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.

be installed in oil; in fuel dispenser 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, 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 call 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.

wing hourly output rising fuel dispenser at an annual rate of 3% . Start with GDP, which rose at an annual rate of 3.4%. For GDP per worker, deduct employment growth of 1.1%, from data for France, Germany and Spain, three of the top four economies in the club. Then adjust for hours per worker, which have been declining, largely because of the recent rise of part-time employment. Because firms are probably trying to get more hours out of the existing workforce before hiring new staff, Mr Chaney supposes a slower decline than in recent years 0.3%, against 0.9% in 2002 and 0.5% in 2004. For the whole year, Mr Chaney forecasts that output per hour will grow by 2.1%. Is this purely cyclical, or will some of the extra growth endure? “You can t say for sure,�he says, “but you get a feeling this is more than cyclical.�Above all, he thinks, European firms are beginning to reap the benefits from investing in information technology, something that America has exploited to far greater effect than Europe has (see article). Despite all this, euro-area optimists may face a testing few months. It is not hard to see demand growth being dragged down at the start of next year by a planned rise in value-added tax in Germany and budgetary tightening in Italy. That said, some other possible sources of trouble may be less threatening than they now seem. America s slowdown, though hardly welcome, is one such Europe s main source of pulling power these days is domestic demand. Oil prices may climb again, but the euro area weathered the recent spike fairly well and should get back a good slice of any extra it spends on energy imports. According to the commission s report, in 2000-05 oil exporters spent a bigger share of each extra dollar of export revenues on imports from the euro zone than they did in 1973-81. The euro area s exports to oil producers rose by 17% last year, adding 0.3% to GDP. The commission expects a further increase in 200 fuel dispenser 6.
