Abstract

Split type turbocharger compressor volute, including contour body and runner body. The contour body is provided with a threaded hole and a conical hole for fixing the flow channel body, and the conical hole is provided with a first sealing groove and a second sealing groove. The flow channel body is provided with a pressure plate, a cone and a flow channel that match the conical hole on the contour body. The pressure plate is provided with a countersunk screw hole. The sealing groove matches the first sealing groove and the second sealing groove. During installation, the flow channel body is fastened in the contour body by the hexagon socket head bolt, and a diffuser groove is formed between the end surface of the pressure plate on the flow channel body and the body cavity of the contour body, and two O-rings are respectively installed on the first part of the contour body. In the first sealing groove and the second sealing groove and the first sealing groove and the second sealing groove on the flow channel body, two O-shaped sealing rings are used to seal the conical joint surface of the contour body and the flow channel body.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a turbocharger compressor volute. Background technique [0002] With the large-scale application of turbochargers in various fields at home and abroad, especially the large-scale promotion of vehicle engines, the engine displacement ranges from a few tenths of a liter to dozens of liters, and the design requirements and process requirements of various engine manufacturers The requirements of different conditions often lead to different design requirements for turbochargers, which also forces a dramatic increase in turbocharger models. [0003] Existing turbocharger compressor volute as attached Figure 7 As shown, the turbocharger compressor volute 7 is integrally formed by casting, and the turbocharger compressor volute 7 is provided with a flow channel 7-1 and a diffuser groove 7-2, and the diameter of the flow channel 7-1 is D1, the diameter of the diffuser groove 7-2 i...
