DESCRIZIONE DESCRIPTION
“TESTATA PER POMPA A MEMBRANA†⠀ œHEAD FOR DIAPHRAGM PUMPâ €
La presente invenzione inerisce alle pompe a membrana ad alta pressione, ed in particolare ad una testata comprendente, oltre alla camera di pompaggio, anche i condotti di aspirazione e scarico. The present invention relates to high pressure diaphragm pumps, and in particular to a head comprising, in addition to the pumping chamber, also the intake and exhaust ducts.
Le pompe a membrana, che possono essere realizzate ad uno o elementi pompanti, comprendono per ogni elemento pompante un pistone scorrevole in modo alternativo all’interno di un cilindro di guida. Diaphragm pumps, which can be realized with one or pumping elements, include for each pumping element a piston sliding in an alternative way inside a guide cylinder.
Il cilindro di guida del pistone à ̈ separato dalla camera di pompaggio da una membrana che à ̈ fissata perifericamente tra la camera di pompaggio ed il cilindro, ed al centro à ̈ fissata al centro del pistone. The piston guide cylinder is separated from the pumping chamber by a membrane which is peripherally fixed between the pumping chamber and the cylinder, and in the center it is fixed to the center of the piston.
La camera di pompaggio à ̈ ricavata in una testata che comprende anche i condotti di aspirazione e di scarico. The pumping chamber is made in a head which also includes the intake and exhaust ducts.
La testata à ̈ assoggettata a forti sollecitazioni meccaniche ed à ̈ unita al corpo della pompa, contenente il cilindro di guida del pistone ed i mezzi di azionamento alternativo di quest’ultimo, mediante bulloni. The head is subjected to strong mechanical stresses and is joined to the pump body, containing the piston guide cylinder and the alternative actuation means of the latter, by means of bolts.
Le sollecitazioni meccaniche indotte sulla testata dalla pressione di pompaggio sono molto elevate, e richiedono che la testata possieda una rigidezza tale da evitare deformazioni compromettenti la tenuta idraulica tra la testata ed il corpo della pompa. The mechanical stresses induced on the head by the pumping pressure are very high, and require the head to have such a stiffness as to avoid deformations compromising the hydraulic seal between the head and the pump body.
Secondo la tecnica nota la testata à ̈ realizzata in materiale metallico, il che ne garantisce la necessaria rigidezza e la mancanza di deformazioni tra i bulloni di fissaggio della testata ed il corpo della pompa. According to the known art, the head is made of metallic material, which guarantees the necessary rigidity and the absence of deformations between the head fixing bolts and the pump body.
Tentativi di costruire, per ovvi motivi di economia, la testata in materiale sintetico hanno reso necessaria la adozione di un numero di bulloni di fissaggio tra testata e corpo della pompa superiore a quattro, generalmente sei. Attempts to build the cylinder head in synthetic material, for obvious reasons of economy, made it necessary to use more than four fixing bolts between the cylinder head and the pump body, generally six.
Se il fissaggio demandato a sei bulloni si à ̈ rivelato sufficiente ad evitare dannose deformazioni della testata, esso ha tuttavia dato origine ad ulteriori inconvenienti, poiché richiede di progettare anche il corpo della pompa con sei sedi per i bulloni, al posto delle classiche quattro sedi. While the six-bolt fastening proved to be sufficient to avoid damaging deformations of the cylinder head, it has nevertheless given rise to further drawbacks, since it also requires the design of the pump body with six seats for the bolts, instead of the classic four. locations.
Ciò quantomeno rende difficile adottare testate in materiale sintetico per pompe progettate per ricevere testate in materiale metallico, ed ha fortemente limitato l’impiego del materiale sintetico nella costruzione delle testate. This at least makes it difficult to adopt synthetic material heads for pumps designed to receive metal heads, and has severely limited the use of synthetic material in the construction of the heads.
Lo scopo della presente invenzione à ̈ di rendere disponibile una testata costruita in materiale sintetico, la quale presenti una rigidezza comparabile con quella delle testate in materiale metallico, e possa essere quindi fissata al corpo della pompa progettato per ricevere le testate metalliche fissate con solo quattro bulloni. The purpose of the present invention is to make available a head made of synthetic material, which has a stiffness comparable to that of the heads made of metallic material, and can therefore be fixed to the pump body designed to receive the metal heads fixed with only four bolts.
Questo scopo à ̈ conseguito dalla particolare configurazione della testata descritta nella rivendicazione indipendente. Le rivendicazioni dipendenti descrivono caratteristiche subordinate atte a migliorare le prestazioni del trovato. I pregi e le caratteristiche funzionali e costruttive del trovato saranno resi chiari dalla particolareggiata descrizione che segue che, con l’aiuto delle figure delle allegate tavole disegni, ne illustra una preferita forma di attuazione data a titolo di esempio non limitativo. This object is achieved by the particular configuration of the head described in the independent claim.

