FUEL DISPENSER & SPARE PARTS

FUEL DISPENSER & SPARE PARTS

Fuel dispenser are used in petroleum-retail service stations for filling lightweight oil including gasoline or diesel etc. We have taken up the production of fuel dispenser since1992. Among our gigantic business portfolio, oil transfer pumps were first put on our agenda and then mechanical fuel dispensers, electronic fuel dispenser in subsequence.

Our fuel dispensers have 3 series, namely, C series, D series and S series. All of the series share the same electronic system, which consists of flow meter, combination pump, auto nozzle etc. But C series is little in size and has a general outline with hoses from the middle. And D series contains jambs with stainless steel and hoses from the top. Then S series have a novel streamline outline and hoses from the top, which is bigger in size in comparison with the other ones.

scharge, turn anticlockwise to increase discharge; reassemble hand wheel pin and lead-seal it after adjustment. Common failure and Troubleshooting The main failure of four-piston measurement transducer includes outside leakage and accuracy decline. As appear outside leakage, all seal sections should be inspected. Generally, failure will be solved through removing damaged or aging sealed components. Diagram 2-22: working principle of four-piston measurement transducer Through long time of operation, the accuracy of measurement transducer is declined due to various abrasion occurred on cam, ideal wheel, distributing valve, valve seat, and piston. From start, fuel dispenser regulating adjusting wheel makes the accuracy meet the requirements about national metrology appraisal. If still can’t reach the wanted accuracy, some abrasion examinations should be conducted, including components of piston, distributing valve and valve seat. These components surfaces are fragile to be scratched by hard grain, increasing inner leakage and accuracy decline. If appear above situation, replace piston or grind the surfaces of distributing valve and valve seat. Double soft piston measurement transducer The article will introduce the structure, working principle and maintenance. Structure This type of measurement transducer has two soft pistons, smaller than four-piston type. Appearance and partial cutaway view is i fuel dispenser llustrated in Diagram 2-23, structure and key components in Diagram 2-24. Diagram 2-23: Cutaway view and figure of four-piston measurement transducer It has two pistons formed a 120 degree angle, driven by connecting rod that force cra fuel dispenser nkshaft moving. Component cylinder is installed in parallel. The two rolling bearings respectively installed on connecting rod and crankshaft reduces the friction. The end of connecting rod contacts with bushing. The oil discharge is controlled by distributing valve that communicating with inlet and outlet. On the top of distributing valve mounted a bearing used for installing cranks
