Abstract
The utility model discloses an air inlet pipe of an intercooler used for a diesel engine. The utility model includes a pipe body made of metallic materials, and the pipe body is provided with two end portions which are connected with the pressure booster and the intercooler of the diesel engine. A rubber material layer is solidified on the external surface except two end portions of the pipe body, and the rubber material layer is provided with two turn hoops which outward protrude at intervals. Due to the fact that the rubber material layer is solidified on the external surface of the metallic pipe body, when the high pressure draught generated at the time of the pressure booster working flows through the air inlet pipe of the intercooler, and the vibration of the air inlet pipe of the intercooler is weakened, and the noise of air flowing is decayed by the rubber material layer, and the noise transmitted outside is considerably reduced. The periphery of the rubber material layer is provided with two turn hoops which outward protrude at intervals, which can further weaken the vibration of the air inlet pipe of the intercooler, and the total noise of the diesel engine is reduced. The utility model is provided with simple structure, low manufacturing cost, firm pipe head installation, convenient accomplishment, and the noise reducing effect of the diesel engine is obvious.
Description
Technical field
The utility model relates to a kind of diesel engine intercooler suction tude.
Background technique
For improving the Economy and the power character of diesel engine, reduce the diesel engine noxious gas emission, present most diesel engine all adopts refrigeration technique in the increase.Arranging because of component need, the pressurized machine intercooler suction tude before the diesel engine intake of giving vent to anger, the intercooler suction tude is the metal tube that adopts sheet iron to make mostly, in order to carrying the air after the supercharging, and the intercooler suction tude is rigidly fixed on a certain part of diesel engine.The defective of this structure is: air pressure height after the supercharging, flow velocity are fast, and the hydrodynamic noise of air can spread out of by the intercooler suction tude, has increased the noise of diesel engine; On the other hand, intercooler suction tude and diesel engine are rigidly connected, and the vibration of diesel engine can pass to the intercooler suction tude, make intercooler suction tude vibration aggravation and produce noise.The intercooler suction tude that also has all adopts the plastic materials manufacturing, but the suction tude of this structure is short working life, the cost of material height, and two tube heads are installed insecure.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly can effectively reduce the Diesel Engine Complete Machine noise, and the low intercooler suction tude of cost.
For solving the problems of the technologies described above, the utility model comprises the body of being made by metallic material, and body has two ends that are connected with diesel pressure booster and intercooler, and its structural feature is to remove on the outer surface of two ends at body to be solidified with the rubber material layer.
As to improvement of the present utility model, described rubber material layer has the twice circle hoop of evagination at interval.
The thickness of described rubber material layer is 3-5mm.
After adopting said structure, owing on the metal tube external surface, be solidified with the rubber material layer, when the high pressure that produces during pressurized machine work plays airflow passes intercooler suction tude, intercooler suction tude vibration weakening, the air flows noise is through the decay of rubber material layer, the noise that propagates into the outside reduces greatly, thereby reaches the purpose that reduces the Diesel Engine Complete Machine noise; And be provided with the twice circle hoop of evagination at interval in rubber material layer periphery, can further alleviate the vibration of intercooler suction tude, simultaneously, intercooler suction tude and diesel engine main body are tightened together by clamping band at this circle hoop position, becoming elasticity by being rigidly connected between original and diesel engine is connected, make vibration that diesel engine when work produce through the decay of circle hoop portion, further reduce the intercooler suction tude vibration and and diesel engine between the resonance that produces, the Diesel Engine Complete Machine noise is reduced.The utility model is simple in structure, low cost of manufacture, and tube head is installed firmly, is convenient to implement, be example with WD615 diesel engine comparative trial, adopt the intercooler suction tude of this structure, 0.1～0.2db (A) falls in complete machine maximum noise value, and it is obvious that diesel engine noise reduces effect.
Description of drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is a semi-section structural representation of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment
With reference to accompanying drawing, this use for diesel engine intercooler suction tude comprises the body of being made by metallic material 1, body 1 has two ends 4 that are connected with diesel pressure booster and intercooler, be solidified with certain thickness rubber material layer 2 except that on the outer surface of two ends 4 through sulfuration process at body 1, the thickness of this rubber material layer 2 is 3-5mm.Be provided with the twice circle hoop 3 of evagination at interval in rubber material layer 2 periphery simultaneously, the thickness at circle hoop 3 places is about 2 times of rubber material layer 2 thickness, circle hoop 3 is set, the one, be convenient to intercooler suction tude and diesel engine main body be tightened together by clamping band, the 2nd, the vibration that can further alleviate the intercooler suction tude.
Claims (3)
1, a kind of use for diesel engine intercooler suction tude, comprise the body of making by metallic material (1), body (1) has two ends (4) that are connected with diesel pressure booster and intercooler, it is characterized in that being solidified with rubber material layer (2) at body (1) except that on the outer surface of two ends (4).
