Translation to English: “Oil tanker trucks belong to specialized vehicles. Unlike regular cars, oil tanker trucks can be equipped with optional configurations according to specific needs, enabling them to serve various specialized functions. Common optional configurations for oil tanker trucks include:
-
High-flow refueling pump
Structure: The high-flow refueling pump is installed inside the toolbox of the oil tanker truck. Two oil hoses connect to the delivery pipeline: one hose is used for fuel transport and the other for returning fuel to prevent hose burst due to pressure. Taking the Zhengxing high-flow refueling pump as an example, it achieves a flow rate of around 80 liters per minute.
Purpose: An oil tanker truck equipped with a refueling pump, also known as a mobile refueling vehicle, is primarily used for refueling cars or construction vehicles on-site.
-
Compartmentalized oil tanker truck
Structure: By default, an oil tanker truck comes with a single compartment. Adding compartments, as the name suggests, involves converting one compartment into two by inserting a sealed partition layer in the middle of the tank body. The material of the partition is identical to that of the tank body. After compartmentalization, it typically requires the addition of a set of European standard tank ports, a set of bottom loading equipment, and a set of pump-in and pump-out systems.
Purpose: Compartmentalized oil tanker trucks are primarily used for transporting gasoline. As we all know, gasoline comes in different grades such as 92, 95, and 98 octane. When there is a need to transport different grades of fuel simultaneously, compartmentalization is necessary to separate and transport them in the same vehicle.
-
Flow meter
Structure: Flow meters are typically installed on the pump-out or pump-in pipelines to electronically record the flow of oil.
Purpose: In situations where fuel dispensers are not used for measurement, some users opt for flow meters for counting purposes. There are three measurement methods for flow meters: pump-out metering (measuring when fuel is pumped out of the tank), pump-in metering (measuring when fuel is pumped into the tank), and combined pump-in and pump-out metering (measuring both operations with one flow meter).

Essential equipment for oil withdrawal from oil depots includes oil vapor recovery systems, bottom loading equipment, and spill prevention probes.
Structure: Oil vapor recovery valves and spill prevention probes are installed on the European standard tank ports located on top of the tank body. The oil vapor recovery port is installed next to the discharge valve, while the spill prevention probe detects overflow through sensing devices and triggers alarms.
Purpose: The oil vapor recovery system recycles vapors generated during loading and unloading to prevent hazardous emissions. The spill prevention probe serves as a safety device to prevent overflow and issues an alarm when the oil level reaches a critical limit, automatically shutting off valves.
-
Self-flow port
Self-flow port: This is an outlet branching off from the oil pipeline. The faster the oil tanker truck can unload, the more trips the driver can make, thereby potentially increasing earnings. The design of the self-flow port allows oil from the tank body to be released through multiple channels, enhancing the efficiency of oil discharge.

Aluminum alloy rims and vacuum tires
The lighter the weight of the vehicle, the more oil it can carry under the same total weight. When choosing an oil tanker truck, users not only consider aluminum alloy tank bodies but also pay attention to aspects such as tires and rims. Compared to steel rims, aluminum alloy rims are lighter by 10 to 15 kilograms each. For example, on a truck with four aluminum alloy rims in the front and eight in the rear, switching all rims from steel to aluminum alloy would reduce the total weight by 120 to 180 kilograms. This weight reduction allows for the transportation of an additional 120 to 180 kilograms of oil.
Ultimately, the choice of configuration depends on the specific use of the oil tanker truck: where the oil is being transported from, where it needs to go, whether weighing measurements or fuel dispensers are used, and whether flow meters are employed. These factors all need to be carefully considered in the decision-making process.
