Fuel nozzle is a device for injecting oil into a vehicle's fuel dispenser and is the terminal piece of hydraulic system of agasoline dispenser. Fuel nozzle needs to be simple to use, have an adjustable oil supply, and be used safely and consistently. Some fuel nozzles may exhibit phenomena of decreased flow, no oil, no self-sealing, and oil leakage as a result of prolonged and frequent use. What issues might fuel nozzle experience after heavy use?
How do you resolve this? Whether debris has obstructed self-sealing hole Self-sealing will frequently occur as a result of the sundries blocking it or entering its pipeline. Cleaning barrel of refueling nozzle frequently and cleaning dirt out of fuel tank port of car prior to refueling can effectively prevent self-styled frequent failures. The solution is to remove barrel, blow self-sealing pipeline with pressure air flow, and blow debris out. Fuel nozzle itself frequently closes on its own To test whether a self-sealing hole is self-sealing for no reason, fill an open metal container with oil and add it at various gear and flow rates to prevent this hole from coming into contact with oil and oil bubbles. Switch refueling nozzle repeatedly, or submerge nozzle's muzzle in oil to make it normally self-seal. Perform this action 20 times. It can be determined that fuel nozzle is abnormal if self-sealing phenomenon occurs during refueling process for no apparent reason. Fuel nozzle's low flow is not due to self-professing, as some may believe. Fuel nozzle self-sealing mechanism's switch membrane's upper chamber spring has an excessively high elastic force. When there is little flow, the self-sealing rod cannot be raised because its spring's elastic force is insufficient to overcome low flow rate, weak air suction effect, and small pressure difference between upper and lower chambers of switch membrane. Reduce upper chamber spring of switch membrane's elastic force as a solution. Conclusion The internal rubber block of some hoses wears out over time and separates. In order to avoid damaging it, you should use it carefully and pay attention to daily maintenance, or you can buy used fuel pumps for sale to get a fully functional pump.
