A diesel transfer tank requires several essential accessories to function properly and safely. Here is a detailed introduction:
- Pipes and Fittings: High - quality fuel - resistant pipes are needed to connect the tank to the dispensing equipment or other fuel - using devices. Fittings such as elbows, tees, and couplings are used to join the pipes and ensure a tight seal. These should be made of materials compatible with diesel to prevent corrosion and leaks.
- Valves: Various valves are essential for controlling the flow of diesel. A shut - off valve is installed at the outlet of the tank to stop the fuel flow when needed. A check valve can be installed to prevent back - flow of fuel. Additionally, a pressure - relief valve is necessary to protect the tank from over - pressure in case of any malfunctions.
- Fuel Gauge: A fuel gauge is crucial for monitoring the fuel level in the tank. It can be a mechanical or electronic device. The mechanical gauges usually work with a float - based system, while the electronic ones are more accurate and often come with digital displays.
- Grounding Equipment: To prevent static electricity buildup, which can cause fires or explosions, proper grounding equipment is necessary. This includes a grounding wire and a grounding rod. The wire should be connected to the tank and the rod driven into the ground to dissipate any static charge.
- Nozzle and Hose: A dispensing nozzle and hose are required for transferring diesel from the tank to the receiving equipment, such as vehicles or generators. The nozzle should have a proper grip and a trigger - type mechanism for easy operation and precise control of the fuel flow. The hose should be flexible, durable, and resistant to diesel.
- Ventilation System: A ventilation system is needed to allow the escape of fuel vapors and prevent the buildup of pressure inside the tank. This usually consists of a vent pipe with a flame arrester to prevent any external flames from entering the tank.
-
Protection Equipment: To protect the tank from physical damage and the elements, accessories like tank covers and guards can be installed. Covers can prevent debris and rain from entering the tank, while guards can protect the tank from impacts.
