Description

Expansion tank

Technical Field

The utility model relates to an automobile manufacturing technical field, concretely relates to expansion tank.

Background

The automobile supercharger is a vane machine rotating at high speed, and the noise generated during operation is not only high in sound level but also high in frequency, and is a main noise source of a supercharged diesel engine set. And the noise of the supercharger is divided into turbine noise and compressor noise. The noise source of turbocharging belongs to high frequency broadband noise, and the aerodynamic noise that the turbine produced gets into exhaust system together with the exhaust noise of engine, and these noises if do not pass outside the car directly, produce great noise pollution to the outside.

SUMMERY OF THE UTILITY MODEL

To the above problem, the utility model aims at providing an expansion tank.

In order to realize the technical purpose, the utility model discloses a scheme is:

preferably, the expansion tank comprises an expansion tank shell, and is characterized in that: the expansion tank shell both sides be provided with external screw thread, expansion tank shell inner chamber be provided with the amortization baffle, amortization baffle both sides be provided with the muffler, expansion tank shell surface be provided with the fixed bolster, the fixed bolster surface be provided with two sets of fixed through-hole.

Preferably, one side of the silencing partition board is provided with a through hole.

Preferably, a plurality of small holes are uniformly distributed on the outer surface of the silencing partition plate in a ring shape.

Preferably, the center of the external thread is provided with a through round hole, and the through round hole is communicated with the silencer.

The beneficial effects of the utility model, simple structure, convenient operation, the exit of muffler adopts coaxial setting, and the resistance loss of muffler is extremely low, and the through-hole of amortization baffle is perpendicular with the direction of external screw thread air inlet, gas outlet, has also played good amortization function in filtered air, can effective noise reduction.
