Five, embodiment
1, working principle
In Fig. 1, axis 2 and housing 1 agree with to be formed at A point (near certain limit) and seal, the inwall of slide plate 3 periphery and housing 1 agrees with to be formed and seals, slide plate 3 also seals, so the inner space of housing 1 is divided in three independently working area (Ji Tu1Zhong I district, II district, III districts) by axis 2 and slide plate 3 through the slip surface of axis 2; When axis 2 rotates, the volume in the space that respectively works alone constantly changes to maximum from minimum, minimumly does mechanical periodicity again from maximum changing to.The layout scope of low pressure valve 4 on housing extends to before and after B point (on Fig. 1 middle shell, dotted line is the scope of valve 4) from arc AB leaves A point certain distance; The layout scope of high-pressure valve 5 on housing is leaned near A point (leaving A certain distance) on arc AD.
When this pneumatic element is as compressor, axis 2 turns clockwise, from low voltage terminal valve 4 suction gas when working space volume changes from small to big, working space volume from large to small time gas compressed and discharges from high voltage terminal valve 5.
When this pneumatic element is as pneumatic motor, axis 2 is rotated counterclockwise, and sucks certain gas when working space volume changes from small to big from high voltage terminal valve 5, afterwards, working space volume becomes large further, high pressure gas expansion, and when working space volume reaches maximum, gas expansion process terminates; Afterwards, working space volume from large to small time, gas is discharged from low voltage terminal valve 4.
2, this element is as specific works procedure declaration during compressor
In Fig. 1, when axis is rotated in a clockwise direction under external force drives, this element is by compressor operating.
Below for I district, the concrete condition of this pneumatic element by compressor operating is described.For ease of explanation, now be arranged in the horizontal position of X=A, Y=C with slide plate for initial position (axis is got back to initial position along being rotated counterclockwise ∠ XOA by Fig. 1), at starting point place, the volume in I district is minimum, and the volume in II district, III district is between maximum, minimum.
The process that middle shaft rotation angle is 0 ° ~ 270 ° is intake process, in this course, slide plate X end is lighted from A and is slided to B, C, D point successively, I district volume constantly increases, low-pressure gas flows into I district by valve 4, when axis rotates to 270 °, X end arrives D point, I district volume reaches maximum (in Fig. 1, working area maximum volume be slide plate vertical time inner walls arc BCD and the region that surrounds of axis and slide plate three), the gas process entered of I district its volume reach maximum near phase place complete (working area leave the scope of valve 4 after intake process terminate).Afterwards, along with axis continues to rotate, I district volume starts to diminish, in the angle of rotation of axis relative starting position in the process of 270 ~ 540 °, slide plate X end is lighted from D and is slided to A, B, C point successively, I district volume constantly reduces, and the gas in I district is compressed, and discharges (unlatching of valve 5 can adopt opened by pressure or cam trigger mechanism to open) after reaching certain pressure intensity (or feature phase place) from valve 5; When axis rotates to 540 °, X end arrives C point, and I district volume reduces to minimum, completes a working procedure.
The working principle of three working areas of this pneumatic element inside is identical, and be only that phase place is different, I district, II district, III district phase place differ 180 ° successively.
When needs are shut down, cut off driving force and close high voltage terminal valve 5.
3, this element is as specific works procedure declaration during pneumatic motor
In Fig. 1, when axis rotates in the counterclockwise direction, pneumatic motor work pressed by this element.
Below for III district, the concrete condition of this element by pneumatic motor work is described.For ease of explanation, the horizontal position of Y=A, X=C is arranged in for initial position (axis is rotated clockwise ∠ YOA and gets back to initial position by Fig. 1) with slide plate, at starting point place, the volume in III district is minimum, and the volume in I district, II district is between maximum, minimum.
In the process of middle shaft rotation angle 0 ° ~ 270 °, slide plate Y end slips over D, C, B point successively from A point, and III district volume constantly increases, and when axis angle of swing is 270 °, III district volume reaches maximum; Become in the certain phase range in large process at III district volume, pressurized gas flow into III district by valve 5, and (valve 5 can adopt cam trigger mechanism to open in feature phase place, or a direct-open), after air inlet terminates, along with III district volume becomes large further, pressurized gas expand in III district, and gas expansion process terminates when III district volume reaches maximum value.Afterwards, along with axis continues to rotate, III district volume starts to diminish, III district forwards the scope exposing valve 4 to and starts exhaust, and in the angle of rotation of axis relative starting position in the process of 270 ~ 540 °, slide plate Y holds to light from B and slides to A, D, C point successively, when axis rotates to 540 °, Y end arrives C point, and III district volume reduces to minimum, and an operation cycle completes.
The working principle of three working areas of this pneumatic element inside is identical, and be only that phase place is different, III district, II district, I district phase place differ 180 ° successively.
When needs are shut down, close high voltage terminal valve 5, this element can stop outputting power realizing shutting down.
