water pressure Tube expanding machine

The water pressure tube expanding machine is composed of three parts, Control system, Pressurization system, Expansion joint. The electric control is controlled by PLC. The gas drive supercharging system adopts two high-pressure liquid superchargers, which can rapidly boost the pressure,

The pressure rise time within a pipe diameter of 25mm and a length of 5m can reach the predetermined pressure within tens of seconds. It includes three parts: booster host, high pressure rubber hose and expanding ferrule tooling.

The heat exchanger is composed of multiple tubes, fins and supports, As the thickness of the heat sink tube is small and there are many heat sink fins, it is necessary to eliminate the gap between the tube and fins, The interference fit shall be achieved to prevent looseness. Achieve the function of tube expander.

water pressure Tube expanding machine

characteristic:

• The pressure holding time and expansion pressure can be set at will to ensure the expansion quality;
• Foot switch control is convenient for operation
• The speed of pressure rise and relief is fast, and the expansion speed is doubled;
• Heat sink tubes and fins with a thickness of 0-3mm shall be uniformly expanded in full thickness at one time;
• The residual stress of the expanded device is low, and it is not easy to produce gap corrosion;
• The axial direction of the heat exchanger does not stretch but shrinks slightly after expansion, which is conducive to reducing operating noise;
• There is no pollution at the expansion joint, and the expansion before welding is not affected;
• This equipment can also be used for the built-in steel ball extrusion connection of conventional heat sink tubes
