Scheme de conducte hidraulice pentru cazane pe pele\u021bi FOCUS<\/h1>\n

Invit\u0103m cititorii \u0219i cump\u0103r\u0103torii s\u0103 se familiarizeze cu schemele de conducte ale unui cazan pe pele\u021bi. Circuitele hidraulice au ca scop automatizarea procesului de \u00eenc\u0103lzire. Exemple de diagrame de conducte hidraulice pentru cazanele FOCUS v\u0103 vor ajuta s\u0103 instala\u021bi o camer\u0103 de cazane f\u0103r\u0103 proiectare preliminar\u0103, dac\u0103 parametrii sistemului difer\u0103 u\u0219or.<\/p>\n

Pentru a \u00eembun\u0103t\u0103\u021bi circula\u021bia apei \u00een circuitul gravita\u021bional al cazanului este necesar: s\u0103 se foloseasc\u0103 diametre nominale mari DN de \u021bevi \u0219i o supap\u0103 cu patru c\u0103i, s\u0103 se evite un num\u0103r mare de coturi \u0219i reduceri de diametru, s\u0103 se respecte alte reguli privind proiectarea a sistemelor gravita\u021bionale, de exemplu, men\u021binerea pic\u0103turilor etc. <\/strong><\/p><\/blockquote>\n

Dac\u0103 senzorul de retur este montat deasupra capului, acesta ar trebui s\u0103 fie izolat termic de mediul \u00eenconjur\u0103tor \u0219i s\u0103 \u00eembun\u0103t\u0103\u021beasc\u0103 contactul termic cu conducta folosind past\u0103 termoconductoare. Temperatura prestabilit\u0103 a cazanului trebuie setat\u0103 la un astfel de nivel \u00eenc\u00e2t s\u0103 poat\u0103 fi asigurat\u0103 puterea termic\u0103 pentru circuitul mixerului \u00een timp ce simultan se \u00eenc\u0103lze\u0219te apa care revine \u00een cazan.<\/strong><\/p>\n
