Description
Technical field
The invention belongs to field of mechanical technique, relate to a kind of air compressor machine, particularly to a kind of Novel sound-silencing oilless air compressor.
Background technology
Air compressor is called for short air compressor machine, is the main body in compressed air source unit, and it is the device that the mechanical energy of prime mover is converted into gas pressure energy, is compressed-air actuated pressure generator.But traditional air compressor noise is big, the expellant gas oil-containing water yield is big, therefore impacts environment.Along with developing rapidly of industry, and the improving constantly of people's living standard, particularly Medical air press, the noise of compressor and the control of greasy dirt dye are required the highest.
For with present on problem, people have carried out continuous improvement to compressor, have therefore occurred in that quiet oil-free air compressor.Quiet oil-free air compressor is belonging to Miniature reciprocating piston compressor, its operation principle is: when motor single-shaft drives compressor crank shaft to rotate, by the transmission of connecting rod, having a self-lubricating and piston without any lubricant just moves reciprocatingly, the swept volume being made up of cylinder inner wall, cylinder head and piston-top surface then can generating period change.The piston of piston compressor is at cylinder head during setting in motion, and the swept volume in cylinder is gradually increased, and at this moment, gas, i.e. along air inlet pipe, is pushed intake valve open and entered cylinder, and during until swept volume changes to maximum, intake valve cuts out；During the piston reverses direction motion of piston compressor, in cylinder, swept volume reduces, and gas pressure raises, when inner pressure of air cylinder reaches and during slightly above pressure at expulsion, and air bleeding valve is opened, and gas discharges cylinder, until piston movement is to extreme position, exhaust valve closure.
Comparing traditional air compressor machine, above-mentioned quiet oil-free air compressor reduces very greatly the control of its noise to a certain extent, has also accomplished to discharge the gas of oil-free.But its air inlet and air vent are arranged in cylinder block, be equivalent to swept volume that gas constituted at cylinder inner wall, cylinder head and piston-top surface by compression variation, its flowing stroke space is narrow and small, cause compressed gas high with the collision frequency of cylinder inner wall, and then also noise between 50 decibels to 60 decibels produces, and has exceeded the noise of existing compressor of air conditioner.The control promoting air compressor machine noise the most further is problem demanding prompt solution on present society.
Summary of the invention
It is an object of the invention to for the above-mentioned problems in the prior art, it is provided that a kind of life-span is long, the Novel sound-silencing oilless air compressor that noise is low.
nullThe purpose of the present invention can be realized by following technical proposal: a kind of Novel sound-silencing oilless air compressor，Including base and the crankcase being fixed on base，Several cylinders it are provided with on described crankcase，Described cylinder is by cylinder body、Cylinder cap and piston composition，It is provided with bent axle in described crankcase，Described bent axle is connected with the piston in several cylinders respectively by several connecting rods，It is characterized in that，Offer on the sidewall of described crankcase and the air inlet being connected inside crankcase，Steam vent is offered on the sidewall of described cylinder cap，Have on the periphery wall of described cylinder body and the gas channel being connected inside crankcase，Valve plate and lower valve plate it is provided with between described cylinder body and cylinder cap，Two valve blocks one it are provided with at the lower surface of described upper valve plate，Two valve blocks two it are provided with at the upper surface of described lower valve plate，Described upper valve plate all offers, with the corresponding position of lower valve plate, the airflow hole being connected with gas channel.
In above-mentioned a kind of Novel sound-silencing oilless air compressor, it is provided with pad between described upper valve plate and cylinder cap, between described upper valve plate and lower valve plate, is also equipped with pad.
In above-mentioned a kind of Novel sound-silencing oilless air compressor, the both sides that described outer wall of cylinder block is positioned at gas channel are uniformly distributed with several U-shaped fin and bar shaped fin, are provided with several bar shaped fin between two described adjacent U-shaped fin.
Compared with prior art, this Novel sound-silencing oilless air compressor has offered air inlet on crankcase, extraneous air is inhaled in crankcase by the air inlet of crankcase, and it is provided with the gas channel for crankcase air circulation on outer wall of cylinder block, air is being become big by the stroke in compression and the process of circulation, diminishing the most therewith with the collision frequency of cylinder cap, therefore noise is substantially reduced, and service life also increases.
