Performance curves are among the most crucial and frequently requested documents from fan manufacturers, second only to dimensional prints. While many request these documents, not everyone fully understands their significance or maximizes their potential.
Las curvas de rendimiento se encuentran entre los documentos más importantes y solicitados a los fabricantes de ventiladores, superadas únicamente por los planos dimensionales. Si bien muchos solicitan esta documentación, no todos comprenden plenamente su importancia ni aprovechan al máximo su potencial.
The purpose of this article is to explain the basis and application of rules used to “estimate” fan performance for a fan installed in a duct system moving air when the speed of the fan is changed.
El propósito de este artículo es explicar los fundamentos y la aplicación de las reglas utilizadas para estimar el rendimiento de un ventilador instalado en un sistema de conductos que mueve aire al variar su velocidad. Con un conocimiento básico de estas reglas, es posible calcular rápidamente el rendimiento de un ventilador para diversas condiciones de velocidad.
Dirigida principalmente al personal del centro de servicio, la guía, que ahora es un documento independiente y no forma parte del informe completo del estudio de rebobinado de EASA/AEMT, describe los métodos de reparación de buenas prácticas utilizados para lograr los resultados proporcionados en ambos estudios. Contiene consejos de reparación, terminología relevante del motor e información sobre fuentes de pérdidas en motores de inducción que afectan la eficiencia.
En toda reparación mecánica, la capacidad para desmontar, reparar y volver a montar el motor de forma apropiada sin dañar innecesariamente ninguna de sus piezas es fundamental.
Esta obra contiene muchas sugerencias sobre el manejo apropiado de las diferentes partes de un motor para minimizar los daños durante el proceso de reparación. Sin embargo, es imposible desarrollar un listado que las incluya todas.
En cambio, el principio básico de tomarse el tiempo para usar la herramienta adecuada y por lo general el procedimiento apropiado guiará a los técnicos por el camino correcto.
Determining the source of noise in a motor is often much more challenging than correcting it. However, a methodical approach to investigating the noise can narrow down the possible causes.
Intended primarily for service center personnel, the guide which is now an independent document and not part of the complete EASA/AEMT rewind study report, outlines the good practice repair methods used to achieve the results given in both studies. It contains repair tips, relevant motor terminology, and information about sources of losses in induction motors that affect efficiency.
