Malangizo ogwiritsira ntchito
Kugwiritsa ntchito
AV'TQ ndi njira yoyendetsera kutentha yomwe imayendetsedwa ndi kutuluka kuti igwiritsidwe ntchito ndi osinthanitsa kutentha kwa mbale pamadzi otentha omwe amawotcha pamakina otenthetsera m'chigawo. Valve imatseka pakukweza kutentha kwa sensor.
Dongosolo
AVTQ ingagwiritsidwe ntchito ndi mitundu yambiri ya osinthanitsa kutentha mbale (mkuyu 5). Wopanga kutentha ayenera kulumikizidwa kuti atsimikizire:
- kuti AV'TQ yavomerezedwa kuti igwiritsidwe ntchito ndi osinthanitsa osankhidwa
- kusankha koyenera kwazinthu polumikiza zosinthira kutentha,
- kugwirizana kolondola kwa mbale imodzi yowotcha kutentha; kusanjikiza kosanjikiza kumatha kuchitika, mwachitsanzo, kuchepetsedwa kutonthoza.
Machitidwe amagwira ntchito bwino pamene sensa imayikidwa mkati mwa chotenthetsera kutentha (onani mkuyu 1). Kuti mugwire bwino ntchito yosanyamula katundu, kutentha kwa madzi kuyenera kupewedwa chifukwa madzi otentha adzakwera ndipo motero amawonjezera madzi osanyamula katundu. Kuti muzitha kuyendetsa bwino maulumikizidwe amphamvu, masulani mtedza (1), sinthani gawo la diaphragm kukhala malo omwe mukufuna (2) ndikumangitsa mtedza (20 Nm) - onani mkuyu. 4.
Zindikirani kuti kuthamanga kwamadzi kuzungulira sensa kuyenera kukhala molingana ndi zofunikira za chubu chamkuwa.
Kuyika
Ikani chiwongolero cha kutentha mu mzere wobwerera kumbali yoyamba ya chotenthetsera kutentha (mbali yotentha ya chigawo). Madziwo ayenera kuyenda molunjika kumene muviwo walowera. Ikani valavu yowongolera ndi kutentha kwa kutentha pa kugwirizana kwa madzi ozizira, ndi kutuluka kwa madzi kumalo a muvi. Mitsempha ya machubu a capillary chubu isaloze pansi. Gwirizanitsani sensa mkati mwa chotenthetsera kutentha; kulunjika kwake kulibe kofunika (mkuyu 3).
Tikupangira kuti fyuluta yokhala ndi max. Kukula kwa mauna a 0.6 mm kuyikidwa patsogolo pa kuwongolera kutentha komanso patsogolo pa valve yowongolera. Onani gawo "Kulephera kwa ntchito".
Kukhazikitsa
Zofunikira zotsatirazi ziyenera kukwaniritsidwa kuti mupeze ntchito yopanda vuto:
- Q sekondale min.
- AVTQ DN 15 = 120 1/h
- AVTQ DN 20 = 200 Vh
- APVTQ mphindi
- AVTQ DN 15 = 0.5 bar
- AVTQ DN 20 = 0.2 bar
Asanakhazikike, dongosololi liyenera kuthamangitsidwa ndi kutulutsa mpweya, kumbali yoyamba ndi yachiwiri ya chotenthetsera kutentha. Machubu a capillary kuchokera ku valavu yoyendetsa kupita ku diaphragm ayeneranso kutulutsa mpweya ku (+) komanso (-) mbali. ZINDIKIRANI: Ma valve omwe amaikidwa mumayendedwe ayenera kutsegulidwa nthawi zonse ma valve asanakhazikitsidwe pobwerera. Kuwongolera kumagwira ntchito ndi kutentha kosasunthika kosasunthika (mafunde) komanso kutentha kosinthika.
Tsegulani chiwongolerocho mpaka kutuluka kwapang'onopang'ono komwe kumafunikira kupezeke ndikukhazikitsa kutentha kofunikira potembenuza chowongolera. Dziwani kuti dongosololi limafunikira nthawi yokhazikika (pafupifupi 20 s) pokhazikitsa komanso kuti kutentha kwapampopi kumakhala kocheperako kuposa kutentha kotuluka.
T max. mphindi. = pafupifupi 5 c pansi pa T primary flow
Type T kupha
- AVTQ 15 40 oc
- AVTQ 20 35 oc
Ntchito kulephera
Ngati valavu yowongolera ikulephera, kutentha kwamadzi otentha kudzakhala kofanana ndi kutentha kosalemetsa. Chifukwa cha kulephera kungakhale tinthu ting'onoting'ono (monga miyala) kuchokera kumadzi a utumiki. Chifukwa cha vutoli chiyenera kukonzedwa mwamsanga, choncho timalimbikitsa kuti fyuluta ikhale patsogolo pa valve yolamulira. Pakhoza kukhala zigawo zowonjezera pakati pa kutentha kwa unit ndi diaphragm. Dziwani kuti kuchuluka komweko kwa zida zowonjezera zimakwezedwanso, ngati sichoncho kutentha sikukhala 350C (400C) monga tanenera.
Mafunso Ofunsidwa Kawirikawiri
- Q: Kodi cholinga cha AVTQ ndi chiyani?
- A: AVTQ ndi kayendedwe ka kutentha koyendetsedwa ndi kutuluka komwe kumagwiritsidwa ntchito ndi osinthanitsa kutentha kwa mbale pamakina otentha a zigawo.
- Q: Ndiyike bwanji sensa kuti ikhale ndi zotsatira zabwino?
- A: Sensa iyenera kuyikidwa mkati mwa chotenthetsera kutentha monga momwe tawonetsera pa chithunzi 1 kuti igwire bwino ntchito.
- Q: Kodi ndi zotani zocheperako zoyenda komanso zokakamiza?
- A: Mayendedwe ocheperako ndi AVTQ DN 15 = 120 l/h ndi AVTQ DN 20 = 200 l/h. Zofunikira zokakamiza ndi AVTQ DN 15 = 0.5 bar ndi AVTQ DN 20 = 0.2 bar.
