Abstract
The utility model discloses an air inlet pipe of a charge air cooler for diesel engines, which comprises a pipe body made of rubber. The inner parts of both ends of the pipe body is connected with a pipe head which is connected with a diesel engine supercharger and a pipe head which is connected with a charge air cooler. The pipe body is provided with two distant convex hoops. The pipe heads of the utility model have firm installation. When high voltage airflow produced during the operation of the supercharger flows into the air inlet pipe of the charge air cooler, noise which is sent to the outside is greatly reduced. The pipe body is provided with the two distant convex hoops, so the vibration of the air inlet pipe of the charge air cooler and the resonance generated between the air inlet pipe of the charge air cooler and a diesel engine can be further reduced, and the noise of the entire diesel engine is reduced. The utility model has simple structure, low manufacturing cost, convenient operation, and obvious noise reducing effect on the diesel engine.
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 intercooler suction tude that is connected firmly.
For solving the problems of the technologies described above, the utility model comprises the body of being made by rubber material, and its structural feature is to be connected to tube head that is connected with diesel pressure booster and the tube head that is connected with intercooler in two ends of body.
As to improvement of the present utility model, has the twice circle hoop of evagination at interval on the described body.
The wall thickness of described body is 3-5mm.
After adopting said structure, because body adopts rubber material to make, and in two ends of body, be connected to tube head that is connected with diesel pressure booster and the tube head that is connected with intercooler, tube head is installed firmly, 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 body, the noise that propagates into the outside reduces greatly, thereby reaches the purpose that reduces the Diesel Engine Complete Machine noise; And body is provided with the twice circle hoop of evagination at interval, 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, and low cost of manufacture is convenient to implement, and is example with WD615 diesel engine comparative trial, adopts the intercooler suction tude of this structure, and 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 rubber material 2, the wall thickness of body 2 is 3-5mm, in two ends of body 2, be connected to tube head 1 that is connected with diesel pressure booster and the tube head 4 that is connected with intercooler, be fixed together through sulfuration process between two tube heads and the inboard wall of tube body, the diameter of two tube head the inners is greater than the diameter of spout part, its longitudinal section is bell mouth shape, being connected between tube head and the body is more firm, be provided with the twice circle hoop 3 of evagination at interval in body 2 peripheries simultaneously, the wall thickness at circle hoop 3 places is about 2 times of body 2 wall 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 comprises the body of being made by rubber material (2), it is characterized in that being connected in two ends of body (2) tube head (1) that is connected with diesel pressure booster and the tube head (4) that is connected with intercooler.
