The Working Principle of Air Compressor for the Car

Air compressor for the car is a device used to compress gas. Air compressor for the car is similar to the pump construction. Most air compressor for the car are reciprocating pistons, rotating blades or rotating screws. Centrifugal compressors are very large applications.

Air compressor for the car is also called an air pump. Its working principle is to pump natural air into the air reservoir or air tank of the automobile chassis. The motor drives the compressor directly to make the crankshaft generate rotational motion and drive the connecting rod to generate the piston. Reciprocating motion causes a change in cylinder volume. Due to the change of the pressure in the cylinder, the air is passed through the air filter (muffler) through the intake valve into the cylinder. During the compression stroke, due to the reduction of the cylinder volume, the compressed air passes through the exhaust valve and passes through the exhaust pipe. The valve (check valve) enters the gas tank. When the discharge pressure reaches the rated pressure of 0.7MPa, it is automatically stopped by the pressure switch. When the pressure of the gas tank drops to 0.5--0.6MPa, the pressure switch is automatically connected and started.

Before starting the Air compressor for the car, first start the oil pump control system. After the start of the oil pump control system, ensure that the lubrication parts of the air compressor are well lubricated. At the same time, the oil pump control air compressor system can adjust the internal oil pressure through the built-in temperature control valve and Oil temperature to meet system needs.

Most of the medium- and heavy-duty vehicles produced in China are based on air compressor for the car. The main functions of air compressor for the car include: clutch assistance, brake assist, and air suspension systems such as seats and tire inflation. Large cars use pneumatic boost to increase the braking force. The car is equipped with an air compressor. In order to dissipate heat and lubricate the engine oil pump, there are inlet and outlet pipe connections.
