Automotive vacuum pump principle introduction

In the modern car manufacturing, will be specially added vacuum assisted braking system, namely: car vacuum pump. The system helps the driver to brake, making driving safer and effective to avoid traffic accidents. Then understand the working principle of car vacuum pump is very necessary today Xiaobian introduce you to the working principle of car vacuum pump. The composition of automotive vacuum pump Principle of automotive vacuum pump Automotive vacuum pump is mainly composed of pump body, rotor, blades and intake and exhaust ports and other components, the main types are the following: single vane vacuum pump, plunger vacuum pump and multi-vane vacuum pump, One single vane vacuum pump and multi-blade vacuum pump more used. The three main types of vacuum pumps are driven as follows: Single-vane vacuum pump type of drive is generally driven by the engine camshaft. Plunger vacuum pump drive in the form of general drive. Multi-blade vacuum pump drive in the form of belts, generators, gears and motors. Working Principle of Automotive Vacuum Pump For vacuum source of vacuum booster system, vehicles equipped with gasoline engine can generate high vacuum pressure in the intake manifold due to the ignition of the engine, which can provide sufficient vacuum source for the vacuum assisted braking system However, for a diesel engine driven vehicle, since the engine uses a Compression Ignition cycle (CI) so that the same level of vacuum pressure can not be provided at the intake manifold, a vacuum pump providing a vacuum source needs to be installed. In addition, Gasoline Direct Injection (GDI), designed to meet the high emission and environmental protection requirements, can not provide the same level of vacuum pressure at the intake manifold to meet the requirements of the vacuum brake booster system. Therefore, a vacuum pump Provide a vacuum source. The above is the working principle of the car vacuum pump for your reference learning, in addition, the need for regular maintenance, to ensure its efficient operation, to extend the service life.
