    e, low cost and fuel dispenser convenient maintenance, vane pump is widely adopted in fuel dispenser many industrial areas. Most of domes fuel dispenser tic 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 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 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

    orgia can have fuel dispenser good relations with Russia “if we get down on our knee fuel dispenser s� But an actual war in Sou fuel dispenser th Ossetia or Abkhazia would mean disaster for Georgia, and not only because it would probably lose. It would make solving the territorial disputes impossible. And it would wreck one of Mr Saakashvili s dearest aspirations, and the one the Russians most resent his plan to take Georgia into NATO. All that should be clear, even to Georgia s young, hot-headed defence minister, Irakli Okruashvili. Mr Noghaideli says the whole government is committed to peaceable solutions. “There is a party of war,� says Mr Khaindrava, the sacked minister, “but it is in Russia.� Sabres are indeed rattling in Russia. The foreign minister, Sergei Lavrov, said recently that his country would use “all means�to protect its citizens in South Ossetia and Abkhazia. Thanks to Russia s generous ways with passports there, that applies to almost everyone in the statelets (though the Abkhaz, unlike the Ossetians, still covet full independence). During recent military exercises in the Russian north Caucasus, Russian officials made it clear that they had had Georgia in mind. On the other hand, Mr Saakashvili and his team are anxious to do something about the enclaves, which are being creepingly incorporated into Russia. That may be part of a Kremlin plan, also involving Moldova (see article). Much more waiting risks losing the territories for ever. Yet irresponsible talk and ill- considered actions will have unintended consequences. The lure of short, victorious wars Georgians are a proud, nationalistic lot, and virtually all of them share Mr Saakashvili s ambition to reunite the country. But 70 years of Soviet rule have also left them cynical, and some see another motive in the government s urgency over the enclaves to distract attention from its other travails. There have been big achievements, chief among them an impressive crackdown on corruption, which largely explain the president s st
