l gear pump Trouble and Maintenance The mainly trou fuel dispenser bleshooting 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 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 adjus fuel dispenser ting driven wheel should be in parallel 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

their current-account deficits. Much of the selling h fuel dispenser as been indiscriminate, hitting the prudent and imprudent alike. Yet Turkey may become exposed the moment investors start to pick and choose. A $25 billion current-account deficit (see chart) and an inflation rate that unexpectedly rose to 8.8% in April, marks it out from accident-prone countries such as Brazil, whose company it used to keep. In May alone, the lira plunged by 17% against the dollar. Questions over the ability of Durmus Yilmaz, the new central-bank governor, to deal with the inflation did not help—he has set himself a year-end inflation target of 5%. Cabinet ministers stirred up further trouble by wading into the interest-rate debate, against the wishes of Mr Yilmaz. At least no one thinks Turkey is anywhere close to its precarious position in 2001, when the economy shrank by around 7% and the country flirted with debt default. Some Turks, including those in the street, think the fall in the lira may even prove to be a “long-overdue corrective�that will help exports, cut imports and so help plug the current-account deficit, according to Tanju Oguz, an Istanbul-based financial consultant. In a further boost, a Franco-Belgian bank, Dexia, announced this week that it was buying a 75 percent stake in Denizbank, Turkey s sixth-largest private bank, for $2.44 billion. If all goes according to plan, foreign-direct investment is set to exceed last year s record of $9.6 billion. But the International Monetary Fund, whose officials visited Turkey last mon fuel dispenser th to review a three-year $10 billion loan agreement, was critical just when markets were becoming more volatile. The IMF said the government needed to cut back spending by up to $3 billion to offset its current-account deficit, and adopt a cautious monetary policy. It told the government that it had to adhere strictly to its fiscal policies, and make no further cuts in value-added tax. The bigger worry among many foreign investors is the growing political instability fuel dispenser
