U702-A Submersible Pump

U702-A Submersible Pump

Until today, a large of fuel service stations in domestic use fuel dispenser located on the ground.The driven motor and pump are fixed in dispenser's enclosure. Depending on the negative pressure, the dispenser inject product into the tank of car. The problem is the vaporization of product when the head is over 4.27m. In contrast, the submersible turbine pump put in product directly, it drive product with the positive pressure from tank to dispenser on the ground. The total head can reach 30m without any vaporization, so the product tank can be installed more distance apart from station when design it. In addition, due to the pump is immersed in product, so the product is directly through motor bearings, cooling & lubricating them, whenever pump is operating. The wear is little and temperature rise is lower, with the results that the trouble decrease and service life is longer.The leaking of product and noise of operation are also very small,so the pollution for environment decrease.

Features:

3 stage turbine pumps are assembled to the spline of rotor shaft. The

stator is potted with epoxy sealing compound. When the motor is

started, then the bearings are lubricated by flowing product. Product

deliver to nozzle of oil gun through check valve and hose.

The electric control system used 220V power supply is simple, the

product pipe and power pipe in pump set are separated, so the

maintenance is easy.

There is manual pressure relief valve. It is easy to relieve the pressure in

the piping system during routine maintenance or troubleshooting and get

the product back to storage tank.

This avoid any pollution for envioronment as other pressure relief

method.

Simple servicing, the pump can be easily removed from the storage tank

by unthreading 3 bolts.

ury witnesses rapidly development of fuel dispenser and relevant system, such as various electronic display mode, presetting refueling devices, hanged fuel dispenser s fuel dispenser ystem without island fuel dispenser , submersible pump filling system, fuel dispenser mounted vapor recovery devices, multi-nozzles fuel dispenser, changeable oil label dispenser, and fuel dispenser installed IC card. (see Diagrams 1-4 to 1- 10).Meanwhile, some techniques correlative filling station management were developed consequently, including the Centre manager controlling multi-dispensers, monitor system for storage tank, station’s payment, safety alarm and services system, network transmission technique among relative departments, inter-station, and internal station, as well as customer self-operate refueling station system—no staff filling station. Diagram 1-2: Scale -counter fuel dispenser It is obvious that the technology of fuel dispenser is developed along with economic progress, characteristic of wide application of electronic technology. Diagram 1-3: Mechanical fuel dispenser (indicating volume, PPU and sales) China’s fuel dispenser technology develops very late, having not own petrol and automotive industry, low efficient transportation between rural and suburban. The first filling station was built in China until in 1924. Although a few cities have fuel dispensers imported from Western countries, their maintenance only being conducted domestically. In 1970s, these coastal cities such as Shanghai, Beijing, Tianjin, Qingdao, along with the restore and development of new China, the first fuel dispenser was manufactured in China. As the history of dependence upon foreign fuel dispenser came to halt, the development journey of China’s fuel dispenser technology starts its step. The fuel dispensers of Diagram 1-14 was regards as the representatives of China’s first generation fuel dispenser. Despite china’s fuel dispenser research and development it has disadvantage compared with developed countries. The mechanical counter fuel dis fuel dispenser

Plenty of suitors have appeared, but the banks are staying off the dance floor IT SEEMS an unlikely bastion of patriotism, but as most bits of British busine fuel dispenser ss fall to foreigner fuel dispenser s, banking remains stubbornly British. Nine of the country s top ten banks are British-owned. The exception, Abbey National, was bought in 2004 by Spain s Banco Santander Central Hispano only after years of mismanagement. But shareholders and foreign suitors are ever-hopeful that British domination of the country s banks will soon come to an end. On December 8th shares in Barclays surged to record levels after analysts at Morgan Stanley, an investment bank, said they thought Bank of America (BofA) was interested in buying it. Ken Lewis, BofA s chairman and chief executive, later said that he would “have to have a lot of uncertainties cleared up� before making an acquisition in Europe. But British banks appear to be in play. On December 11th Prudential, a British life insurer, said it had rebuffed a Citigroup bid for its internet- banking business, Egg. And it is not only American banks that are testing the water. In July Crédit Agricole said it had looked at buying Alliance & Leicester, a former building society, and Spain s Banco Bilbao Vizcaya Argentaria (BBVA) is thought to have pondered a bid for Lloyds TSB. The arguments for buying British banks look compelling. Britain s stable regulatory regime welcomes foreign ownership. For an American buyer, already constrained at home by rules preventing banks from making acquisitions if they have more than a tenth of national deposits, the common language and similar legal systems make Britain a good staging point for expansions into Europe. Santander s purchase of Britain s Abbey National also changed the landscape. Before that acquisition most banks had tended to focus on mergers in the same markets, where costs could be cut through closing branches. Santander, however, promised to trim almost a fifth of Abbey s costs by closing down its computer sys fuel dispenser
