1、本產品系按中華人民共和國行業標準DZ/T0194-1997《聚氨酯水力旋流器》制造、安裝、檢測。

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、本產品具有如下結構參數；詳見附頁。

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

3、水力旋流器結構特點：

3. Structural Features of Hydro-cyclone:

（1）產品用聚氨酯彈性體材料制作內襯，具有耐磨性強，重量輕，不為酸、堿、鹽溶液腐蝕，不易老化，不發生銹蝕等優點。但不應在大于80℃時工作。

(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）本產品適用于含固體泥漿（包括低黏度溶液）的顆粒分級、濃縮、脫泥及水質凈化作業，可用于選礦廠的閉路磨礦分級，尾砂輸送或用于井下充填、筑壩時的尾礦濃縮，非金屬礦及化工原料的粉體制備，油田鉆井泥漿的除 凈化，環保廢水處理等作業。

(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）聚氨酯由模具澆柱而成，因此內部幾何形狀尺寸準確，內表面非常光滑。

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

（4）給料口的形狀采用螺旋線進料或漸開線進料，因此進料過程中能獲得預分離作用，提高分離效率。

(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）合理的流道結構、光滑的內表面，盡可能少的泄露點等，使得水力旋流器凈化效果好，安裝簡單，維修方便。

(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）據工藝流程需要，經計算和試驗確定適當的溢流管徑和沉砂口徑。

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