What are the structural characteristics of forced circulation pumps? Today, our editor from Shanhe Pump Industry will explain to you: The forced circulation pump has a low speed, generally within 980r/min, which meets the requirements of the crystallization process and runs smoothly. Excellent hydraulic performance, efficiency 〉70%, wide high-efficiency zone, and good anti-cavitation performance. Considering that the flow direction of the pump medium is vertically downward and horizontally out. Due to the huge impact of the water flow force on the pump shaft, a pump shaft jacket protection device is added to the pump body.
The diving 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 adopts integral casting with good rigidity and stable connection of the intermediate support structure. The horizontal axial flow pump has no guide vanes. The bearing box of the forced circulation pump is a square long-span heavy-duty structure with good stability, strong bearing capacity, reliable operation, and easy installation compared with similar domestic products (the original domestic bearing box is split). The front and rear ends use short radial cylindrical bearings and heavy-duty paired bearings respectively. The bearings are all NSK (SKF) or domestic high-quality bearings.
The forced circulation pump has an advanced seal shaft, which uses a combination of auxiliary impeller dynamic seal and Burgman quick-install double-end mechanical seal, external cooling and flushing water, improves the working conditions of the shaft seal, and prolongs the service life of the mechanical seal. The outer diameter of the sleeve is enlarged, and the wall thickness is thicker and the deformation is small compared with similar domestic products. Then, I will introduce the structural characteristics of the forced circulation pump to you here, and I hope it will be of some help to you.
