Abstract
The utility model relates to a single air sucking structure for a double-cylinder rolling rotor compressor for cooling, which mainly comprises an upper and a lower cylinders, wherein the two cylinders are separated by a middle separator plate. The utility model is characterized in that the two cylinders share one air inlet pipe; one of the cylinders is externally connected with an air inlet pipe, one path of the air inlet pipe is communicated with the cylinder by an air inlet of the cylinder, the other branch path is communicated with an air inlet of the other cylinder by a channel on the middle separator plate and an inlet end on the outer side of the air inlet is sealed by a sealing part. Compared with an original double air sucking structure, as having the single air sucking structure, the utility model has the advantages of small vibration, low noise, convenient field technology and high reliability; mass production can be carried out by using the existing production technology and the production line.
Description
Technical field
The utility model relates to a kind of refrigeration compressor, specifically refers to air-conditioning, refrigerator are used the improvement of the air suction structure of twin-tub compressor with rolling rotor.
Background technique
The present twin-tub compressor with rolling rotor that uses, by the intakeport air inlet, this double suction gas structural vibrations and noise are bigger, and the performance of compressor is affected respectively for general upper and lower cylinder.
Summary of the invention
The purpose of this utility model is to propose a kind of depressed structure of single suction of twin-tub compressor with rolling rotor, and with the technology of solution single suction gas and the contradiction of design, and this vibration of compressor is little, noise is low, has high reliability.
The depressed structure of the single suction of a kind of twin-tub compressor with rolling rotor of the present utility model mainly comprises upper and lower two cylinders, is separated by intermediate clapboard between two cylinders, it is characterized in that the shared suction tude of described two cylinders; The external suction tude of one of them cylinder, this suction tude are leaded up to the suction port of cylinder and are communicated with this cylinder, and other has one to communicate with the suction port of another cylinder by the passage on the intermediate clapboard along separate routes, and the outside entry end of this suction port is sealed by Sealing.
Advantage of the present utility model is: (1) the utility model adopts the structure of single suction gas, and depressed structure with original double suction is compared, and has the advantage that vibration is little, noise is low.(2) the utility model adopts the depressed structure of illustrated single suction, and on-the-spot technology is easy, good reliability; Can utilize existing production technology and production line to produce in enormous quantities.
Description of drawings
Now the utility model is described in further detail in conjunction with an embodiment and accompanying drawing thereof.
Fig. 1 is the sectional structure chart of an embodiment's of the present utility model single suction gas duplex cylinder compressor.
Among the figure: suction port on 10, suction tude on 11,12 intermediate clapboard passages, 13 times suction ports, 20 upper cylinders, 21 intermediate clapboards, 22 lower cylinders, 23 times cylinder caps, 25 upper cylinder covers, 26 blades, 28 eccentric shafts, 29 pistons, 30 housings, 31 outlet pipes, 32 motor stators, 33 rotors, 34 Sealings.
Embodiment
Fig. 1 is an embodiment of the present utility model, illustrates the longitudinal sectional view of a single suction gas twin-tub compressor with rolling rotor.Among the figure, after low-pressure gas was entered by the suction tude 11 of upper cylinder, a part entered upper cylinder 20 by last suction port 10, and another part is by the passage 12 on the intermediate clapboard 21, enter lower cylinder 22 by following suction port 13,14 of the outer entry ends of suction port 13 are by Sealing 34 sealings.Gas drains in the internal volume of housing 30 through after the Piston Compression in cylinder, and discharges compressor by outlet pipe 31.
The air intake passage 13 of described lower cylinder 22 at first is processed to a through hole, and then at outer entry end 14 place's indentation sealing spares 34 of this through hole, can not enter in the cylinder with the pressurized gas of guaranteeing housing 30 inner chambers.
