1. Application scenarios
Battery cooling system
The heat dissipation management of the battery pack in new energy vehicles is crucial, and many models use water cooling to maintain the battery at its optimal operating temperature. In this process, precise and reliable mechanical seals are required to prevent coolant leakage, and the device can also withstand small vibrations within a certain range, which helps ensure safe driving of the vehicle.
motor drive
The high-efficiency permanent magnet synchronous motor equipped on electric vehicles not only needs to have strong power output, but also needs to achieve low noise and low vibration. High quality and wear-resistant mechanical seals are widely used to ensure that there is no excessive energy loss during power transmission and to resist potential environmental issues such as moisture intrusion.
hydraulic system
Some hybrid models retain some of the mechanisms of traditional fuel vehicles, such as brakes or suspension systems, which generally involve hydraulic operation and require mechanical seals to ensure that hydraulic oil does not leak due to aging or rupture, and can also make the entire handling more flexible and smooth, improving the driving experience.

2. Type advantages and adaptability of mechanical seals
Single seal type
Single seal is the most common type of mechanical seal, with only one dynamic contact surface and necessary pressure provided by a spring. Its structure is relatively simple and the cost is low. In battery cooling systems, if the sealing requirements are not particularly high for some auxiliary pipelines or components, the single seal is more suitable and can achieve basic sealing needs at a lower cost.
Dual seal type
The dual seal design is used in environments with higher requirements, such as those involving high-temperature and high-pressure fluid transportation. Due to the presence of two contact points, it has stronger leak resistance. In the motor drive system, if the working environment pressure inside the motor is high and the sealing requirements are strict, the dual seal can better meet the needs and ensure the stable operation of the motor.
self-adjusting type
The self-adjusting type can automatically adjust its position to cope with vibration or deformation, suitable for use under high-speed operating conditions, and can further improve reliability. In the high-speed operation of electric motors in new energy vehicles and the inevitable vibration during vehicle driving, self-adjusting mechanical seals can play an advantage in battery cooling systems and motor drive systems, ensuring long-term stability of the seals.
Special material type
Special material types are specialized materials developed for extreme conditions such as corrosive media and high temperatures, such as ceramic composite materials, to enhance durability and performance. In battery cooling systems, if the coolant has a certain degree of corrosiveness or operates in high-temperature environments, special material mechanical seals can demonstrate their advantages, ensuring sealing effectiveness and service life.
3. The Importance of New Energy Vehicles
Ensure stable operation of the system
Mechanical seals can prevent leakage of coolant, hydraulic oil, etc., ensuring the normal operation of battery cooling systems, hydraulic systems, etc., maintaining the stable operation of key systems in new energy vehicles, and avoiding system failures and damage caused by liquid leakage.
Improve vehicle safety
Reliable mechanical seals can withstand vibrations within a certain range, ensuring safe driving of vehicles and preventing moisture from entering key components such as motors, reducing the risk of electrical failures and thus improving the overall safety of vehicles.
Improve performance and efficiency
In the motor drive system, a good mechanical seal can reduce energy loss, improve the working efficiency of the motor, and thereby enhance the power performance and endurance of new energy vehicles.
