Turbocharger actuator calibration detection structure

Abstract

The invention relates to a turbocharger actuator calibration detection structure which comprises a turbocharger complete machine, a valve is installed in an air channel of the turbocharger complete machine, the opening amplitude of the valve is controlled by a valve rod, one end of the valve rod is connected with the upper portion of a transmission plate, and a transmission pin is installed on thelower portion of the transmission plate. The turbine comprises a pressing shell, a tail gas outlet is formed in the pressing shell and connected with a bypass valve gas pipe, the bypass valve gas pipe is of a three-way structure, the gas inlet end of the bypass valve gas pipe is connected with the tail gas outlet, the first gas outlet end of the bypass valve gas pipe is connected with gas pressure physical detection equipment, and the second gas outlet end of the bypass valve gas pipe is connected with the gas input end of gas pressure electronic detection equipment. The gas output end of thegas pressure electronic detection device is connected with the input end of the bypass valve, and the outer side of the pull rod is connected with one end of the adjusting sleeve. The turbocharger actuator calibration detection structure is simple in structure and small in occupied space; the calibration of the equipment detection pressure electronic device adopts a correction method compared with an atmospheric pressure mercury column, so that the pressure instability or the pressure instrument failure can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of turbocharger complete machine testing, and relates to a calibration detection structure of a turbocharger actuator. Background technique [0002] In order to ensure that the opening pressure of the bypass valve of the turbocharger reaches the set requirements when it leaves the factory, the displacement of the tie rod when the bypass valve is opened must be strictly controlled. In the existing detection process, the correctness of the input value of the detection air source cannot be guaranteed. , causing the test to fail. Contents of the invention [0003] The purpose of the present invention is to provide a turbocharger actuator calibration detection structure, which can solve the above problems. [0004] According to the technical solution provided by the present invention: a turbocharger actuator calibration detection structure, including a turbocharger complete machine, a valve is installed in the...
