Abstract

Provided is a method for forming a full-clearance-free compressor structure through an end-clearance-free V-shaped nonmetal piston ring. The full-clearance-free compressor structure ensures that a full-clearance-free instantaneous contact state without any geometric space can be formed among a piston (5), a discharge valve plate (3), a conical air suction valve block (4), a cylinder (6) and the piston ring (U) in the air suction process. A mounting method adopting the end-clearance-free V-shaped nonmetal piston ring is the same as the method for mounting a cover tyre on a bicycle steel rim in a sleeving mode. Through the full-clearance-free instantaneous contact state, a piston reciprocating compressor can have a brand-new appearance, namely, conditions are created for enabling the piston gas displacement to reach 100% or greatly improving the compression ratio; the compressor of the full-clearance-free compressor structure can become an upgraded product for the piston reciprocating compressor, and may even become an upgraded product for compressors of most types due to extremely high cost performance of the compressor.

Description

Technical field
The present invention relates to the technology of piston reciprocating compressor, particularly relate to the method adopting the nonmetal piston ring formation of V-type end-clearance-free completely without clearance compressor arrangement.
Background technique
Great majority in the compressor kind of current appearance are all the conventional piston compressors by crank-driven, it has: manufacture simple, long service life, cannot Comprehensive Characteristics by comparison to other kind compressor of the less demanding grade of material, this has been prolonged not sad main cause since its comes out.
Piston reciprocating compressor is the same with other compressors, and owing to being structurally subject to the puzzlement of insurmountable " clearance " problem, therefore its exhaust efficiency is or/and compression ratio is difficult to improve all the time.---such as: when compression ratio is close to " 10 ", its air displacement will be reduced to the degree losing its work meaning.
" clearance " in existing piston reciprocating compressor comprising: outer " clearance " that must exist with both exhausts mechanism between top and cylinder inner top and due to air-breathing of piston, and the clearance caused due to the existence of piston ring.
Patent CN1680717A discloses a kind of structural type of " without clearance " piston reciprocating compressor without piston ring.
In addition, JP8-9985B2 discloses a kind of without oily piston reciprocating compressor, this compressor have employed the piston ring that the polymer that comprises such as teflon (PTFE) or polyflon is made, but, in its structure, it is so inevitable that the end gap existence of this piston ring is appointed, and namely the tip-clearance of C type piston ring is appointed is so inevitable.
In addition, JP8-9985B2 discloses a kind of without oily piston reciprocating compressor, this compressor have employed the piston ring that the polymer material that comprises such as teflon (PTFE) or polyflon is made, but, in its structure, the end gap existence of this piston ring remains inevitable, and namely the tip-clearance of C type piston ring remains inevitable.
Summary of the invention
The object of the present invention:
Propose exactly a kind of piston displacement can reach 100% have employed the structural type that its cross section is " completely without clearance " piston reciprocating compressor type of the nonmetal piston ring of end-clearance-free of V-type.
In order to realize foregoing invention object, intend adopting following technology:
On the basis of the prior art model structure that the present invention runs at piston reciprocating, its structure and material meet again three organization establishes conditions of following a, b and c:
A. the top outer adapted of piston controls the taper Aspirating valves block that suction port opens and closes;
B. at least with the outside and top flush position of piston on to be provided with its section be the nonmetal piston ring of V-type end-clearance-free, and; This piston ring adopts as nonmetal and can make the soft macromolecule polymer material of oil resistant heatproof of deformation;
C. piston is in forward compression exhaust stroke, finally can back down exhaust valve plate and go out cylinder, piston is in backward travel, when piston is for returning in cylinder completely, be about to and the moment being blocked in outer exhaust valve plate by cylinder and being separated, piston will be formed, exhaust valve plate, taper Aspirating valves block, its section be form " completely without clearance " instantaneous touch state not having geometric space between the nonmetal piston ring of V-type end-clearance-free and cylinder;
Installation method crucial between the nonmetal piston ring of end-clearance-free V-type of the present invention and piston ring:
Utilize the assistance of instrument the piston ring be made up of macromolecule polymer material of deformation can press down allowing under brute force from piston head like that as installing cycle casing on steel ring and allow it progressively embed completely the annular groove of piston;
The described nonmetal piston ring of V-type end-clearance-free is acute angle at the angle with the V-shaped section shape in the flush position of piston outer top, and towards the piston center of circle, formed between it and piston in the surface of contact tilted, this section is that the nonmetal piston ring of V-type end-clearance-free of acute angle is being subject to will being fitted in more closely under gas pressure with on the surface of contact of the above-mentioned inclination in the flush position of this piston outer top, and the extruding component produced towards cylinder inner circumference direction, the precondition realizing producing this extruding component is:
The planar section of one end section acute angle in the embedding piston ring connected in star of the nonmetal piston ring of this V-type end-clearance-free be arranged on piston for locating the planar annular in the annular groove of this piston ring, there is gap between the two, should both can not contact when piston reciprocating runs, and when piston carries out calming the anger stroke, can guarantee that the face of slope of this piston ring and the piston head in acute angle section is mutually in identical state contacts;
---described exhaust valve plate is the top being positioned at cylinder by the elastic device of spring one class.
