Description
Technical field
The present invention relates to a kind of air compressor machines to belong to air compressor skill more particularly to a kind of electronic oil-free main air compressor machine
Art field.
Background technique
Oil-free air compressor is the main body in compressed air source unit, it is to turn the mechanical energy of prime mover (usually motor)
The device for changing gas pressure energy into, is the pressure generator of compressed air, has oil typically to refer to oil-free in air compressor machine
Air compressor exhaust port be discharged gas oil content number, generally have oil machine oil content larger, the oil content of oilless air compressor is
0.01ppm, another kind are the air compressor machines of oil-free, it using there is oil lubrication, is not lubricated, so most using resin material
Oil-containing is not known as Whole oiless idling press to the gas being discharged eventually, but such air compressor machine was lost since the lubricating grease of sealing is easy in the past
Cause bearing to dry grind and damage, quality be not it is very satisfactory, it is domestic it is general be have oil lubrication without oil machine, it is present newest to grind
A kind of Whole oiless idling press improved on the basis of former Whole oiless idling press is made, this Whole oiless idling press has used thermal resistance piston,
Bearing grease is set no longer to be conducted by high temperature with radiating and be lost, to make the Whole oiless idling press service life greatly prolong, for rail
Compressed air is improved using by the way that oil is cold mostly at present in the electronic oil-free main air compressor machine part of the main air supply system of road vehicle
Quality, and it is this cold come there are the risk hidden danger of air compressor machine oil leak and string oil to ask by way of improving compressed air quality oil
Topic, this kind of mode regular maintenance cost are high.
Such as Authorization Notice No.: the Chinese utility model patent of CN201381981Y, the utility model are related to a kind of oil-free
The piston ring of air compressor machine, including ring body, ring body have upper side and downside, and key is that piston ring is split ring, this
Piston ring improves the leakproofness between oilless air compressor piston ring and cylinder wall, keeps the maximum of the oilless air compressor of single-stage cylinder defeated
Pressure is increased to 1.9MPa by pervious 1.4MPa out, the utility model be by piston ring motion profile straight up and down, ring body
Upper side and downside, small to the friction of casing wall, piston ring scuffing also reduces, improve the service life, reduce loss；For another example publication number
CN103711675A Chinese invention patent, the invention are related to a kind of piston of oilless air compressor, including piston rod and are set to
The piston plate on the top of piston rod, pressure is equipped with the pressing plate being fixedly connected with piston rod on piston plate upper surface, under pressing plate
Pad is equipped with gasket between end face and piston plate upper surface, and the edge of pressing plate offers a circle groove, is equipped with rubber seal in groove
Circle, by the rubber seal that is upturned except interior and part envelopes, the advantages of invention is to prevent from living for the edge part of gasket
The sealing element of plug softens because piston quickly rubs for a long time with cylinder body, causes the damage of cylinder body or piston, scuffing of cylinder bore, stuck
Phenomenon is to reduce maintenance difficulty by directly or indirectly reducing maintenance cost；Above-mentioned technology is in the prior art oil-free
The performance of air compressor machine is improved, have the effect of it is certain, however, there are still air compressor machine oil leaks in current oilless air compressor
With the risk potential problem of string oil, this results in its regular maintenance cost high.
