Abstract
The utility model discloses a silencing mechanism for a turbocharger air outlet, which relates to the field of turbochargers.
Description
Technical Field
The utility model relates to the field of turbochargers, in particular to a silencing mechanism for an air outlet of a turbocharger.
Background
Turbochargers are actually air compressors that increase the amount of intake air by compressing the air. The turbine drives a coaxial impeller by utilizing the inertial impulse of exhaust gas discharged by the engine, and the impeller presses and sends air sent by an air filter pipeline to be pressurized into a cylinder. When the rotation speed of the engine is increased, the exhaust gas discharge speed and the rotation speed of the turbine are synchronously increased, more air is compressed by the impeller to enter the cylinder, more fuel can be combusted by increasing the pressure and the density of the air, and the output power of the engine can be increased by correspondingly increasing the fuel quantity and adjusting the rotation speed of the engine.
Bulletin number: CN213016537U discloses a silencing mechanism for an air outlet of an automobile turbocharger, which comprises a cylinder, wherein an air inlet pipe is concentrically and integrally connected to the outer side wall of the bottom of the cylinder, and a first central hole is formed in the bottom of the cylinder corresponding to the air inlet pipe, so that the air inlet pipe is communicated with the inner cavity of the cylinder, and the diameter of the first central hole is the same as the inner diameter of the air inlet pipe. And a silencing pipe is concentrically arranged in the cylinder body, the silencing pipe is made of silencing cotton, one end of the silencing pipe abuts against the bottom of the cylinder body, and the inner diameter of the silencing pipe is equal to that of the first central hole.
The noise of the air outlet of the turbocharger is increased during air outlet, so that the noise needs to be reduced through the silencing structure, the disappearing structure and the turbocharger pipeline in the document are of an integrated structure, and although the soundproof cotton can be replaced, if other parts are damaged, the structure cannot be replaced, and the practicability of the silencing structure is greatly reduced.
Disclosure of Invention
The utility model mainly aims to provide the silencing mechanism for the air outlet of the turbocharger, which can be directly replaced when the disappearing structure fails, so that the practicability of the silencing structure is greatly improved, and the problems in the background technology can be effectively solved.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a turbo charger is noise reduction mechanism for gas outlet, includes noise reduction main pipe and outlet duct, the lateral wall welding of outlet duct has the circular recess seat that internal surface and rubber bond, the outlet duct lateral wall is located circular recess seat the place ahead and noise reduction main pipe's inside wall threaded connection.
Further, the two sides of the silencing main pipe are communicated with each other and connected with a shunt pipe.
Further, the outer side wall of the shunt tube is detachably connected with a dustproof screen through a screw.
Furthermore, the outer side walls of the silencing main pipe and the shunt pipe are adhered with silencing cotton.
Compared with the prior art, the utility model has the following beneficial effects: the silencer main pipe on the silencer structure is propped against the air outlet pipe on the turbocharger, the silencer main pipe is rotated clockwise to install the silencer main pipe on the air inlet pipe, after installation, the tail end of the silencer main pipe is inserted into the circular groove seat, rubber in the circular groove seat is tightly stuck to the silencer main pipe by means of good elastic performance, the tightness of connection is good, the silencer main pipe is rotated anticlockwise to detach the silencer main pipe from the air outlet pipe during detachment, the silencer main pipe is convenient to detach and replace when faults occur, the practicability of the silencer main pipe is greatly improved, after installation is completed, the exhaust air flow of the air outlet pipe on the turbocharger enters the silencer main pipe, the air channels of the silencer main pipe are split by the split pipes on two sides of the silencer main pipe, the air channels of the silencer main pipe are changed and split into two branches, acting force can be well reduced, the contact surface between the air flow and silencer cotton can be greatly increased, and noise can be well reduced.
