DESCRIPCIONDESCRIPTION
Sistema equipado con unidad de bombeo de presion variable y baja tasa de flujo, en particular para la limpiezaSystem equipped with variable pressure pumping unit and low flow rate, in particular for cleaning
La presente invencion se refiere a un sistema equipado con una unidad de bombeo de presion variable y de baja tasa de flujo. A continuacion se describira aqu la invencion con referencia a un sistema de limpieza, pero que se podra utilizar, de una manera igualmente eficiente, en campos similares, pero tambien diferentes, tales como limpieza industrial, actividades de eliminacion de materiales, pinturas, etc., como se describe a continuacion.The present invention relates to a system equipped with a variable pressure and low flow rate pumping unit. Next, the invention will be described here with reference to a cleaning system, but which can be used, in an equally efficient manner, in similar, but also different fields, such as industrial cleaning, material removal activities, paints, etc. , as described below.
Se conocen en la tecnica diversos sistemas de limpieza que utilizan agua a presion variable, por ejemplo para lavar tubenas, reactores, suelos, maquinaria, plantas de pintura, tanques y similares. Las unidades de bombeo y los sistemas de presion variable disponibles en el mercado tienen el proposito de explotar toda la potencia provista por la bomba de presion variable, tanto en terminos de presion como en tasa de flujo. Ademas, el agua a presion variable no permite el uso de acidos o solventes para la limpieza, con los consecuentes beneficios ambientales y economicos.Various cleaning systems that use variable pressure water are known in the art, for example for washing tubenas, reactors, floors, machinery, paint plants, tanks and the like. The pumping units and the variable pressure systems available on the market are intended to exploit all the power provided by the variable pressure pump, both in terms of pressure and flow rate. In addition, variable pressure water does not allow the use of acids or solvents for cleaning, with the consequent environmental and economic benefits.
Estos sistemas, sin embargo, no son satisfactorios y tienen, entre otras cosas, el problema de tener que utilizar presiones de funcionamiento no muy altas, incluidas entre 80 y 200 bar, y altas tasas de flujo de agua, incluidas entre 30 y 90 litros/minuto: tales condiciones son serias dificultades para un operador responsable de la limpieza, forzado a operar con chorros violentos y salpicaduras apenas controladas de agua a presion variable.These systems, however, are not satisfactory and have, among other things, the problem of having to use not very high operating pressures, including between 80 and 200 bar, and high water flow rates, including between 30 and 90 liters / minute: such conditions are serious difficulties for an operator responsible for cleaning, forced to operate with violent jets and barely controlled splashes of water at variable pressure.
Se conocen ademas sistemas de alta presion, que sin embargo requieren explotar toda la potencia suministrada por la bomba de alta presion, tanto en presion como en tasa de flujo.High pressure systems are also known, which nevertheless require exploiting all the power supplied by the high pressure pump, both in pressure and in flow rate.
