It should be noted that it can also be integrated with lightweight twin-tub crankcase, and lightweight oil pump etc. is integrated with, it can
To use aluminum alloy materials as agent structure, so as to 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
On.In such manner, it is possible to improve gettering efficiency.
Preferably, suction muffler is arranged on the middle position of discharge chamber 9.In such manner, it is possible to further automobile is promoted to travel
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
The inside of valve board assembly 12.In such manner, it is possible to preferably reduce noise by resonance sound-absorbing, Jing Yin effect is played.
Preferably, 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 as to further

Sample, processing and installation can be facilitated.
Preferably, 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 utility model, it uses Double-cylinder piston type structure, during its work, by motor 11
Drive the bent axle 1 of air compressor machine to rotate, drive lubrication pump 2 to work by bent axle 1, give air compressor machine moving parts, i.e. connecting rod piston
Component 3 provides force feed, 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 the grating of upper and lower lap, air-flow and casing wall, reflected sound 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, there is certain acoustic mass, closed cavity is similar to air spring, has certain elasticity, and 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 the low temperature due to -35 DEG C of natural environment presence,
For gas exhaust piping it sometimes appear that freezing, 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 damages, therefore designed pressure protection valve 5 can be opened in the case of setup pressure value, protects 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, has been internally integrated overflow valve 6 in grease pump 2 during design, has reached the Opening pressure of overflow valve 6 when pressure is overproof
When, pressure off-load to system pressure, protection product lubricating system oil circuit pressure stabilization.
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 among 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 reduce product assembly surface temperature.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will
Seek the scope of protection.
