Selection Principles For Slurry Pumps And Motors

The selection principles for slurry pumps and motors are very important It is mainly to determine the model specifications, type and the model, specifications and type of the motor to be used The selection of pumps and motors should follow the following principles: 1. Meet performance requirements: The performance of the pump mainly refers to the flow rate, head, and cavitation margin of the pump, followed by the speed, power and efficiency of the pump The flow rate and head of the pump are often valued by people, but the cavitation margin of the pump is often ignored In fact, when the cavitation of the pump is not met It will reduce the performance of the pump and shorten its life, and it will be unusable in severe cases 2. Meet process and installation requirements: In addition to the above performance requirements, the process requirements must also meet the temperature, properties, viscosity, corrosiveness and Containing impurities, etc. At the same time, the requirements for installation must also be considered 3. Economic efficiency: It is necessary to consider the economic efficiency of both one-time investment and long-term use costs One-time investment refers to the cost of purchasing pumps, motors, pipelines and the construction investment of pump stations Long-term use economy considers power consumption and pipeline hydraulic loss The life and maintenance cost of pumps and motors 4. Convenient installation, use, maintenance and repair of pumps The above are the selection principles of slurry pumps and motors Whether the selection is correct or not directly affects whether the pump meets the use requirements, is economical and easy to use If the selection is inappropriate, it will cause uneconomical operation and convenient use and maintenance Short life, high purchase cost, or even unusable So the selection of pumps and motors is an important task
