The pump mounting plates have several fixing options (Figure 1). Flexible hoses with internal diameters of 22mm (RS stock no. 266-597) or 13mm (RS stock no. 266-979) may be used (avoid overtightening as this may cause damage to the ports). The pump and pipework should be adequately supported and correctly fitted to avoid shock loading and strain on the pump and its ports. The pump should not be mounted vertically with the ports below the motor. 74 112 39 1.85 METRES 3 CORE CABLE C B B A 98 6 39 56 33 15.9 4 holes dia. 4.5 4 holes dia. 5.0 77 .8 10 4 F E D Figure 1 Dimensions RS stock numbers Dimensions 266-597 266-979 A 191 150 B 22 13 C 46 27.5 D 59 60 E 15 18.6 F 76 54.5 232-3440 Operation and maintenance The pump should have flooded suction since it does not self prime. Filters or restrictions should not be situated before the pump inlet. When priming, operate the pump in short 10 second cycles to facilitate the cleaning of air. Ensure that there are no leaks or blockages in the associated pipework. The pump should not be operated against a closed valve for longer than 30 seconds. Where the pumped fluid causes coating or deposition, periodic cleaning of pump internals may be necessary. This can be achieved by flushing through with an appropriate cleaning agent. The pump casing should be adequately ventilated to avoid overheating the motor. The motor is protected by the magnetic coupling should the impeller stall. Do not run pump dry.

Push the adapter up to the back of the panel ensuring that the controller is pushed all the way in, removing any gap between the Controller, panel, and adapter. Finally, use the two screws on the adapter to secure the unit in place. • To mount the E5GN so that it is waterproof, insert the waterproof packing onto the E5GN. • When two or more E5GN Controllers are mounted, make sure that the surrounding temperature does not exceed the allowable operating temperature given in the specifications. Group Mounted Mounting separately does not allow waterproofing. 22 Wiring Terminals • The voltage output (control output) is not electrically insulated from the internal circuits. When using a grounding thermocou- ple, do not connect the control output terminals to the ground. If the control output terminals are connected to the ground, errors will occur in the measured temperature values as a result of leakage current. • Standard insulation is applied to the power supply I/O sections. If reinforced insulation is required, connect the input and output terminals to a device without any exposed current-carrying parts or to a device with standard insulation suitable for the maximum operating voltage of the power supply I/O section.

Hay que diferenciar entre dos tipos constructivos básicos: Ventiladores radiales y ventiladores axiales. En los ventiladores axiales el aire fluye a través del ventilador en direc- ción axial. Estos ventiladores transportan cantidades grandes de aire (caudales) con pequeños aumentos de presión. Ventilador Axial Ventilador Radial Ventiladores industriales axiales Los ventiladores axiales son apropiados para la extracción de aire en general, ga- ses y vapores, o para la inyección de aire en recintos tales como salas de cine, tien- das, almacenes, establos, gallineros, etc. También se emplean para disipar el calor producido por equipos que requieran cons- tante refrigeración, como motores y trans- formadores de potencia. Extracción de aire Cuando se extrae aire de un local cerrado, se crea un vacío. Este vacío provoca la en- trada de aire fresco por las aberturas natu- rales del mismo (ventanas y puertas). En caso de que el local esté cerrado por com- pleto y haya que renovar el aire frecuente- mente, se hacen necesarias aberturas adi- cionales. La velocidad de aire entrante no deberá so- brepasar 1 m/s. En caso de locales gran- des, es preferible el uso de varios ventila- dores, porque una ventilación completa solamente existe cuando todo el aire del local es uniformemente removido. La extracción de aire se usa especialmente en lugares con concentraciones de gases, vapores y malos olores que no deban salir a locales vecinos. Inyección de aire En un local cerrado, el ventilador que in- troduce aire desde el exterior genera una leve sobrepresión y obliga al aire del local a salir por las aberturas naturales del mis- mo. Si el volumen de aire a renovar es grande, habrá que practicar aberturas adi- cionales para la salida del aire. La ventaja de esta modalidad de ventila- ción es poder limpiar el aire entrante por medio de filtros, o también acondicionarlo por medio de dispositivos adicionales. Combinación de sistemas Una combinación de sistemas de extrac- ción e inyección de aire es recomendable en los locales que requieran un elevado número de renovaciones de aire, o cuando se desee un flujo de éste en una dirección determinada. Instalaciones de extracción de impu- rezas del aire Son adecuadas para locales o fábricas don- de se generan vapores o polvo. Aparte de la ventilación del local, la extrac- ción de impurezas debe ser hecha lo más cerca posible del lugar donde se generan, por medio de un ventilador que, combina- do con un sistemas de campana y recolector, transporte las impurezas y las deposite (si es el caso) en lugares seguros (colectores). Dependiendo de las condiciones físicas y geométricas del local, es aconsejable insta- lar dos o más ventiladores uniformemente distribuidos, con lo cual se obtiene una ventilación más eficiente del recinto. Ya que el motor está dispuesto en el tra- yecto de flujo de aire, se recomienda utili- zarlo en temperaturas inferiores a 40º C., en la misma forma, para aplicaciones con humedad relativa alta del medio a trans- portar, se recomienda hacer protección IP54 al motor. Los ventiladores axiales con elevado caudal de aire son especialmente aptos para ser instalados sobre paredes o ductos, en cualquier posición axial. Para su montaje debe tenerse en cuenta la función de- seada: extracción o inyección, ya que el aire debe circu- lar en dirección de las aspas al motor, para lo cual el sentido de giro del motor debe ser hacia la derecha. Un cambio en el sentido de rotación reduce en un 35% el caudal nominal de aire. Su ejecución mecánica se basa en una tobera cilíndrica en lámina de acero (laminado en frío) con dos recubrimientos de pintura, una anticorrosiva, en casos de humedad, y otra de acabado color gris. El motor se fija por medio de cuatro soportes equi- distantes, un extremo apoyado sobre una abrazadera alrededor de este y el otro al cilindro del ventilador. La rueda de aletas plásticas, en polipropileno de alta resis- tencia o, bajo pedido, en fundición de aluminio, se fija directamente al eje del motor, no siendo necesaria una brida especial. Los valores de caudal de aire se basan en una sobre- presión estática equivalente a 0 N/m2 y en un medio a transportar con peso específico de 1.23 Kp/m, corres- pondiente al aire a una temperatura de 15º C. y 76 mm. columna de mercurio. Características técnicas Con motor monofásico Este tipo de ventilador se construye en diámetros desde 250 mm. hasta 500 mm., con motor sin interruptor centrífugo, es decir, con arranque por condensador para servicio permanente en redes de 110 V., 60 Hz. ó, bajo pedido, a 150 V., en ambos casos a 1800 rpm. El motor viene con carcasa en lámina de acero totalmen- te cerrado, protección IP44, con el condensador sobre el platillo posterior; de esta manera el aire circula libremen- te sin resistencias ni turbulencias a través de la superficie del motor, aumentando su caudal nominal y reduciendo el nivel de ruido. Con motor trifásico Este tipo de ventiladores se construye en diámetros des- de 400 mm. hasta 710 mm., con motores totalmente cerrados, clase de protección IP44, a 1800 y 1200 rpm., para redes de 220/440 V., 60 Hz, ó voltajes de 260 V. y 380 V., bajo pedido. Para la protección eléctrica del motor se aconseja utili- zar un guardamotor SIRIUS 3RV como protección con- tra cortocircuito, sobrecarga y marcha en dos fases, pro- ducidas por bajos voltajes o fallas en la red de alimenta- ción, adicionalmente permite la conexión y desco- nexión de la red.

