Danfoss AVTQ 20 Flow Controlled Temperature Control
Application
AVTQ 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 AVTQ inotenderwa kuti ishandiswe neinochinjanisa yakasarudzwa
- iyo chaiyo sarudzo yezvinhu kana uchibatanidza kupisa kunopisa,
- kuwirirana kwakarurama kweimwe pass plate heat exchanger; kugoverwa kwe layer kunogona kuitika, kureva kuderedzwa kunyaradza.
Zvirongwa zvinoshanda zvakanyanya kana sensor yakaiswa mukati chaimo mukati mekupisa (ona fig. 1).
Nekuita kwakaringana hapana-mutoro basa, kuyerera kwekupisa kunofanirwa kudziviswa sezvo mvura inopisa ichikwira uye nekudaro kuwedzera iyo isina-mutoro kushandiswa. Kuti utarise zvakanangana zvekumanikidza kubatana sunungura nati (1), shandura iyo diaphragm chikamu mune inodiwa chinzvimbo (2) uye simbisa nati (20 Nm) - ona fig. 4.
Ziva kuti kumhanya kwemvura kwakatenderedza sensor kunofanirwa kuve nezvinodiwa zvehubhu yemhangura.
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 nzira yemvura yewow. Minyatso yecapillary tube connection haifanirwe kunongedza pasi. Isa iyo sensor mukati mune yakanaka excnanger; kutungamira 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 “Function tallure.
Setting
Zvinotevera zvishoma zvinodiwa zvinofanirwa kusangana kuti uwane kushanda kusina dambudziko:
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 kudzikamisa nguva (inenge 20 s) pakuseta uye kuti tembiricha Tembiricha inogara yakadzikira pane yekuyerera tembiricha.
Basa kutadza
Kana iyo valve yekudzora ikadonha, tembiricha isiri-yemvura-yekupopa ichava yakafanana neyeye-isina-mutoro tembiricha. Chikonzero chekukundikana chinogona kunge chiri zvidimbu (seg gravel) kubva mumvura yebasa. Chikonzero chechinetso chinofanira kugadziriswa nokukurumidza sezvinobvira, isu, naizvozvo, tinokurudzira kuti firiji iiswe pamberi pevhavha yekudzora. Panogona kunge paine zvikamu zvekuwedzera pakati petembiricha unit uye diaphragm. Ziva kuti huwandu hwakafanana hwezvikamu zvekuwedzera hunokwidziridzwa, kana zvisiri-yekuremerwa tembiricha haizove 35°C (40°C) sezvakataurwa.
