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.

    As past over long service time, parts abrasion universally or cylinder severely damaged, a new measurement transducer should be installed to replace old one. As find exterior leakage, firstly inspect the bolts corresponding to leak section. Tightly screw loose bolts, if leakage is continued, disconnect and inspect the seal ring and gasket relative section. Substitute aging or damaged parts and reassemble. Apart from the above reasons of extensive colloid and surface abrasion, these trouble also cause abnormal operation of measurement transducer, such as position pin fall down from piston or deformation, small axis lost on upper and lower connecting rod, loose bolt between piston and connecting rod. The solution is that disassembling measurement transducer, replace damaged or unqualified components and reassemble. The products made in normal factory seldom appear these troubles. Since measurement transducer is core component of fuel dispenser, elaborate machining, disconnection and reassembly should be as careful as possible. All elements should be cleaned before reassembly, excluding water into inner. Bolts are tightened even and appropriately. Soft-piston measurement transducer As these merits --- small in size, light weight, beautiful appearance, high accuracy, piston exchangeable--- soft-piston measurement transducer is widely adapted in domestic fuel dispenser market. It generally involves two structures: four-piston structure and double-piston structure. The latter model is selected universally. Therefore, this article will introduce fuel dispenser the structure, working principal and maintenance of four- piston measurement transducer. Structure Diagram 2-20 and Diagram 2-21 show the cutaway view and exploded drawing of four-piston measurement transducer that is widely employed. The transducer mainly consists of sealed cover, upper subassembly, export axis, frame subassembly, piston subassembly, connecting rod and top cover, clearly presenting in Diagram 2-20 and Diagram 2-21.

    ts plans for airport growth do not take these desires into account. Even the Treasury is getting involved along with last week s budget it announced a consultation on carbon capture and storage, a subject far outside its traditional remit. This division of labour is generating plenty of paperwork, including a review of energy policy due this summer (a mere three years after the last one) and another on the likely cost of climate change to the British economy. Bombarded with information and advice from different sources at different moments, the government finds it hard to put forward clear and co-ordinated ideas. Even when policies are agreed, they can be thwarted by official timidity. Motoring is a good example. After increasing for years, petrol taxes have risen only once since 2000, when protests paralysed the country and gave the Tories a brief lead in the opinion polls. Driving in 2004 was 7% cheaper in real terms than in 1997, and few observers think that the modest tax hike imposed on dirty cars in last week s budget will do much to change matters. According to the Environmental Audit Committee, a parliamentary group, green taxes have fallen as a proportion of total tax revenue—from 9.8% in 1999 to 8.3% in 2004—even as emissions have risen. The review on climate change suffers from exactly these problems. Beverley Darkin, a researcher at Chatham House, a think-tank, notes that many of the measures are aimed at raising awareness rather than providing incentives to change behaviour. And most are micro £20m ($35m) to advert fuel dispenser ise energy efficiency, £50m for small- scale power generation. Some are reheated policies that have already been announced (a pledge that 5% of transport fuel should come from renewable sources by 2010) and plenty are just promises to investigate various schemes. There is little in the way of concrete, radical policy. In the end, the problem is that climate change is not yet a vote-winner.
