Description

Technical Field

[0001] This utility model relates to the field of turbocharger technology, and in particular to a fixed pipe connection structure for a turbocharger test bench. Background Technology

[0002] The turbocharger pressure test bench positioning pipe is a key component of the equipment used for turbocharger performance testing and experimentation. Its function is to connect the turbocharger to the test system, ensuring stable gas flow and accurate parameter measurement during the test.

[0003] Currently, the fixed pipes of the turbocharger pressure test bench are usually connected by flanges. However, after a long period of use, it is difficult to align the through holes of the flange fastening screws of the fixed pipes of the turbocharger pressure test bench with the through holes of the flange fastening screws of the fixed pipes of the test bench. This is especially true for general turbocharger test benches, where there are many specifications and models of turbochargers.

[0004] Frequent replacement of the fixed pipes on the test bench can easily lead to misalignment of the pipe flange fastening screw holes, resulting in the inability to connect the fixed pipes on the turbocharger pressure test bench to the main pipes. Summary of the Invention

[0005] The purpose of this utility model is to provide a connection structure for the fixed pipe of a turbocharger test bench, which solves the problem that the existing turbocharger test bench fixed pipe flange fastening screw through hole and the test bench fixed pipe flange fastening screw through hole will become misaligned after a long time, resulting in the turbocharger test bench fixed pipe and the test bench fixed pipe being unable to be connected.

[0006] To achieve the above objectives, this utility model provides a turbocharger test bench fixed pipe connection structure, including a turbocharger housing interface, a mating flange, multiple fastening screws, multiple fastening nuts, a connecting flange, and a test bench fixed pipe. The mating flange is fixedly connected to the turbocharger housing interface and is located on the side of the turbocharger housing interface. The multiple fastening screws are threadedly connected to the mating flange and are located on the side of the mating flange. The multiple fastening nuts are threadedly connected to the corresponding fastening screws and are located on the side of the corresponding fastening screws. The connecting flange is slidably connected to the multiple fastening screws. The multiple fastening screws pass through the connecting flange and are located on the side of the connecting flange. The test bench fixed pipe is rotatably connected to the connecting flange and is located on the side of the connecting flange.

[0007] The fixed pipeline connection structure of the turbocharger test bench also includes an O-ring seal. The housing O-ring seal is fixedly connected to the turbocharger housing interface and is located between the turbocharger housing interface and the mating flange.

[0008] The turbocharger test bench fixed pipe connection structure also includes a fixed pipe O-ring seal, which is fixedly connected to the test bench fixed pipe and located on the side of the test bench fixed pipe.

[0009] The turbocharger test bench fixed pipe connection structure also includes multiple anti-loosening gaskets, which are slidably connected to multiple fastening screws and located on the sides of the fastening screws.

[0010] This utility model discloses a fixed pipeline connection structure for a turbocharger test bench. A mating flange is fitted onto the side of the turbocharger housing interface and communicates with it, forming a sealing structure between the turbocharger housing interface and the mating flange. A connecting flange is fitted onto the fixed pipeline and can move freely in the circumferential direction of the fixed pipeline. The connecting flange has multiple through holes that match the fastening screws. During installation, the fixed pipeline is pressed tightly against the mating flange, and then the connecting flange is rotated so that the multiple fastening screws pass through it. Then, the fastening nut is screwed onto the fastening screws, bringing the fastening nut closer to the connecting flange, and pushing the connecting flange closer to the fixed pipeline. The pipeline secures the platform-fixed pipeline between the mating flange and the connecting flange, forming a sealed structure between them. At this point, the turbocharger housing interface is connected to the platform-fixed pipeline. This method avoids the problem of the through-hole on the connecting flange not aligning with the fastening screws when connecting the turbocharger housing interface and the platform-fixed pipeline. It facilitates the connection between the turbocharger housing interface and the platform-fixed pipeline and reduces the risk of cracking during turbocharger operation. It fully considers the working conditions during turbocharger testing and on the upper and lower test platforms, achieving practicality, safety, reliability, and convenience.
