China Suppliers Factory Submerged Roll Mechanical Seal Graphite-Silicon Carbide Cartridge Seal for Industrial Equipment
Product Introduction
The submerged roll mechanical seal constitutes a critical sealing method within industrial equipment. The stopper assembly body presents a circular configuration, formed by the mating assembly of two arc-shaped components. Radial bolt holes, perpendicular to the mating plane, are machined therein for the installation of radial bolts. Axial bolt holes are circumferentially distributed at equidistant intervals around the stopper assembly body for the installation of axial bolts. This utility model eliminates the need for mechanical seal adjustment. Through coordinated regulation of radial bolts and axial preload bolts, it achieves effective sealing between the moving and stationary seals. Its unique design effectively isolates process media, prevents contamination of bearing lubricants, significantly reduces unplanned downtime, and provides reliable assurance for continuous production.
Features
Featuring a spring-loaded stationary design, it effectively prevents corrosion and seizure. The sealing surfaces commonly employ hard materials such as silicon carbide, supplemented by corrosion-resistant elastomers like fluororubber, to accommodate diverse media including acids and alkalis, as well as varied temperature and pressure conditions.
The core friction pair undergoes precision machining to ensure sealing surface quality. Utilising high-performance sealing materials (e.g., fluororubber) and corrosion-resistant metals guarantees seal durability under demanding operating conditions.
This seal adopts a cartridge-type design, featuring a compact and rational structure for straightforward and rapid installation. For instance, certain models of submerged roll mechanical seals employ a ‘J’-type rubber bellows mechanism. The shaft and moving ring bellows exhibit no relative motion, eliminating wear and hysteresis phenomena while automatically compensating for axial displacement and radial runout defects.
