Abstract

Grooved sections (141-1) are arranged in such a way that the upper impeller and impeller The bottom slides in the outer perimeter of the center divider plate (140-1) in the rotary press. Double the amount of misalignment in the upper eccentric section and the lower eccentric section. of the rotating shaft is 30% or more of the total length in the sliding direction of the upper impeller and bottom impeller, respectively, width W of the grooved part (141-1) in the circumferential direction of the plate The center divider (140-1) will be greater than the thickness T of each of the top and bottom vanes when the depth of the grooved portion (141-1) is D and the total length of each one. of the upper impeller and lower impeller is L, D greater than or equal to 0.1 X L ... Expression 1 will be satisfied.

Claims (7)

1. The rotary compressor consists of: a vertical cylindrical compressor body in which the upper part is provided with sections. emissions for refrigerant And in the bottom part will be provided with a suction part. for refrigerants; The compression unit is arranged in the bottom section in the compressor body, which compresses the refrigerant that is suction from the suction section and that generates its discharge from the discharge portion; and a motor arranged in the upper section in the compressor hull and drives the compression unit, where the compression unit consists of a ring-shaped upper cylinder and a lower cylinder. ring shape, upper barb end plate on top of cylinder, lower end plate with Upper baffle of lower cylinder, middle baffle arranged between upper cylinder and cylinder below and the bottom block of the upper cylinder and the top of the lower cylinder, the rotating shaft driven by the motor, the upper eccentric section and the eccentric section. The bottom is provided with a rotating shaft with a phase difference. 180°C, top mounted piston In combination with the upper eccentric section, orbiting along the inner surface of the upper cylinder and forming the upper cylinder chamber in the upper cylinder, the lower piston is assembled. to the lower eccentric part, which performs an orbital motion along the inner perimeter surface of the bottom cylinder and that creates a bottom cylinder chamber in the bottom cylinder, the top impeller that separates the chambers. The upper cylinder is detached from the upper suction chamber and the upper compression chamber, which are protruded from the impeller groove. The upper cylinder provided in the upper cylinder goes to the upper cylinder chamber and comes into contact with the upper piston and the lower impeller separating the lower cylinder chamber into the lower intake and exhaust chambers. Bottom compression where it is projected from the bottom impeller groove provided in the bottom cylinder to the chamber. the bottom cylinder and come into contact with the bottom piston, the grooved portion is arranged in such a way that the top and bottom blades Slide in the outer periphery of the center baffle, twice the amount of eccentricity of the top eccentricity and eccentricity section. The bottom center of the rotating shaft is 30% or more of the total length in the propeller sliding direction. upper and lower blades respectively, and the width W of the grooved section in the circumferential direction of the center divider is greater than the thickness T of each one of the top impeller and bottom impeller. and when the depth of The grooved part is D, and the total length of each one of the upper and lower impellers is L, D greater than or equal to 0.1 X L ... The expression 1 will be satisfied. 2. Rotary compressor according to claim 1, where at the center of the lower end of the piston Top and bottom piston 80% or more of total length in impeller sliding direction The upper and lower impellers are respectively packed in the upper cylinder and the lower cylinder. 3. Rotary compressors according to claim 1, where a coating plate is provided at the leading end of the upper impeller in contact with the piston. Above, a coating plate is provided at the leading end of the impeller. of the bottom impeller which comes into contact with the bottom piston, and the coating consists of any combination of diamond carbon, chromium nitride and titanium nitride. 4. Rotary press according to claim 1, where grooved sections are formed from one end to another end of the plate. Divider in the middle in the direction of the axis of rotation. 5. Rotary press according to Claim 4, where grooved sections are created from one end to another end of the plate. Divides in the middle with uniform depth D. 6. Rotary compressor according to claim 1, where grooves are made in the The chamfered surface will be Formed at each one of the angles between the surface where the top blade slides in the median dividing plate and the surface. inside of the grooved part and the angle between the surfaces in which the lower impeller slides in the center dividing plate. and the inner surface of the grooved part 7. Rotary press according to claim 1, where the grooved portion is formed in such a way that the perimeter surface of the baffle is straight. The center is grooved in a curved shape in cross-section perpendicular to the axis of rotation.
