Ammonia is an important chemical raw material. For the convenience of transportation and storage, liquid ammonia is usually obtained by pressurizing or cooling the gaseous ammonia. Liquid ammonia has a strong pungent odor. It is a corrosive and volatile medium. It needs a special loading crane tube for loading and unloading operations. The liquid ammonia crane tube is used as the crane tube for liquid ammonia loading and unloading operations. .
product structure:
1. Pillar: It plays a supporting role and can withstand the turning moment when the arm is deployed.
2. Inner arm: the basic component of arm movement and conveying medium.
3. Outer arm: the basic component of arm movement and conveying medium.
4. Outreach arm: It can feed the medium into the tanker.
5. Spring cylinder balance system: balance the heavy moment of the vertical pipe and the outer arm, and reduce the resistance of the outer arm to move up and down.
