“Sistema dotato di unità pompante ad alta pressione e bassa portata, in particolare per pulizie†⠀ œSystem equipped with high pressure and low flow pumping unit, especially for cleaningâ €
DESCRIZIONE DESCRIPTION
La presente invenzione si riferisce ad un sistema dotato di unità pompante ad alta pressione e bassa portata. Qui di seguito l'invenzione sarà descritta facendo riferimento ad un sistema per pulizie, ma essa potrà essere impiegata, in modo ugualmente efficace in campi simili, ma anche differenti, quali pulizie industriali, attività di rimozione di materiali, sverniciature, ecc., come più avanti indicato. The present invention refers to a system equipped with a high pressure, low flow rate pumping unit. Hereinafter the invention will be described with reference to a cleaning system, but it can be used equally effectively in similar but also different fields, such as industrial cleaning, material removal activities, paint stripping, etc., such as further indicated.
Sono noti nella tecnica vari sistemi di pulizia che utilizzano acqua ad alta pressione, ad esempio per il lavaggio di tubazioni, reattori, pavimentazioni, macchinari, impianti di verniciatura, serbatoi e simili. Le unità pompanti ed i sistemi ad alta pressione disponibili sul mercato hanno lo scopo di sfruttare tutta la potenza fornita dalla pompa ad alta pressione, sia in termini di pressione che di portata. Inoltre, l'acqua ad alta pressione consente di non utilizzare acidi o solventi per le pulizie, con un conseguente beneficio ambientale ed economico. Various cleaning systems are known in the art which use high pressure water, for example for washing pipes, reactors, floors, machinery, painting systems, tanks and the like. The pumping units and high pressure systems available on the market have the purpose of exploiting all the power supplied by the high pressure pump, both in terms of pressure and flow rate. Furthermore, the high-pressure water makes it possible to avoid the use of acids or solvents for cleaning, with a consequent environmental and economic benefit.
Questi sistemi tuttavia non sono soddisfacenti e presentano, tra l'altro, il problema di dover impiegare pressioni di esercizio non molto alte, comprese tra 80 e 200 bar, ed elevate portate d'acqua, comprese tra 30 e 90 litri al minuto: tali condizioni mettono in seria difficoltà l'operatore addetto alla pulizia, costretto a dover operare con getti violenti e schizzi poco controllabili di acqua ad alta pressione. However, these systems are not satisfactory and present, among other things, the problem of having to use not very high operating pressures, between 80 and 200 bar, and high water flow rates, between 30 and 90 liters per minute. conditions put the cleaning operator in serious difficulty, forced to work with violent jets and uncontrollable splashes of high pressure water.
Scopo della presente invenzione à ̈ risolvere i suddetti problemi della tecnica anteriore, fornendo un sistema dotato di unità pompante ad alta pressione e bassa portata, che consenta di realizzare le seguenti migliorie: The purpose of the present invention is to solve the aforementioned problems of the prior art by providing a system equipped with a high pressure, low flow rate pumping unit, which allows the following improvements to be made:
- utilizzare la minima portata di acqua necessaria all’esecuzione di pulizie industriali, attività di rimozione di materiali, sverniciature, ecc. (2-4 l/min) così da ridurre al minimo l’impatto ambientale sia energetico sia di generazione del rifiuto (acqua contaminata a seguito del suo utilizzo); - use the minimum water flow rate necessary for industrial cleaning, material removal activities, paint stripping, etc. (2-4 l / min) in order to reduce to a minimum the environmental impact, both energy and waste generation (water contaminated as a result of its use);
- utilizzare un campo di pressione variabile, tale da poter rendere l’unità pompante flessibile come caratteristiche di impiego (da 500 a 2.500 bar); - use a variable pressure range, such as to make the pumping unit flexible in terms of use (from 500 to 2,500 bar);
- poter essere facilmente trasportata su un furgone o analogo mezzo di trasporto piccolo e maneggevole; - can be easily transported on a small and handy van or similar means of transport;
- poter essere facilmente movimentata sul luogo di lavoro mediante l’impiego di ruote fisse o girevoli; - can be easily handled in the workplace by using fixed or swivel wheels;
- poter essere facilmente impiegabile sul luogo di lavoro, cioà ̈ non dover necessitare di tanti allacciamenti per il funzionamento. - be able to be easily used in the workplace, that is, not having to need many connections for operation.
