Its advantages are mainly reflected in:
1. The speed is low, generally within 980r/min, which meets the requirements of the crystallization process and runs smoothly.2. Excellent hydraulic performance, efficiency >70%, wide efficient zone, and good anti-cavitation performance.3. Consider that the flow direction of the pump medium is vertically downward and horizontally out.The force of water flow has a huge impact on the pump shaft, so a pump shaft jacket protection device is added to the pump body.The subduction force of the medium is transferred to the pump body, thereby ensuring the stable operation of the pump, greatly reducing the impact of the medium on the mechanical seal force, and extending the service life of the machine seal.The improvement of this structure has taken a big step forward among similar domestic products.In addition, the pump body is made of integral casting with good rigidity, and the intermediate support structure is stably connected.4. The bearing box is a square long-span heavy-duty structure with good stability, strong load-bearing capacity and reliable operation. Compared with similar domestic products, it is easy and precise to install (the original domestic bearing box was split type).Radial short cylindrical bearings and heavy-duty paired bearings are used at the front and rear ends respectively.Its bearings all use NSK (SKF) or domestic high-quality bearings.5. The shaft seal is advanced, using a combination of auxiliary impeller dynamic seal and Burgman quick-install double-end mechanical seal, with external cooling and flushing water, which improves the working conditions of the shaft seal and has a long mechanical seal life.The outer circle of the shaft sleeve is enlarged, and the thickened wall deformation is smaller than that of similar domestic products.
