The vacuum pump inside the car is generally an existence that assists the car. It is an indispensable thing. For those who do not know it well, for your car consideration, it is best to learn about this thing. What role does it play in the car, what is the working principle, and how to maintain it, only after you understand it can you know how to do it is the best for it.
It is understood that automotive vacuum pumps are mainly used in automotive braking systems, providing a vacuum source for vacuum boosters in automotive braking systems, reducing pedal resistance, and thus reducing braking distance. The braking system of the family car we usually use relies mainly on hydraulic pressure as the transmission medium. Compared with the pneumatic braking system that can provide power, it requires an assistant system to control the driving. The driver’s brakes provide assistance, and the vacuum brake booster system can also be called a vacuum servo system.
It first uses human-hydraulic braking, and then adds another source of braking capacity to help it. In this way, the two braking systems can be used together, that is, they can be used as braking together. In order to provide a system of energy, under normal circumstances, it mainly outputs the pressure generated by the power servo system, but when it cannot work normally, the hydraulic system can still be driven by manpower to help it. .
Working principle of vacuum pump:
First, a car equipped with a gasoline engine. Generally, the engine uses an ignition type, so a relatively large vacuum pressure can be generated when the intake branch pipe is used. This can provide a sufficient amount of vacuum source for the vacuum-assisted braking system, but for vehicles driven by diesel engines, because its engine uses compression ignition, it cannot be provided at the branch pipe of the intake air. At the same level of vacuum pressure, this requires the use of a vacuum pump that can provide a vacuum source. In addition, there are also engines designed by vehicles to meet certain automotive emission and environmental protection requirements. They also need to provide sufficient vacuum sources to ensure that The car can run normally.
Symptoms when the vacuum pump is damaged:
The vacuum pump makes use of the vacuum generated by the engine at work, and then provides sufficient assistance for the driver when the brake is applied, so that the driver will be more brisk when the brake is applied, but once the vacuum pump is damaged, it is lacking. A certain amount of assistance, so when you step on the brakes, it will feel relatively heavy, and the braking effect will be reduced, and sometimes it will even fail, which means that the vacuum pump is damaged. However, the vacuum pump cannot be repaired under normal circumstances, so after the damage occurs, it can only be replaced with a new one.
Borsehung vacuum pump is the core of auto parts, Full range for VAG car models. Products are suitable for Skoda, Volkswagen, Audi, Seat cars.