I suddetti ed altri scopi e vantaggi dell’invenzione, quali risulteranno dal seguito della descrizione, vengono raggiunti con un sistema dotato di unità pompante ad alta pressione e bassa portata come descritto nella rivendicazione 1. Forme di realizzazione preferite e varianti non banali della presente invenzione formano l’oggetto delle rivendicazioni dipendenti. The above and other objects and advantages of the invention, as will emerge from the following description, are achieved with a system equipped with a high pressure and low flow rate pumping unit as described in claim 1. Preferred embodiments and non-trivial variants of the present invention form the subject of the dependent claims.
Resta inteso che tutte le rivendicazioni allegate formano parte integrante della presente descrizione. It is understood that all the attached claims form an integral part of the present description.
La presente invenzione verrà meglio descritta da alcune forme preferite di realizzazione, fornite a titolo esemplificativo e non limitativo, con riferimento ai disegni allegati, nei quali l'unica Figura 1 à ̈ uno schema a blocchi schematico di una realizzazione preferita del sistema dotato di unità pompante della presente invenzione. The present invention will be better described by some preferred embodiments, provided by way of non-limiting example, with reference to the attached drawings, in which the only Figure 1 is a schematic block diagram of a preferred embodiment of the system equipped with units pumping element of the present invention.
Facendo riferimento alla Figura 1, à ̈ illustrata e descritta una forma di realizzazione preferita del sistema della presente invenzione. Risulterà immediatamente ovvio che si potranno apportare a quanto descritto innumerevoli varianti e modifiche (per esempio relative a forma, dimensioni, disposizioni e parti con funzionalità equivalenti) senza discostarsi dal campo di protezione dell'invenzione come appare dalle rivendicazioni allegate. Referring to Figure 1, a preferred embodiment of the system of the present invention is illustrated and described. It will be immediately obvious that innumerable variations and modifications (for example relating to shape, dimensions, arrangements and parts with equivalent functionality) can be made to what has been described without departing from the scope of the invention as appears from the attached claims.
Pertanto, per realizzare il sistema inventivo e per raggiungere gli scopi sopra prefissati, si à ̈ proceduto ad assemblare una serie di componenti già disponibili sul mercato in modo da ottimizzare le prestazioni, gli ingombri, e gli allacciamenti energetici ed idraulici. Therefore, in order to realize the inventive system and to achieve the aforementioned purposes, we proceeded to assemble a series of components already available on the market in order to optimize the performances, the overall dimensions, and the energy and hydraulic connections.
A differenza dei sistemi noti con unità pompante ad alta pressione, il sistema secondo la presente invenzione ha lo scopo di fornire le prestazioni minime per effettuare le lavorazioni (pulizie industriali, attività di rimozione di materiali, sverniciature, ecc.) in modo da utilizzare la minore quantità di acqua possibile; in questo si concentra l’innovazione introdotta dall’unità pompante in oggetto, che à ̈ stata concepita e progettata in modo da ottimizzare questo scopo. Unlike the known systems with high pressure pumping unit, the system according to the present invention has the purpose of providing the minimum performances for carrying out the workings (industrial cleaning, material removal activities, paint stripping, etc.) in order to use the as little water as possible; this is where the innovation introduced by the pumping unit in question is concentrated, which has been conceived and designed in order to optimize this purpose.
Il sistema inventivo comprende pertanto: The inventive system therefore includes:
- almeno un'unità pompante (pompa) ad alta pressione 1 atta a pompare con elevata pressione di uscita acqua o altri fluidi analoghi; - at least one high pressure pumping unit (pump) 1 suitable for pumping water or other similar fluids with high outlet pressure;
- almeno un motore elettrico 3 collegato alla pompa ad alta pressione 1; ed - at least one electric motor 3 connected to the high pressure pump 1; and
- almeno un dispositivo 5 di regolazione dei giri della pompa 1 (in particolare un inverter), collegato al motore 3 per il suo comando. - at least one device 5 for regulating the revolutions of the pump 1 (in particular an inverter), connected to the motor 3 for its control.
