Problems solved by technology

At present, the oil sealing parts on the turbocharger generally use two sets of circular and elastic sealing rings, but the cutout of the sealing ring is linear. In actual use, the turbocharger working under high-speed and high-temperature conditions For compressors, the air passage and the lubricating oil passage are very close, it is inevitable that the oil will seep into the air passage through the sealing ring, causing oil leakage. Compressor, oil leakage is more serious and more common, which has affected its reliability

Embodiment Construction

[0014] A process for processing a new structure sealing ring of a turbocharger, comprising the following steps: material collection→cutting→flaring→heat treatment→grinding→closing→wall grinding→acceptance.

[0015] The steps of material collection include: selecting a stainless steel pipe or ductile iron pipe with an outer diameter of φ19 and an inner diameter of φ15.94 (if the size is wrong, the inner and outer diameter should be processed first), and cutting it into a ring with a width of 2.4mm.

[0016] The cutting steps include: using φ0.1 molybdenum wire to make a cutting frame, using a clamp to clamp the ring, and cutting one of its outer end faces. When cutting, the ring is parallel to the molybdenum wire, slowly approaching, and then wrapping around the ring. The axis rotates slowly; if the molybdenum wire needs to be lengthened, the ring can be tilted 10°; for the ring that needs to be cut obliquely, it can be rotated while moving forward to form a helix.

Abstract

The invention relates to the technical field of turbochargers, in particular to a process for machining a seal ring, which has a new structure, of a turbocharger. The process comprises the following steps of: selecting materials, cutting, flaring, performing heat treatment, grinding, closing, grinding a wall and performing acceptance check. Lubricating oil can be prevented from seeping effectively by using an L-shaped sealing ring or an inclined cutting seal ring which is machined by the process, so that a good leakage-proof effect is achieved, the problem of the oil leakage of the turbocharger is solved basically, and the reliability of the performance of the turbocharger is improved greatly.

Description

technical field [0001] The invention relates to the technical field of turbochargers, in particular to a process for processing a new structure sealing ring of a turbocharger. Background technique [0002] Turbocharger technology is one of the most revolutionary milestones in the development of internal combustion engines. In order to improve the power of internal combustion engines for automobiles, reduce fuel consumption, and reduce the emission of harmful gases, the use of turbocharger solutions has been recognized as an effective measure. At present, the oil sealing parts on the turbocharger generally use two sets of circular and elastic sealing rings, but the cutout of the sealing ring is linear. In actual use, the turbocharger working under high-speed and high-temperature conditions For compressors, the air passage and the lubricating oil passage are very close, it is inevitable that the oil will seep into the air passage through the sealing ring, causing oil leakage. ...
