Identificar los cables sin marcar en los motores trifásicos es una tarea habitual para los técnicos de los centros de servicio. Este artículo presenta un método para asignar números a los cables de una máquina de 12 cables con los terminales sin marcar.

En el mundo de la maquinaria rotativa, términos como balanceo, holgura y alineación son habituales para ingenieros y técnicos. Pero hay un concepto que a menudo se esconde a simple vista, crucial para el rendimiento, la longevidad y la seguridad: la alineación del centro magnético.

No importa donde opere en el mundo, la respuesta más común a los desafíos parece ser redactar una nueva norma, directriz o marco regulatorio. El resultado suele ser un sistema de calidad que se convierte en una montaña de documentos, procedimientos y procesos, cada uno concebido para garantizar la calidad, pero que en conjunto amenaza con agobiar tanto a los tall-eres como a los ingenieros.

Identifying unmarked leads in three-phase motors is a common task for service center technicians. This article provides one way to assign lead numbers for a 12-lead machine with unmarked leads.

Have you ever been out at a restaurant or sports bar to meet up with some friends and colleagues to have an adult beverage or two when suddenly someone leans on the table ever so slightly and liquid spills everywhere? What just happened? The small space between the table leg and the floor has just created a big consequence. While it’s not too difficult to solve if you have some napkins and a few coasters, it does, however, illustrate the results of a soft foot and how a very small space can lead to a much larger consequence.

No matter where you operate in the world, the most common response to challenges seems to be drafting a new standard, guideline or regulatory framework. The outcome is often a quality system that grows into mountains of documents, procedures and processes—each one intended to ensure quality, but collectively threatening to overwhelm both workshops and engineers.

In the world of rotating machinery, terms like balance, clearance and alignment are second nature to engineers and technicians. But one concept often hides in plain sight—critical to performance, longevity and safety—magnetic center alignment.

This presentation focuses on the proper clearances, materials and installation process for centrifugal pump wear rings.

Equipping a pump test facility for variable speed operation can provide greater flexibility and expand opportunities to evaluate pump performance.

Emplear velocidad variable durante las pruebas puede brindar mayor flexibilidad y ampliar las oportunidades para evaluar el rendimiento de las bombas.
