Working Principle of European Standard Fuel Tank Truck

2020-07-17

The conventional configuration of the previous tank truck was a dedicated oil pump with a pump in and out of the pipeline. This pipeline has two types of Wuhan carbon steel and 304 stainless steel. The fuel tank or oil tank is generally from 5 cubic meters to There are 30 cubic meters, and some semi-trailers, their volume is 55 cubic meters. In the past, the main oil intake method of the fuel tank truck was to fill the tank through the manhole above the tank body. However, in order to improve safety, our fuel tank truck production has done a bottom fueling process, which is called API system


The important components needed for the API system: the main components of the bottom tank are the exhaust gas recovery system, the anti-overflow system, the subsea valve, the European standard tank port, the probe, the SO2 socket, Anti-static system, bottom canned API connector, etc. Our main production processes are: steam purging, washing and wiping the tank; cutting the oil sump, installing subsea valves; installing the oil circuit system; installing the gas phase circuit; replacing the closed manhole cover (European standard manhole cover); Water pressure, air tightness, kerosene leak test.

This is the overall working picture of the bottom fueling process, from which we can see the importance of the electrostatic grounding belt. The static grounding device of the large gas station is mainly fixed. This is usually solved by the LPG skid station. They install one near the large land main oil depot. When each fuel truck comes over for refueling operation, it can be quickly connected and the static grounding alarm The device is a standardized anti-static product for oil loading and unloading occasions. It can not only introduce the static electricity generated during the liquid transfer process to the ground, but also automatically detect the grounding situation throughout the process. Sound the alarm when the grounding is poor or disconnected to ensure the safety of production operations.

The aluminum alloy tank truck can be divided into warehouses. Each warehouse requires an aluminum alloy tank port (also called a manhole). It can be equipped with an anti-overflow probe, a subsea valve, and an oil discharge connector (bottom) Oil valve), oil vapor recovery valve, subsea valve, also known as emergency cut-off valve, installed at the bottom of the tank body, used for refueling, easy to operate, save time, safe and environmentally friendly.


Pressure-balanced subsea valves are used in multi-tank tank trucks and can be used for separate loading and unloading of different tanks. The tee design simplifies the pipeline, reduces the load, is simple to operate, safe and reliable.


The pneumatic shut-off valve is installed at the bottom of the tank body of the tank truck and can be refueled. The internal pressure of the valve is small and the flow rate is large. There is a cut-off groove on the flange side of the valve body. Excessive force will automatically disconnect the car body pipeline and the tank body, and the automatic centering plunger and durable spring will remain sealed, and the medium in the tank will not leak, thereby ensuring the safety of the oil tank. When there is no air source or can not be opened for other reasons, the cylinder piston rod can be opened and manually opened.

The picture above is the aluminum alloy European standard tank cover, also known as the manhole cover. It is installed on the top of the oil tank, has a built-in breathing valve and emergency exhaust function, and can be installed on the manhole cover with oil and gas recovery valves, oil measuring holes, and overflow prevention. In the process of oil filling, such as the flow probe rod, etc., when the liquid level reaches the detection position, the sensor system will automatically alarm to stop the oil filling. The built-in breathing valve keeps the internal pressure of the oil tank stable during oil transportation and balances with the external pressure. Its dumping and overflow prevention design keeps the tank truck sealed in case of accidents. The emergency exhaust device has a pressure in the tank In the case of a sharp rise, it will automatically open to release the pressure in the tank, thereby preventing accidents and greatly improving the safety of oil transportation.
