Structural Design and Experimental Study of Duplex Fuel Pump

FENG Zhang-jun;RUAN-jian;Zhejiang Tongji Vocational College of Science and Technology;  
This paper introduces the structural characteristics of duplex fuel pump,and puts forward the double piston structure,which integrates the piston and the drive shaft,that is,the piston can change the volume of the cavity and transmit the power.And the working principle of the duplex fuel pump is described in detail.The flow characteristics of the prototype were tested,and the no-load and load flow characteristics curves and the flow rate curves under specific speed pressure were obtained.The volumetric efficiency of the duplex fuel pump is verified,and the volumetric efficiency curve is obtained under certain conditions.
