Abstract
The utility model discloses an air compressor air intake resonator assembly which comprises an air intake pipe. The air compressor air intake resonator assembly is characterized in that the air intake pipe is connected with an air inlet of an air compressor, the air intake pipe is vertically connected with a resonant cavity, and the tail end of the resonant cavity is connected with a sealing plug in a sealed mode. The air compressor air intake resonator assembly is simple in structure, easy to machine and manufacture, and capable of lowering noise of the air compressor and improving performance of the air compressor.
Description
Technical field
The utility model relates to the air compressor field, specifically, relates to a kind of air compressor air intake resonator assembly.
Background technique
The heavy truck air compressor can provide the pressurized air of braking use for the car load braking system, be the pith of vehicle.Air compressor can produce certain vibrating noise in running, affects the performance of air compressor.This is the deficiencies in the prior art part.
The model utility content
?the technical problems to be solved in the utility model is to provide a kind of air compressor air intake resonator assembly, can reduce the noise of air compressor, improves the performance of air compressor.
The utility model adopts following technological means to realize goal of the invention:
A kind of air compressor air intake resonator assembly, comprise suction tude, it is characterized in that: described suction tude is connected with the air compressor air intake mouth, and described suction tude is connected with resonant cavity is vertical, and the end seal of described resonant cavity connects sealing plug.
As the further restriction to the technical program, described resonant cavity and sealing plug sulfuration are integrated.
As the further restriction to the technical program, described suction tude is rubber pipe.
As the further restriction to the technical program, described sealing plug is cylindrical.
Compared with prior art, advantage of the present utility model with good effect is: suction tude of the present utility model is connected with the air compressor air intake mouth, guarantee the normal air inlet of air compressor, when air inlet when the air compressor air intake valve block is closed, converse backflow occurs in the air moment that enters suction tude, and then suck new air-flow when next intake stroke, both meetings collide near suction tude, when sound wave passes to the aditus laryngis place of suction tude resonant cavity, the sound wave at aditus laryngis place is under the effect of pressure, to-and-fro motion, because resonant cavity has certain quality, it can resist the velocity variations caused due to sound wave effect, friction and the damping function of tube wall are converted into heat energy by acoustic energy, when the natural frequency of the frequency of sound wave and resonator is identical, the acoustic energy absorbed will be maximum, thereby realize falling low noise target.The utility model simple structure, easily manufacturing, can reduce the noise of air compressor, improves the performance of air compressor.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model preferred embodiment.
The suction tude sectional drawing that Fig. 2 is the utility model preferred embodiment.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is further described in detail.
Referring to Fig. 1 and Fig. 2, the utility model comprises suction tude 1, sealing plug 2 resonant cavity 3, and described suction tude 1 is connected with the air compressor air intake mouth, and described suction tude 1 is connected with resonant cavity 3 is vertical, and the end seal of described resonant cavity 3 connects sealing plug 2.
Described resonant cavity 3 and sealing plug 2 sulfurations are integrated.
Described sealing plug 2 is cylindrical.
Described suction tude 1 is rubber material, with the air compressor air intake mouth, is connected, and guarantees the normal air inlet of air compressor.When air inlet when the air compressor air intake valve block is closed, converse backflow occurs in the air moment that enters suction tude 1, and then suck new air-flow when next intake stroke, both meetings collide near suction tude 1, when sound wave passes to the aditus laryngis place of suction tude 1 resonant cavity 3, the sound wave at aditus laryngis place is under the effect of pressure, to-and-fro motion, because resonant cavity 3 has certain quality, it can resist the velocity variations caused due to sound wave effect, friction and the damping function of tube wall are converted into heat energy by acoustic energy, when the natural frequency of the frequency of sound wave and resonator is identical, the acoustic energy absorbed will be maximum, thereby realize falling low noise target.Described resonant cavity 3 is connected with suction tude 1 is vertical, and the length of resonant cavity 3 is determined according to factors such as the resistance of gas handling system, air inflows.Improve the charging efficiency of air compressor when the middle low speed of motor, when reducing inflow noise, improved the performance of vehicle power.
Described sealing plug 2 is at the end of resonant cavity 3, together with resonant cavity 3 is sulfided into, with resonant cavity 3, forms enclosed spaces, along with the difference of the volume of resonator will be eliminated the induction noise of different frequency, requires in the situation that negative pressure can keep sealing simultaneously.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
