Carbon graphite, ceramic and tungsten carbide friction pairs for mechanical seals:

Figure 2-43 shows the curves of the other three sets of friction pairs that replace the cartridge Chesterton GSS mechanical seal. The test friction pair is carbon graphite to corrosion resistant Ni cast iron, ceramics and tungsten carbide, the medium is tap water with less than 150ppm solid particles, and the temperature is 52 degrees Celsius. Seal shaft diameter. The circumferential speed is 9.85m/s, and the load factor is 1.22. Switch to carbon graphite tungsten carbide

Friction pair, the life of the rotating ring is extended to 350%. Wear coefficient Ka of various friction pairs. Correspondingly.　　419.html,