La Fig.5 mostra la sezione V-V di Fig.2. Fig.5 shows the V-V section of Fig.2.
La Fig.6 mostra la sezione VI-VI di Fig.1. Fig.6 shows the section VI-VI of Fig.1.
La Fig.7 mostra una vista prospettica del trovato. Fig.7 shows a perspective view of the invention.
Dalle figure si rileva il corpo monolitico 1 della testata ricavato in un materiale sintetico ad alta resistenza, dotato di quattro formelle 2 contenenti i fori per il fissaggio al corpo della pompa non mostrato. The figures show the monolithic body 1 of the head made of a high-strength synthetic material, equipped with four molds 2 containing the holes for fixing to the pump body, not shown.
Il corpo 1 presenta inferiormente una sede anulare piana 3 per l’appoggio sulla guarnizione che lo separa dal corpo della pompa, non mostrato (Fig.2). The body 1 has a flat annular seat 3 at the bottom for resting on the gasket that separates it from the pump body, not shown (Fig.2).
La base 3 comprende una scanalatura anulare 31 per ricevere il bordo della membrana. The base 3 comprises an annular groove 31 for receiving the edge of the membrane.
Al di sopra della base 3 e della scanalatura 31 Ã ̈ ricavata una camera emisferica 4 (Fig.5), che costituisce la camera di pompaggio. Above the base 3 and the groove 31 there is a hemispherical chamber 4 (Fig. 5), which constitutes the pumping chamber.
Al centro della camera 4 Ã ̈ presente una cupola 40, ad andamento diametrale, di diametro minore (Fig.5). In the center of chamber 4 there is a dome 40, with a diametrical trend, of smaller diameter (Fig. 5).
Da detta camera 4 e cupola 40 si derivano due condotti contrapposti 41 e 42, rispettivamente il condotto di aspirazione ed il condotto di scarico. From said chamber 4 and dome 40 two opposite ducts 41 and 42 are derived, respectively the intake duct and the exhaust duct.
Il corpo dei condotti 41 e 42 à ̈ unito senza soluzione di continuità con le formelle 2 dei fori di fissaggio, ed à ̈ attraversato da fori 43 (Fig.1), per il collegamento alla tuberia della pompa. The body of the ducts 41 and 42 is joined seamlessly with the molds 2 of the fixing holes, and is crossed by holes 43 (Fig.1), for connection to the pump tubing.
Alla sommità della testata, nell’intorno della camera 4 e della cupola 40, si estende una parete esterna 5 leggermente sagomata e sostanzialmente parallela alla sede 3 (Fig.3). Detta parete 5 à ̈ unita alla base piana 3 mediante quattro fazzoletti 51 posti in direzione diagonale tra le formelle 2 in corrispondenza delle formelle 2, ed à ̈ invece staccata dalla base 3 nelle zone poste tra le formelle 2. At the top of the head, around the chamber 4 and the dome 40, extends an external wall 5 slightly shaped and substantially parallel to the seat 3 (Fig.3). Said wall 5 is joined to the flat base 3 by means of four handkerchiefs 51 placed diagonally between the tiles 2 in correspondence with the tiles 2, and is instead detached from the base 3 in the areas between the tiles 2.
La parete 5 Ã ̈ unita alla base 3 dal corpo dei condotti di aspirazione e di scarico 41 e 42. Wall 5 is joined to base 3 by the body of the intake and exhaust ducts 41 and 42.
La parete 5, nella direzione ortogonale agli assi dei fori 41 e 42, Ã ̈ unita alla base 3 da una costolatura 52 per ogni lato. The wall 5, in the direction orthogonal to the axes of the holes 41 and 42, is joined to the base 3 by a rib 52 for each side.
La base 3 e la parete 5 formano una struttura sostanzialmente a sandwich, avente per base la sede 3 e per sommità la parete 5. The base 3 and the wall 5 form a substantially sandwich structure, having the seat 3 as its base and the wall 5 as its top.
La presenza tra la base e la sommità del corpo 1 delle costolature 52, del corpo dei condotti di aspirazione e di scarico 41 e 42, nonché dei fazzoletti 51 conferisce alla struttura una rigidezza tra i fori 2 comparabile a quella di un corpo metallico. The presence between the base and the top of the body 1 of the ribs 52, of the body of the intake and exhaust ducts 41 and 42, as well as of the gussets 51 gives the structure a rigidity between the holes 2 comparable to that of a metal body.
Si intende che varianti e perfezionamenti potranno essere apportati alla invenzione senza uscire dall’ambito delle seguenti rivendicazioni. It is understood that variations and improvements may be made to the invention without departing from the scope of the following claims.
