e, fuel dispenser 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 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, fuel dispenser 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 fuel dispenser

he fuel dispenser chips are down Intel said it was cutting 10% of its workforce, or 10,500 jobs, to reduce costs and boost profit, which is being squeezed by intense competition from Advanced Micro Devices. Investors, hoping for more savings, were unimpressed with the chipmaker s plans. Sony announced another embarrassing delay to the launch of its PlayStation 3 games consoles in Europe. Further problems related to the integration of new Blu-ray technology mean the device will not now be available in the region until March 2007. Universal Music, a unit of the media conglomerate Vivendi, won the bidding to buy Bertelsmann s BMG Music Publishing, for which it will pay euro1.6 billion ($2.1 billion). The deal vaults Universal ahead of EMI and Warner Music in the lucrative business of licensing song lyrics and tunes to enterprises for uses ranging from television shows to ringtones. Russian authorities exerted more pressure on a liquefied-natural-gas project led by Royal Dutch Shell through a legal challenge to its construction on environmental grounds. The action should help the efforts of Gazprom, Russia s gas monopoly, to gain leverage over the $20 billion venture on Sakhalin island. The Compagnie Générale de Géophysique, a French energy-field surveyor, said it was buying Ver fuel dispenser itas, a Texan rival, for $3.1 billion. The deal underscores increased demand for seismic-equipment services linked to the hunt for new energy reserves. Meanwhile, Chevron, in alliance with two partners, revealed it had successfully completed a deep-water oil-production test in the Gulf of Mexico (breaking several records in the process). Some think that yields from recent discoveries in the Gulf may eventually rival those at Alaska s Prudhoe Bay, America s biggest field.
