Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of air compressor machine, more particularly to a kind of double end Oil-free Mechanical Vacuum Pump
Air compressor machine.
Background technology
Air compressor abbreviation air compressor machine, is the main body in compressed air source unit, and it is that the mechanical energy of prime mover is converted into gas
The device of body pressure energy, is the pressure generator of compressed air.But traditional air compressor noise is big, the gas of discharge
Oil-containing water is big, therefore environment is impacted.With industry develop rapidly, and people's living standard continuous improvement,
Particularly medical air compressor machine, the control requirement of noise and oily pollution to compressor is very high.
For the problem present on, people have carried out continuous improvement to compressor, therefore occur in that Jing Yin oil-free is empty
Air compressor.Jing Yin oil-free air compressor is belonging to Miniature reciprocating piston compressor, and its operation principle is：Motor single-shaft
When driving compressor crank shaft to rotate, by the transmission of connecting rod, just do past without the piston of any lubricant with self-lubricating
Multiple motion, the swept volume being made up of cylinder inner wall, cylinder head and piston-top surface then can generating period change.Piston type pressure
From at cylinder head during setting in motion, the swept volume in cylinder gradually increases the piston of contracting machine, and at this moment, gas is along air inlet
Pipe, pushes intake valve open and enters cylinder, and untill when swept volume changes to maximum, intake valve is closed；Piston compressor
When piston reverses direction is moved, swept volume is reduced in cylinder, and gas pressure is raised, when inner pressure of air cylinder reaches and is slightly above exhaust pressure
During power, air bleeding valve is opened, gas discharge cylinder, until piston movement is to extreme position, exhaust valve closure.
Compared to traditional air compressor machine, above-mentioned Jing Yin oil-free air compressor reduces its noise very much to a certain extent greatly
Control, has also accomplished that the gas of oil-free can be discharged.But its air inlet is arranged in cylinder block with exhaust outlet, equivalent to gas
, by compression variation, its flowing stroke space is narrow and small, causes for the swept volume constituted in cylinder inner wall, cylinder head and piston-top surface
Compressed gas are high with the collision frequency of cylinder inner wall, and then the noise generation between also 50 decibels to 60 decibels, exceeded existing
There is the noise of compressor of air conditioner.Therefore further the control of lifting air compressor machine noise is problem demanding prompt solution on present society.
The content of the invention
The purpose of this utility model is directed to the above-mentioned problems in the prior art, there is provided a kind of long lifespan, noise
Low double end Oil-free Mechanical Vacuum Pump air compressor machine.
The purpose of this utility model can be realized by following technical proposal：A kind of double end Oil-free Mechanical Vacuum Pump air compressor machine, bag
Fixed seat and the motor being fixed in fixed seat, and two crankcases are included, two described crankcases are connected to motor
Left and right both ends, be respectively arranged with two cylinders on two described crankcases, it is characterised in that two described crankcases
Interior end is provided with inlet plenum, by spacers block between described inlet plenum and crankcase inside, on described dividing plate
The passage being connected with inside crankcase is offered, the outer end of crankcase is provided with the Intake Cover for covering inlet plenum, described
Fixed seat on be provided with muffler, and the bottom of muffler is provided with air admission hole, connects between described muffler and Intake Cover
It is connected to the air inlet pipe that extraneous air can be sucked by air admission hole in inlet plenum.
In a kind of above-mentioned double end Oil-free Mechanical Vacuum Pump air compressor machine, revolved by screw thread between described Intake Cover and crankcase
Tightly.
In a kind of above-mentioned double end Oil-free Mechanical Vacuum Pump air compressor machine, joint phase is passed through between described air inlet pipe and Intake Cover
Even.
In a kind of above-mentioned double end Oil-free Mechanical Vacuum Pump air compressor machine, described fixed seat bottom is provided with mounting seat, described
Mounting seat and fixed seat between by it is some with damping spring connect.
Compared with prior art, this double end Oil-free Mechanical Vacuum Pump air compressor machine is provided with inlet plenum, extraneous air in crankcase
Inlet plenum is inhaled into by the air admission hole on muffler, subsequently into crankcase, air is in by compression and the process of circulation
Stroke becomes big, and damping spring is provided between fixed seat and mounting seat so that air compressor machine stability operationally
More preferably, therefore noise is substantially reduced, service life also increases,.
