Abstract
The utility model discloses a balanced slide compressor which comprises a stator (1), a rotor (3), a slide (2), and an end housing (4). The utility model is characterized in that the surface contour lines of the inner hole of the stator (1) are symmetric up and down and composed of a plurality of segments of curves. The cylindrical rotor (3), which is provided with the slide (2), is installed concentrically on the inner hole of the stator (1), forming a semilunar upper working region A and a semilunar lower working region B. Compared with the prior art, the utility model not only dramatically reduces the power consumption of friction (approximately reduced by 75%), but also lengthens the service life and reduces the work noise remarkably.
Description
The utility model relates to a kind of variable capacity air pump, particularly a kind of rotary type slide plate elastic fluid compressor.
Existing various rotary type slide plate elastic fluid compressor all is single, and promptly the working surface of stator is a cylndrical surface (big column hole), is placed in the stator rotor eccentricity, and slide plate is contained in the epitrochanterian groove, can slide flexibly in groove.During the rotor revolution, because action of centrifugal force, the top of blade is close on the inner surface of stator, has just formed the active chamber of sealing one by one between the end cap at stator, rotor, per two slide plates and two.Rotor is in turning course, and the volume of described active chamber changes from small to big from large to small again, gas is sucked from intakeport extrude from relief opening again.Because the gas pressure that above-mentioned compressor is subjected on when work rotor is unbalanced, thus on the rotor shaft except that torsional interaction is arranged, also have the effect of additional bending moment.This additional bending moment caused stress on the rotor shaft section is symmetry circulating stress, so there is following deficiency in it: 1, the surface friction drag of rotor shaft two supporting is big, and not only kinetic equation loss is big, and efficient is low, and mechanical wear is fast, reduction of service life; 2, the requirement of strength height of rotor shaft, sectional area is big.
In view of the above-mentioned deficiency of existing in prior technology, the purpose of this utility model provides a kind of balanced type slide vane compressor, and during work, the gas pressure that is subjected on the rotor is a balance, does not have additional bending moment, and surface friction drag is little.
Another purpose of the present utility model is to disclose a kind of balanced type slide vane compressor with higher compression ratios.
The utility model realizes that the above-mentioned purpose technical solution is: a kind of balanced type slide vane compressor, comprise stator, be placed in rotor in the stator inner hole, be installed in epitrochanterian slide plate and be located at rotor two and be fixed on end cap on the stator, the surface profile line that it is characterized in that stator inner hole is symmetry and be put together by the plurality of sections curve up and down, the cylindrical rotor that slide plate is installed is installed in the endoporus of stator with one heart, forms meniscate working area A of going up and following working area B.
The utility model realizes that the feature of above-mentioned another purpose technical solution is the described meniscate surface profile line length of going up the more air-breathing district of the surface profile line stator inner hole that calming the anger of working area A and following working area B distinguish stator inner hole, make the seal operation chamber of the seal operation chamber in the district of calming the anger more than air-breathing district, to realize multistage compression, obtain higher compression ratio.
Because the active chamber of the utility model rotor both sides is symmetrical, the gas pressure that is subjected on the rotor when therefore working is a balance, can not produce additional moment of flexure on the rotor shaft, the frictional force of two supporting is little, kinetic equation loss is low, and high working efficiency is also little than the sectional area of same specification product rotor shaft; Again because the surface profile line length of the more air-breathing district of the surface profile line stator inner hole of the district's stator inner hole of calming the anger of described meniscate upward working area A and following working area B although therefore form two working areas in a stator, also can obtain higher compression ratio.In addition, finish twice air-breathing and action of calming the anger because rotor described in the utility model whenever circles, therefore the air displacement than prior art nearly doubles under the constant situation of rotating speed.
Below in conjunction with accompanying drawing and a preferred embodiment the utility model is carried out further detailed description, implement technological means of the present utility model so that the public grasps better.
Description of drawings:
Fig. 1 is the structural representation of a preferred embodiment of the utility model;
Fig. 2 is the A-A sectional view of Fig. 1.
Embodiment:
Referring to Fig. 1, stator 1 is provided with the endoporus of laying rotor 3, and the surface profile line of this endoporus is symmetry and be ρ=R (1-ε cos(a θ+b)-ε by polar equation up and down
2/ 2sin
2(a θ+b)) curve constituted, R is the mean radius of stator inner hole in the formula, r is a rotor radius in ε=(R-r)/R(formula), span is 0.08～0.15.Referring to Fig. 1, the cylindrical rotor 3 that eight slide plates 2 are installed is placed in the endoporus of stator 1 with one heart, at stator 1, rotor 3, end cap 4(is referring to Fig. 2 up and down) between form meniscate working area A of going up and following working area B.
Referring to Fig. 1, in being 0≤θ in the above-mentioned polar equation≤π/4 intervals, the air-breathing district of last working area A gets a=4, b=0; The district of calming the anger at last working area A is that π in the above-mentioned polar equation/4＜θ≤π gets a=4/3 in the interval, b=2/3 π.Referring to Fig. 1, the air-breathing district of following working area B calm the anger the district in 5/4 π＜θ＜2 π, and the surface profile line of stator 1 endoporus of the surface profile line of stator 1 endoporus and last working area A is symmetrical in true origin in π＜θ≤5/4 π.Span by θ, a and b in the above-mentioned polar equation can be found out significantly, the surface profile line length of the more air-breathing district of surface profile line stator 1 endoporus of district's stator 1 endoporus of calming the anger of described meniscate upward working area A and following working area B.Like this, the formed seal operation chamber, district of calming the anger is beneficial to realize multistage compression then more than formed seal operation chamber, air-breathing district, obtains higher compression ratio, and can not cause air displacement to increase and the adverse consequences of compression ratio reduction.
Compare not only by the product of similar same specification in the made balanced type slide vane compressor of the foregoing description and the prior art that friction power loss descends significantly (descending 75% approximately), and long service life, operational noise also reduces significantly.
