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 i fuel dispenser s mounted in fuel di fuel dispenser spenser. 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 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, fuel dispenser 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 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

uals are taking on more financial responsibility, not least in providing for their old age. Maybe they should be better prepared WHEN IBM announced an overhaul of its pension plan for employees in America last week, it joined a para fuel dispenser de of employers tha fuel dispenser t are shifting more responsibility for saving for retirement on to workers. For many Americans, of course, this is nothing new millions of them have been managing their retirement assets in individual accounts for years (see chart 1). Nevertheless, in both America and Britain the closure of paternalistic corporate “defined benefit�?programmes, in which pensions depend on earnings and years of service, is accelerating—even at healthy companies such as IBM (see article). To the extent that this creates and encourages individual choice and responsibility, it is something to welcome rather than to fear. Many other countries, facing huge state-pension obligations, would also like to see their citizens assume a bigger role in providing for their own retirement. Even so, the trend raises an important question how much do people due to take on these new responsibilities know about basic financial concepts? The answer fuel dispenser seems to be not much, and less than they think they do. Studies show that many people overestimate their knowledge of everything from inflation to risk diversification and compound interest. One survey in Australia found that 37% of people who owned investments did not know that they could fluctuate in value. In America 31% did not know that the finance charge on a credit-card statement is what they pay to use credit. Britain s Financial Services Authority will release the results of its own survey on financial literacy in the next month or two. Even educated professionals may know the basics but see no need to keep up to date—having no idea of the interest rates on their credit cards, the fees on their mutual funds or how their investments are doing. But in both America and Britain low personal saving rates (negati
