Dealing with wet/flooded motors

Recovering from disaster: Saltwater becomes a major problem

Flooding in the aftermath of tropical storms (hurricanes, monsoons and cyclones) with heavy rainfall will often shut down hundreds of plants along the Gulf Coast from Florida to Texas and other places around the world. To get them up and running again, maintenance departments and motor repairers face the daunting task of cleaning muck and moisture from many thousands of electric motors and generators. The process in such situations can take weeks, if not months, and requires special clean-up procedures for motors contaminated by saltwater.

A menudo, las inundaciones producidas por las intensas lluvias de las tormentas tropicales (huracanes, monzones y ciclones) colapsan cientos de plantas industriales a todo lo largo de la costa del golfo de México, desde la Florida hasta Texas y en otros lugares del mundo. Para retomar las actividades productivas, los departamentos de mantenimiento y los reparadores enfrentan la difícil tarea de limpiar la suciedad y desalojar la humedad en miles de motores y generadores eléctricos. El proceso en tales situaciones puede tomar semanas o meses y requiere procedimientos especiales para limpiar los motores contaminados con agua salada.

Es bien conocido por aquellos que trabajan con el almacenamiento de motores eléctricos que las filosofías y procedimientos de mantenimiento varían. La revisión minuciosa de la información de EASA y siete fabricantes de motores diferentes sobre el almacenamiento de motores reveló algunas diferencias y similitudes interesantes en la información disponible en cada una de las fuentes consultadas.

Varias fuentes comparten elementos comunes como el ambiente, la protección contra humedad, el mantenimiento de los rodamientos y la resistencia de aislamiento. Aquí, la finalidad de nuestro debate es describir algunas de las diferencias y ojalá dar a conocer algunos puntos a tener en cuenta cuando se crea un procedimiento de almacenamiento a largo plazo para los usuarios finales.

Form/Worksheet

Paperwork.  No one likes it on the shop floor. Nobody wants to fill out forms.

Like most service centers, Stewart's Electric Motor Works recognized that accurate paperwork is a necessary part of any effective system for achieving product quality. But it was their experience that it’s always difficult to develop easy-to-use forms that will streamline the process of moving jobs through the shop. With those thoughts in mind, they set out to find a better way to create user-friendly forms.

At Rapa Electric, we’ve had a number of “opportunities” to remove a blind pinion from a motor shaft. Sometimes, if we’re lucky, the pinion may have a push-off bolt to facilitate removal. And at other times, there may be a through-hole in the rotor shaft so that we can use a push-bar to shove the pinion out of its hole. If we’re not so lucky, we have to use a more creative method.
