Y type’s centrifugal pump
    Y type’s centrifugal pump is used to transport the oil product in which there is not solid grain. The
temperature of the transported medium is from -20℃～+400℃,the flow capacity is from 6.25 to 500 stere per hour, the lift height is from 60 to 63 meters.
Y type pump is classified into three kinds: 1, single step and two steps cantilever centrifugal pump, 2, single step and two steps supported by two sides centrifugal pump. 3, multilevel subsection centrifugal pump.
Single step cantilever pump adopts impellers with balance aperture and double ring to balance; two step cantilever and two step two sides’ supporting pump adopt impellers symmetry to balance, multilevel subsection centrifugal pump adopts balance tray to balance, other Y types pumps adopt rolling bearing to support, the rolling bearing and sliding bearing both adopt lube to lubricate without water cooling room.
Slurry Pump
    Summary

  GZ types solid and liquid Slurry Pump is designed by Tsinghua University according to the theory about solid and liquid flow velocity which is issued latest internationally, that is classified into GZ type and GZL type, and also can be classified into 250mm, 200mm, 150mm, 100mm, 75mm, and 50mm by the diameter, it can make the energy transformed fully, reduced the ablation, advanced waterpower design, reasonable structure design, matching the high rigidity and wearable material-Cr15M3 make the efficiency higher, useful life longer, run-time more reliable, so it can be used widely by mine ,metallurgy, electric power, coal and other industry department to transport coal mud, slurry and strong abrasion and high thickness, the highest thickness is 45 percent for ash slurry,60 percent for mine slurry.



  Structure explanation

  1.pump head part
GZ type pump is double pump shell, there is renewable metal liner in pump body, and pump body adopts cast iron, connecting with bolts. The pump mouse and bracket are connected with bolts. The exit of pump can be installed by eight points, there is back laminas on the fore-and-aft boards of impellers which can reduce the leak and increase the pump useful-life,
  2.axes seal part
It adopts adopt two modalities (assistant impeller seal and filling seal), repair cycle is long, reduced the maintaining workload, at same time extend the useful-life.
  3.running part
it include bracket and bearing, the diameter of the pump axes is large, rigidity good and cantilever short,
Which won't bend and liberate in the poor conditions, the pump axes adopt taper roller bearing and column roller bearing, the bearing adopts axunge and sparse oil to lubricate, there are airproof cover and mazing sheath and mazing rings in two sides of bearing which can prevent the feculences into bearing, ensure the security of the bearing.
