Chongqing blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base (and oil tank), and oil dripping nozzle. The blower runs eccentrically on the rotor offset in the cylinder, and the volume change between the blades in the rotor groove sucks the air in, compresses, and expits it. In operation, the pressure difference of the blower is used to automatically send lubrication to the drip nozzle, which is dripped into the cylinder to reduce friction and noise, and at the same time can keep the gas in the cylinder from backflowing, this kind of blower is also called a sliding vane blower.

The conveying medium of the blower is mainly clean air, clean gas, sulfur dioxide and other inert gases. It can also produce and transport other flammable, explosive, corrosive, toxic and special gases on demand.

A device that transmits energy to a continuously flowing fluid or pushes the blades to rotate by the dynamic action of rotating the blades on the impeller or by the energy transmitted by the fluid is called impeller machinery. In impeller machinery, rotating blades do positive or negative work on the fluid, making the pressure of the fluid rise or fall. Impeller machinery is divided into two categories: one is the working machine, from which the fluid absorbs power to increase the pressure head or water head, such as vane pumps and ventilators; The other type is prime mover, where fluids expand, reduce pressure, or head to produce power, such as steam turbines and water turbines. People call the prime mover a turbine, and the working machine a vane fluid machine.

According to the different working principles of the fan, it can be divided into two categories: vane type and volumetric type, of which the vane type can be divided into axial flow type, centrifugal type and mixed-flow type. According to the pressure generated by the fan, it can be divided into blowers, compressors and ventilators. China's current machinery industry standard JB/T2977-92 stipulates that the fan refers to the fan with an outlet pressure (gauge pressure) less than 0.015MPa under the condition of standard air inlet, a blower with an outlet pressure (gauge pressure) between 0.015MPa and 0.2MPa, and a compressor with an outlet pressure (gauge pressure) greater than 0.2MPa.

The main components of the Chongqing blower are: volute, collector and impeller.
