[Case Study] High-Speed Rotary Joint (ROTOSTAT)

[Case Study] High-Speed Rotary Joint (ROTOSTAT)

Adopts a non-contact seal (radial type)! Rotary joint for hydraulic, pneumatic, and water applications!

【Issues】 Conventional rotary joints use contact seals on the rotating axis, making it difficult to handle high PV (pressure-velocity) conditions. Additionally, they have the drawback of requiring maintenance, such as seal replacement, due to high rotational torque. 【Improvements and Effects】 This product is adopted for high-speed rotating tables and spindles in machine tools, achieving low rotational torque. 【Delivery Examples】 ■ Wind Turbines: For hydraulic blade pitch control ■ Machine Tools: For high-speed rotating tables and spindles ■ Testing Machines: For high-speed rotation *For more details, please refer to the PDF document. Feel free to contact us with any inquiries.

[Case Study] Contributing to Cost Reduction and Environmental Conservation through Efficiency Improvements in Steam Management

[Case Study] Contributing to Cost Reduction and Environmental Conservation through Efficiency Improvements in Steam Management

Improve efficiency through steam management, contributing to cost reduction and environmental conservation!

At the paper manufacturing company, in the dry part of the paper machine (the machine used to produce paper), there was a high usage of steam, leading to significant costs, and frequent maintenance was causing issues in terms of time, effort, and expenses. Issues: 1. The amount of steam supplied to the cylinder dryers is high. 2. To increase production, there is a desire to increase machine speed. 3. The wear of the seal rings (carbon) in the rotary joints currently in use is rapid, leading to significant losses due to steam leakage, and maintenance requires a lot of time and effort. 4. There are temperature inconsistencies on the surface of the cylinder dryers, resulting in poor product yield. In the process of manufacturing thick paper at the paper mill, a large amount of steam is introduced into the interiors of several large cylinder dryers (approximately φ2000) to heat the surfaces and dry the paper.