---the temperature rise control method of structure of the present invention under high compression ratio operating mode: adopt the water-cooling pattern as explosive motor to be solved.
Feature of the present invention:
One, due to the present invention adopt its section be V-type end-clearance-free as nonmetal and can the piston ring structure made of the soft macromolecule polymer material of oil resistant heatproof of deformation, this is just for allowing:
Piston ring can be installed easily (packing into bicycle rim like that as cycle casing) the Special annular groove on piston implements simple Positioning Creates condition;
The piston ring of this V-type end-clearance-free utilize when pressurized gas the inclination contact between piston produce the extruding of the component countercylinder inwall towards cylinder inner circumference, limit piston high and low pressure two ends air leakage amount, be the sealing increased between piston ring and cylinder, for the work compression ratio of " completely without the clearance " structure improving this piston reciprocating type type creates condition.------, after one end that V-type piston ring is vertical is damaged, commutation of can also turning around continues to use.
Two, in view of high workload compression ratio required in common engineering is all limited or very limited, this as: if technically can build ten thousand layers of high buildings and large mansions, and in fact the high buildings and large mansions of people's demand are just enough the same close to hundred layers, and this is just for allowing:
Under adopting the not enough reality of nonmetallic macromolecular material as heat-resisting (hereafter will seminar relate to the problem of cooling heat dissipation) endurance (with Metal Phase than the problem such as aging being difficult to avoid) of piston ring actually, but, still can replace in the Applicable scope of " task compression ratio " and the metallic piston ring of structure " end gap " (" end gap " will restrict the soaring of high compression ratio) cannot be avoided and extensive use creates condition.

Embodiment
Fig. 1 illustrates a kind of structure in general of crank-driven type piston reciprocating compressor " completely without clearance ", and it belongs to the most practical typical type of the large air displacement of horizontal low reciprocating frequence.
Fig. 2 illustrates piston 5 when compression exhaust stroke forward, carries the nonmetal piston ring U of V-type end-clearance-free F together, heads on the situation that exhaust valve plate 3 is advanced together in outside, the hole of cylinder 6, obviously:
A., before piston 5 contacts with exhaust valve plate 3, this has just defined the high pressure air cushion will alleviating piston 5 and the mutual collision dynamics of exhaust valve plate 3 therebetween in cylinder 6;
B. now mean: the pressurized gas be compressed into all are clamp-oned zone of high pressure H by piston 5;
C. should guarantee in structural design: the nonmetal piston ring U of V-type end-clearance-free F all can not depart from the hole of (going out) cylinder, otherwise this piston ring U just again can not be carry by piston 5 and return cylinder 6; In addition, piston 5 goes out the itinerary part at cylinder 6 hole, can be controlled in about 1/10th or less of its effective travel length.---the itinerary part that this piston 5 goes out cylinder 6 hole is larger, the action time that high pressure gas participation driven plunger 5 in the H of zone of high pressure returns cylinder 6 is longer, the quantity that namely can reduce the low-pressure gas that low pressure area W that this piston 5 sucks in suction stroke afterwards provides will reduce, and affects the total exhaust quantity of complete machine within the unit time afterwards.---the stroke length that this piston 5 goes out cylinder 6 hole determined by the length of its crankshaft-link rod.
