Product Features
1. H-type balanced mechanical seal structure, imported high-speed bearing double support, reliable structure, stable operation.
2. The main seal of the mechanical seal rotary joint is CNC precision machined to ensure surface roughness and flatness.
3. The wear amount △ of the sealing friction pair end face is extremely low under normal working conditions, and can be used continuously for 2 years, with a lifespan of 5-10 years in special occasions.
4. It has good vibration resistance, with an amplitude of no more than 0.05mm at a speed of 3000r/min, and the PV value can be continuously increased with use.
5. The power loss is small, and the friction pair of the mechanical seal is in a semi liquid friction state, with a very low friction coefficient μ.
6. The insensitivity of the rotating shaft to vibration and the deflection of the hollow shaft to the shell makes the bellows sealing shaft or shaft sleeve less susceptible to wear.
7. Mechanical seal rotary joints can ensure the reliability of sealing under extremely harsh working conditions with flammable, explosive, toxic and harmful media in circulation.
8. It has a wide range of applicable working conditions, with good performance in high temperature, low temperature, high pressure, vacuum dry friction, and high-speed working conditions of corrosive media.
9. Fluid design scheme allows for direct replacement of sealing components on the production line, facilitating maintenance and repair.
10. Rust proof slag separates sediment and is suitable for working environments with solids and particles in the circulating medium.
11. Linear velocity: ≤ 15m/s, axial displacement: ± 1.0mm.

Main application scenarios
Widely used in rotary drum equipment that requires cooling water or heat medium circulation, such as paper dryers, rubber calenders, textile printing and dyeing, plastic extruders, and chemical drying equipment, to solve the problems of medium transmission and leakage prevention under high-speed rotation. ‌‌
Key points for installation and maintenance
Rotation matching: Before installation, it is necessary to confirm the rotation direction of the equipment. Choose the right-hand thread counterclockwise and the left-hand thread clockwise to prevent loosening.
Flexible connection: Metal hoses must be used to connect the inlet and outlet pipes, and direct connection of hard pipes is prohibited to compensate for eccentricity and thermal expansion and contraction.
Anti pollution measures: It is recommended to install a filter at the inlet of the medium to prevent foreign objects such as iron filings and scale from damaging the sealing end face.
Maintenance inspection: Regularly observe the leakage situation. The normal wear of the sealing surface is about 5-10mm. If scratches or intermittent contact occur, it should be replaced in a timely manner; Long term disuse requires rust and scaling prevention. ‌‌
