Novel multistage centrifugal pump

Номер: CN0101865138A
Принадлежит:

The invention relates to a novel multistage centrifugal pump. A pump shaft is provided with a group of impellers and guide vanes. Runners among the impellers are communicated in the middle. A last stage impeller is connected with a water spray section. The rear side of the last stage impeller is provided with a post axial force balancing device. The post axial force balancing device consists of a balancing drum arranged on the pump shaft, a balancing drum sleeve sleeved outside the balancing drum and a balancing chamber, wherein a gap is reserved between the balancing drum and the balancing drum sleeve; and the surface of the balancing drum is provided with a plurality of axial grooves. The invention has the advantages that: (1) the leakage from the radial gap between the balancing drum and the balancing drum sleeve is small, so difference between front and rear pressures of the balancing drum is increased so large as to make the balancing of the axial force by the balancing drum convenient ...

Novel high-efficient energy-saving pump

Номер: CN0101709720B
Принадлежит:

The invention discloses a novel high-efficient energy-saving pump, comprising a water sucking chamber, an impeller, a pump body, a pump body seal ring and an impeller seal ring, wherein the water sucking chamber is composed of a straight cone-shaped water sucking chamber and a straight tube section of the outlet end of the straight cone-shaped water sucking chamber; the straight tube section is internally provided with an inclined clapboard. The novel high-efficient energy-saving pump of the invention has the beneficial effects that the circumferential circulation exists in the liquid flow atthe outlet of the water sucking chamber, the impact loss of the impeller inlet is reduced, and the pump efficiency is improved; the leakage rate of the gap between a seal ring and a lengthening cut-water is reduced, and the leakage lose is lowered; and the seal ring has good sealing performance and long service life, and is especially suitable for application occasions where conveying medium contains ...