Fig. 3 illustrates piston 5 state by the taper Aspirating valves block 4 inspiration low-pressure gas at its top when the suction stroke retreated.Obvious:
D. downflow type suction mechanism is structurally adopted to meet the model structure requirement of " completely without clearance " most.
E. when piston 5 is in the starting stage of backward travel, namely before the hole of the complete setback cylinder 6 of piston 5, first closed by the hole top of larger-diameter exhaust valve plate 3 by more small-bore cylinder 6, will be formed this moment:
Piston 5 (comprising the nonmetal piston ring U of V-type end-clearance-free F being positioned at its outer rim and top), taper Aspirating valves block 4, the state of " completely without clearance " of moment between exhaust valve plate 3 and cylinder 6.At the moment, the inflation process (Here it is should " completely without clearance " key feature of causing) as residual high pressure gas in prior art would not be there is, directly allow piston 5 enter to have suction stroke stage of actual air-breathing meaning, until filled up in the space in cylinder 6 between piston 5 to exhaust valve plate 3 by the low-pressure gas of inspiration.
In sum, from structural principle of the present invention, when piston 5 is in suction stroke of the present invention but not yet carries out air-breathing, namely mainly under anticyclonic driving, the moment that the hole top of cylinder 6 closes by exhaust valve plate 3 is allowed: most critical will be formed: piston 5, exhaust valve plate 3, taper Aspirating valves block 4, between cylinder 6 and five of V-type piston ring U, do not have " completely without clearance " instant contact state of geometric space.------make use of " completely without clearance " instant contact state this point, just can achieve " completely without clearance " type.
Its truncation surface is adopted to be the analysis of the beneficial effect of V-type piston ring about " completely without clearance " type:
Because piston 5 and above-mentioned V-type piston ring (it is dehisced towards the center of circle) are when pressurized gas, by one. (this gradient direction be leave the center of circle and towards circumference) that the fixed taper gradient contacts in the mode mutually extruded, like this, in the middle of the process of piston 5 pressurized gas, just will inevitably increase by one towards the additional press component (variable and be directly proportional to by the pressure of pressurized gas) on cylinder 6 circumferential inner wall direction; When by the pressure of pressurized gas, namely when positive pressure reaches the highest, so, prevent the dynamics of leaking gas between the high pressure at piston 5 two ends and low pressure by the above-mentioned additional component of this piston ring also just to reach maximum (being very beneficial for realizing high compression ratio operating mode) thereupon; And in the priming stroke stage (when the pressure of gas is not high) of piston 5 pressurized gas, the above-mentioned extruding component towards circumferencial direction will not exist or very little.
Obvious: above-mentioned along with this is raised by the pressure of pressurized gas the process that its above-mentioned " the additional press component towards periphery " also increase thereupon, be extremely beneficial in formation high compression ratio.---Here it is under the major premise of " completely without clearance ", adopts the key point place of V-type piston ring.
About the high pressure temperature rise of high compression ratio type of the present invention and the problem of cooling heat dissipation:
High compression ratio or extra-high compression ratio type will inevitably face for the high temperature rise problem compressor, this can adopt general air cooling way to solve, also the water-cooling pattern as motor car engine (being carried out the operation of driven plunger by the blast of gasoline high temperature) can be adopted to solve (belonging to prior art category), the existing method of the very high-power cooling heat dissipation that railway uses in rail motor set more can be adopted to be solved.---the present invention can design infinitely-great work compression ratio type, but, most compression ratios required for service condition is limited, or even it is very limited, such as: the engineering of what the limited compression needed most in prior art become when adopting unit of the present invention compression, need the high temperature rise problem solved will be simply too much; But, even if employ " completely without clearance " of the present invention type, also the form compared to prior art with more high-grade twin-stage or multistage compression engineering can be adopted according to actual conditions.
