Abstract
The utility model discloses an engine whirlpool final vacuum return bend, connect the round flange, support lug, first return bend, bellows, second return bend, booster connection round flange, its characterized in that including the silencer: bellows inside pipe wall and outside of tubes wall all are the corrugate. Round flange, first return bend, bellows, second return bend, booster connection round flange welded connection is in proper order connected to the silencer, the utility model has the advantages of with low costs, service problem is rateed low, vibration resistance and absorption and is warp by force.
Description
Technical field
This utility model relates to an electromotor whirlpool final vacuum bend pipe.
Background technology
The installation of supercharging tractor silencer at present is connected with electromotor by whirlpool final vacuum bend pipe, and when electromotor runs, acoustic filter has vibration, and can be delivered to engine supercharger.If rigid connection, then there will be the fault damaging supercharger because of the vibration of acoustic filter.Therefore, this area need a kind of to be convenient to mount and dismount, reliable in quality, vibration resistance and the strong whirlpool final vacuum bend pipe of absorption deformation.
Summary of the invention
This utility model causes turbocharger impairment problem to meet the above-mentioned vibration preventing acoustic filter, it is provided that a kind of be convenient to mount and dismount, reliable in quality, vibration resistance and the strong whirlpool final vacuum bend pipe of absorption deformation.
For reaching above-mentioned purpose, what this utility model provided technical scheme is:
A kind of electromotor whirlpool final vacuum bend pipe, connects round flange 1 including acoustic filter, supports lug the 2, first bend pipe 3, corrugated tube the 4, second bend pipe 5, supercharger connection round flange 6, and described corrugated tube 4 inside pipe wall and pipe outer wall thereof are the most corrugated.
Further, described corrugated tube 4 uses the material also under 500 degrees Celsius of high temperature above with toughness.
Further, the inside and outside ripple of described corrugated tube 4 all uses " U " type annular corrugated.
Further, described support lug 2 is integrated on the first bend pipe 3, is used for assisting support whirlpool final vacuum bend pipe；
Further, described acoustic filter connection round flange the 1, first bend pipe 3, corrugated tube the 4, second bend pipe 5, supercharger connect round flange 6 and are welded to connect successively；
Further, described first bend pipe 3 is orthogonal with the longitudinal section of the second bend pipe 5.
Compared with prior art, this utility model has the advantages that
1, vibration resistance and absorption deformability are strong, can compensate the tolerance stack between part and provide temperature compensation space, and the vibration that can effectively cut down acoustic filter is delivered to supercharger.
2, directly it is welded to connect between each parts, not only reduces cost but also reduce the fault rate of entirety.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model a kind of electromotor whirlpool final vacuum bend pipe.
Fig. 2 is the right view of this utility model a kind of electromotor whirlpool final vacuum bend pipe.
Fig. 3 is the top view of this utility model a kind of electromotor whirlpool final vacuum bend pipe.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
A kind of electromotor whirlpool final vacuum bend pipe, connects round flange 1 including acoustic filter, supports lug the 2, first bend pipe 3, corrugated tube the 4, second bend pipe 5, supercharger connection round flange 6, and described corrugated tube 4 inside pipe wall and pipe outer wall thereof are the most corrugated.The material that described corrugated tube 4 uses is 0Cr18Ni9, and Bellows Length about 9cm, wall thickness is 0.8mm, reaches 120HV～140HV (Vickers hardness).The inside and outside ripple of described corrugated tube 4 all uses " U " type annular corrugated.Described support lug 2 is integrated on the first bend pipe 3, is used for assisting support whirlpool final vacuum bend pipe；Described acoustic filter connection round flange the 1, first bend pipe 3, corrugated tube the 4, second bend pipe 5, supercharger connect round flange 6 and are welded to connect successively；Described first bend pipe 3 is orthogonal with the longitudinal section of the second bend pipe 5.
The specific embodiment of the utility model that is only disclosed above, but, this utility model is not limited to this, and the changes that any person skilled in the art can think of all should fall into protection domain of the present utility model.
