铬27耐磨铸铁抗磨蚀性类似硬镍1#，就碱性混合液而言，具有较好的耐腐蚀性，价格高于硬镍1#，Cr15Mo3是目前世界上公认的优良抗磨蚀材质，宏观硬度高达布氏硬度对粗颗粒强磨蚀浆体有较好的抗磨蚀性能，但价格较高，且较脆。

一、产品概述SP液下渣浆泵为立式离心液下渣浆泵，浸入液下，用于输送磨蚀性、粗颗粒、高浓度渣浆。不需要任何轴封和轴封水，在吸入量不足的工况下也能正常工作。

SP型液下渣浆泵过流部件由耐磨金属制成。 

根据渣浆池液面的高低，可选择不同长度的泵传动轴或吸入管。 

采用多种速度和多种变型方式，使得泵在最佳工况下运行，使用寿命长，运行效益高，能满足多类恶劣的输送条件。 

Second, SP liquid slurry pump application Range 
Slurry pump is mainly suitable for conveying corrosive, coarse particles, high concentration slag slurry. Widely used in bbbbllurgy, mining, coal, electricity, building materials, environmental protection and other departments.
Third, SP liquid slag slurry pump structure debbbbbbion 
The difference between the slurry pump structure of SPR liquid and the slurry pump under SP liquid is only that the parts of the dipping slag slurry are lined with corrosion-resistant rubber, the parts lined with rubber include shafts, pumps, impellers, protective plates and filters, and the connecting bolts in the lower part of the immersion liquid are equipped with rubber protective sleeves, and the transmission parts and SP pumps
SP Liquid slurry pump pump body, impeller guard plate are made of wear-resistant materials. The pump end of the bearing body adopts a double row tapered roller bearing, and the driving end adopts a single row cylindrical roller bearing, which can withstand the maximum axial load of the pump. The bearing body is fitted with a motor seat or motor bracket, which can be driven by a direct or triangle belt drive. The pump should be immersed in the slurry pool to work, the pump body suction inlet with a filter, can prevent large particles into the human pump. Jdhuiquan5.15
Four, the depth of the liquid can be extended pump self-belt liquid depth of about 70cm, according to customer requirements to increase the depth of the liquid, (the price with the addition of a long number of meters and different) please customers and customer service personnel in advance to explain.

渣浆泵过流部件可选用的材质较多，应根据输送浆体的屋里（颗粒组成，粒径，形状，硬度，浓度），化学（酸，碱，油）特性而定。金属耐磨材质硬镍1#，对粗颗粒有较好的抗磨蚀性；硬镍4#抗磨蚀性与硬镍1#接近(公众泵管家)，但对于大颗粒，高应力的冲击性渣浆有较好的抗磨蚀性，价格较硬镍1#高。
