A menudo se sustituye una bomba hidr\u00e1ulica ruidosa antes de que nadie compruebe las condiciones de su entrada. Si la bomba no recibe suficiente aceite a la presi\u00f3n de entrada necesaria, pueden formarse cavidades de vapor y colapsar en su interior. Esto puede provocar ruido y da\u00f1os. El aire que entra a trav\u00e9s de una conexi\u00f3n de succi\u00f3n mal ajustada puede producir s\u00edntomas similares, por lo que el ruido por s\u00ed solo no prueba que haya cavitaci\u00f3n.<\/p>\n

Medir en la entrada de la bomba<\/h2>\n

Start with the pump manufacturer’s permitted inlet-pressure range at the relevant speed and fluid viscosity. Measure pressure or vacuum as close to the inlet port as the service procedure allows. Compare cold start, normal operation and the highest-flow phase. Bosch Rexroth emphasizes that acceptable suction pressure depends on the specific pump and that line diameter, length, lift and oil viscosity all affect inlet resistance.<\/p>\n

Revisa todo el recorrido de succi\u00f3n<\/h2>\n

Compruebe el nivel m\u00ednimo de aceite en el dep\u00f3sito, si hay filtros obstruidos, si la manguera de aspiraci\u00f3n est\u00e1 colapsada, si hay demasiados codos, si la tuber\u00eda es de secci\u00f3n insuficiente y si el dep\u00f3sito est\u00e1 situado muy por debajo o lejos de la bomba. El aceite fr\u00edo tiene una viscosidad mayor y puede aumentar considerablemente la p\u00e9rdida de presi\u00f3n. HYDAC advierte de que los elementos de aspiraci\u00f3n deben permanecer por debajo del nivel m\u00ednimo de aceite y que una alta viscosidad en el arranque en fr\u00edo puede aumentar la ca\u00edda de presi\u00f3n a trav\u00e9s de un filtro.<\/p>\n

Distinguir entre cavitaci\u00f3n y entrada de aire<\/h2>\n

A leaking joint on a suction line may admit air without leaking much oil outward. Inspect seals, fittings and hose condition and look for persistent foam or milky oil in the reservoir. Flowing air bubbles and vapor cavities require different corrective actions. Also consider mechanical coupling faults and valve chatter when interpreting noise. If damage is suspected, follow the pump manufacturer’s inspection procedure rather than continuing to run a starved unit.<\/p>\n

Una orden de correcci\u00f3n razonable<\/h2>\n
    \n
  1. Anota la presi\u00f3n de entrada, la velocidad, la temperatura del aceite y el caudal de funcionamiento.<\/li>\n
  2. Comprueba el nivel de aceite y revisa el estado del conducto de aspiraci\u00f3n.<\/li>\n
  3. Compara las p\u00e9rdidas en las tuber\u00edas, mangueras y filtros instalados con los datos de la bomba.<\/li>\n
  4. Corregir las restricciones o las fugas de aire y, a continuaci\u00f3n, repetir las mediciones en las mismas condiciones de funcionamiento.<\/li>\n
  5. Si los s\u00edntomas persisten, comprueba el estado de la bomba y la limpieza del aceite.<\/li>\n<\/ol>\n

    Nuestro Gu\u00eda sobre la limpieza del aceite<\/a> abarca los objetivos de filtraci\u00f3n; nuestro Gu\u00eda de tallas de HPU<\/a> helps document the demand on the pump. Final diagnosis requires measurements and the selected pump’s limits.<\/p>\n
