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 fuel dispenser 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 fuel dispenser 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 fuel dispenser

, 15 months into his tenure as boss of Siemens, makes a good fist of selling his company as an “infrastructure supplier�well positioned to follow “megatrends�such as urbanisation and the growing demand for water, transport, health care, security and power. Yet he cannot disguise the fact that Siemens is for all that an unfashionable conglomerate that some analysts and investors would like to see streamlined further, or even broken up. Some Siemens divisions, such as power gene fuel dispenser ration, automotive parts and drives, or medical equipment, are world leaders. Others such as business services and communications are languishing. Reuters Kleinfeld tries to focus Siemens “How can one chief executive or one management team oversee all this?�asks Thomas Kitz, an analyst at Merck Finck & Co. Mr Kleinfeld showed his determination fuel dispenser to do just that last year by promising to bring the operating margins of each of Siemens 12 divisions up to a target figure by April 2007. At the halfway point he has already hit the target with six, three others are at least improving their performance and one division (logistics and assembly) has been phased out through integration. That leaves Siemens Business Services (SBS) and Com, which handles mobile and terrestrial communications networks, which are both in trouble. Com is around seven percentage points below its target margin, and SBS is losing money. Even if Mr Kleinfeld misses next year s targets, his job is unlikely to be on the line. Despite the impatience of some shareholders to see profits across all divisions—the last year that happened was 2000—there is a counter-argument in favour of some diversification. Siemens power generation and medical divisions, now success stories, were once problem children. Last week Siemens announced the purchase of Diagnostic Products Corporation in Los Angeles for around $1.86 billion (�.54 billio fuel dispenser
