FUEL DISPENSER & SPARE PARTS

FUEL DISPENSER & SPARE PARTS

Fuel dispenser are used in petroleum-retail service stations for filling lightweight oil including gasoline or diesel etc. We have taken up the production of fuel dispenser since1992. Among our gigantic business portfolio, oil transfer pumps were first put on our agenda and then mechanical fuel dispensers, electronic fuel dispenser in subsequence.

Our fuel dispensers have 3 series, namely, C series, D series and S series. All of the series share the same electronic system, which consists of flow meter, combination pump, auto nozzle etc. But C series is little in size and has a general outline with hoses from the middle. And D series contains jambs with stainless steel and hoses from the top. Then S series have a novel streamline outline and hoses from the top, which is bigger in size in comparison with the other ones.

ds of gear pumps. The following introduce cycloidal gear pump: Diagram 2-8: Two kinds of internal gear pumps Gear pump structure fuel dispenser Diagram 2-9 is an exploded drawing for inner cycloidal gear pump. Inner cycloidal gear pump mainly composed of frame, gear fuel dispenser -group, overflow valve, strainer, pump cover subassembly, etc. pump chamber is cylinder-shape in which strainer is installed at inlet of oil. Overflow valve and pump is in parallel connection. Concentric installation is between pump chamber and exterior gear-group, between inner gear and principal axis. But inner gear and outer gear is assembled centrifugally. Principal axis drives gear-group rotate. Gear pump has two chambers --- pressure oil chamber that discharge oil and suction chamber that suck oil—which are not connectable. When gear pump operating gear-group rotate anticlockwise at view of pump cover direction. Delivery pressure depends upon the adjustment of overflow valve, laden degree and inner penetration. In the process of nozzle open, small oil resistance, overflow valve is in low status of openness. However, as nozzle turn down or large oil resistance and pressure, the spring of overflow valve move sideward, increasing openness so that more oil flow into negative chamber. The outlet pressure of pump keeps under 0.3Mpa. Working principle of overflow valve The outlet of overflow valve is the interface in where pressured oil chamber pass into suction chamber. The overflow valve play role as a protection to restrict the highest pressure in hydraulic system and to adjust delivery volume of fuel dispenser. Its structure i fuel dispenser s illustrated in Diagram 2-9. Motor driving pump starting work, the pressured oil from pressure area flow into vapor-separator and overflow valve outlet via pump outlet. Given switch nozzle, part of oil flow out of pipe of vapor separator, another part of oil flow into suction chamber via overflow valve with small openness. However, as close down nozzle, pressured oil overcome spring bounce under high pressure in hydraulic s

ming problems. He thought his resignation would be seen as an admission of guilt and, seizing the moment, even tried to exploit the t fuel dispenser urmoil of recent days to install himself as the company s sole chief executive—his design for the past two years. But his fuel dispenser manoeuvres backfired. The board decided to maintain EADS s odd bicephalic structure and to keep Thomas Enders as its German co-chief executive. His new co-pilot is Louis Gallois, who was boss of SNCF, the French state-owned railway firm, for the past ten years. Before that, Mr Still under construction Gallois ran an aerospace firm that was merged into EADS in 1999. Mr Humbert was replaced by Christian Streiff, a former number two at Saint Gobain, a French glassmaker. Though both men are competent managers, they were also chosen because of their passports top jobs at EADS and Airbus are split between a German and a Frenchman to reflect the balance of power between the main shareholders. Analysts and investors doubt that the appointment of two new bosses will help solve the group s industrial troubles or ease the tension inherent in its dual management structure, however. The production problems remain a worry, too. On July 2nd Rothschild, an investment bank, valued the price at which BAE Systems, a British defence contractor, could sell its 20% stake in Airbus at �.75 billion ($3.5 billion), much lower than EADS or BAE had expected. BAE now plans to conduct a full audit of Airbus. It is anxious to get rid of its Airbus stake to boost its Ameri fuel dispenser can business, possibly even by merging with Boeing, which would love the increased exposure to the international defence market that BAE would provide. On Mr Gallois s first day in his new job, he and Mr Enders went to the Airbus factory in Toulouse to get a clearer idea of the problems with electrical wiring and customisation that have caused the delays to the A380 s delivery schedule.
