Abstract

The utility model discloses a turbo charger compressor of noise reduction contains intake duct, working wheel (being impeller), diffuser and compressor casing. The compressor is provided with a noise reduction ring, and noise generated by the compressor can be effectively reduced. The noise-reduced turbocharger compressor increases the engine intake air amount by compressing air. The engine uses the inertia impulse force of the waste gas discharged by the engine to push the turbine in the turbine, the turbine drives the coaxial impeller, and the impeller pressurizes the air sent by the air filter pipeline and then forcibly presses the air into the engine cylinder. When the rotating speed of the engine is increased, the exhaust speed of the exhaust gas and the rotating speed of the turbine are also increased synchronously, and more air sent by the air filter is compressed by the impeller to enter the cylinder.

Description

Turbocharger compressor of noise reduction

Technical Field

The utility model relates to a turbo charger technical field, an efficient turbo charger compressor reduces noise specifically says so.

Background

The turbocharger is an air compressor, and pushes a turbine in a turbine chamber by using the inertia impulsive force of waste gas with energy discharged by an engine, the turbine drives a coaxial impeller, and the impeller boosts air sent by an air filter pipeline and then forcibly presses the air into an air cylinder; the pressure and density of the entering air are increased, so that the fuel can be combusted more fully, the output power is improved, and the effects of reducing fuel consumption, saving energy and reducing emission are achieved.

However, the existing turbocharger still has many defects, and the problems of high noise, unstable work, lag and low efficiency of the compressor still need to be improved.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the above-mentioned not enough and the turbocharger compressor with noise reduction ring that provides, noise reduction ring is in the import department of compressor, noise that can effectual reduction compressor during operation produce, and noise reduction effect is obvious.

The technical scheme of the utility model is that: a noise reduction turbocharger compressor is provided, a noise reduction ring is arranged at the inlet of the compressor, and an inclined slit is arranged in the axial direction of a working impeller blade of the compressor to assist in guiding the flow of air flow; the turbocharger increases the air intake of the engine by compressing air. The engine uses the inertia impulse force of the waste gas discharged by the engine to push the turbine in the turbine, the turbine drives the coaxial impeller to rotate, and the impeller pressurizes the air sent by the air filter pipeline and then forcibly presses the air into the engine cylinder.

Preferably, a convergent air inlet is provided at the air inlet such that as the impeller rotates, a certain negative pressure is created at the forward end thereof to draw air into the impeller, while the convergent passage also minimises air flow losses.

Preferably, the impeller is formed by uniformly arranging and combining a series of blades at the shaft end, air is compressed, the blades of the impeller rotate to drive the air to rotate, and the air compression is completed with the help of centrifugal force, so that the air pressure is increased.

Preferably, after the compression process of the working wheel, the high-energy air flowing out of the working wheel has a certain amount of kinetic energy, and the part of kinetic energy contained in the compressed air is converted into pressure potential energy through the diffuser, so that the static pressure of the air flowing into the internal combustion engine is increased.

Compared with the prior art, the utility model discloses following benefit has:

(1) the utility model discloses noise reduction ring is equipped with in import department, noise that can effectual reduction compressor produced.

(2) The utility model discloses there is the slotting of a slope in the direction of compressor working impeller blade axis, comes the flow of supplementary guide air current, can guarantee the normal supply of air.

(3) The wind guide wheel and the working impeller of the utility model are integrated, which can effectively reduce the processing error and the dynamic balance weight; the valve is suitable for a high-pressure ratio compressor and has structural advantages; the overall milling impeller blade has higher surface quality, the efficiency of the compressor is improved, and the pneumatic noise of the supercharger is reduced.
