on and noise of pump, finding whether leakage between axis end and pump cover, checking the excessive jump and swing of V wheel that is called belt wheel past, but now defined as V wheel in GBT/10412�002 General V Wheel. Don’t use water and oil with water to debug or cleanse tank in case of the pump and components of fuel dispenser is rust. Meanwhile preventing freeze water affect the normal operation because of low temperature. Regularly inspect and cleanse strainer, especial after installation a pipeline. With the working time get long the waste in pipeline or tank decrease, the period of checking and cleanse should considerably lengthen. But don’t exceed one month. The strength of V wheel should be appropriate because low strength result in no oil discharge out or inefficiency. High strength, in another case, would increase the axis loan of motor and pump, fasting bearing abrasion of motor, pump and oil seal. Don’t adjust overflow valve to tight in case of increasing pump pressure so as to flux passing overflow valve, and well as noise, vibration and abrasion. Judgment for common failures Firstly, some failure analysis and co fuel dispenser rrect judgment is necessary before maintenance. The principle of first analysis then disassemble, easy first is the basis to judge trouble. The common failure phenomenon of vane pump is that no delivery, inefficient flux, leakage, noise and fuel dispenser abnormal vibration. They will be introduced one by one. No fuel dispenser delivery or inefficient flux Apart from pump failure other component and pipeline trouble may also result in this phenomenon. Here only introduce pump failure and inspection method. Exterior inspection: to check motor that maybe don’t work, or rotate in opposite direction, or lose V wheel. Reversal result from wrongly connecting two phase wire in motor or power supply. Adjusting strength of V wheel or changing a new one deal with wheel slip. However, the reason that motor don’t work are several, either electric or mechanical failure. Disconnecting V wheel at first,

compassion still has far to go. © 2006 .  About sponsorship Overview Nov 30th 2006 From The Economist print edition The dollar fell, breaching the threshold of $1.30 to the euro. It slid to its weakest rate against Europe s single currency since March 2005, and its weakest against the British pound since December 2004. However, on a trade-weighted basis, the dollar was no cheaper than in the spring. America s currency was not helped by discouraging reports on its housing market. Sales of newly-built homes fell by 3.2% in October, according to the Census Bureau, leaving them more than 25% below their level in October 2005. Although sales of already-existing homes rose by 0.5% in October, according to the National Association of Realtors, the median price was flat compared with the month before, and 3.5% below its level a year earlier. Consumer confidence fell for the second month in a row in America, according to the Conference Board s November survey. The omens for investment do not look good either new orders for capital goods, fuel dispenser excluding defence and aircraft orders, fell by 5.1% in October. At least last quarter looks brighter than it did. Revised figures suggest that America s GDP grew at an annual pace of 2.2% in the three months to September, not 1.6% as prev fuel dispenser iously estimated. Corporate profits (adjusted for declines fuel dispenser in inventories and depreciation of capital) rose by 30.9% in the year to the third quarter. New figures show that Germany s slowdown in the third quarter (its GDP grew by only 0.6%, after a 1.1% gain in the previous three months) was due to a fall in the stock of inventories, which will need to be rebuilt soon. The stock-clearing obscured a 0.7% gain in private consumption, the biggest quarterly increase in almost two years. The fourth quarter also looks encouraging for Germany. Business was brisk in November, according to the Ifo business-climate index, which equalled
