To use aluminum alloy materials as agent structure, so that lightweight air compressor machine assembly.
Embodiment 2
A kind of air-cooled electric compressor of noise reduction, it is similar to Example 1, except that, air entry 8 is arranged on suction muffler.This
Sample, it is possible to increase gettering efficiency.
It is preferred that, suction muffler is arranged on the middle position of discharge chamber 9.In such manner, it is possible to further promote automobile in traveling
When, by the cold air sucked in, the delivery temperature in discharge chamber 9 is taken away, plays a part of radiating and cooling, i.e., with thermal convection current
Pattern reduces the delivery temperature of air compressor machine.
Embodiment 3
A kind of air-cooled electric compressor of noise reduction, it is similar to Example 2, except that, noise reduction resonant cavity 4 is arranged on cylinder cap valve plate
The inside of component 12.In such manner, it is possible to preferably reduce noise by resonance sound-absorbing, Jing Yin effect is played.
It is preferred that, the hole moved back and forth for air column is provided with noise reduction resonant cavity 4.In such manner, it is possible to better profit from sky
Back and forth friction of the gas column in aperture carrys out sound energy consumption, and transit chamber controls the resonant frequency of sound absorption peak value deeply, so that further
Air compressor machine noise is reduced, it can make the noise of air compressor machine decline 10 ~ 8 decibels by sqouynd absorption lowering noise.

When dynamic or during cold-starting, it is to avoid hypertonia, the lubrication pressure of system can be protected stable.
Embodiment 5
A kind of air-cooled electric compressor of noise reduction, it is similar to Example 4, except that, it is provided with cylinder cap valve board assembly 12 scattered
Backing 10.In such manner, it is possible to further be cooled down by the flow velocity of natural wind, air compressor machine heat is taken away, so as to further improve
Radiating and cooling effect.
It is preferred that, fin 10 is set to the annular that inner diameter edge is connected with the outer wall of connecting rod piston component 3.This
Sample, conveniently can process and install.
It is preferred that, the quantity of fin 10 is at least two, and is uniformly distributed in parallel to each other.In such manner, it is possible to improve scattered
Thermal uniformity effect.
The air-cooled electric compressor of noise reduction of the present invention, it uses Double-cylinder piston type structure, during its work, is driven by motor 11
The bent axle 1 of air compressor machine is rotated, and drives lubrication pump 2 to work by bent axle 1, gives air compressor machine moving parts, i.e. connecting rod piston component 3
Force feed is provided, and takes away the heat on air compressor cylinder body inwall, oil return to support fuel tank 7.
During compressor operation, the exhaust valve plate in its chatter, grating and cylinder cap valve board assembly 12 is impacted by air pressure
The comprehensive reverberation sound such as grating, reflected sound of lap up and down, air-flow and casing wall passes through the integrated multiple Hai Muhuo of air compressor machine
Hereby the noise reduction resonant cavity 4 of resonator is arranged, gives sqouynd absorption lowering noise, and its sqouynd absorption lowering noise mechanism is：The air column class of resonant cavity eck
Like piston, with certain acoustic mass, closed cavity is similar to air spring, and with certain elasticity, the two composition one is altogether
Vibrating system.When sound wave reaches eck, air column produces vibration under acoustic pressure effect, and frictional damping during vibration makes a part of sound
Thermal energy consumption can be converted to dissipate.Simultaneously as the suddenly change of acoustic impedance, a part of acoustic energy will reflect back into sound source.Work as sound
When wave frequency rate is identical with resonant cavity intrinsic frequency, resonance is just produced, air-column vibration speed reaches maximum, the sound now consumed
Can at most, sound deadening capacity is also just maximum.
In compressor operation due to pipeline damage bending or block, or due to the low temperature of -35 DEG C of natural environment presence,
Gas exhaust piping is it sometimes appear that freeze, and these situations can cause the pressure at expulsion of air compressor machine infinitely to rise, and ultimately result in blast pipe
Path loss is bad or air compressor machine is damaged, therefore designed pressure protection valve 5 can be opened in the case of setup pressure value, protect product
Be not stressed damage.
When rotational speed of air compressor is specified, influenceed by low temperature, lubricating oil viscosity is larger, cause grease pump 2 run when
Pressure is excessive, and overflow valve 6 has been internally integrated in grease pump 2 during design, and the Opening pressure of overflow valve 6 is reached when pressure is overproof
When, pressure off-load to system pressure, protection product lubricating system oil circuit pressure is stable.
Air compressor machine works long hours under pressure, can produce substantial amounts of heat, produces various failures because temperature is too high sometimes,
Therefore air entry 8 is set in the middle of discharge chamber 9, when air compressor machine air-breathing, the gas temperature of suction is environment temperature, is far below
Work exhaust cavity temperature, by thermal convection current, breathing process reduces the temperature of discharge chamber 9；Air compressor machine assembly work on automobile
When making, the time of automobile 90% is in running status, whole air compressor cylinder cover, cylinder body, the temperature of valve seat plate surface, by designed
Fin 10 cooled down by natural wind, with realize be rapidly reached reduction product assembly surface temperature.
Although above with general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements, belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
