Description
Technical field
The utility model relates to the two moving scroll compressors of a kind of electromechanics, belongs to refrigeration scroll compressor technical field.
Background technique
Scroll compressor has two whirlpool dishes: a movable orbiting scroll and a quiet whirlpool dish.The movable orbiting scroll center moves in a circle around quiet whirlpool disk center under main shaft drives, this motion produces compression between two whirlpool dishes, low-pressure gas enters inhales the chamber, motion along with movable orbiting scroll, compression is a continuous process, a part of gas is compressed in second circular movement, and another part gas is just entering the whirlpool dish, and some gas is discharged from.The gas in this chamber reduces gradually, and when this chamber arrives center namely during relief opening, it is maximum that pressure reaches, and this has just passed through three complete circular movement, thereby realizes the purpose of compressor.
The scroll compressor volume is little, lightweight, and the eccentric shaft that drives moving turbine motion can High Rotation Speed.Because there is no Aspirating valves and outlet valve, the scroll compressor running is reliable, and easily realizes the variable speed motion and become the discharge capacity technology.A plurality of compression chambers are worked simultaneously, and the gas differential pressure between adjacent compression chamber is little, and quantity of gas leakage is few, and volumetric efficiency is high.Scroll compressor with its compact structure, energy-efficient, littlely shake low noise and functional reliability and be widely used in the industry such as industry, agricultural, communications and transportation, medical apparatus, food decoration and weaving and other needs compressed-air actuated occasions.
But existing scroll compressor can only lean on electric drive to work, if use on automobile, by the generator on car or storage battery power supply; It can not directly directly drive work by diesel engine, petrol engine or other dynamic power machines, and this has just affected the application area of scroll compressor.
If high capacity waggon uses electric scroll compressor, it often the phase carry out work by storage battery power supply, the burden of storage battery affects working life with regard to weight.If the scroll compressors that Organic Electricity is two moving, high capacity waggon in motion, the power of available motor directly drives dynamo-electric two moving scroll compressor work; When high capacity waggon stops timeout, can drive with the electric power of storage battery dynamo-electric two moving scroll compressor work, this can slow down the work load of storage battery greatly.
Summary of the invention
