【摘要】 通过改变齿高的方法来提高压缩比,提出了一种高低间断涡旋齿,建立了间断齿在气体压缩过程中的数学模型。间断涡旋齿的工作过程中包括了利用高低压气体混合来提高低压气体压力的步骤,包含了依靠高压气体的膨胀来压缩气体的思路。高低间断涡旋齿不但具有压缩比大、结构紧凑等优点,而且可将曲轴内嵌于动涡旋盘内,减小了动涡旋盘所受的倾覆力矩,因而具有较高的综合性能。更多还原

【Abstract】 In order to increase pressure ratio of scroll compressor through changing the wrap height,high-low discontinuous scroll wrap is proposed.The mathematical model of gas compression process of the proposed wraps is established.The working process of the discontinuous wraps comprises a peculiar procedure to increase pressure of low-pressure gases by mix between high and low pressure gases,which shows a new idea to compress gases by expansion of high-pressure gases. High-low discontinuous wraps not only have many advantages such as high pressure ratio,compact size,etc.,but also can be employed in conjunction with the configuration that crankshaft is embedded into orbiting scroll wrap,then the overturning moment acting on orbiting scroll is decreased.Therefore,the overall performance of scroll compressor is improved by applying the proposed wraps.更多还原
