buoyancy material

The exhibit introduces the role played by pressure resistant solid buoyancy materials in unpowered buoyancy technology through interactive learning, allowing visitors to experience the working principles of deep-sea submersible surfacing and diving. 1. Turn on the button, activate the device, select the float/dive start button, and the submersible will operate; 2. visitors controls the weight of the submersible by throwing it through a cast iron electromagnetic controlled by a pull rod; 3. visitors cooperates with the cast iron casting operation and sequentially observes the ascent and descent process of the submersible through the status of the air and water tank devices on both sides; 4. Watch the buoyancy material model and provide graphic and textual explanations. Unpowered floating and diving: When diving, load counterweights and inject water into the pressurized water tank to make its gravity greater than buoyancy and sink. When floating, discard the counterweight and inject air to reduce weight and ascend by buoyancy. Buoyancy material: it is a low-density, high-strength composite foam material, which has the characteristics of resistance to hydrostatic pressure, seawater corrosion and low water absorption. In a round-trip deep-sea submersible, it.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
