Fuel tank trailer are divided into fuel trucks and fuel trucks. The vehicle chassis is equipped with tanks and oil drain pipes to form fuel trucks. On the basis of fuel trucks, a pump system is installed to form a fuel truck.
Fuel tank trailer have two types of tanks: elliptical and arc-rectangular cross sections. The tank has a low center of gravity and good stability. Round tanks are generally used in pressure vessels and some liquid food transport vehicles. They can withstand pressure and have a high center of gravity. The wind head has a variety of structures such as flat head, curved head, butterfly head and so on.The flow meter generally uses level 0.5, and optional level 0.2 can be divided into zero and non-zero.The transportation of crude oil, asphalt, coal tar and some chemical products requires the use of thermal insulation tanks, which are widely used.
Fuel tank trailer bottom fuel tanker includes oil and gas recovery system, anti-overflow system, bottom loading and unloading system, etc. It is docked with national standard oil and gas to realize automatic switching function. There are two types of explosion-proof upper cover, aluminum alloy and carbon steel. The upper cover breathing valve is built-in type, even if the tank body is overturned, oil leakage will not be caused by damaging the vent valve. The built-in breathing method can be installed in two Cover it.
Fuel tank trailer subsea valve and the drain valve are normally closed, and the oil will not enter the piping system. In an emergency, it can be disconnected from the bottom cutout to prevent the liquid in the tank from leaking. There are two types: manual and automatic. After the anti-overflow system is connected to the oil tank discharge overflow system, when the tank liquid level reaches the height of the probe, the oil tank pump can be automatically stopped to refuel in the tank.
Fuel tank trailer announced volume of the tank is the effective volume. That is, the calculated volume of the tank minus the internal volume of the tank body, head, wave shield and other internal accessories. The remaining net volume is the total volume of the tank, not the actual capacity. The volume of oil, minus 3% of the expansion space, is the volume of the actual oil
