Detection apparatus for can judge volute runner negotiability

The utility model relates to a detection apparatus for can judge volute runner negotiability, turbo charger be utilize engine institute combustion gas promote the volute in the turbine rotate, drive the impeller acting of calming the anger, the rotational speed of volute runner negotiability direct influence turbine, volute its inside volute runner in the casting very easily have residual such aspsammitolite and influence the negotiability, lack the effective method of a detection always. This device is that runner inlet flange inputs the ability that compressed air promoted the turbine fromthe upright wall that admits air when adopting simulation volute operating condition, according to the gaseous turbine pivoted revolution that promotes of certain pressure, sets for a revolution lowerlimit and is the acceptance value, realizes the detection of negotiability to the volute through instrument such as inductor counters. 本实用新型是种能判断涡壳流道流通能力的检测装置，涡轮增压器是利用发动机所排出的废气推动涡壳内涡轮转动，带动压气叶轮做功的，涡壳流道流通能力直接影响涡轮的转速，涡壳在铸造中其内部涡形流
