  • Article rating: 4.2
Article

Submersible pumps may have any of several types of internal sensors or protective devices. These may include temperature sensors, vibration transducers or moisture sensors. The type of temperature and vibration devices are identical to those used in non-submersible style motors, so only the moisture sensors are of special interest regarding submersible pumps. It is important for technicians involved in the repair of submersible pumps to be aware of their presence in any specific pump they may encounter, and understand the manner in which they function to ensure they work properly after repairs are completed.

Uso de sensores de humedad en bombas sumergibles

  • Article rating: 4.5
Article

Las bombas sumergibles pueden tener diferentes tipos de sensores o dispositivos de protección internos, los cuales pueden ser sensores de temperatura, transductores de vibración o sensores de humedad. Los sensores de temperatura y de vibración son idénticos a los utilizados en los motores no sumergibles, por lo que solo los sensores de humedad guardan especial relación con las bombas sumergibles. Es importante que los técnicos involucrados en la reparación de las bombas sumergibles sean conscientes de su presencia en cualquier bomba en los que se puedan encontrar y que comprendan como trabajan para asegurarse que funcionan correctamente después de terminar los trabajos de reparación.

A closer look: Winding protection device can prevent permanent damage to motor

  • March 2002
  • Number of views: 7449
  • Article rating: 4.5
Article

There are a number of different types of winding protection devices used with motors. However, they all basically do the same thing; they sense a change from the normal operating temperature and either sound an alarm or take the motor off line when the specified temperature limit has been met or exceeded. Temperature protection is not limited to just large motors. A smaller motor that is critical to operation would be a good candidate for winding temperature protection if a failure would cause significant costs due to downtime.
