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 de fuel dispenser livery 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 fuel dispenser 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 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

n districts and leading critics of Syria, remain unresolved. The anti-Syrian coalition led by the prime minister, Fouad Siniora, and made up of Sunni Muslims, with some Christians and Druze, easi fuel dispenser ly won last year s elections. But Mr Siniora has struggled to bring in reforms. The continued hostility of Syria, whose territory surrounds most of Lebanon, has been one obstacle. Its president, Bashar Assad, has ignored Mr Siniora s repeated overtures, as well as a UN Security Council demand that Syria demarcate the border and extend normal diplomatic recognition. Mr Assad s prickliness has reinvigorated Syria s allies in Lebanon, and chilled the investment climate. Mr Siniora s reforms have also been hamstrung by the complex constitutional formula that was hashed out to end the civil war and which effectively grants veto power to his opponents. Most humiliating was a failed bid, in March, to unseat President Emile Lahoud, whose tenure was extended under Syrian pressure in the months before Hariri s death. Mr Siniora could not muster the needed majority of three- quarters of MPs, due to a controversial alliance forged by Hizbullah, which is backed by Syria and Iran, with Michel Aoun, a Christian general who foug fuel dispenser ht Syria during the civil war, was then exiled, and returned last year to head a populist, largely Christian party. It is widely seen as a vehicle for Mr Aoun s own ambitions for the presidency, a post that by Lebanese tradition is reserved for a Maronite Christian. Mr Siniora s opponents have blocked progress on a bigger issue too Hizbullah is the only Lebanese faction that has kept its weapons. Why? Some Lebanese agree that the Shia militia has earned the right, since it fought a guerrilla war that prompted Israel, six years ago, to end its two-decade-long occupation of south Lebanon. But most non-Shias mistrust Hizbullah, want state authority strengthened and fear provoking Israel. Besides, the UN Security Council has demanded specifically that all Lebanese factions disarm.
