The working principle of the automobile vacuum pump, first of all cars equipped with a gasoline engine, generally the engine uses an ignition type, so a relatively large vacuum pressure can be generated in the intake manifold. This can provide a sufficient vacuum source for the vacuum assisted braking system, but for a diesel engine-driven vehicle, because its engine uses a compression ignition type, it cannot provide the same level at the intake branch pipe. This requires the use of a vacuum pump that can provide a vacuum source. In addition, there are vehicles designed to meet certain environmental protection requirements for automobile emissions. It is also needed to provide sufficient vacuum sources to ensure that the car can normal operation.
The main output of the vacuum pump is the pressure generated by the power servo system, but when it fails to work normally, the hydraulic system can still be driven by manpower to assist. The power-assisted system of vacuum braking can also be called a vacuum servo system. The car braking system used in normal times mainly relies on hydraulic pressure as the transmission medium. Compared with the pneumatic braking system that can provide power, it needs a resistance system to brake the driver. To provide assistance.
The automobile vacuum pump mainly uses the vacuum generated by the engine when it is working, and then provides enough boost for the driver when stepping on the brake, so that the driver will be more brisk and easy to use when stepping on the brake, but once the vacuum pump is damaged, it will lack With a certain amount of boost, it will feel heavier when you step on the brakes, and the effect of the brakes will also be reduced, sometimes even failure, which means that the vacuum pump is damaged.
