SPR-ing Slip ring Achieves New Breakthroughs in China's Deep-Sea Detection Information Transmission Technology  

As we all know, IP68 is the highest level in the waterproof rating standard for rotary connectors. So, what is a dustproof and waterproof slip ring? It is essentially a standard non-waterproof slip ring with additional protective measures.

The waterproof conductive slip rings developed and produced by SPR-ing provide solutions for transmitting power supplies and various signals through 360° rotating joints in harsh environments such as seawater.

China's oceans are a vast treasure trove. When developing marine resources, ensuring operational safety requires marine equipment to have high protection levels, including resistance to salt spray, acid, and corrosion. Many new types of equipment need to rotate 360° without restrictions while transmitting current or signals at key components, which imposes requirements on conductive slip rings in terms of salt spray resistance and moisture resistance. To address this, SPR-ing's marine engineering series slip rings offer solutions for marine operational equipment.

The SPK191012 Marine Engineering Series Slip Rings are specially designed and developed by SPR-ing to serve the country's future deep-sea marine engineering projects. Their design is tailored to withstand the pressure conditions of marine surface vessel winches and deep-sea VR robots, currently meeting the requirements of underwater operations at depths of up to -1500 meters. The internal electrical slip rings adopt modular gold-on-gold contact technology, and the optical joints use SPR-ing's combined optical coupling module structure, catering to the photoelectric transmission needs of different users.

• SPR-ing's core technology - friction pair technology: Gold-on-gold contact technology ensures an ultra-long service life with minimal wear.
• Integral lamination process: Guarantees the concentricity between the ring groove and the bearing is ≤0.02mm.
• Mirror finishing technology: Ensures the surface of the slip ring contact surface reaches Ra0.02, enabling more reliable contact.
• Precision component manufacturing process: Dimensional tolerance is <0.01mm, ensuring high precision and stable performance.
• Advanced brush wire modulation process: Brush debugging technology with near-zero pressure error extends the slip ring's service life by 1/3.
• Stainless steel housing: Resistant to pressure and corrosion.
• Optional feature: Built-in temperature and pressure compensation balance inside the slip ring.

Deep-sea detection and deep-sea archaeology are important ways to "salvage" human civilization and understand the mysteries of the oceans. As China's deep-sea technology advances toward the international advanced level, SPR-ing will provide more effective solutions for global marine exploration.
