Introduce

The automatic transmission oil pump seal is a seal located inside the automatic transmission oil pump. As the core component of the automatic transmission, the oil pump’s main function is to pump hydraulic oil from the oil tank to various parts in the transmission to ensure the normal operation of the transmission. The seal plays a sealing role to prevent hydraulic oil from leaking and affecting the performance and life of the gearbox. This seal is an important component to ensure the normal operation of the gearbox. Sufficient attention and attention should be paid during vehicle maintenance and upkeep to ensure the normal use and driving safety of the vehicle.

Certification standard

Currently, both domestic and international standards are included in the automatic transmission oil pump seal standard certification process used by the worldwide automobile industry. The worldwide standards that are most prevalent among them are the SAE and ISO standards.

  • ISO international standards are formulated by the International Organization for Standardization and are usually consensus reached through international consultations. The main characteristics of its standards are that they are globally applicable and have high authority and credibility.
  • SAE international standards are formulated by the Society of Automotive Engineers and are aimed at various technical standards in the field of automotive engineering. These standards are not only developed specifically for the automotive industry, but also guide automotive parts manufacturers in standard quality control.
  • These standards—JB/T6303, JB/T5363, and JB/T6442, for example—were developed by the Chinese car industry and are often better suited to the sector’s diverse and unique requirements.
Advantage and function

The automatic transmission oil pump seal is a key rubber component that makes the automatic transmission oil pump work properly. Its main function is to prevent oil leakage while keeping the internal pressure of the transmission and the flow rate of oil from being affected. Therefore, its advantages and main functions can be summarized into the following three aspects.

  1. First, efficient sealing effect. The automatic transmission oil pump seal can prevent oil leakage. Through the precise structural design of the seal, the oil cannot leak out from outside the oil pump through any gap in the pump body, maintaining the stability of oil pressure and flow in the system.
  2. Second, maintain a steady oil flow. Maintaining a steady oil flow rate and direction is another crucial job of the oil pump seal, which enables the oil pump to continually provide the necessary amount of oil inside the gearbox. Oil may now enter the gearbox to cool, lubricate, and shield the stationary rotor.
  3. Third, improve the working efficiency of the entire automatic transmission system. The proper use of the automatic transmission oil pump seal can improve the efficiency of the entire transmission system. The high quality of oil pump seals will increase the safety and durability of the transmission, so using high quality oil pump seals has a positive effect.
Conclusion

The automatic transmission oil pump seal is a crucial rubber component that prevents hydraulic oil leakage and affects the performance and life of the gearbox. It is essential to preserving the oil flow rate and internal pressure of the transmission. The benefits of the seal include effective sealing, preserving a steady oil flow rate and direction, and raising the transmission system’s overall efficiency. Superior oil pump seals improve the transmission’s longevity and safety, which makes them crucial for car maintenance. For this reason, regular maintenance and upkeep are essential to the vehicle’s performance and safety.
