e, low cost and convenient maintenance, vane pump is widely adopted in many indu fuel dispenser strial 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 rese fuel dispenser arch 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, adjusting bolt and cap nut. The lower body is pump fuel dispenser 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

frain is identical “The market is depressed.�The reason? “Politics.� Sp fuel dispenser lit hairs, not atoms That partly reflects the fact that the economic liberalisation nudged forward by Muhammad Khatami, Mr Ahmadinejad s timidly liberalising predecessor, has been halted. But it also reflects rather grea fuel dispenser ter worries about the current crisis than the government admits to. Indeed, if European and other countries do join America s longstanding sanctions regime against Iran, it is far from clear that, in Mr Ahmadinejad s words, these countries “will be more hurt than us� Some of Mr Ahmadinejad s rivals certainly sound less sanguine. Akbar Hashemi Rafsanjani, a former president who lost to Mr Ahmadinejad in last year s election, recently predicted that the diversion of the nuclear programme from its “natural course� by which he meant the reference of Iran to the Security Council, would cause “lots of problems for us� Mr Rafsanjani also mentioned another embarrassment that Iranian officials rarely bring up these days Russia s foot-dragging in completing the nuclear reactor that it has built for Iran at Bushehr, on the Gulf coast; that was due to be finished several years ago. Mr Rafsanjani has long let it be known th fuel dispenser at he favours direct—though not necessarily declared� talks with America, aimed at settling all bilateral differences. The supreme leader s views, however, are less easy to read. Having said that Iran would respond to American aggression by striking at the United States interests “anywhere in the world� Mr Khamenei recently qualified that vow Iran would not initiate a confrontation. Mr Larijani, for his part, has repeatedly asserted that Iran is open to the idea of talks. On April 30th, he spoke of Iran s “readiness for agreement and accommodation� Over what? A history of Iranian overtures suggests that Iran would dangle concessions on its nuclear programme, its support for Arab groups that reject Israel s right to exist, and common interests
