Features and advantages of the bottom loading arm

What are the advantages of the bottom loading arm? Now we will share the characteristics and advantages of the bottom loading arm, introduction to the structure characteristics of the bottom loading arm, and how to balance the loading arm if necessary.

Bottom loading arm concept: The bottom loading arm is composed of a connecting flange, an outer arm, a swivel joint, an outrigger (metal hose), a quick self-sealing dry separation valve and a balance system. Generally, the crane tube is connected with each other by 3 rotating joints and metal hoses to realize the three-dimensional movement of the arm and to ensure the correct connection with the tank truck at any position in the specified envelope space.

A new type AL bottom loading arm (bottom loading arm) produced by the fluid loading arm, the AL type bottom loading arm is equipped with a spring cylinder balancing device, which is used to balance the outer arm and outrigger and other parts and the liquid in the pipe gravity. Keep the arm in equilibrium at all times. Keep up and down lifting, rotating left and right light and flexible.

What are the characteristics of the bottom loading arm? The general characteristics of AL type bottom loading arm are as follows:

1. The integrated design of quick coupling and self-sealing valve, unique structure, convenient operation, and reliable self-sealing. It can be used for pipe connection when loading and unloading at the bottom of tanker.

2. In the process of rapid combination and rapid separation, the leakage is better than the requirements of the American Petroleum Institute API RP1004 standard.

3. Use the bottom loading arm AL type bottom loading arm to load oil, which is convenient for sealing the upper part of the tanker and convenient for oil vapor recovery.

4. Use AL type bottom loading arm to load oil, which can increase the loading flow, and it can also load multiple types of oil at the same time to improve the efficiency and safety of loading.

5. Fast self-sealing dry separation valve, made of aluminum alloy, light weight and good electrical conductivity.

6. The loading arm hanging arm is designed with a metal hose and a swivel joint head, which can be quickly docked and separated from the tank truck joint within the range of motion.

7. The loading arm swivel joint follows a zero-leakage design, and the main seal adopts a structure of PTFE plus stainless steel elastic ring; not only is the seal reliable, but also has wear compensation. The joint bearing adopts a double raceway, which can withstand harsh axial and radial moment loads, with large bearing force and flexible rotation.
