Air tightness detection device for turbocharger shell

The invention provides a turbocharger housing air tightness detection device, which comprises a rack, and an air tightness detection unit, a control unit and a marking unit arranged on the rack, the control unit comprises a controller, a display and an alarm device, and the air tightness detection unit comprises a plugging mechanism and a gas conveying mechanism. The plugging mechanism is used for plugging each cavity of the turbocharger shell into an independent space, and the gas conveying mechanism is used for inflating each cavity and monitoring the gas leakage rate after the turbocharger shell is plugged. According to the technical scheme provided by the invention, one-time detection can be carried out on the air tightness of each cavity of the turbocharger shell at the same time, and the efficiency of detecting the air tightness of the turbocharger shell is improved. 本发明提出了一种涡轮增压器壳体的气密性检测装置，包括机架和设于机架上气密性检测单元、控制单元和打标单元，所述控制单元包括控制器、显示器和警报器件，所述气密性检测单元包括封堵机构和气体输送机构，所述封堵机构用于将涡轮增压器壳体各腔室封堵为独立空间，所述气体输送机构用于在涡轮增压
