The cryogenic oxygen, argon and nitrogen liquid transport semi-trailer is a professional equipment specially used for transporting cryogenic liquid oxygen, argon and nitrogen. Its tank body adopts a unique structure. The inner tank is made of low-carbon or ultra-low-carbon stainless steel that is resistant to low-temperature corrosion. The outer shell is made of container-specific steel plate. The high-vacuum multi-layer insulation layer of the interlayer effectively reduces heat transfer and ensures the stable storage of cryogenic liquid.
The vehicle is equipped with a complete valve instrumentation system, including pressure gauges, liquid level gauges, safety valves, etc., which can monitor and accurately control the state of the liquid in the tank in real time. The supercharger is used to increase the pressure when discharging the liquid, and the infusion tube uses a stainless steel braided hose for easy connection and loading and unloading. The frame adopts a low center of gravity design and is equipped with a dual-circuit air brake system to ensure safe and stable driving.

♦Product advantages:
High safety performance
1. Rich safety configuration: Equipped with a variety of safety devices, such as safety valves to prevent excessive pressure in the tank, liquid level gauges to monitor the liquid level in real time to prevent overfilling or emptying the tank, and pressure gauges to facilitate the understanding of the pressure in the tank. These devices work together to effectively reduce the safety risks during transportation.
2. High vacuum multi-layer insulation: The high vacuum multi-layer insulation structure of the tank body can not only effectively maintain the temperature of the cryogenic liquid, but also prevent the liquid from vaporizing and expanding due to external heat transfer, reducing the potential risk of explosion.
3. Reliable braking system: The dual-circuit air brake system is equipped with good-performance brake pads and brake drums, with rapid braking response and short braking distance. It can stop in time in an emergency to ensure the safety of the vehicle and cargo.
Good operation convenience
1. Humanized design: The valve instrument box is centrally arranged at the rear of the vehicle, which is convenient for operators to operate and monitor when loading and unloading liquids, and the operation interface is simple and easy to understand, reducing the difficulty and labor intensity of operators.
2. Rich optional functions: 3-axis EBS, high-precision mass flowmeter, axle counter and other functions can be selected according to customer needs to meet the personalized operation needs of different customers. For example, the mass flowmeter can accurately measure the weight of loading and unloading liquid, which is convenient for management and settlement.
Superior vehicle performance
1. Lightweight design: The whole vehicle adopts lightweight design and independently develops the running mechanism frame. On the premise of ensuring the strength and safety of the vehicle, it reduces the weight of the vehicle body, reduces fuel consumption and operating costs, and also increases the vehicle’s payload.
2. Good driving stability: The low center of gravity frame combined with a good suspension system makes the vehicle more stable during driving, reduces bumps and shaking, which is not only conducive to protecting the safety of the goods, but also reduces damage to the road surface, and improves the driving safety and comfort of the vehicle.
