Conical Surface Details
Working surface Details
Polishing attained by lapping process.The surface flatness of ZHONO products is within 3 light bands of Optical interference of monochromatic light., our standard of the working surface roughness is ≤Ra 0.1μm
Types of O ring
Depending on the ambient and operating temperature of the face seal, the O-rings or trapezoidal rings can be made from a choice of four proven basic elastomeric materials in different grades.Each elastomeric material is highly resilient and will show very little permanent set which ensures a reliable static seal and clamping action.
NBR – standard
HNBR – higher temperatures
VMQ(silicone rubber) – covers temperature in both hot and cold extremes
FPM(Fluorine rubber) – extends the maximum temperature while offering excellent oil compatibility
Quality Control
To harvest the desired return on investment, the heavy equipment needs to run continuously and without costly breakdowns and unforeseen repair work.Our face seals'long service life is due to the use of chilled cast iron.This class of materials is very hard, resists abrasive wear and corrosion, and has excellent tribological properties.From the first contact with our customers to shipping the finished face seal we take full responsibility.
Applications
For Years together, ZHONO Mechanical Face Seals have been used by OEMs and Users of Seals with outstanding success in Construction Equipments,Transmission Drives, axles, Rollers and Argo machineries. The Special Alloy Cast iron materials Provided by ZHONO are having extraordinary capacity for wear resistance, for a verity of demanding applications, such as mining machinery, agriculture equipments, undercarriage vehicles, track rollers and many other applications.
ZHONO not only offers "off-the-shelf" designs –its engineering team is also available to work with your engineers to design 'non-standard' metal face seals.Whether developing a new seal size or type to fit your application, or utilizing a new metal seal or O-Ring material, ZHONO engineers have the experience necessary to design, procure and test these concepts and follow them to production.No matter what type you need,contact us please.
