Frenquently asked questions and answers of centrifugal pumps

The stainless steel multi-stage pump has been working for a long time. Due to the reasons such as loose water seal, air in the pump body, motor reversal, impeller flow channel blockage, etc., the water pump suction is insufficient, which greatly affects the production efficiency of the water pump. Our factory has summarized the reasons and solutions for the insufficient suction of the stainless steel multi-stage pump. The following is a detailed introduction.

Understanding pump curves is fundamental for effective fluid mechanics and the efficient operation of fluid transfer systems. A pump curve acts as a performance report, visually outlining a pump's behavior under various conditions. Key elements include the Head-Flow (H-Q) curve, illustrating the relationship between flow rate (x-axis) and head (y-axis), supplemented by data on efficiency, brake horsepower (BHP), and Net Positive Suction Head Required (NPSHr). This graphical representation is cru

The article focuses on centrifugal pumps. It systematically covers a basic working principle, classification, key parameters and model interpretation, elaborates on daily operation specifications and core maintenance measures, sorts out common faults like cavitation, vapor erosion and bearing housing overheating, explains structural design key points, axial force balancing methods, transmission connection types and normal operation criteria.
