1. Such products are manufactured, installed and detected in accordance with The Industrial Standard of People's Republic of China DZ/T0194-1997 Polyurethane Hydro-cyclones.

2、本产品具有如下结构参数；详见附页。

2. See the attached sheet for the structural parameters of such products.

3、水力旋流器结构特点：

3. Structural Features of Hydro-cyclone:

（1）产品用聚氨酯弹性体材料制作内衬，具有耐磨性强，重量轻，不为酸、碱、盐溶液腐蚀，不易老化，不发生锈蚀等优点。但不应在大于80℃时工作。

(1) The linings of such products are made of polyurethane elastomer materials. They enjoy advantages such as strong abrasion resistance, light weight, no corrosion by acid, alkali or salt solutions, no aging easily, and no rusting. However, they shall not work at temperature of higher than 80℃.

（2）本产品适用于含固体泥浆（包括低黏度溶液）的颗粒分级、浓缩、脱泥及水质净化作业，可用于选矿厂的闭路磨矿分级，尾砂输送或用于井下充填、筑坝时的尾矿浓缩，非金属矿及化工原料的粉体制备，油田钻井泥浆的除 净化，环保废水处理等作业。

(2) Such products apply to size grading, concentration, desliming, and water purification of slurry containing solid (including low-viscosity solution), close circuit of grinding and tailing transportation at ore dressing plants, tailing thickening during underground filling and damming, powder preparation of nonmetallic ores and chemical raw materials, purification of oilfield drilling slurry, wastewater treatment, etc.

（3）聚氨酯由模具浇柱而成，因此内部几何形状尺寸准确，内表面非常光滑。

(3) Polyurethane is cast by moulds. Therefore, its internal geometry size is accurate and internal surface is very smooth.

（4）给料口的形状采用螺旋线进料或渐开线进料，因此进料过程中能获得预分离作用，提高分离效率。

(4) The shape of feed inlet is spiral line or involute. Therefore, preseparation effects can be achieved during the material feeding process and separating efficiency can be improved.

（5）合理的流道结构、光滑的内表面，尽可能少的泄露点等，使得水力旋流器净化效果好，安装简单，维修方便。

(5) Reasonable flow passage, smooth internal surface, fewest possible leakage points, etc enable the hydrocyclone to produce good clarification effects and be easy for installation and maintenance.

（6）据工艺流程需要，经计算和试验确定适当的溢流管径和沉砂口径。

(6) According to the needs of process flow, appropriate diameter of overflow pipe and diameter of spigot are determined according to calculation and test.
