Ngazi kanjani ukuthi into yami yokushisa imbi
Kunezindlela eziningana zokunquma ukuthi ngabe ishubhu lokushisa lilimele:
Bheka isimo sokusebenza se-tube yokushisa: Uma ishubhu lokushisa lingakwazi ukushisa ngokujwayelekile, noma umphumela wokushisa awunakulihle njengakuqala, kungaba yinto engalungile nge-tube yokushisa {{0}
1. Sebenzisa i-multimeter ukukala:
Ukulinganisa ukumelana: Sebenzisa uhla oluncane lokumelana ne-multimeter ukukala inani lokumelana le-terminal tube yeshubhu elifudumele kufanele kube ngaphansi kwamakhulu ama-ohms
2. ukukala ukusebenza kwe-insulation:
Sebenzisa uhla lokumelana oluphezulu lwe-multimeter ukukala inani lokumelana phakathi kokuphela kwe-terminal kanye nenani elijwayelekile le-kilo-ohms, kusho ukuthi ukumelana kuncishisiwe kuphela uma kukhona ubungozi bokuvuza .
3. hlola ukufundwa kwe-ammeter:
Uma ishubhu lokushisa lilimele, i-thermostat izokhombisa ukuthi inikwa amandla okushisa, kepha isikhombi se-ammeter ngeke sihambise noma ukufundwa kungu-zero, okubonisa ukuthi ishubhu lokushisa alikwazi ukunikezwa amandla .
4. gcina umphumela wokushisa:
Uma izinga lokushisa le-tube yokushisa alikwazi ukufinyelela inani elisethiwe, noma ukufudumeza akulingani, ingaphezulu libuthuntu noma uketshezi lumpofu, ishubhu lokushisa lingalinyazwa .
Amaphuzu alandelayo kufanele aqashelwe lapho uvivinya ikhwalithi yeshubhu lokushisa:
Amandla okupholile futhi apholile: ngaphambi kokulinganisa, qiniseka ukuthi ishubhu lokushisa liphethwe amandla bese lipholile liye ngezinga elithile . Lokhu kungakugwema ubungozi bokushaqeka kwamaphutha kagesi ne- .
1. Sebenzisa amathuluzi afanele:
Sebenzisa amathuluzi wokuhlola ochwepheshe njengama-thermocouple thermometers, ama-thermometers we-infrareter, multimeters noma ukumelana nokulinganisa izinsimbi {{0
2. Ukusabalalisa nokulinganisa:
Ngaphambi kokusebenzisa i-thermometer, ake aqale futhi amaminithi 5-10 ukufinyelela okushisa okukhona ngasikhathi sinye, kunconywa ukuvivinya ishubhu elijwayelekile lokushisa layo kanye nenani lamanje ngaphambi kokuxazulula inkinga .
3. ukuhlolwa kokubukeka:
Ukubonakala ukubonakala kokuvela kweshubhu lokushisa ukuze uhlole ukulimala okusobala okufana nemifantu, ikhefu noma ukugqwala . Lokhu kungaba yizimpawu zokulimala kweshubhu lokushisa .
4. isilinganiso sokumelana:
Sebenzisa ithuluzi lokulinganisa le-multimeter noma ukumelana nokuvimba ama-clamps test emaphethelweni womabili ama-tube yokushisa, Qopha inani lokumelana bese uliqhathanisa nenani elilinganiselwe, kungakhombisa ukuthi ishubhu lokufudumala linephutha .
5. Ukulinganiswa kokufakwa:
Sebenzisa ithuluzi lokulinganisa lokulwa nokungena kokuhlola ukubheka ukusebenza kwe-invutha yeshubhu lokushisa . Xhuma umphetho owodwa ku-tube yokushisa noma ukuphela kwe-{{1}
6. Ukulinganisa kokushisa:
Sebenzisa i-thermometer noma i-thermometer ye-infrared ukukala izinga lokushisa le-tube yokushisa bese uyiqhathanisa nebanga lokushisa elijwayelekile lokushisa . Uma izinga lokushisa lingejwayelekile, kungakhombisa ukuthi ishubhu lokushisa linephutha
7. Vikela imishini yokuhlola:
Lapho ulinganisa okwamanje, naka ukuvikela isiqephu sokuhlola ukuze ugweme umjikelezo omfushane; Lapho ulinganisa lokushisa, naka ukuvikela i-thermometer ukugwema ukulimala .
