on quickly increase in recent year, consumption of finished oil increase al well, the vapor pollution and resource waste in forecourt 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 reco fuel dispenser very 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 state under normal pressure range. R fuel dispenser eclaimed 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 Vapo fuel dispenser r 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 vehicle tank is

city folk have forgotten about them.  © 2006 .  About sponsorship Nepal Poised between revolutions? Aug 24th 2006 | KATHMANDU From The Economist print edition Having successfully ousted a king, Nepal is still looking for peace JUST four months after huge demonstrations forced King Gyanendra to relinquish absolute power, protest has be fuel dispenser come a way of life in Nepal. Its latest success came on August 20th, when, after violent demonstrations in Kathmandu and elsewhere, the government rescinded its attempt to raise the prices of kerosene, diesel and petrol. Unfortunately, the goal that motivated many to join the original revolt earlier this year is proving harder to reach a lasting peace in the ten-year civil war with Maoist insurgents. AP Prachanda the potential Octobrist Still, it seems tantalisingly close. The Maoists are observing a ceasefire, and in June agreed to join an interim government with the seven-party alliance of democratic parties that backs Girija Prasad Koirala, the prime minister. There would then be elections—as early as next April—to an assembly to draft a new constitution. This month the Maoists accepted that their fighters woul fuel dispenser d be confined to cantonments, where the United Nations would monitor them. The government s army would be confined to its barracks. A beefed-up United Nations presence, to be led by Ian Martin fuel dispenser , a veteran of the transition in East Timor, and now head of a much-praised UN human-rights operation in Nepal, is to be announced shortly. Every element of this seemingly neat arrangement, however, is uncertain. The parties, for example, are loth to let the Maoists join the government until they have disarmed. But so far they have not even agreed to be separated from their weapons in the cantonments. “Unless and until this reactionary, cruel, ruthless royal army is disb
