Online detecting device and method for turbocharger

Abstract

The invention discloses an online detecting device for a turbocharger. The device comprises a bearing lubrication system, a compressor end test system, a turbine end test system, a vibrating sensor (207) which is in contact with a casing of the turbocharger, a noise sensor (310) which is close to a turbine end of the turbocharger and a velocity sensor (105) which is close to an impeller of a compressor end of the turbocharger. The invention also discloses a method for using the online detecting device for the turbocharger to perform online detection on the turbocharger. The method can be used for detecting whether the flow of lubricating oil, the temperature of the lubricating oil, the pressure of the lubricating oil, the starting torque, the turbine end air outlet, the turbine end air inlet, the compressor end air outlet, the compressor end air inlet, the vibration and the noise are qualified or not. According to the online detecting device and the method, the consumed detection time is short, the cleanliness of the inside of the turbocharger is not influenced, and each turbocharger can be detected to guarantee that each turbocharger leaving the factory is qualified.

Description

technical field [0001] The invention relates to an online detection device and method for a turbocharger. Background technique [0002] A turbocharger generally includes a turbine end, a compressor end, and an intermediate body. The turbine at the turbine end and the impeller at the compressor end are connected by a rotating shaft to realize synchronous rotation. The rotating shaft is installed on a floating bearing. Push the turbine to rotate, the turbine drives the impeller to rotate through the shaft, and the rotation of the impeller will press the air sent by the air filter pipe, so that the air is compressed and enters the cylinder. [0003] At present, the performance test of the turbocharger after production is generally carried out by random inspection, and the test bench generally uses the combustion chamber to heat the compressed air and send it to the turbine end of the turbocharger to simulate the working condition of the turbocharger. The performance test of th...

Problems solved by technology

[0003] At present, the performance test of the turbocharger after production is generally carried out by random inspection, and the test bench generally uses the combustion chamber to heat the compressed air and send it to the turbine end of the turbocharger to simulate the working condition of the turbocharger. The performance test of the turbocharger using this kind of test bench is a full working condition test, which takes a long time, generally takes 3 to 5 hours, and the turbocharger after the test is fed with the compressed air heated by combustion. The internal cleanliness of the turbocharger is affected and cannot be sold, and random inspection cannot guarantee that every turbocharger that leaves the factory is qualified
