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.
In order to ensure that the installation is accurate and in place during installation, it is required to install horizontally downwards, avoid tilting, vertical or upside-down installation. As shown in the figure, it is recommended to use the installation tool, put the installation tool on the outer circle of the floating seal ring, align the O-ring horizontally with the entrance of the floating seal seat chamber, and apply pressure to the installation tool gradually. The installation tool keeps the O-ring at the bottom of the back cone of the floating seal ring to keep its outer diameter small. In this way, the O-ring can slide into the floating seal seat chamber relatively easily. And avoid the sealing surface and O-ring being scratched. When the installation tool is lacking, a thinner and harder O-ring can also be used instead of the installation tool.
Check the position of the O-ring to make sure it is level and not twisted or arched. If so, need to adjust and restore. Check the parallelism between the sealing surface of the floating seal ring and the installation datum plane of the floating seal seat. Generally, the deflection shall not exceed 1/2000 of the outer diameter of the floating seal ring. Apply a clean lubricant film evenly on the sealing surface. When the equipment is aligned, it should be steady and gentle, and the sealing surface should not be damaged.
After the equipment is assembled, add lubricating oil according to the requirements, and test it for about 2 hours to check the oil temperature and the sealing parts for leaks and abnormal sounds.
