Description
Technical field
The utility model relates to a kind of modified model double rotor air compressor, belongs to the air compressor device field.
Background technique
Air compressor especially reciprocating-piston air compressor is used widely in various pneumatic equipments because of characteristics such as its pressure and range of flow are big, moderate, adaptability is strong.Rotary compressor is mainly used in air conditioner refrigerating, heats and dry industry.Existing rotary compressor generally adopts cam, slide plate or piston cylinder operator, comprise the housing that split is sealed and matched, suction port, air outlet are set on the housing, suction port goes out to arrange Aspirating valves, one-way valve is set on the air outlet, be slidingly matched in housing by cam, slide plate when rotated and realize the compression chamber volume-variation, thereby realize compression function.The machinery frictional ratio is bigger during the compressor operating of said structure, and parts wear and tear easily, influences using effect, and working efficiency is not high, and working environment is required height, and at suction port Aspirating valves is set, and gettering efficiency is not high.
The model utility content
At the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of modified model double rotor air compressor is provided, and the frictional force between the parts is little, long service life, and operating noise is little, and high working efficiency is processed easy to assembly.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of modified model double rotor air compressor, comprise compressor case and power mechanism, be provided with the compression chamber of two tubulars in its compressor case, be provided with air-flow path between two compression chambers; Be provided with rotor in described two compression chambers, rotor eccentricity is arranged in the compression chamber; Be with rotor shaft in the described rotor, rotor shaft is connected with power mechanism by gearbox.
Optimize, above-mentioned modified model double rotor air compressor, its rotor be provided with one cooperate with the compression chamber inwall increase compression ring.
Optimize, above-mentioned modified model double rotor air compressor, its gearbox is coaxial automatic directional driving mechanism.
Optimize, above-mentioned modified model double rotor air compressor, its power mechanism comprise a motor and are used for the control panel of control motor positive and inverse.
Optimize, above-mentioned modified model double rotor air compressor, its compressor case is provided with the single-phase suction valve of spring and unidirectional gas outlet valve.
Design has the compression ring that increases that cooperates with the compression chamber inwall on the utility model rotor, increases compression ring and cooperates with the rolling of shell inner cavity toroidal surface, has reduced the frictional force between the parts, has prolonged the working life of parts; And increase the compression ring motion steadily, rotating part is through mechanical efficiency height behind the balance check; Edge line speed is little, and noise is little, and static friction torque is little during startup, and it is little to start impact, and good startability is arranged, and energy consumption is low; Suction port is not owing to arrange Aspirating valves, and gettering efficiency height and operating noise are little, high working efficiency.
