Vacuum pump is usually composed of motor, impeller, sealing device and discharge port.
Functions and functions: automotive vacuum pump is mainly used Compatible With auxiliary braking system, providing vacuum power and enhancing braking effect.
Working principle: The negative pressure generated by the operation of the engine is absorbed by the vacuum pump to form a vacuum.
Associated with the brake system: the vacuum pump is connected to the vacuum booster of the brake system, and the force of the brake is enhanced by the negative pressure generated by the vacuum pump.
Diaphragm type vacuum pump: This type of vacuum pump uses contraction and expansion of the diaphragm to create a vacuum.
