Abstract
The invention discloses a bidirectional sliding piece type fluid machine which comprises a machine shell, an eccentric rotor driven by a crankshaft and an inner shell. The machine shell, the eccentric rotor and the inner shell are sequentially arranged from outside to inside. An inner crescent space and an outer crescent space are formed by the inner surface of the eccentric rotor and the outer wall of the inner shell and between the outer surface of the eccentric rotor and the inner wall of the machine shell respectively. A supporting groove for installing sliding pieces is formed in the eccentric rotor, and the two ends of the sliding pieces are in close contact with the inner wall of the machine shell and the outer wall of the inner shell. The inner crescent space and the outer crescent space are divided into multiple sector inner and outer small chamber element volumes through the adjacent sliding pieces. According to the bidirectional sliding piece type fluid machine, by means of inner and outer bidirectional sliding of the sliding pieces, the top ends of the sliding pieces are not provided with back pressure cavities, the pressure of the sliding pieces and a cylinder body is reduced, stress is more even compared with that of sliding pieces of a traditional sliding piece type compressor, the service life is obviously prolonged, and noise and abrasion are reduced; and in addition, working cavities with volume changes exist inside and outside the eccentric rotor at the same time, so that stress of the eccentric rotor is more even, and the sliding piece type fluid machine runs stably and is small in vibration.
Description
Technical field
The invention belongs to field of power machinery technology, relate to a kind of two-way sliding vane fluid machinery.
Background technique
The equipment such as now widely used compressor, pump, decompressor have strict restriction in some applications to volume and weight, particularly use on the Mobile Equipments such as space flight, aviation, navigation and vehicle, not only require small in volume, and require high efficient and reliable;
By improving running speed, can reduce volume and weight, but its efficiency and reliability all decrease, this just requires that these equipment develop to small compact structure direction; Because these equipment of above reason are difficult to meet the use under specific condition, therefore the improvement of convection cell machinery is very important.
Summary of the invention
According to the deficiency that above-mentioned prior art exists, the object of the invention is to: a kind of simple and compact for structure, volume is less, efficiency is high two-way sliding vane fluid machinery is provided.
For achieving the above object, the technical solution used in the present invention is: comprise the engine housing set gradually from outside to inside, by eccentric rotor and the inner housing of crank-driven, eccentric rotor internal surface and inner housing outer wall, in eccentric rotor outer surface and casing inner wall are all formed, outer crescent-shaped space, eccentric rotor offers the support slot that several install slide plate, and slide plate two ends respectively with casing inner wall, inner housing outer wall close contact, when eccentric rotor rotates, slide plate two ends are close to casing inner wall, on inner housing outer wall, in, outer meniscate space by adjacent slide plate be divided into some fan-shaped in, outer cell element volume.
Described circumferentially evenly offers the support slot that four are installed slide plate on eccentric rotor, and slide plate can be free to slide vertically.
Described is all provided with frame inner-ring bearing and inner housing race bearing on engine housing inwall, inner housing outer wall.
Described casing and inner housing all offer air channel or water channel.
The present invention is by means of slide plate inside and outside Bidirectional slide in the support slot of eccentric rotor, back pressure cavity is not established in the top of slide plate, reduces the pressure of slide plate and cylinder body, stressed more even compared to traditional sliding-vane compressor slide plate, working life obviously increases, and reduces noise and wearing and tearing; And inside and outside eccentric rotor, have the active chamber of volume-variation simultaneously, make eccentric rotor stressed comparatively even, so this sliding vane fluid machinery running and comparing is steady, vibrate less; The inside and outside active chamber of two-way sliding vane fluid machinery rotor can be compression chamber or expansion chamber simultaneously, and also can be compression chamber, another side be expansion chamber.Its application area is promoted more, especially can apply with carbon dioxide refrigerating system; Because the slide plate of this two-way sliding vane fluid machinery is relative to inside and outside body, do not have radial play, inside and outside cylinder body can arrange bearing and reduce slide plate and cylinder body relative sliding velocity, reduces wearing and tearing further.
Further, the present invention is all provided with frame inner-ring bearing and inner housing race bearing on engine housing inwall, inner housing outer wall, reduces slide plate and cylinder body relative sliding velocity.
