While searching for the right high-temperature rotary joint, it's essential to consider several key factors that define its performance and durability. A high-quality rotary joint should operate efficiently within a specific range of parameters. For instance, the rotational speed can vary between 100 RPM and 8000 RPM, while the operating pressure typically ranges from 1.0 MPa to 15 MPa. The temperature range can extend from 180°C to 350°C, making these joints suitable for demanding industrial applications.
One of the standout features of an advanced rotary joint is its balanced end-face seal design. This ensures that the pressure exerted on both sides of the seal remains nearly equal, which significantly reduces wear on the seal surfaces caused by excessive loads. Additionally, the stainless steel shaft is reinforced with a South Korean-imported polymer silicon carbide ring combined with a friction seal. This combination offers a low-friction coefficient and superior sealing capabilities, addressing issues related to corrosion and high-temperature resistance. These innovations have helped elevate the product to world-class standards.
Another critical aspect is the hollow shaft design, which has been extended to provide better access and make disassembly and assembly more convenient. This feature not only enhances operational efficiency but also contributes to the overall longevity of the rotary joint. Furthermore, the unit operates smoothly at high speeds, maintaining strong stability and offering a longer service life compared to conventional models. The auxiliary seals are crafted from Japanese-imported silicone and fluororubber, ensuring they remain resilient even under extreme heat conditions. The seal rings undergo impregnation with high-density graphite, while the stainless steel springs are specially treated to withstand high temperatures. These enhancements ensure excellent stability, rapid operation, and ease of installation.
The rotary joint's ability to withstand high temperatures depends on three primary components: the bearing, the shaft, and the seal. At Dongguan Qingbang Machinery Parts Co., Ltd., we prioritize quality by employing high-temperature-resistant bearings sourced from international suppliers. Our hollow shafts are specially treated and fitted with Korean-imported silicon carbide sealing rings. Moreover, in addition to the silicon carbide rings, our sealing components also incorporate materials from Japan. With a maximum operating temperature of up to 350°C and a warranty period ranging from one to three years, our rotary joints stand out as reliable solutions for various industrial needs.
These rotary joints find extensive application across industries such as plastic calendaring, mixers, hydraulic equipment, and coating machinery where high-temperature oils or steam are utilized. Whether you're dealing with demanding processes involving water, air, steam, hot oil, or liquids, our rotary joints are engineered to deliver consistent performance over time. By focusing on innovation and precision, we aim to provide solutions that meet the highest industry standards and exceed customer expectations.
