Imiyalo yokusetshenziswa
Isicelo
I-AV'TQ iyisilawuli sokushisa esilawulwa ukugeleza okugeleza 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-AV'TQ ivunyelwe ukusetshenziswa ne-exchanger ekhethiwe
- ukukhethwa kwezinto ezifanele lapho uxhuma izishintshisi zokushisa,
- ukuxhumeka okulungile kwezishintshi zokushisa ze-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 kusebenze kahle ukungalayishi, ukugeleza okushisayo kufanele kugwenywe njengoba amanzi ashisayo ezonyuka futhi ngaleyo ndlela andise ukusetshenziswa okungalayishiwe. Ukuze uthole ukuma okuhle kokuxhuma 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 lihambisane nezidingo zethubhu 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 oxhunyweni lwamanzi abandayo, nokugeleza kwamanzi ngakumcibisholo. Izingono zokuxhuma kweshubhu le-capillary akufanele zibheke phansi. Faka inzwa ngaphakathi kwesishintshi sokushisa; ukuma kwawo akubalulekile (umkhiwane 3).
Sincoma ukuthi kube nesihlungi esinobuningi. Usayizi wemeshi ongu-0.6 mm ufakwe ngaphambi kokulawula izinga lokushisa nangaphambi kwevalvu yokulawula. Bona isigaba “Ukwehluleka komsebenzi”.
Ukusetha
Izidingo ezincane ezilandelayo kufanele zihlangatshezwe ukuze kutholwe ukusebenza okungenazinkinga:
- Q yesibili min.
- I-AVTQ DN 15 = 120 1/h
- I-AVTQ DN 20 = 200 Vh
- I-APVTQ min
- I-AVTQ DN 15 = ibha engu-0.5
- I-AVTQ DN 20 = ibha engu-0.2
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 lokuthepha lizohlala lingaphansi kwezinga lokushisa lokugeleza.

Ukuhluleka komsebenzi
Uma i-valve yokulawula ihluleka, izinga lokushisa lokudonsa amanzi ashisayo 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 ziphinde zikhwezwe, uma kungenjalo izinga lokushisa lokungalayishi ngeke libe ngu-350C (400C) njengoba kushiwo.
imibuzo ejwayelekile ukubuzwa
- Q: Iyini inhloso ye-AVTQ?
- A: I-AVTQ isilawuli sokushisa esilawulwa ukugeleza esisetshenziswa ngokuyinhloko nezishintshisi zokushisa zamapuleti kumasistimu okushisa esifunda.
- Q: Kufanele ngifake kanjani inzwa ukuze uthole imiphumela ehamba phambili?
- A: Inzwa kufanele ifakwe ngaphakathi kwesishintshi sokushisa njengoba kukhonjisiwe kumfanekiso 1 ukuze usebenze kahle.
- Q: Yiziphi izilinganiso zokugeleza ezincane kanye nezidingo zengcindezi?
- A: Amazinga okugeleza amancane yi-AVTQ DN 15 = 120 l/h kanye ne-AVTQ DN 20 = 200 l/h. Izidingo zokucindezela yi-AVTQ DN 15 = ibha engu-0.5 ne-AVTQ DN 20 = ibha engu-0.2.
