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.

    spenser because of stable operation, high anti-interference, high accuracy, long service life and wide scope of temperature adaptability, etc. Although clearance exist between piston and bushing, the leakage is very less, even no leakage. If the whole hydraulic system, including measurement transducer, work stably, with small pressure fluctuation, the leakage between piston and bushing too small to calculate when light loan. At present, the accuracy and reliability of metal-piston measurement transducer made by some domestic manufacturers are able to compare with that of famous export brand. The leakage change is still little under the various temperatures because of low expansibility of metal piston. Therefore, it is able to keep high accuracy even in wide scope of temperature change, which is outstanding merit.

    ion, train pilots and then lease the planes to the Royal Air Force whenever it needs to top up the fuel tanks of its jet fighters and bombers (usually on their way to the front line). When not needed by the military, some of the planes and aircrews will be rented out like U-haul trucks. Are PFI deals the best way to finance such commitments? Many suspect that they are little more than a wheeze to get borrowing off the public balance sheet, allowing the government to spend without (officially) exceeding its public-borrowing targets. The Treasury says they are used only when they provide better value for money than old- style procurement. The evidence is mixed. PFI contracts have a couple of advantages. First, they compel the contractor to finish on time by tying payments to the provision of service. The incentive seems to work. A 2003 National Audit Office (NAO) study found that 76% of PFI deals delivered projects on time, compared with just 30% of traditional procurements. The second is that they encourage contractors to consider running costs from the beginning because maintenance is included in their initial contracts. This should lead to buildings that are designed to be cheaper and easier to run. And finally, they limit the government s own flexibility to cut corners. Because maintenance is included in the contract, ministers are unable to dodge repairs when money is tight. But PFI contracts deliver these benefits at a cost. Private borrowers pay more for money than the government does. Then, too, the state m fuel dispenser ust transfer some risk (for example, that a building will take longer to build than expected) if it is to gain the benefits of private-sector expertise, but that adds to the cost. Better procurement and project management is meant to offset these extra costs, but the evidence that they do remains equivocal. Fans claim that the growing secondary market for PFI contracts, by broadening demand for them, will help narrow the gap between the government s own borrowing costs and the fuel dispenser fuel dispenser