Come possibili varianti e alternative, l'unità pompante dell'invenzione può comprendere inoltre: - almeno un compressore aria 7 collegato alla pompa ad alta pressione 1; As possible variants and alternatives, the pumping unit of the invention can further comprise: - at least one air compressor 7 connected to the high pressure pump 1;
- almeno un sistema 9 di filtraggio dell'acqua, collegato ad almeno un serbatoio 11 per l'acqua, a sua volta collegato ad almeno una elettropompa booster 13, collegata alla pompa ad alta pressione 1; e - at least one water filtering system 9, connected to at least one water tank 11, in turn connected to at least one booster electric pump 13, connected to the high pressure pump 1; And
- almeno un ugello 15, speciale per bassa portata, dal diamtro di uscita preferibilmente pari a 0,4 mm. - at least one nozzle 15, special for low flow rates, with an outlet diameter preferably equal to 0.4 mm.
La pompa ad alta pressione 1 Ã ̈ collegata al motore elettrico 3 mediante un sistema di accoppiamento che trasmette il moto. The high pressure pump 1 is connected to the electric motor 3 by means of a coupling system which transmits the motion.
Il motore elettrico 3 à ̈ comandato mediante un quadro elettrico (non illustrato) che include l'inverter 5 allo scopo di poter variare i giri della pompa ad alta pressione 1 e quindi la sua portata; i giri del motore 3 sono regolati dall’operatore in funzione del valore di pressione da adottare e del consumo di acqua da ottenere. The electric motor 3 is controlled by means of an electric panel (not shown) which includes the inverter 5 in order to be able to vary the revolutions of the high pressure pump 1 and therefore its flow rate; the revolutions of the motor 3 are regulated by the operator according to the pressure value to be adopted and the water consumption to be obtained.
L’acqua di alimentazione alla pompa ad alta pressione 1 viene fatta passare attraverso un sistema filtrante 9 e quindi viene immagazzinata nel serbatoio di accumulo 11; l'elettropompa booster 13 consente di inviare l’acqua all’ingresso della pompa ad alta pressione 1. The feed water to the high pressure pump 1 is passed through a filtering system 9 and is then stored in the accumulation tank 11; the electric booster pump 13 allows water to be sent to the inlet of the high pressure pump 1.
La pompa ad alta pressione 1 à ̈ dotata inoltre di una valvola di controllo (non illustrata) che può essere attuata sia elettricamente che pneumaticamente; ed il compressore dell’aria 7 provvede a fornire l’aria compressa necessaria. The high pressure pump 1 is also equipped with a control valve (not shown) which can be actuated both electrically and pneumatically; and the air compressor 7 supplies the necessary compressed air.
L’acqua ad alta pressione viene inviata all'ugello speciale 15, appositamente studiato per generare un flusso a bassa portata con un diametro di 0,4 mm. The high pressure water is sent to the special nozzle 15, specially designed to generate a low flow rate with a diameter of 0.4 mm.
L'aspetto innovativo dell'unità pompante sopra descritta consiste nel realizzare la pompa ad alta pressione 1 in modo che eroghi la massima pressione possibile con una portata molto bassa ed una dimensione ridotta, soluzione realizzabile utilizzando l'inverter 5 connesso al motore elettrico 3, anch'esso di piccole dimensioni. The innovative aspect of the pumping unit described above consists in realizing the high pressure pump 1 so that it delivers the maximum possible pressure with a very low flow rate and a reduced size, a solution that can be achieved using the inverter 5 connected to the electric motor 3, also small in size.
Il sistema sopra descritto, nella sua forma attualmente preferita, ma assolutamente non limitativa, presenta le seguenti caratteristiche generali: The system described above, in its currently preferred but absolutely non-limiting form, has the following general characteristics:
