Owns 8 patent technologies, the comprehensive performance of ZW axial flow pump ranks in top among all the local competitors in China. It is a product of provincial achievement ,and it gained the award of technology progress of China machinery industry. There are plenty of real sales achievements for every single specification from diameter 250 mm to 1500 mm. ZW axial flow pump is widely used as forced circulation pump in the applications of big flow rate with low total head,for example: MVR water treatment, vacuum salt, aluminum oxide, sodium sulfate, chlorine-alkali, sugar making,seawater desalination..

From the perspective of the displacement direction of conveying materials, screw conveyors are divided into two types: horizontal screw conveyors and vertical screw conveyors. They are mainly used for horizontal conveying of various powder, granular and small pieces of loose materials. And vertical lifting, this machine is not suitable for conveying special materials that are easily deteriorated, viscous, easy to agglomerate or high temperature, afraid of pressure, and highly corrosive.
The screw conveyor has the advantages of simple structure, low production cost, strong sealing, safe and convenient operation, etc. It can be loaded and unloaded at multiple points in the middle. It is widely used in chemical, building materials, metallurgy, grain and other departments. When the inclination angle is β<20°, it can transport powdery, granular and small pieces of materials that are not viscous, not easy to deteriorate, and not easy to agglomerate.
The characteristics of the screw conveyor are: simple structure, small cross-sectional size, good sealing, reliable operation, low production cost, convenient intermediate loading and unloading, and the conveying direction can be reversed or conveyed in opposite directions. During the process, the materials can also be stirred, mixed, heated and cooled. The material flow can be adjusted through the loading and unloading gate. However, it is not suitable to convey materials that are perishable, viscous, easy to agglomerate and bulky. During the conveying process, the material is easily broken, and the screw and the trough are easily worn.
