Mirayiridzo yekushandisa
Application
AV'TQ inoyerera-inodzorwa tembiricha yekudzora inonyanya kushandiswa neplate heat exchangers yemvura inopisa sevhisi mumatunhu ekudziya masisitimu. Ivhavha inovhara pakukwira kwekushisa kwe sensor.
System
AVTQ inogona kushandiswa nemhando dzakawanda dzeplate heat exchangers (fig. 5). Mugadziri wekupisa kupisa anofanirwa kubatwa kuti ave nechokwadi:
- kuti AV'TQ inotenderwa kuti ishandiswe neinochinjanisa yakasarudzwa
- iyo chaiyo sarudzo yezvinhu kana uchibatanidza kupisa kunopisa,
- kuwirirana kwakarurama kweimwe pass plate heat exchangers; kugoverwa kwe layer kunogona kuitika, kureva kuderedzwa kunyaradza.
Zvirongwa zvinoshanda zvakanyanya kana sensor yakaiswa mukati chaimo mukati mekupisa (ona fig. 1). Kuti iite basa rechokwadi rekusatakura, kuyerera kwemafuta kunofanirwa kudzivirirwa sezvo mvura inopisa ichikwira uye nekudaro inowedzera kushandiswa-kusatakura. Kuti utarise zvakanangana zvekumanikidza kubatana sunungura nati (1), shandura chikamu chediaphragm kuita chinzvimbo chaunoda (2) uye simbisa nati (20 Nm) - ona fig. 4.
Cherechedza kuti kumhanya kwemvura kutenderedza sensor kunofanirwa kuenderana nezvinodiwa zvemhangura chubhu.
Installation
Isa tembiricha yekudzora mumutsara wekudzoka padivi rekutanga remoto wekudziya (district heating side). Mvura inofanira kuyerera yakananga kune museve. Isa vharafu yekudzora ine tembiricha yekumisikidza pane inotonhora yekubatanidza mvura, nekuyerera kwemvura kwakananga kumuseve. Minyatso yecapillary tube connection haifanirwe kunongedza pasi. Fita sensor mukati mekupisa kupisa; kutaridzika kwayo hakuna kukosha (fig. 3).
Tinokurudzira kuti sefa ine max. mesh saizi ye 0.6 mm inoiswa zvese pamberi pekutonga tembiricha uye pamberi pevharuvhu yekudzora. Ona chikamu "Kutadza kushanda".
Setting
Zvinotevera zvidiki zvinodiwa zvinofanirwa kuzadzikiswa kuti uwane mashandiro asina dambudziko:
- Q yechipiri min.
- AVTQ DN 15 = 120 1/h
- AVTQ DN 20 = 200 Vh
- APVTQ min
- AVTQ DN 15 = 0.5 bar
- AVTQ DN 20 = 0.2 bar
Usati wagadzika, iyo sisitimu inofanirwa kuve yakanyungudutswa uye kufefeterwa, zvese padivi rekutanga uye chikamu chechipiri cheanopisa. Machubhu ecapillary kubva kuvharuvhu yekutyaira kuenda kudiaphragm anofanirawo kuburitswa pa (+) pamwe ne (-) divi. CHERECHEDZA: Mavharuvhu akaiswa mukuyerera anofanira kugara akavhurwa mavharuvhu asati aiswa mukudzoka. Iyo inodzora inoshanda neyakagadziriswa isina-mutoro tembiricha (tide) uye inogadziriswa tembiricha yekubata.
Vhura iyo yekudzora kusvika iyo inodiwa yekuyerera kuyerera yawanikwa uye isa inodiwa yekutapa tembiricha nekushandura mubato wekutonga. Ziva kuti sisitimu inoda nguva yekudzikamisa (inenge 20 s) pakuseta uye kuti tembiricha yekubata inogara yakadzikira pane yekuyerera tembiricha.

Basa kutadza
Kana iyo vharafu yekudzora ikatadza, tembiricha yekupopa yemvura inopisa ichava yakafanana neyekushaikwa-mutoro tembiricha. Chikonzero chekukundikana chinogona kunge chiri zvidimbu (seg gravel) kubva mumvura yebasa. Chikonzero chechinetso chinofanira kugadziriswa nokukurumidza sezvinobvira, naizvozvo tinokurudzira kuti firiji iiswe pamberi pevhavha yekudzora. Panogona kunge paine zvikamu zvekuwedzera pakati petembiricha unit uye diaphragm. Ziva kuti huwandu hwakafanana hwezvikamu zvekuwedzera zvinokwidziridzwa, kana zvisiri-mutoro tembiricha haizove 350C (400C) sezvataurwa.
Mibvunzo Inowanzo bvunzwa
- Mubvunzo: Chii chinangwa cheAVTQ?
- A: AVTQ inoyerera-inodzorwa tembiricha yekudzora inonyanya kushandiswa neplate heat exchangers mumatunhu ekudziya masisitimu.
- Mubvunzo: Ndinofanira kuisa sei sensor kuti ndiwane mhedzisiro yakanaka?
- A: Sensor inofanira kuiswa mukati mekupisa kupisa sezvinoratidzwa mumufananidzo 1 kuitira kushanda kwakakwana.
- Q: Ndeapi mashoma ekuyerera kwemazinga uye kumanikidzwa zvinodiwa?
- A: Izvo zvishoma zvekuyerera kwemazinga ndeye AVTQ DN 15 = 120 l/h uye AVTQ DN 20 = 200 l/h. Zvinodiwa zvekumanikidzwa ndezveAVTQ DN 15 = 0.5 bar uye AVTQ DN 20 = 0.2 bar.
