Be applied to novel sealing ring of double entry pump

The utility model discloses a be applied to novel sealing ring of double entry pump, include the double entry pump and establish sealing ring on the double entry pump, double entry pump and sealing ring pass through tapered structure sealing, the tapered structure is including seting up in the tapered groove on the sealing ring and the end of the tapered on being located the double entry pump, thesealing ring passes through tapered slot combination tapered and holds fixed mounting on the double entry pump, and tapered groove and the long distance sealed face of tapered end constitution, the inboard of sealing ring is equipped with the inside radius of big coefficient. The utility model discloses a forming the tapered fitting surface with the impeller choma, preventing that high -pressurefluid from flowing to the low -pressure end, not only increased sealed face matching length, liquid stream local resistance still has positive improvement effect to import liquid stream flow state toimprove pumping volume effi
