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.

Diagram 2-7: Installation of framework oil seal Important notices to disassembly and reassembly As pump and motor are the resource of power one should pay much attention to disassembly and reassembly of pump. Be sure that cut power prior to maintenance. Disconnecting V belt in case to cause any accident, prepare a container to collect oil that will pollute environment. Grind the semicircle keyway on pump axis using sand paper before disconnecting pump cover in order not to scratch framework oil-seal by burr. All components should be carefully cleansed prior to reassembly of pump in case dirty substance flow into pump and cause new trouble. Turn rotor and examine the vane working state after installing rotor subassembly and spring in pump chamber. Meanwhile, be sure that the position of vane should higher than rotor, low pump frame even. A little grease should be daubed on the inner of brass bushing and f fuel dispenser ramework oil-seal when installing pump cover. When installing the bolts of pump cover each tension is coherent as the sequence that opposite bolts go first. After reassembly of pump to check inspect the rotation of pump. The seal ring between pump and vapor-recovery should be carefully examined before installing in case of leakage. Be sure that the two V wheels of motor and pump in line, having any obvious jump and wave. Internal gear pump Fuel dispenser is mounted now with two types of internal gear pump, namely, involute gear pump and inner cycloidal gear pump. In the former type a piece of crescent clapboard is installed between small gear and inner gear, dividing suction chamber with discharge chamber. However, in the latter type the division is realized through joint between gears, without clapboard. The smaller gear in internal gear pump is driver. Diagram 2-8 illustrate above gear pumps. Internal gear pump characterized that compact, light in weight, low noise and long service life still has disadvantage of complicated gear figure and high cost.

l, is favoured by business. Rather than policy nuances, the choice may be swayed by intricate calculations about São Paulo politics. Mr Serra has only been mayor for 14 months. He promised to serve a full four-year term. If he steps down, the PSDB would lose the city hall, since his deputy is from the Liberal Front, an allied but conservative party. The state governorship of São Paulo is Brazil s second most powerful elected job. But the PSDB lacks an obvious candidate to replace Mr Alckmin—apart, that is, from Mr Serra. On the other hand, were Mr Serra to lose again to Lula that might well finish his political career. So those arguments point to Mr Alckmin winning the presidential nomination. He is less well-known outside the state than Mr Serra, but the campaign might change that. Both men have carped about high interest rates, Mr Serra more vehemently, but neither is likely to abandon economic prudenc fuel dispenser e. That risk comes from Anthony Garotinho, a populist former governor of Rio de Janeiro whose wife now has the job. He is competing for the PMDB s presidential nomination against Germano Rigotto, the moderate governor of the southern state of Rio Grande do Sul. Whoever the PMDB names may not survive a convention in June. The party is a confederation of regional baronies. Its priority is to increase its current tally of nine state governorships. It may end up backing Lula. It is even less likely to field its own presidential candidate if the courts uphold a rule that bans parties from forming different alliances at national and state level. So the race may boil down to a contest between Lula and whoever the PSDB chooses. Lula is ahead, but his support is strongest in the poor north-east, “where the vote is more changeable,�says Gaudêncio Torquato, a political analyst. The opposition will remind voters that Lula s Workers Party is responsible for the worst corruption scandal in a dozen years. Mr Torquato predicts “a bloody struggle.� © 2006 .  fuel dispenser fuel dispenser