Amplia gama de selección La selección de un ventilador se efectúa tomando en cuenta las condiciones de montaje y los datos característicos exigidos: caudal y sobrepresión. Determinación del caudal El caudal requerido para ventilar adecuadamente un local puede ser calculado, generalmente, en de- pendencia del volumen del local que debe ventilar- se y de la frecuencia de cambio de aire por hora, mediante la relación: Q = V x (R/h) 3600 Donde: Q = Caudal de aire requerido (m3/seg) V = Volumen del local a ventilar (m3) R/h = Número de renovaciones por hora En lugares donde se aglomeran personas, como ci- nes, teatros, colegios, comedores, discotecas, etc., se recomienda calcular el caudal de aire a remover con base en el aire necesario por persona/hora, tendiendo en cuenta el aire viciado (fumadores) y el calor producido por los cuerpos. Otro parámetro a considerar es la sobrepresión es- tática (la que vence las resistencias del sistema donde se encuentra el ventilador), ya que ella in- fluye sobre el caudal de aire. Para ventiladores instalados en locales (por ejem- plo cuando se montan en paredes), 20 a 50 Pa. aproximadamente, son suficientes. Si se conectan tuberías o aparatos para tratamiento de aire, hay que añadir la resistencia que producen. Los casos más comunes son: 1) Sin persianas ni filtros Sobrepresión estática: 0 N/m2 2) Con persianas pero sin filtros Sobrepresión estática: 10 a 30 N/m2 3) Con persianas y filtros Sobrepresión estática: 50 a 100 N/m2.

Ejemplo 1 Se pretende ventilar un taller de mecánica cuyo volumen es de 1800 m3. Para no contaminar el aire externo se ins- tala un filtro. La red disponible es trifásica de 220V. Renovaciones recomendadas 10 por hora. Caudal necesario: Q = 1800 m3 x 10 = 5.0 m3/s 3600 Debido al filtro, la sobrepresión estática será de 100 N/m2, por lo que se deberá seleccionar un ventilador tipo 2CC1 714, No. de Depósito 01189 cuyo caudal, a dicha presión, es de 7.8 m3/s. Para su protección se reco- mienda usar un guardamotor 3RV1021 4AA10, No. de Depósito 26873, regulado a la corriente nominal del mo- tor a 220 V., 14.0 A. Igualmente pueden ser utilizados dos ventiladores tipo 2CC2 504, cuyo caudal total es 2 x 2.4 m3/s. = 4.8 m3/s.
