l gear pump Trouble and Maintenance The mainly troubleshooting and failure about pump presents in Table 2-1. Table 2-1 Troubleshooting Serial No. Failure Failure reasons Solutions 1 No delivery or inefficient discharge Exterior elements: Motor stick; motor reversal; Sliding V belt; no oil in tank; pipe jammed; Check motor and its wiring; tighten V belt; inspect tank; dredge pipeline. Gear being stuck Clean waste in pump chamber Waste in outlet of overflow valve Disconnect overflow valve lid and clean waste; Leakage on valve Check oil groove Overweary gear or bearing Replace gears or bearing 2 Large noise or tremble Exterior reasons: Too long horizontal distance between fuel dispenser and tank; many elbow on inlet pipe; waste jam pipe; small diameter of pipe Dealt with in design and construction Intensive pressure Decrease thickness of pressured ring Overflow valve is stuck Clean waste and burr Overweary gear or bearing Replace gears or bearing 3 Inner leakage Overweary gears Replace gears Leakage on frame seal Frame seal disabled Replace frame seal Leakage on pump fuel dispenser body or joint face O-ring disabled Substitute seal ring 2.5 Important notices in operation Often inspect the rotation of pump axis, leakage, abnormal noise, vibration on V wheel and lose bolt that tight pump key. Regularly clean strainer. The tightness of V wheel should be appropriate, neither too tight nor too loose. These V wheels of motor, pump and adjusting driven wheel should be in parallel fuel dispenser level. Don’t adjusting overflow valve spring too tights in case that result in high pressure of hydraulic system, increase noise and vibration so as to enhance pump abrasion. Prohibit suck water or oil with much water. Strictly abide by the operation requirements on explosive atmosphere. Submersible pump In China filing stations recently begin to adopt submersible pump as the power resource of fuel dispenser. Submersible pump gen fuel dispenser

are the threats to energy security and what should the world do about them? The answers suggest a need for planning and a certain amount of grim realism, but not for outright panic. A classic tale The unhappy history of Ukraine, Russia and gas is the story of energy security in miniature. When it comes to hydrocarbons, geopolitics and geology are inextricable. That is a problem for most countries in eastern Europe, which would love to get their energy from allies, and feel understandably twitchy about having their former master as a big supplier. Russia sees it differently. It wants to use its energy riches to the maximum effect in the world market. It sees former communist satellite countries as nuisances, which scrounge subsidised gas, pay late if at all, and jeopardise sales to western Europe by brinkmanship about transit fees. It is easy to understand why Ukraine and other Russian neighbours are exasperating Gazprom, Russia s huge gas monopoly. Its gas has long been siphoned off in vast quantities and Ukraine, like Georgia, has a dreadful record of falling behind with its payments. The main power station that supplies Moldova doesn t pay its bills fuel dispenser at all. In 2005 Ukraine paid only $50 per 1,000 cubic metres of Russian gas, compared with the $240 paid by the EU. Now Gazprom says it wants to sell to these countries on a purely commercial basis. That seems fair enough, but there is another dimension. Formally, at least, the $50 price is part of a framework that is supposed to last until 2009. Moreover, Gazprom is not asking for the same increase from fuel dispenser each of Russia s neighbours. The independent Baltic states have two years to adjust. Georgia, which like Ukraine has an independent streak, faces a doubling of prices. Belarus, still friendly and dependable, is keeping its price and giving away part of the control of the pipeline to Russia instead. Gazprom and its chairman, Dmitry Medvedev, who moonlights as the head of Vladimir Putin s presidential administration, decided which deal is fuel dispenser
