Description
Technical field
The present invention relates to a kind of air compressor machine, particularly relate to a kind of main air compressor machine of electronic oil-free, belong to air compressor skill
Art field.
Background technology
Oil-free air compressor is the main body in compressed air source unit, and it is the mechanical energy of prime mover (typically motor) to be turned
Changing the device of gas pressure energy into, be compressed-air actuated pressure generator, have oil and oil-free in air compressor machine typically all refer to
Air compressor exhaust port discharge the oil content of gas number, typically have oil machine oil content relatively big, the oil content of oilless air compressor is
0.01ppm, another kind is the air compressor machine of oil-free, and it is not to use to have oil lubrication, but uses resin material lubrication, so
Whole expellant gas not oil-containing is referred to as Whole oiless idling press, but easily runs off due to the grease sealed up till now planting air compressor machine
Causing bearing dry grinding to damage, quality is not the most satisfactory, domestic general be have oil lubrication without oil machine, the most up-to-date grind
Making a kind of Whole oiless idling press improved on the basis of former Whole oiless idling press, this Whole oiless idling press employs thermal resistance piston,
Bearing grease is made no longer to be run off, so that the Whole oiless idling press life-span is greatly prolonged, for rail with radiating by high temperature conduction
The electronic oil-free main air compressor machine part of road vehicle main air origin system, the most mostly uses and improves compressed air by oil is cold
Quality, and this by oil cold improve compressed air quality by the way of exist air compressor machine leakage of oil and string oil risk hidden danger ask
Topic, this kind of mode regular maintenance cost is high.
The Chinese utility model patent of such as Authorization Notice No.: CN201381981Y, this utility model relates to a kind of oil-free
The piston ring of air compressor machine, including ring body, ring body has upper side and downside, and it it is critical only that piston ring is split ring, this
Piston ring improves the sealing between oilless air compressor piston ring and cylinder wall, and the maximum making the oilless air compressor of single-stage cylinder is defeated
Going out pressure and brought up to 1.9MPa by former 1.4MPa, this utility model is by piston ring movement locus straight up and down, ring body
Upper side and downside, the friction to casing wall is little, and piston ring scuffing also reduces, improve the life-span, reduce loss；For another example publication number
CN103711675A Chinese invention patent, this invention relates to the piston of a kind of oilless air compressor, including piston rod and be located at
The piston plate on the top of piston rod, on piston plate upper surface, pressure is provided with and fixes the pressing plate being connected with piston rod, under pressing plate
Between end face and piston plate upper surface, pad is provided with pad, and the edge of pressing plate offers a circle groove, is provided with rubber seal in groove
Circle, the edge part of pad is by the rubber seal being upturned outside interior and part envelopes, and the advantage of this invention is to prevent from living
The sealing member of plug softens because piston the most quickly rubs with cylinder body, causes cylinder body or the damage of piston, scuffing of cylinder bore, stuck
Phenomenon, it is by directly or indirectly reducing maintenance cost, reduces maintenance difficulty；Above-mentioned technology is all to oil-free of the prior art
The performance of air compressor machine is improved, and has certain effect, but, current oilless air compressor still suffers from air compressor machine leakage of oil
