Thaj chaw thau installation kev ceev faj
Kub tes thermocouple installation kev ceev faj?
Thermocouple thermocouple tsuas yog siv thermal tiv thaiv lub raj, thiab cov tub ntxhais khib nyiab tuaj yeem tawm ntawm txoj kev, tus neeg siv tau tshav kub ntu ntawm vuam los yog cov ntsia hlau tsau rau ntawm lub ntsiab ntaus ntawv, thiab tom qab ntawd ces tus thermocouple yuav tsum tau ua cov hauj lwm.
Nws qhov kom zoo dua yog los txhim kho kev ua haujlwm thiab kev pab cuam lub neej ntawm kev tiv thaiv lub raj, thiab los pab kho lossis hloov thermocouple, tus qauv tam sim no siv dav. Kub tiv thaiv tube nrog ib tug tshwj xeeb txheej txheem ntawm kev sib sib zog nqus qhov muag ua technology, kawg ntawm lub phab ntsa tuab tuab thiab tsis muaj vuam, yog, tsis muaj cov khoom vim vuam kev loj hlob ntawm cov khoom, yog li cov cua kub poob siab muaj ib tug high mechanical lub dag lub zog thiab ua rau Corrosion. Thermocouple thermocouple raws li kev siv ntawm kev ua haujlwm siab, qhov kub thiab ntsuas tus nqi sib txawv, nrog ntau cov qauv sib txuas thiab kev txhim kho, tus neeg siv tau xaiv raws li kev siv txoj kev ywj pheej. Nyob rau tib lub sijhawm, cov khoom muag ntawm lub transmitter, tsis tas yuav txuag tau nyiaj hlau, thiab qhov kub transmitter tso zis 4 ~ 20mA txheem teeb liab, muaj peev xwm ua kom muaj zog tiv thaiv ua kom muaj, thiaj muaj kev ua tau zoo, hauv kev lag luam muaj ntau hom ntawv . Tab sis lub sij hawm installation muaj qee cov ntsiab lus ntxiv ntawm qhov chaw, yog me ntsis mloog, ces lub neej ntawm lub thermocouple thiab kev ntsuas yog zoo heev. Kev siv lub thermocouple thiab thermal ua haujlwm yuav tsum xyuam xim rau qhov ntsuas ntawm kev ntsuas kub, kev nyab xeeb thiab kev ntsuas yuav ua tau yooj yim rau kev khiav lag luam, thiab tsis cuam tshuam cov khoom siv thiab cov haujlwm ua haujlwm kom tau raws li cov kev cai saum toj no, kev xaiv ntawm thermocouple thiab thermal tsis kam ntawm qhov chaw nruab thiab Muab tso tob rau hauv qab no:
1, kom thermocouple thiab thermal tsis kam ntawm kev ntsuas thiab qhov ntsuas nruab nrab ntawm kev sib pauv cua kub puv hnub, yuav tsum yog ib qho tsim nyog xaiv qhov ntsuas qhov chaw, sim kom tsis txhob muaj lub valve, luj tshib thiab cov yeeb nkab thiab cov khoom siv ze ntawm kaum ntawm lub installation ntawm thermocouple lossis Thermal ua haujlwm.
2, nrog rau kev tiv thaiv kub nrog cua sov thiab cua sov, kom txo qhov kev ntsuas kev ntsuas, thermocouple thiab thermal ua haujlwm yuav tsum muaj txaus qhov tob:
(1) Rau cov thermocouples uas ntsuas qhov kub ntawm qhov chaw ntawm cov yeeb nkab, nws yog feem ntau yuav tsum tau muab qhov kawg ntsuas mus rau hauv nruab nrab ntawm cov yeeb nkab (ntsug los yog tilted). Yog tias txoj kab uas hla dej ntawm cov dej mus ntsuas yog 200 hli, thermocouple lossis thermal tsis zoo Qhov tob yuav tsum tau xaiv 100 hli;
(2) kub kub ntawm cov thermocouples rau kev kub thiab kev kub siab thiab kev ntsuas kub kub ntsuas (xws li lub zog npuas loj), kom txo tau lub tsho tiv thaiv ntawm kev ua haujlwm ntawm cov kua thiab tiv thaiv kev tiv thaiv lub hauv dej hauv qab qhov kev txiav txim ntawm pob txha, los yog kev siv thermocouple thermocouple. Lub teeb plug thermocouple tiv thaiv casing, lub tso ntawm lub ntsiab chav yeeb nkab qhov tob yuav tsum tsis pub tsawg tshaj 75 hli; thermocouple thermocouple txheem txheem qhov tob ntawm 100 hli;
(3) Yog tias koj xav tau los ntsuas qhov kub ntawm cov roj flue, Txawm hais tias lub voj voog ntawm 4m, thermocouple lossis thermal ua haujlwm tau muab tso rau hauv qhov tob ntawm 1m.
(4) Thaum ntsuas kub tho qhov ntsuas pib qhov tob ntawm qhov ntau tshaj 1m, yuav tsum muab nruab rau kom deb li deb tau, los yog qhov kev pabcuam thiab kev tiv thaiv kev tiv thaiv.
