Need a speed versus torque curve? Get one from Centrix with dampers open or closed.Д¬entrix enables the user of the software to interact with the program and mechanically design the fan. Centrix gives a warning when the critical speed is below 35% margin.Д®ver had a start up problem? Centrix calculates the starting time and gives warnings alerting you to investigate the use of a larger motor or higher staring torque. The shaft critical speed should always be higher than the fan running speed by a margin of at least 25%. Did you know that in overhung fans (arrangements 1, 2, 8, 9) the shorter the distance between the bearings the higher the critical speed is and the larger the impeller overhang from the inboard bearing the lower the critical speed is. If you have ever been unable to balance a fan in service and it vibrates like crazy then you probably have a shaft critical speed problem. Shaft critical speed is easily calculated by Centrix. Also Arrangement 7 shaft and bearings can often be used when an arrangement 8 shaft can't. However the same fan could be direct coupled arrangement 8 with no problems due to the much lower load. For example a particular fan selection may not be suitable for belt drive because the bearings can't take the load and larger bearings can't be used because of rpm limitations. A single aerodynamic design can meet any volume and pressure that you can think of but the size or speed may not be practical due to mechanical limitations (size outside the range or speed outside the range).ДЄ) Impeller stresses - dependent on speed, temperature, thickness and material selection.Д«) Casing thickness - dependent upon fan diameter, pressure and noise breakout.Д¬) Shaft design - dependent upon impeller weight, belt or coupling load, motor torque, fan arrangement, temperature etc.Д) Bearing selection - dependent on shaft size and loads and rpm.Д¬) Pedestal design - dependent on fan diameter, power and rpm.Д¬entrix selects a standard size of aerodynamic design and calculates all the above factors (and more). The aerodynamic design is what gives a particular fan its volume, pressure and power characteristics. H & R Resources can provide fan aerodynamic design criteria if required. These designs are usually provided by the purchaser. Screenshots Click For Large ImageДЄerodynamic designs and a nominal range of sizes are entered into the program by H & R Resources. Centrix uses these proportions and designs a range of fans by manipulating the fan laws. The aerodynamic proportions must be known and entered into the Centrix database. Produces a handing specific General Arrangement drawing. Produces Autocad cutting profiles for the main components.Д®stimates the costs, areas, weights and labour hours. Produces detail and arrangement drawings.ДЄutomated Drawings generation saved as Autocad dwg files. Mechanically designs and calculates stresses. Selects fans from a range of designs to suit a volume and pressure. This program does in a couple of minutes what an experienced fan engineer would take many hours to design and cost!
