Centrifugal desulphurization slurry pumps for thermal power plant slurry pump

 Series of TL(R) FGD desulphurization pump is a single stage single suction horizontal centrifugal slurry pump. It is mainly used as the circulating pump for absorbent tower in FGD appliances.

Desulphurization Slurry Pumps structure

Desulphurization pumps Specification

Inlet Diameter:16 ~ 47inches(400~1200mm)

Discharge Diameter: 14~39 inches(350 ~1000mm)

Flow Capacity: 260 ~4900m³/h

Head: 10~75m

Technical Characteristics

♠Simple structure; long service life; easy maintenance; low operating cost and long life of quick-wear parts.

♠The position of the impeller can be changed by adjusting bearing assembly and the pump unit can be in high efficiency operation state. 

♠The wet parts are designed with advanced CFD(Computional Fluid Dynamics )Flowing Simulating Analysis Techniques to ensure the reliable and efficient working.

♠Double-row tapered roller bearing is fixed at the pump end and the cylindrical roller bearing is equipped at the driving end.The bearing is lubricated by diluted oil.

♠Mechanical seal is adopted with container type which is specialized in FGD technology to ensure reliable operation.

♠The bearing layer and the abrasion resistant layer can be separated.

♠The outlet of the pump is vertical.The pump runs clockwise viewed at the drive end.

♠X-type frame can save much space.And the pump adopts directed coupling connection.

FGD pump parts- cover plate& frame plate

Slurry pump cover plate & frame plate for heavy duty centrifugal slurry pump in axial direction is used to bear pressure,and the liner is wear-resistant .

 

 

FGD pump parts-shaft sleeve

With ceramic coating----high hardness and fracture
toughness and wear resistant.Shaft sleeve manage wear to minimize shaft cost.Whereever there is a bearing support for the shaft, centrifugally cast shaft sleeves are used to prevent wear to the shaft. Refurbishment of the shaft is simply a matter of replacing the sleeve and reusing the shaft.  

 

 

 

FGD pump parts-bearing assembly

Bearing assembly uses cylindrical structure, adjusting the space between impeller & front liner easily, being removed completely when being repaired. 

 

Note : The materials could be changed according to the customer's requirements .
