Performance and Purpose

This end-facing seal has a “Y”-shaped cross section. It is designed specifically for steel pipe hydro-static testing machines to seal the plane on water filling and air exhaust test heads. Close contact between the two planes is required during installation, and attention should be paid to the installation direction of the sealing ring.

Description

Mechanical Seal Ring

Mechanical seal rings are components in a mechanical seal that are used to create a leak-proof seal between rotating and stationary components in equipment, such as pumps and mixers. They are typically made of materials that have low friction and high wear resistance, such as carbon, ceramic, or tungsten carbide. The mechanical seal rings work together to maintain the seal, even under high pressure and temperature, to prevent fluid or gas from escaping.

Mechanical seal rings are used to seal the gap between the rotating shaft and the stationary housing in equipment such as pumps and mixers, so that liquid cannot escape through the gap. These sealing mechanisms are often referred to as shaft seals or pump seals.
Jk manufactures primary rings or carbon/graphite wear surfaces that are used in many of the most sophisticated and reliable mechanical seals used in industrial, aerospace and military applications today. These mechanical seal assemblies typically consist of a carbon/graphite primary seal ring, mating face ring, secondary (O-ring) seal ring, spring, fasteners and metal housing.
Mechanical seal main rings can be supplied to customer drawings and specifications. These rings can be supplied plain, heat shrink fit or bonded in a metal retaining ring

Mechanical seal assemblies are also used to seal gas in high speed compressors. These dry gas seals are double mechanical seals that utilize controlled barrier gases and helical grooves in the mating surfaces to provide pneumatic lift or gas lubrication between sealing surfaces.

Mechanical seal primary rings are available from customer drawings and specifications. These rings can be supplied plain, heat shrink fit or bonded in a metal retaining ring.JK Mechanical Seal Rings can also be supplied with sealing faces ground flat to heliostat.

Advantages

  1. The support skeleton enhances the overall strength of the seal ring and the sealing capacity of the sealing ring can be increased by working pressure.
  2. The sealing material has the advantage of high strength, high hardness and good elasticity
