I-Danfoss AVTQ 20 Flow Controlled Temperature Control
Isicelo
I-AVTQ isilawuli sezinga lokushisa esilawulwa ukugeleza ngokuyinhloko ukuze sisetshenziswe nezishintshisi zokushisa zamapuleti zamanzi ashisayo esevisi kumasistimu okushisa esifunda. I-valve ivala lapho izinga lokushisa lenzwa likhuphuka.
Uhlelo
I-AVTQ ingasetshenziswa nezinhlobo eziningi zokushintshanisa ukushisa kwepuleti (umkhiwane 5). Umkhiqizi wesishintshi sokushisa kufanele athintwe ukuze kuqinisekiswe:
- ukuthi i-AVTQ igunyaziwe ukuthi isetshenziswe ne-exchanger ekhethiwe
- ukukhethwa kwezinto ezifanele lapho uxhuma izishintshisi zokushisa,
- ukuxhumana okulungile kwesishintshi sokushisa se-pass plate eyodwa; ukusatshalaliswa kwezingqimba kungase kwenzeke, okungukuthi ukunethezeka okuncishisiwe.
Amasistimu asebenza kahle kakhulu lapho inzwa ifakwe khona kanye ngaphakathi kwesishintshi sokushisa (bona umkhiwane 1).
Ukuze uthole umsebenzi olungile ongalayishi, ukugeleza okushisayo kufanele kugwenywe njengoba amanzi ashisayo azokhuphuka futhi ngaleyo ndlela andise ukusetshenziswa okungalayishiwe. Ukuze uthole ukuma okuhle kokuxhunywa kwengcindezi khulula inadi (1), vula ingxenye ye-diaphragm ibe indawo oyifunayo (2) bese uqinisa inathi (20 Nm) - bheka i-fig. 4.
Qaphela ukuthi ijubane lamanzi elizungeze inzwa kufanele libe ngokwezidingo zeshubhu yethusi.
Ukufakwa
Faka isilawuli sezinga lokushisa emugqeni wokubuyisela ohlangothini oluyinhloko lwesishintshi sokushisa (uhlangothi lokushisa lwesifunda). Amanzi kufanele ageleze aye ngakulo umcibisholo. Faka i-valve yokulawula enokusetha kwezinga lokushisa emanzini abandayo okuqondisa kuyo i-wow. Izingono zokuxhuma kweshubhu le-capillary akufanele zibheke phansi. Faka inzwa ngaphakathi ku-excnanger ehlanzekile; ukuma kwawo akubalulekile (umfanekiso 3).
Sincoma ukuthi kube nesihlungi esinobuningi. Usayizi wemeshi ongu-0.6 mm ufakwe ngaphambi kokulawula izinga lokushisa nangaphambi kwevalvu yokulawula. Bheka isigaba “Ubude bomsebenzi.
Ukusetha
Izidingo ezincane ezilandelayo kufanele zihlangatshezwe ukuze kutholwe ukusebenza okungenazinkinga:
Ngaphambi kokusetha, isistimu kufanele igezwe futhi ikhiphe umoya, kokubili ohlangothini oluyinhloko kanye nohlangothi lwesibili lwesishintshi sokushisa. Amashubhu e-capillary asuka ku-valve yokushayela ukuya ku-diaphragm kufanele nawo aphume umoya ohlangothini (+) kanye nasohlangothini (-).
QAPHELA: Ama-valve afakwe ekugelezeni kufanele ahlale evuliwe ngaphambi kokuba ama-valve afakwe ekubuyiseleni. Isilawuli sisebenza ngezinga lokushisa elingaguquki elingalayishi (i-tide) kanye nezinga lokushisa elilungisekayo lokuthepha.
Vula isilawuli kuze kutholakale ukugeleza kokuthepha okudingekayo futhi usethe izinga lokushisa elidingekayo ngokuphendula isibambo sokulawula. Qaphela ukuthi isistimu idinga isikhathi sokuzinza (cishe amasekhondi angu-20) uma isetha nokuthi izinga lokushisa elithephayo lizohlala liphansi kunezinga lokushisa lokugeleza.
Ukuhluleka komsebenzi
Uma i-valve yokulawula iwa, izinga lokushisa lokungewona amanzi lizofana nezinga lokushisa elingalayishi. Imbangela yokwehluleka kungaba yizinhlayiyana (isb. Isizathu senkinga kufanele silungiswe ngokushesha ngangokunokwenzeka, ngakho-ke, sincoma ukuthi isihlungi sifakwe ngaphambi kwe-valve yokulawula. Kungase kube nezingxenye ezinwetshiwe phakathi kweyunithi yezinga lokushisa kanye ne-diaphragm. Qaphela ukuthi inani elifanayo lezingxenye ezinwetshiwe liyakhwezwa kabusha, uma kungenjalo izinga lokushisa lokungalayishi ngeke libe ngu-35°C (40°C) njengoba kushiwo.
