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.

on and noise of pump, finding whether leakage between axis end and pump cover, checking the excessive jump and swing of V wheel that is called belt wheel past, but now defined as V wheel in GBT/10412�002 General V Wheel. Don’t use water and oil with water to debug or cleanse tank in case of the pump and components of fuel dispenser is rust. Meanwhile preventing freeze water affect the normal operation because of low temperature. Regularly inspect and cleanse strainer, especial after installation a pipeline. With the working time get long the waste in pipeline or tank decrease, the perio fuel dispenser d of checking and cleanse should considerably lengthen. But don’t exceed one month. The strength of V wheel should be appropriate because low strength result in no oil discharge out or inefficiency. High strength, in another case, would increase the axis loan of motor and pump, fasting bearing abrasion of motor, pump and oil seal. Don’t adjust overflow valve to tight in case of increasing pump pressure so as to flux passing overflow valve, and well as noise, vibration and abrasion. Judgment for common failures Firstly, some failure analysis and correct judgment is necessary before maintenance. The principle of first analysis then disassemble, easy first is the basis to judge trouble. The common failure phenomenon of vane pump is that no delivery, inefficient flux, leakage, noise and abnormal vibration. They will be introduced one by one. No delivery or inefficient flux Apart from pump failure other component and pipeline trouble may also result in this phenomenon. Here only introduce pump failure and inspection method. Exterior inspection: to check motor that maybe d fuel dispenser on’t work, or rotate in opposite direction, or lose V wheel. Reversal result from wrongly connecting two phase wire in motor or power supply. Adjusting strength of V wheel or changing a new one deal with wheel slip. However, the reason that motor don’t work are several, either electric or mechanical failure. Disconn fuel dispenser ecting V wheel at first,

ext prototype. Stan Ovshinksy, who pioneered the NiMH battery, says he has now come up with a radical improvement on that technology that would be perfect for plug-in cars—if only his firm ECD Ovonics (partly controlled by Chevron, an oil giant) would let him go ahead. Yet the future may belong to lithium technology after all. One reason, says Menahem Anderman of Advanced Automotive Batteries, a consultancy, is that recent increases in the price of nickel and cobalt have limited the opportunity for further cost reduction of NiMH and made lithium batteries, which have traditionally bee fuel dispenser n far more expensive, more competitive. Alan Mumby of Johnson Controls, a big car-parts supplier, agrees. His firm has recently entered into a joint venture with Saft, a French battery giant, to produce lithium-ion batteries for hybrid cars. Mr Mumby maintains that “the lithium-ion battery both delivers and accepts power very readily, making it ideal for hybrids with regenerative braking. Lithium-ion technology is the wave of the future.�Lithium also has the crucial advantages of low size and weight. Hymotion s production-ready battery kits, due later this year, will feature lithium-ion batteries weighing just 70kg but delivering an all-electric range of 25-30 miles. Dead end or stepping-stone? Even if the battery woes that have long bedevilled electric cars can be solved, however, such progress may yet prove a stepping-stone to hydrogen—the bête noire of the electric-car crowd. “Long term, plug-ins with fuel cells may be the ideal vehicles,�says Mr Graham of the EPRI. Dr Frank agrees, noting that the hybridisation would mean cars would need less hydrogen on boa fuel dispenser rd, and smaller (and thus cheaper) fuel cells. Dr Ovshinsky even stood up after the New York premiere of “Who Killed the Electric Car?�to lecture the film s director and audience that batteries and hydrogen can work smoothly together.  The Prius hackers get to work Everyone is agr fuel dispenser eed on the need for
