Fuel Dispenser Aticle - http://www.dressupgames8.com/blog/7.html We have all read the signs and heard the stories about mobile phones causing fires at petrol stations - well does this video prove why? In the CCTV footage motorbike riders can be seen coming in and out of the forecourt with some stopping to fill up. About 10 seconds into the clip a biker flies in to the garage and goes to the opposite side of the pump from where the attendant is already filling up another tank. The biker, wearing a white shirt, can be seen reaching for his mobile phone as he sits on his bike waiting for the server. But as his bike starts to be filled, something causes a fire to erupt and set fire to the bike. Hyderabad City Police released the footage with a warning: "Don't use cell phones when you are at petrol pumps." But some of the police's Facebook friends have rubbished the force's claims. Guarav Jain said: "Dear Hyderabad Police, I really hope you use better sense when investigating real crimes than when posting warning videos. "Cell phones don't lead to fires. This is def a issue of fuel spill on what is a hot exposed engine." And Parveen Krishnan agrees:"Why does Hyderabad police think it's due to a cell phone when it's well established that this is a myth? "Cell phones do NOT cause accidents at gas stations. Never have. Not once." [ Link Details ] |
Fuel Dispenser - http://www.fueldispenser123.com A fuel dispenser is a machine that is used to pump gasoline,kerosene,petrol,diesel or other types of fuel into vehicles,accordingly,this kind of machine could be classified as Diesel Fuel Dispenser,Petrol Fuel Dispenser for example. Fuel dispenser are also known as bowsers(in Australia),gas pumps(in Norh America),or petrol pumps(in Commonwealth countries.) From the beginning of the 20th century,the fuel dispenser has experienced 4 stages:manually,mechanically,electronically and Computerized auto type. A popular fuel dispenser is logically consisted of motor, pump, computer controller, flow meter, pulse sensor and automatic nozzle, etc.Especialy,when the accuracy is out of tolerance because of use time or working condition,the accuracy can be adjusted by change coefficient on flowmeter. While the dispenser cannot recover the normal accuracy, we can open the side covers of flow meter to check the piston(like a bowl) and distribution valve sruface.Also for some mini fuel dispenser,the computer coefficient can be adjusted through keyboard,too! Typical fuel dispensers include several sections, such as hydraulic, metering, and hose/nozzle portions. The hydraulic section contains a rotary pump for drawing fuel from the storage tank and a solenoid/pilot valve to ensure that fuel flows only toward the dispenser and not back into the pump. Commercial dispensers such as those found at gas/petrol stations may house multiple units connected to different storage tanks for the purpose of supplying multiple fuels with different compositions or octane ratings. An operational fuel dispenser contains a continuously running electric motor between the storage tank and the hydraulics portion of the unit for the purpose of maintaining a partial vacuum at the rotary pump inlet. When the nozzle opens, the storage tank draws suction pressure from the inlet, causing fuel to flow toward the pumping unit. An intermediary filter removes air bubbles or suspended solids from the fuel. Fuel then flows through the pump and valve and into the metering unit. This portion includes mechanical gearboxes, as in older pumps, or piston meters and encoders to measure and distribute a specified amount of fuel or track fuel output. After the metering section, the fuel progresses through a flexible hose and into a nozzle that dispenses it into a vehicle or storage tank. Fuel dispensers range from large commercial gas pumps to simple dispenser pumps for use with portable storage tanks. [ Link Details ] |
