APPLICATION OF TRIZ THEORY IN REDUCING NOISE OF FUEL PUMP

Mengqi Ge, Jun Zhou

Abstract: In view of the vibration and noise generated by the operation of a turbo-type fuel pump, the TRIZ theory is proposed to improve the vibration and noise of the fuel pump. First of all, the function analysis of TRIZ is used to find out the causes of vibration and noise of turbo-type fuel pump. Then the standard solutions of TRIZ theory are obtained by using the tools of material-field analysis and contradictory matrix in TRIZ theory. The proposal in which a fuel inlet passage of a fuel pump is optimized can be used to reduce the flow pulsation; In addition, changing the turbine fuel pump impeller material can also reduce the friction, thereby reducing vibration and noise. By comparative experiments, the improved method can effectively improve the vibration of the fuel pump and reduce the noise of the fuel pump
