allowing it to withstand higher pressures without deformation or damage. At the same time, the tight fit of the main lip and the scraping function of the auxiliary lip are equally effective in high-pressure environments, ensuring the sealing performance and cleaning and maintenance capabilities of the oil seal. TB type oil seal has also undergone special processing, such as vulcanization, hardening, etc., to improve its pressure resistance and wear resistance.
In a high-speed operating environment, the oil seal needs to withstand huge centrifugal force and friction. The double-lip design of the TB-type oil seal enables it to closely fit the shaft surface, reducing the risk of lubricant leakage and impurity intrusion. At the same time, the material selection of the main lip also takes into account the wear resistance and elasticity requirements during high-speed operation. In addition, the TB type oil seal has also undergone dynamic balance testing to ensure that it can maintain stability and sealing performance during high-speed operation.
In order to verify the performance of TB type oil seal in practical applications, we conducted a number of field tests and case analyses. The following are some typical application scenarios and test results.
In engines, oil seals need to withstand multiple tests of high temperature, high pressure and high-speed operation. We selected an engine equipped with a TB-type oil seal for testing. The results showed that after thousands of hours of continuous operation, the sealing performance and cleaning and maintenance capabilities of the oil seal remained good. Especially in high-temperature environments, the leakage of the oil seal is significantly reduced, ensuring the lubrication effect and operating efficiency of the engine.
The oil seal in the transmission needs to withstand frequent shifting shocks and the friction of high-speed operation. We selected a transmission equipped with a TB-type oil seal for testing. The results showed that the sealing performance and cleaning and maintenance capabilities of the oil seal were stable and reliable during long periods of high-speed operation and shifting. Especially in high-pressure environments, the structural strength of the oil seal has been fully verified, with no deformation or damage.
The oil seal in the wheel bearing needs to withstand large centrifugal force and vibration impact force. We selected a wheel bearing equipped with a TB-type oil seal for testing. The results showed that the sealing performance and cleaning and maintenance capabilities of the oil seal remain stable and reliable under high-speed driving and harsh road conditions. Especially in wet and muddy road conditions, oil seals can effectively prevent moisture and dirt from intruding into the system, ensuring the normal operation and safety of wheel bearings.
