Turbine impeller is a kind of rotating power machine which converts the energy of flowing working medium into mechanical work. It's an aero engine; Gas turbines and steam turbines; One of the main parts of automobile and Marine turbocharger.

Definition of turbine impeller

Chinese name: turbo

Turbine wheel and compressor wheel

Definition 1: impeller machinery that converts the energy of the mobile working medium into mechanical work. Applied discipline: aviation science and technology (first-level discipline); Propulsion technology and aeronautical power plant (secondary discipline)

Definition 2: impeller that outputs mechanical energy to the working machine and changes the moment of motion of the working fluid. Applied discipline: mechanical engineering (first-level discipline); Driving (second-level discipline); Hydraulic transmission

The working principle of

Take the working principle of gasoline engine as an example, every one kilogram of gasoline is provided to the cylinder, about 15 kilograms of air is inhaled by the cylinder to ensure the full combustion of gasoline. However, this 15 kilograms of air, its volume will be very large, relying on the vacuum degree of the cylinder in the engine intake process, it is not easy to completely absorb such a large volume of air. Therefore, it is particularly important to improve the ability of the engine to absorb gas, that is, to improve the aeration efficiency of the engine. There are two ways to increase the intake of an engine

Pressure technology, in principle, after the booster technology is the use of special compressor to gas

In advance before entering the cylinder compression, improve the gas density into the cylinder, reduce the gas

Volume. So, in unit volume, the mass of the gas is greatly increased

Meet the fuel combustion needs, so as to achieve the purpose of improving engine power. During pressurization

The compressor used is also called a supercharger. The second is the former intake technology, or use

The vacuum degree of the cylinder, from the inlet branch pipe to supplement the air into the cylinder. Whatever the technology,

Controlling the intake is the key.
