Umahluko phakathi kokwandiswa kwetyhubhu eshwabeneyo kunye nokwandiswa kwetyhubhu eshwabeneyo

Q: Intoni'Ngaba umahluko phakathi kokwandiswa kwetyhubhu eshwabeneyo kunye nokwandiswa kwetyhubhu eshwabeneyo?

A: 

Umahluko phakathi kweshwabana ukwandiswa ityhubhu kunyeengashwabenanga iinkqubo zokwandisa ityhubhu kutshintshiselwano lokushisa lubalulekile ngokwemigaqo kunye nezicelo.

Scutheka Ukwandiswa ityhubhu

Ishwabana inkqubo yokwandisa ityhubhu yindlela eqhelekileyo yokuvelisa ngoomatshini.Ngethuba lokwandiswa kwetyhubhu, ububanzi betyhubhu yobhedu buyanda ngenxa yobukhulu bebhola yokwandisa xa kuthelekiswa nobubanzi bangaphakathi bombhobho, okubangela ukudibanisa okungqongqo kunye neempumlo kunye nokuphucula ukuhanjiswa kobushushu bokutshintshana kobushushu.Nangona kunjalo, olu hlobo lokwandiswa kwetyhubhu lubangela ukwanda kwendawo enqamlezileyo yombhobho wethusi, okukhokelela ekunciphiseni ubude bombhobho, owaziwa ngokuba yi-copper shrinkage rate.Ngokomzekelo, kwishishini le-air conditioning, isantya sokuncipha kweetyhubhu zethusi ezifakwe ngaphakathi ngaphakathi ngokuqhelekileyo zi-3% -4%.

Sengenamashwa Ukwandiswa ityhubhu

The engashwabenanga inkqubo yokwandiswa kwetyhubhu yindlela yokwandisa iityhubhu enyanzelekileyo.Ihlawulela ukwanda kobubanzi bangaphakathi bobhedu ityhubhu ngokunyusa ubuninzi bodonga, ukuqinisekisa ukuba akukho kuncipha kubude betyhubhu yobhedu emva kokwandiswa kwetyhubhu.Le nkqubo idinga ukusetyenziswa kwesixhobo esikhethekileyo kumatshini wokwandisa ityhubhu ukuze ubambe iziphelo zetyhubhu kunyeI-hairpin-i-tube bottoms yamacandelo okutshintsha ubushushu ngaphambi kokwandiswa kwetyhubhu.Emva kokoengashwabenanga ukwandiswa ityhubhu, utshintsho lwenzeka kwi-diameter yangaphakathi kunye neeparitha zemicu yetyhubhu yethusi, ifuna ukuqinisekiswa kokusebenza kotshintshiselwano lobushushu, uxinzelelo lwenkqubo, kunye nokusebenza kwexesha elide lokutshintsha ubushushu.Ukongeza, ezinye zoyilo zeengashwabenanga Ukwandiswa ityhubhu kubandakanya iimbambo zangaphakathi ezisebenzisa amandla okuqina kumzimba wetyhubhu ngexesha lokwandiswa kwenkqubo, ukuthintela ukuncipha kwetyhubhu kunye nokuqinisekisa ukwandiswa kwetyhubhu efanayo ekuphuculeni ubushushu bokuqhuba.

Isishwankathelo, umahluko ophambili phakathishwabana kwayeengashwabenanga iinkqubo zokwandiswa ityhubhu zilele ukuba ityhubhu yobhedu iyancipha emva kokwandiswa kunye nendlela ukuyila inkqubo kunokwandisa ngayo ukusebenza komtshintshi wokushisa.Ukhetho oluthile lwenkqubo luxhomekeke kwiimfuno ezithile zesicelo kunye neemeko zenkqubo.
