be installed in oil; in some regions and mount areas adopts high bracket tank, to refuel through oil gravity. Under these two situations the inlet oil pressure of fuel dispenser is larger than atmospheric pressure. The latter model adopts volume pump --- often gear pump or vane pump, installing inside of fuel dispenser together with motor. A certain vacuum pressure occurs at the inlet of fuel dispenser when fueling. Fuel dispenser mounted submersible pump, its pump being inside of tank with low noise, has large room to facilitate design many nozzles. The negative pressure fuel dispenser, however, has the benefit of convenient maintenance and low price of whole system. At recent, as negative pressure one prevails in market, fuel dispenser the article mainly introduce this kind of fuel dispenser. Negative pressure fuel dispenser normally selects a ration cubage pump. In order to ensure adjusting flow rate there is a bypass valve connected with pump in juxtaposition. When refueling fuel dispenser’s discharge capacity is controlled by the return volume of bypass valve that, of course, ensure the hydraulic system security of fuel dispenser. This kind of bypass valve generally is overflow valve that is closed down while fuel dispenser dot work, and always open as fuelling. The return volume of overflow valve is changed by fuel dispenser’s flowage. Pump is a key component. Its performance is measured through the following aspects: suction capacity, reliability, noise and stability. Of date, some manufacturer put pump and oil-air separator into a common frame, but some install these elements respectively. Some people in circle c fuel dispenser all pump and oil-air as pump source. Pump’s performance only relate to its structure design and manufacturing level, not the connection of components. The handbook, therefore, introduce by the category of pump, not by the connection of oil-air separator. Vance pump It is also called rolling broad pump.

s lower than the official productivity figures suggest, because productivity growth in farming and government, which are left out of those figures, is even lower. The longer the economy s expansion goes on, the slower productivity growth is bound to be. But the pace of the deceleration has begun to raise concerns. The small band of economists who study these things now agree that underlying productivity growth rose sharply in the late 1990s, from around 1.5% to some 2.8%. Three of those experts, Dale Jorgenson, of Harvard University, Kevin Stiroh, of the New York Fed and Mun Ho, also of Harvard, have calculated that over 60% of the late 1990s productivity surge was related to information technology. The industries t fuel dispenser hat saw the biggest productivity gains were those that used IT most intensively. The 2001-04 productivity surge is now the focus of an argument with big implications. Only 30% of that acceleration was related to IT, says Mr Jorgenson and his colleagues. Optimists take that as a good sign. It shows improvements in business processes spawned by the IT revolution are spreading through the broader economy. The economists reckon underlying business productivity growth is now around 2.5% (or around 2.2% in the overall economy). This is slower than in the late 1990s, but still far above historical averages. Others are more worried. Robert Gordon, of Northwestern University, reckons that the post-2001 acceleration was the result of cost-cutting, not innovation. Other economists note that the pace of investment, particularly in IT, is much lower than it was in the 1990s. JPMorgan s cal fuel dispenser culations, for instance, show that firms spending on IT equipment has grown by only 5.5% a year in this expansionary period, compared with over 20% a year in the late 1990s. Lower capital spending, they fear, could be a harbinger of slower productivity growth. Morgan Stanley s Mr Berner worries that high oil prices may also have hurt underlying productivity growth fuel dispenser , by shifting the relative profitabilit
