but also container, vacuum pump. The hose made according to GB10543 consists of inner rubber layer, enhancing layer, conductible metal line and exterior rubber layer. Whichever hose abided by the requirements of GB/T9081-2001 Fuel dispenser for vehicle and JJG443-98 Fuel Dispenser in terms of safety and accuracy. During operation pay much attention to protect hose: avoid as much crook as possible; prevent pressure on hose; avoid and reduce abrasion with ground. 4. Connection and seal about pipeline and hydraulic elements Each part of fuel dispenser adopts pipeline connection, dividing into hard type and soft type. In hard type connect fuel dispenser ion steel pipe, brass pipe and aluminum pipe are adopted as pipeline, but in soft type one hose and corrugated pipe. Connected components includes relative elbow jointer, flange and fuel dispenser directive jointer. There are following seal types: cone-shaped seal, subulate thread seal, O-ring seal, rubber and asbestos gasket, cork and rubber board, engineering rubber board. According to regulation stipulated in GB/T9081 every fuel dispenser should be conducted sealability testing before leaving factory, no leakage found under normal operation. As replace some parts or found leakage these problems should be paid attention: Cone-shaped seal structure Cone-shaped seal structure also called as expanding jointer, which is composed of pipe with outstretched end, flat spout and outside thread bushing. Sealability is ensured through tightly integration of subulate surfaces. In disassembling or reassembling cone-shaped seal structure pays much attention not to hurt or broken sublatae surfaces, cleaning waste. Thread airproof As disconnection or reassembly thread surface should be kept clean, daubing seal glue or seal belt before installation. O-ring seal Most manufacturers adopts national standard to design O-ring seal, reaching a good sealability. However, some parts is impossible to adopt national standards because of specific structure. Thus, user should purchase or employ appropri fuel dispenser

Middle East and Africa; the region is the world s most difficult place to enforce contracts. Raising the sustainable rate of growth is a long-term task. In the meantime, there are two big challenges. The first is to stay out of trouble if and when the world economy weakens. That points to the need for tighter fiscal policy. Brazil s public spending saddles the economy with intolerable tax and interest rates. Only Chile and Mexico (to a lesser extent) are saving some of the windfall gains from the commodity boom to spend them when times are hard. Contrast that with Venezuela s Hugo Chávez, who is spending his oil windfall as fast as it c fuel dispenser omes in. The second problem is enduring poverty and inequality. If many Latin Americans still see the fruits of reform as disappointing, that is because poverty rates do not see fuel dispenser m to be falling as fast as they should be (see chart 3). That is partly because income distribution in Latin America is more unequal than anywhere outside Africa. According to a recent report by the World Bank, widespread poverty can itself be a drag on growth.* The poor cannot take a full part in the economy. That points to giving priority to policies which simultaneously increase growth and reduce poverty. Examples include investment in education and in infrastructure, according to Guillermo Perry, the bank s chief economist for Latin America. These findings also add an economic argument to the political case for well-designed anti-poverty programmes. In the past few years, several of the region s governments—including those in Mexico, Brazil and Colombia—have started to adopt these on a large scale. Some 50m Latin Americans are now enrolled in schemes which pay them a small monthly stipend in return for keeping their children in school and taking them for regular health checks. There is plenty of evidence that such policies are starting to work. In Mexico, where they were pioneered, extreme poverty fell by half between 1998-2004, despite only moderate economic growth.
