Kusankha valavu ya mpira wamagetsi a Hvac

Kusankha valavu ya mpira wamagetsi ndikofunikira kuti mutseke dongosolo la HVAC, kudalirika, komanso kuwongolera molondola. Nawa zinthu zazikulu zofunika kuziganizira:

1. Kukula ndi kuthamanga

Fananizani kukula kwa valavu ya HVAC ili (mwachitsanzo, ½ "mpaka 4") kupewa zoletsa kapena kuponderezedwa kwamphamvu. Werengani kuwerengetsa kakulidwe kameneka (CV) potengera dongosolo la mitengo yoyenda ndi kupanikizika - ma vallvestives - osokoneza bongo amatha kuyambitsa kusagwirizana, pomwe owonjezera amatha kuwongolera, ngakhale oyang'anira kungayambitse kuwongolera koyenera.

2. Kugwirizana kwa zinthu zakuthupi

Matupi a valavu komanso zinthu zamkati ziyenera kukana kuwonongedwa kwa magetsi a Hvac (madzi, mabilidwe a glycol, kapena firiji). Makina opangidwa ndi madzi, mkuwa kapena chitsulo chimakhala ndi mtengo wokwera mtengo komanso wolimba. Kwa ozizira, kusankha chitsulo chosapanga dzimbiri . Zisindikizo ziyenera kugwiritsa ntchito EPDM kapena Viton kuti awonetsetse zolimba komanso zofanizira ndi madzi ampulogalamu.

3. Mtundu wa Acruator ndi Control

Sankhani pakati pa opanga / Off Assotor yosavuta / yotseka (mwachitsanzo, malo osungirako malo) ndikusintha oyeserera molondola (mwachitsanzo, malamulo otentha). Mavavu osintha, okhala ndi ma 0-10v kapena 4-20m Onetsetsani kuti kuwongolera kwa ochita chimbudzi kumafanana ndi kukula kwa valavu kuti mupewe kupanduka.

4. Kukakamizidwa ndi kuchuluka kwake

Chongani zolimbitsa thupi kwambiri Njira zotentha (mwachitsanzo, kuwombera kwa magetsi) kungafune mavuvu okhala ndi zisindikizo zosagwirizana ndi matupi.

5. Kudalirika ndi kukhazikitsa

Kuyika mavesi omwe ali ndi ochita zamagetsi okhazikika (iP65 / iP67 Vesings kwa Shereuring) kuthana ndi HVAC. Yang'anani mawonekedwe ngati buku la anthu ambiri pakugwira ntchito mwadzidzidzi komanso kuphatikizidwa kosavuta (kulumikizidwa kapena kopindika) kuti muchepetse kukhazikitsa ndi kukonza.

Poganizira kukula, zida, mtundu wowongolera, komanso ma race a ntchito, mutha kusankha valavu ya mpira wamagetsi omwe amathandizira kukonza kwa HVAC ndikuchepetsa ndalama zothandizira kukonza.
