As global industrial operations demand higher efficiency, reduced downtime, and greater equipment longevity, the role of specialized sealing technology has become more critical than ever. Huangshi Rviton Machinery Co., Ltd., a premier Chinese manufacturer with over 20 years of expertise in the sealing industry, has announced the expansion of its global distribution network. The company is set to deliver its advanced Mechanical Face Seal portfolio to key markets across North America, Europe, and Asia-Pacific, addressing critical sealing challenges in construction, mining, agriculture, and renewable energy sectors.
As global infrastructure projects expand and mining operations push the limits of heavy machinery, the demand for high-end, reliable sealing components has reached an all-time high. At the forefront of this industrial demand is Huangshi Rviton Machinery Co., Ltd., a premier Chinese manufacturer specializing in the research, development, and production of heavy-duty mechanical face seals. Known globally as a pioneer in the industry, the company’s signature product line, the duo cone seal, is increasingly becoming the preferred choice for original equipment manufacturers (OEMs) and aftermarket distributors worldwide.
The global heavy equipment industry is undergoing a significant shift as construction, mining, and agricultural sectors demand longer operational lifespans and reduced maintenance downtime. At the forefront of this industrial evolution is Huangshi Rviton Machinery Co., Ltd. (professionally known as RVTON), a premier manufacturer specializing in the research, development, and production of heavy-duty duo cone seal technology.
The maintenance of the cooling state of the floating oil seal is to maintain the normal form of the seal, and at low speed, light lubricating oil, when the internal and external pressure difference is large, the axial clearance or swing is large, the contact pressure of the sealing surface is usually increased. , To ensure reliable sealing. Under high-speed conditions, the lubricating oil will be thrown away from the sealing surface under the action of centrifugal force, making the sealing surface lack of lubrication, and the centrifugal force will raise the sealing surface of the floating seal ring, increase the angle of the back cone surface, and make the sealing surface contact the specific pressure Increase. These two reasons can easily cause the sealing surface to burn out.
Therefore, under the conditions of high linear velocity or high ambient temperature, it is usually chosen to reduce the contact pressure of the sealing surface. The maximum linear velocity of the floating oil seal is generally required for the floating seal ring of bearing steel not to exceed 1m/s, and for the casted floating seal ring not to exceed 3m/s, and varies with the material of the floating seal ring. This is a control method to ensure the cooling state of the floating oil seal.
Through maintenance means to maintain the cooling state of the floating oil seal, the lubricating oil obviously cannot be ignored. The lubricating oil not only provides lubrication for the sealing surface of the floating seal ring, but also plays a role in cooling the floating seal ring. Therefore, the lubricating oil must be immersed at least 1/3 of the floating oil seal in order to lubricate and cool the floating seal ring normally. Generally, it is recommended to immerse to 1/2~2/3 of the floating oil seal, especially for floating seal rings with general wear resistance or floating seal rings lacking fine texture on the surface.
