Abstract

Inventia se refera la un dispozitiv pentru protectia filtrelor de înalta presiune la socuri hidraulice sau caderi mari de presiune pe filtru, care sesizeaza prin închiderea sau deschiderea unui circuit electric momentul colmatarii filtrului si nu permite cresterea caderii de presiune pe filtru peste o anumita valoare protejînd astfel elementul filtrant. Inventia prezinta urmatoarele avantaje: este o constructie simpla, cu un numar mic de piesa sesizeaza colmatarea si limiteaza caderea de presiune pe filtru, are posibilitatea reglarii simultane a caderilor de presiune pe filtru; are posibilitatea reglarii simultane a caderilor de presiune la care se sesizeaza colmatarea cu caderile de presiune la care fluidul ocoleste filtrul; se poate utiliza la presiuni înalte si are rezistenta mare la socuri.The invention relates to a device for the protection of high pressure filters against hydraulic shocks or large pressure drops on the filter which senses by closing or opening an electric circuit the moment of filtering the filter and does not allow the increase of the pressure drop on the filter over a certain value thus protecting the filter element. The invention has the following advantages: it is a simple construction, with a small number of parts, senses the clogging and limits the pressure drop on the filter, it has the possibility of simultaneously adjusting the pressure drops on the filter; has the possibility of simultaneously adjusting the pressure drops at which the clogging with the pressure drops at which the fluid passes through the filter; it can be used at high pressures and has high shock resistance.
