3 TENUTA MECCANICA La tenuta meccanica è quel dispositivo che installato su un albero rotante di una macchina trattiene un fluido (liquido o gas) all interno della stessa impedendo che esso venga disperso nell ambiente esterno. Esempi tipici di macchine dove vengono installate le tenute meccaniche sono: pompe centrifughe, compressori, agitatori, mixer ecc. ecc. Nel corso degli anni si sono sviluppate diverse tipologie di tenute meccaniche, suddivise in statiche o dinamiche, a contatto (assiale) o non-contatto. TS opera principalmente con le tenute a contatto assiale. La tenuta meccanica frontale, rispetto a quella radiale, si utilizza su diverse applicazioni ed in condizioni più critiche. COMPOSIZIONE DI UNA TENUTA MECCANICA La tenuta meccanica (Fig. 1) è composta da due anelli in posizione rotante e stazionario, chiamati facce di tenuta, i quali sono mantenuti in contatto assiale da due forze principali: una, quella meccanica, generata dalle molle/soffietto della tenuta e l altra, idraulica, generata dalla pressione del fluido da contenere. 1 Anello Rotante 2 Anello/Seggio Stazionario 3 Molla 4 O-Ring dinamico (assialmente) 5 O-Ring statico Nella maggioranza delle applicazioni, la forza meccanica è generata da una molla elicoidale (monomolla), in altri da una serie di piccole molle sempre elicoidali (multispring), o da una molla ad 3

4 onda, o un soffietto che può essere elastomerico, in materiale termoplastico (PTFE) o metallico. Il valore dela forza idraulica che mantiene in contatto le facce di tenuta è caratterizzata dal grado di bilanciamento idraulico, valore ottenuto dal rapporto dell area di chiusura, sulla quale agisce il fluido, e l area di apertura, dove agisce il meato di fluido tra le facce di tenuta. Esempio delle forze che determinano il bilanciamento idraulico in fig. 2 Le tenute meccaniche possono lavorare con il fluido di processo sia sull esterno che sull interno o con fluidi differenti su entrambi i lati, ovviamente si dovrà progettare in modo corretto la tenuta stessa in modo che possa operare sul lato dove avremo il fluido con la pressione maggiore. Le tenute meccaniche per servizi generici sono del tipo non bilanciate e operano con fluidi in pressione che agiscono sulla parte esterna, solitamente non resistono a pressioni superiori ai 20 bar e velocità periferiche massime di 20 m/sec. Oltre tali valori (pressione e velocità) dobbiamo utilizzare una tenuta meccanica bilanciata, ossia una tenuta meccanica che abbia un carico/forza limitato sulle facce di tenuta per 2 motivi principali: evitare l incremento di temperatura e rompere il meato d liquido lubrificante presente tra le facce stesse. L aumento di temperatura tra le facce porta alla distorsione dei piani di tenuta (generalmente piani lappati con planarità entro 0,9µm max) e di conseguenza ad una perdita del fluido.. Per realizzare una tenuta meccanica bilanciata dobbiamo considerare il carico/forza totale che agisce sull area DE-DM: [(DE2-DM2)x 3,14 :4]xP1 = Cf Kg E verificare che sia leggermente superiore al carico forza di apertura dove consideriamo una pressione pari a P1½, in quanto avremo la pressione la pressione P1 sul lato DE e avremo la pressione P2 (che consideriamo lato ambiente e quindi uguale a 0 ) sul lato DI : [(DE2-DI2)x3,14 :4]xP1 ½ = Of Kg Per semplificazione otterremo la formula che determina il rapporto di bilanciamento: Per P1 > P2 (DE2-DM2) : (DE2-DI2) = K Per P1 > P2 (DM2-DI2) : (DE2-DI2) = K Dove: DM = Diametro Medio DE = Diametro Esterno DI = Diametro Interno 4

5 K = Grado di bilanciamento (sempre compreso fra 0,6 e 0,8) Cf = Closing force Of = Opening force TIPI DI TENUTE E LIMITI OPERATIVI MATERIALI Le ns. tenute meccaniche sono realizzate utilizzando i seguenti materiali: Parti metalliche: - Acc. Inox - Acc. Legati - Acc. Spec. - Titanio Facce di tenuta e Anelli Seggi: - Grafite impregnata resina - Grafite impregnata metallo - Grafite FDA approved per uso alimentare e farmaceutico - Carburo di Silicio Reaction Bonded - Carburo di Silicio Sintered - Carburo di Tungsteno Co - Carburo di Tungsteno Ni - Ceramica (Al-Oxide) - Acc. con riporti antiusura Elastomeri: - NBR - EPDM - FKM - PFKM - PTFE Quanto sopra indicato sono le nozioni basilari per comprendere il funzionamento di una tenuta meccanica e a volte utili per capire le cause dei fallimenti, ovviamente ci sono molteplici aspetti che i ns. tecnici considerano ogni volta che effettuano una selezione idonea alle Vs. esigenze; ed è per questo motivo che Vi invitiamo a contattarci mandando una mail a tech@technicalsolutions.it nel caso abbiate richieste particolari. 5
