Abstract
A novel rotor type compressing-expanding machine is formed by an air-suction pipe, a sliding slice, an air-exhausting valve, an air-exhausting pipe, a base, a compressing-expanding machine shell, a sliding slice spring, a shaft, a cylinder cover, an air cylinder and a rotor. Working principles include that the shaft drives the rotor to roll along the inner wall of the cylinder, and crescent-shaped space between the compressing air cylinder rotor and the air cylinder is separated into two parts. The volume of one part crescent-shaped space rotating along the rotor changes from small to large, and the crescent-shaped space sucks air; the volume of another part of the crescent-shaped space changes from large to small, and the crescent-shaped space compresses the air. In the expansion cylinder, the crescent-shaped space between the compressing air cylinder rotor and the air cylinder is separated into two parts of an expanding cavity and an air-exhausting cavity. High pressure air enters the expanding cavity through an expanding air channel under the control of an expanding control groove so that an expanding rotor is driven to act, and a compressing rotor is driven to compress the air with a motor.
Description
Technical field
The utility model belongs to refrigeration technology field.
Background technology
Now, refrigeration system is widely used in the every field of producing and living.But the restriction loss in the conventional refrigeration is larger; Only have the decompressor of employing to reclaim expansion work and could obtain higher cycle efficieny.For this reason, various compressing expansion machines have been researched and developed out, comprising the rotator type compressing expansion machine.But the rotator type compressing expansion machine also exists deficiency, and the slide plate of rotator type compressing expansion machine is cantilever support, and is stressed unreasonable; Yielding at high pressure, cause the Leakage Gas between slide plate, roller and the cylinder cap larger; Make refrigeration system be difficult to the efficient that reaches high.
Summary of the invention
The purpose of this utility model provides a kind of Novel rotor type compressing expansion machine, and the length of this machine slide plate is also opened radial slot greater than rotor length in the cylinder cap inboard, and the slide plate two ends place this groove; Making slide plate is two-side supporting, makes reasonable stress; And make the sealing between slide plate and the cylinder cap become side seal by end face, can reduce end wear and the Leakage Gas of slide plate and cylinder cap, obtain the higher cycle efficieny that gets.
Structure of the present utility model is by being comprised of slide plate, base, compression-expansion casing, sliding blade spring, axle, cylinder cap, compression cylinder, compression rotor, expansion rotor and expansion cylinder etc.; Wherein base and compression-expansion casing weld together, and consist of the space of sealing; Compression cylinder is identical with the expansion cylinder structure, is cylindrical shape; The air-breathing aperture that radially the offering of compression cylinder is not with inlet valve and with the vent ports of air bleeding valve; Expansion cylinder radially offer induction port and vent ports; Cylinder cap places the two ends of cylinder, consists of the volume of cylinder that seals with cylinder inner wall, rotor outer wall and slide plate; Rotor eccentricity is contained on the axle, and rotor rolls along cylinder inner wall, forms crescent-shaped space with cylinder; Be shaped with slideway on cylinder and the cylinder cap, slide plate is made the narrow spill in wide centre, two ends, places in the slideway on cylinder and the cylinder cap; Lean on the effect of spring to make its inner and rotor surface close contact by slide plate; Slide plate is reciprocating along slideway with the rotor rolling; Being shaped with oil duct on oil duct, the cylinder cap on the cylinder cap and on the axle communicates with slideway on the cylinder cap.
Operation principle: motor rotation, roll along cylinder inner wall by the axle rotor driven; Crescent-shaped space is divided into two parts by slide plate between compression cylinder internal rotor and cylinder.With the variation of rotor rotational angle, two-part volume changes thereupon; The volume of part crescent-shaped space changes from small to big and sucks gas, and the volume of another part crescent-shaped space is Compressed Gas from large to small.At expansion cylinder, crescent-shaped space is divided into expansion chamber and discharge chamber two parts by slide plate between rotor and the cylinder; Gases at high pressure after cooling or moist steam enter expansion chamber through the expansion air flue under the control of the expansion control flume that axle is opened, promote the expansion rotor, the acting of expanding; Promote the compression rotor Compressed Gas with motor.When slide plate was reciprocating along slideway, lubricating oil entered the cylinder cap slideway by the oil duct on the axle, and the compensation slide plate plays antifriction and sealing function at the contact-making surface of the also lubricated rotor in the space that the cylinder cap slideway stays and cylinder cap.
Because the length of this machine slide plate is opened radial slot greater than roller length in the cylinder cap inboard, the slide plate two ends place groove; Making slide plate is two-side supporting, makes reasonable stress; And make the sealing between slide plate and the cylinder cap become side seal by end face, can reduce end wear and the Leakage Gas of slide plate and cylinder cap, can obtain better lubricated between rotor and the cylinder cap; The leakage of gas is few, has than the higher efficient of common rotor compression decompressor.
