轴封型式的选择渣浆泵主要有填料密封，副叶轮密封和机械密封等轴封形式。副叶轮密封一般在倒灌工作下使用，高管压力应小于10%泵出口压力，这种轴封型式不加轴封水，但使用副叶轮密封降增加功率消耗，一般为额定功率的5%左右。填料密封需加轴封水，并保证足够的水压和水量，轴封水压等于泵出口压力加机械密封需加轴封水，密封性好，无泄漏。

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 metallurgy, mining, coal, electricity, building materials, environmental protection and other departments.
Third, SP liquid slag slurry pump structure description 
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.

性能参数，过流部件材质，密封型式和传动方式等几个主要方面。1， 泵型的选择离心式渣浆泵的类型很多，应根据浆体的性质不同选择不同类型的泵，以沃曼泵为例，重量浓度30%以下的低磨蚀渣浆可选用L型泵；高浓度强磨蚀渣浆泵可选用AH型泵；当液面高度变化较大又需侵入液下工作时，应选用SP（SPR）,KZJL型泵。当需要高扬程输送时。选用ZGB型,KZJ型或HH型泵。渣浆泵的合理选型是提高泵的使用寿命的关键因素之一。渣浆泵的合理选型包括合理选择泵型。
