on quickly increase in recent year, consumption of finished oil increase al well, the vapor pollution and resource waste in forecourt fuel dispenser become more important safety factor in considerable filing station, safety distance and vapor density in particular. At present, vapor separator device is installed and obtain content effect in most of large and middle cities reference to foreign improving measures. Its recovery principle is divided as two phases: first phase refers to closed discharge from tank vehicle; second phase refers to vapor recovery as refueling oil. Phase I vapor-recovery system The first phase system aims at to rebuild the delivery pipe and vapor recovery pipe between vehicle tank and tank. (Diagram 4-1) The volume of vapor will be increased as flowing into tank because of waves and shock. Therefore, the inlet pipe should be deeply stretched under oil level so as to reduce oil waves. As for a tank exceeding 945L of volume, inlet pipe is needed stretching into oil no higher 15cm than bottom of tank. Oil flows into tank from under level, vapor flow back into vehicle tank under pressure. In principle, the volume of oil and vapor is corrective. In order to make as little as vapor volatize during delivery, the structure of traditional ventilating pipe should be improved, making system in sealed sta fuel dispenser te under normal pressure range. Reclaimed vapor is dealt with through condensation, adsorption and burn after taking back. Its operation principle is similar to the vapor system of balanced nozzle. Diagram 4-1: Phase I Vapor Recovery System The pipeline installation is illustrating in Diagram 4-2. The height of air pipe at least 4m. The length of back air is shorter than air pipe, diameter larger than that of air pipe. It is prohibited to appear overflow phenomenon as vehicle tank discharge, shut off switch of air pipe. The jointer between air back and discharge pipe should adopt speed jointer. Phase II vapor-recovery system Phase II refers to the progress in which vapor in v fuel dispenser ehicle tank is

€œThe Overworked Americanâ€? became a best- seller by telling people something that they thought they already knew. In fact, most o fuel dispenser f the official numbers have shown that American toil has not changed that much over the past few decades. Americans may put in longer hours at the office than other countries, but that is because average hours in the workplace in other rich countries have dropped sharply. In America, official studies tend to show women working more and men less, but the average working week has been fairly constant. How then have Messrs Aguiar and Hurst uncovered a more relaxed America, where leisure has actually increased? It is partly to do with the definition of work, and partly to do with the data they base their research upon. Most American labour studies rely on well-known official surveys, such as those collected by the Bureau of Labour Statistics (BLS) and the Census Bureau, that concentrate on paid work. These are good at gleaning trends in factories and offices, but they give only a murky impression of how Americans use the rest of their time. Messrs Aguiar and Hurst think that the hours spent at your employer s are too narrow a definition of work. Americans also spend lots of time shopping, cooking, running errands and keeping house. These chores are among the main fuel dispenser reasons why people say they are so overstretched (especially working women with children). However, Messrs Aguiar and Hurst show that Americans actually spend much less time doing them than they did 40 years ago. There has been a revolution in the household economy. Appliances, home delivery, the internet, 24-hour shopping, and more varied and affordable domestic services have increased flexibility and freed up people s time. So women are devoting more hours to paying jobs, but have cut their housework and other burdensome tasks by twice as much. Men have picked up some of the slack at home; but thanks to technology and other advances, there is plenty of free time left over for them fuel dispenser as well, si
