Scope of Application
It is suitable for the bottom loading and unloading of vehicles and trains for highly volatile chemical media such as liquefied petroleum gas and liquid ammonia.
This equipment is suitable for loading and unloading a variety of media for road/rail tank cars with bottom interfaces.
This equipment is especially suitable for loading and unloading operations of various media in occasions with high environmental protection requirements.
Structural Features
The vehicle connection port of the outrigger can be equipped with a quick coupling or a loose flange according to the user's selection.
The gas-liquid phase pipeline system of this equipment is of rigid pipe structure. Through the connection of the swivel joint, the pipeline system can achieve operational flexibility within a large envelope range, thus simplifying the operation procedure and expanding the application scope of the equipment. Its features are as follows:
- The pipeline is equipped with a swivel joint to achieve three-dimensional movement of the arm;
- The spring cylinder balance system balances the bending moment generated by the outer arm and front-end components;
- The vehicle connection port of the outrigger can be connected with a quick coupling or a loose flange as selected by the user;
- The main sealing ring of the swivel joint is of the structure of reinforced PTFE + stainless steel spring steel clamp, which has good self-lubrication and wear resistance and can achieve self-compensation during wear.
- A spring balance mechanism is adopted to balance the gravitational moment of the outer arm, and the unbalanced moment is less than 5Kg.M, making the operation light and labor-saving.
- An anti-static device is equipped, which can effectively eliminate the stray charges generated by the liquid flow during the loading and unloading operations.
- An inner arm locking mechanism is equipped to effectively reset the arm when it is not in use.
- It is simple to install and maintain, and convenient for repair.
