l gear pump Trouble and Maintenance The mainly troubleshooting and failure about pump presents in Table 2-1. Ta fuel dispenser ble 2-1 Troubleshooting Serial No. Failure Failure reasons Solutions 1 No de fuel dispenser livery o fuel dispenser r 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 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

She was lamenting the shifting horizons of those she represents who “keep falling in love with each other and then hating each other.� Prophetic enough. The next day Germany s Deutsche Börse withdrew its (repeatedly snubbed) offer to merge with the pan-European Euronext, clearing one obstacle to Euronext s proposed union with the New York Stock Exchange (NYSE). The same day a group of big investment banks fired its latest broadside in the war over trading fees by announcing plans to sidestep the exchanges with their own platform spanning Europe. The goal, the banks say, is to inject more competition into share trading and ultimately to lower costs, which can be up to eight times higher than in America. Hardly a week goes by without news of more upheaval in Europe s trading dens. The pressure for change is coming from two powerful forces regulators and customers. Similar forces have already pushed America s exchanges to cut trading fees and invest in new technology. On both sides of the Atlantic exchanges have sought to protect their heritage with plans to join forces, which would enable them to share trading systems and provide deeper pools of liquidity to their customers. Recently they have also begun to think globally.
