Crane is a rotating flexible tube, sealing good rotary joint and pipe series, the trestle between tankers and storage pipeline for liquid medium transport for device operation.
The key component rotary joint, using precision CNC machining, containing double roller support structure, rotating flexible, lightweight and reliable. Selection of steel outer, inner lining made of stainless steel or Teflon, to ensure its safe and reliable for high temperature, low temperature, strong corrosive media.
Seal with PTFE material, lined with stainless steel elastic support ring, seal polished, has excellent self-lubricating properties and superior corrosion resistance.
Bottoms crane tube
Crane tube (land use fluid handling arm) is connected to the pipeline using a rotary joint, elbow up, for loading station and road / rail transport liquids or gas products between specialized equipment tankers, to replace the old hose filling loaded with high security, flexibility and economy characteristics.
Medium: LPG, ammonia, dimethyl ether, high volatile chemical medium
Crane tube (land use fluid handling arm some parts description)
Rotary joint presentation
Swivel joints using precision CNC machining, large capacity, flexible rotation, for liquid and gaseous media having the desired sealing effect, can be safely and reliably used at room temperature, low temperature, high temperature, corrosive media, the primary seal and secondary seal and dust seal effective to achieve zero leakage. Rotary joint designed for a variety of structural forms, ranging from a simple structure to internal heating of steel lining PTFE structure, single roller, double and triple raceway raceway. Rotary joint is removable without disassembling the whole arm when replacing the seals, and can be easily replaced. Both sides are flanged rotary joint structure makes repairs, the replacement easier and faster.
Main ring
Main ring made of graphite filled PTFE and specially treated stainless steel liner tension spring cards. Seal with PTFE, wear resistance, good sealing effect, anti-aging, and other characteristics, in order to increase the elastic lining snap ring, when after long-term operation of the sealing surface wear, snap to a certain extent realized within the scope of compensation.
Secondary seal
And the main seal structure similar to the axial direction of the opening, has a good compensation performance.
Dust seal
Dust seal and secondary seal similar to prevent moisture and dust from entering the raceway.
