Description
技术领域technical field
本发明涉及的是一种涡轮增压器，具体地说是涡轮增压器的压气机。The invention relates to a turbocharger, in particular to a compressor of the turbocharger.
背景技术Background technique
离心压气机使用引气再循环装置广泛应用于国内外先进的涡轮增压器中的高压比离心压气机上，它的主要作用在于拓宽离心压气机的工作范围和扩大其喘振裕度。随着离心压气机转速和压比的提高，其有效的工作范围急剧变窄，采用其引气再循环装置以后，在离心压气机流量接近喘振边界时部分气体通过抽气槽抽气，再从回流孔流入，以使离心压气机的工作范围变宽，喘振裕度增大。Centrifugal compressors use bleed air recirculation devices that are widely used in high-pressure ratio centrifugal compressors in advanced turbochargers at home and abroad. Its main function is to broaden the working range of centrifugal compressors and expand their surge margins. As the rotational speed and pressure ratio of the centrifugal compressor increase, its effective working range narrows sharply. After adopting the bleed air recirculation device, when the flow rate of the centrifugal compressor is close to the surge boundary, part of the gas is pumped through the suction groove, and then Inflow from the return hole to widen the working range of the centrifugal compressor and increase the surge margin.
引气再循环装置抽气槽的位置和大小对其工作范围的拓宽和喘振裕度的增加有决定性的影响，不同的抽气槽位置对于不同转速下的离心压气机工作范围的扩大有不同的影响，传统的引气再循环装置往往不能同时大幅度的扩宽低压比和高压比时离心压气机的工作范围。The position and size of the air extraction groove of the bleed air recirculation device have a decisive influence on the expansion of its working range and the increase of the surge margin. Different air extraction groove positions have different effects on the expansion of the working range of centrifugal compressors at different speeds. The traditional bleed air recirculation device often cannot greatly widen the working range of the centrifugal compressor at the low pressure ratio and high pressure ratio at the same time.
