This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel fuel dispenser dispenser. At that time, the normal working state will be affected, which is harmful to staff’s health due to intensive noise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic modulus of pipe material J ── inertial moment of pipe section g── acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above formula: A ──pipe section m ──liquid weight in per meter of pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two frequencies as much different as possible so as to appear pipe resonance in fuel dispenser. 3. Hose used for fuel dispenser There ar fuel dispenser e two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the other kind of hose is u fuel dispenser sed in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle,

ge 160km (100 miles) north-east of the Somali capital Mogadishu, recently spotted a foreign fishing boat trawling just offshore. Incensed, they jumped into small boats to head it off. They were fired on before they could get near. No one was killed in the ensuing battle, except for sheep picking along the beach behind. Still, the locals were depressed. Foreign boats without flags or markings have been stealing their fish for years. Once, they could scare them off with a fuel dispenser shout and a rocket-propelled grenade-launcher. No longer. These days, the fishermen say, the unmarked vessels carry 23mm anti-aircraft guns. East African waters, off the coasts of Somalia, Kenya and Tanzania, have vast numbers of commercial fish species. As in other countries, east Africans enjoy exclusive fishing rights up to 370km (200 nautical miles) off their shores, but the rich pickings are attracting a growing number of intruders. The prize catch is the yellowfin tuna, which lures Taiwanese and South Korean longliners from the Seychelles into Somali waters, where the catch is a potential bonanza. But the risks are high, especially off ungoverned Somalia. Even with anti-aircraft guns, some of the vessels are still captured by Somali “coastal patrols� In a recent case, a South Korean boat, the Dongwon-ho, was released after four months in return for $800,000; “a fine� the Somalis said, “a ransom� to the South Koreans. Some longliners used to buy fishing licences in the past, but invariably from the wrong warlord. The situation is only a little better in Kenya and Tanzania. In both countries a lack of capital has produced pitiful fishing fleets. Corruption, rife enough on land, is even worse at se fuel dispenser a. Illegal and unreported fishing accounts for much of the catch. Marine conservationists say that pretty much everything is wrong with the fishing in east Africa. There is no compliance, limited mon fuel dispenser itoring and the boats use gear that rips up the seabed and, in some places, the coral reefs. Fish stocks are fal
