1. Test caract\u00e9ristique du d\u00e9bit de la vanne<\/h2>\n\n\n\n

Installez la vanne de test dans la position correspondante du pipeline en fonction de sa taille, d\u00e9marrez le convertisseur de fr\u00e9quence pour augmenter sa fr\u00e9quence selon le taux sp\u00e9cifi\u00e9, la vitesse de la pompe augmente, la diff\u00e9rence de pression des deux c\u00f4t\u00e9s de la vanne change en cons\u00e9quence et obtenez la valeur de d\u00e9bit correspondante en m\u00eame temps. Lorsque la diff\u00e9rence de pression entre les deux c\u00f4t\u00e9s de la vanne atteint sa diff\u00e9rence de pression maximale ou que la fr\u00e9quence de fonctionnement atteint 50 Hz, le convertisseur de fr\u00e9quence ralentit et s'arr\u00eate automatiquement. Les donn\u00e9es du capteur de d\u00e9bit et du capteur de pression diff\u00e9rentielle ont \u00e9t\u00e9 enregistr\u00e9es et la courbe caract\u00e9ristique du d\u00e9bit de pression diff\u00e9rentielle a \u00e9t\u00e9 trac\u00e9e pour compl\u00e9ter l'exp\u00e9rience. FIGUE. 1 montre les r\u00e9sultats des tests de la courbe caract\u00e9ristique de d\u00e9bit de la vanne d'\u00e9quilibrage de d\u00e9bit.<\/p>\n\n\n\n

2\u3001Test de caract\u00e9ristique d'ouverture de vanne<\/h2>\n\n\n\n

Installez le r\u00e9gulateur avec actionneur sur la canalisation, ajustez l'ouverture de la vanne pour ajuster le d\u00e9bit et contr\u00f4lez la diff\u00e9rence de pression entre les deux extr\u00e9mit\u00e9s de la vanne \u00e0 100 kPa pour obtenir la courbe caract\u00e9ristique de d\u00e9bit ouvert. Voir la figure 2.<\/p>\n\n\n\n

3. Coefficient de d\u00e9bit de vanne, test du coefficient de r\u00e9sistance de vanne<\/h2>\n\n\n\n

La diff\u00e9rence de pression entre les deux extr\u00e9mit\u00e9s de la vanne d'eau est contr\u00f4l\u00e9e \u00e0 100 kPa et le d\u00e9bit de la vanne est mesur\u00e9 \u00e0 ce moment-l\u00e0. Le coefficient de d\u00e9bit peut \u00eatre obtenu en utilisant la formule (1) et le coefficient de r\u00e9sistance peut \u00eatre calcul\u00e9 par la formule (2), o\u00f9 V est le d\u00e9bit de la canalisation de vanne, calcul\u00e9 par la formule (3), et D est le diam\u00e8tre nominal. de la vanne. Une fois la proc\u00e9dure ci-dessus entr\u00e9e dans l'option de test, le rapport est automatiquement g\u00e9n\u00e9r\u00e9 par l'ordinateur.<\/p>\n\n\n\n

4. Test de r\u00e9gulation de pression du r\u00e9ducteur de pression et de la vanne diff\u00e9rentielle de pression<\/h2>\n\n\n\n

Le banc d'essai peut \u00eatre utilis\u00e9 pour tester la pression de sortie et la courbe de d\u00e9bit et de pression d'entr\u00e9e du d\u00e9tendeur<\/a>;La diff\u00e9rence de pression entre les deux extr\u00e9mit\u00e9s de la vanne de r\u00e9gulation de pression diff\u00e9rentielle et la courbe de variation du d\u00e9bit et de la pression d'entr\u00e9e peuvent \u00eatre mesur\u00e9es \u00e0 l'aide du tableau exp\u00e9rimental.<\/p>","protected":false},"excerpt":{"rendered":"
