SP type Vertical Slurry Pump equipment material description
The material of the SP vertical Slurry Pump over-current component is a new generation of high-chromium wear-resistant alloy developed by the company based on recent scientific and technological achievements. While developing the slurry pump, our company has gathered experienced professional technicians to develop a new generation of high anti-wear materials. The metallographic structure of the material achieves a reasonable match between the hard M7C3 type carbide and the strong martensitic metal matrix, the Rockwell hardness reaches HRC58~62, has high anti-wear material and corrosion resistance, and has good comprehensive machinery. The performance, so that our company's products in the life of the overcurrent parts, compared with other similar products have greatly improved, by the user's drink.Vertical Slurry Pumps
3. SP vertical slurry pump equipment and structural features vertical slurry pumps
The SP vertical slurry pump is a vertical axial suction single-stage single-suction Centrifugal Slurry Pump. SP type slurry pump is mainly composed of impeller, volute, rear guard plate, bushing, bracket, support plate, shaft, bearing and bearing body. The impeller, the volute and the rear guard are made of high-chromium alloy cast iron. The impeller and the shaft are threaded, and the volute, the bracket and the bearing body are connected by bolts. The pump shaft and the motor can be driven by a coupling direct drive or a pulley. The bearings of the SP pump are greased. This series of pumps is a shaftless seal pump.
A, pump head structure for vertical slurry pumps
The pump body is a single-layer pump casing with small installation size and light weight.
A labyrinth gap seal is arranged between the impeller and the rear guard plate, which greatly reduces the leakage amount of the slurry, improves the volumetric efficiency, and has remarkable energy saving effect.
The impeller is provided with a back blade, which discharges the slurry in time, thereby improving the volumetric efficiency, reducing the backflow erosion and improving the life of the flowover member.
In order to prevent large particles from entering the impeller, the impeller is blocked, and a lower filter is provided at the inlet and outlet.
B, bearing body structure of vertical slurry pumps
In order to facilitate the lubrication of the bearing, and to extend the service life of the bearing, it is optimized from the hydraulic design and structural design. The radial force is reasonably distributed, and the bearing form, model, lubrication method, etc. are correctly selected, thereby achieving the requirements of low heat generation and high life of the bearing.
C, other forms of vertical slurry pumps
A liquid level line is provided on the support, and the slurry must pass through the liquid level line when the pump is started. The structure can be changed according to the actual situation of the user pool to meet the industrial and mining requirements.Vertical slurry pumps
