Mobile gasoline stations, also referred to as skid - mounted refueling stations, have simplified the fueling process. Understanding their working principles helps to appreciate their convenience, efficiency, and safety features.
Pre - operational Setup
Before operation, mobile gasoline stations undergo transportation to their designated locations. The station’s modular design allows for easy relocation using trucks or cranes. Once on - site, technicians connect the station to a power source. This powers the various components, including the fuel pumps, control systems, and safety devices. Simultaneously, fuel is transferred from delivery trucks into the station’s storage tanks. These tanks, often equipped with double - wall construction and internal baffles, prevent fuel sloshing and leakage.
Fuel Dispensing Process
When a vehicle arrives for refueling, the driver parks near the station. The fuel dispenser contains a hose with a nozzle. First, the driver selects the appropriate fuel type on the dispenser’s control panel. The dispenser is connected to the station’s storage tanks through a pipeline system. When the trigger on the nozzle is pulled, an electric fuel pump activates. This pump draws fuel from the storage tank and pushes it through the pipeline at a regulated pressure. As the fuel flows through the dispenser, a metering device accurately measures the volume of fuel being dispensed. The measurement is then converted into a monetary value, which is displayed on the dispenser’s screen.
Safety and Monitoring Systems
Throughout the refueling process, multiple safety mechanisms are at work. An over - fill prevention system in the vehicle’s fuel tank shuts off the fuel flow when the tank reaches its capacity. Mobile gasoline stations are also equipped with vapor recovery systems. These systems capture and contain the volatile organic compounds (VOCs) that are emitted during refueling, reducing air pollution. In case of an emergency, an emergency shutdown button can be pressed to halt all fuel flow and electrical operations.
Post - refueling Operations
After refueling, the driver releases the nozzle trigger. The dispenser resets, and the fuel hose is returned to its holder. The station’s control system logs the transaction details, including the fuel type, quantity, and time of refueling. These records are useful for inventory management, accounting, and regulatory compliance.
