Mechanism for forming a seal around the shaft of a liquid pump |
摘要 |
A mechanism for forming a liquid-tight seal around the rotary shaft of a liquid pump having a stationary ring attached to the casing of the pump and a rotating ring attached to the rotary shaft and contacting the stationary ring. The stationary ring is formed from baked carbon, while the rotating ring is a sintered product of silicon nitride. The stationary ring has an effective seal width ratio, rp/Di, of 0.07/1 to 0.22/1, where rp is the width of the effective seal surface of the stationary ring and Di is its inside diameter.
