e, low cost and convenient maintenance, vane pump is widely adopted in many industrial areas. Most of domestic manufacturer of fuel dispenser install vane pump as component. Vane pump includes ration pump and variable pump, the former is mounted in fuel dispenser. At recent years, the domestic noise research for vane pump has been achieved good progress conducted by fuel dispenser manufacturer. The noise of vane pump has fuel dispenser remarkably been downed, reaching to less than 70 d B. it is introduced as followed: 1: Cap nut 2: Adjusting bolt 3: Spring seat 4: Spring 5: Blade 6: Rotor 7: Plug 8: Spring flake 9: Axis 10: Frame 11: Overflow valve 12: Valve seat Diagram 2-1: Vane pump structure drawing Structure and working principle of vane pump The Diagram 2-1 and 2-2 illustrate one kind of vane pump about its structure and tridimensional exploded drawing. This kind of pump prevails in domestic fuel dispenser market. Its structure, principle and maintenance will be introduced. Vane pump consists of overflow valve and vane pump illustrated in Diagram 2-1. Overflow valve is installed on the upper of body, including overflow valve seat, vale core, spring, spring bracket, jointer, adjusting bolt and cap nut. The lower body is pump section composed of gliding bearing, rotor subassembly, blade set, spring flat and pump cover with gliding bearing. The right side of diagram is inlet, the fuel dispenser opposite outlet. The working principle, performance and common troubleshooting of vane pump and overflow valve will be presented respectively. Vane pump section The chamber in where rotor installed is pump chamber, its installing procedure showed in diagram 2-3. A centrifugal degree e between the center of chamber and rotor is illustrated in diagram. There are upper and down seal area, high pressure and low pressure transitional area, divided by the center of rotor. The angular degree in sealing area is larger than that of degree formed by the neared two vanes so as to prevent oil flow between low and high pressure areas. 1-Cap fuel dispenser
