Yiziphi izinhlobo zamapayipi ensimbi angenamthungo?
Okokuqala, amapayipi ensimbi angenamthungo anesiphambano esingenalutho, futhi amaningi awo asetshenziswa njengamapayipi okuthutha uketshezi, njengowoyela, igesi, igesi eliwuketshezi, amanzi, nezinye izinto ezingavuthiwe eziqinile. Uma kuqhathaniswa namapuleti ensimbi engagqwali ayisisekelo aqinile njengensimbi eyindilinga, amapayipi ensimbi angenamthungo anesisindo esilula uma kuqhathaniswa namandla okugoba, amandla okugoba, namandla acindezelayo kufana, okuwenza abe insimbi ethuthukiswe ngokwezomnotho. Ingaphezulu lamapayipi angenamthungo adiphu adiphu ashisayo afakwe uthayela wediphu eshisayo kanye nongqimba olwengeziwe lokumelana nokugqwala kanye nokwelashwa kwe-zinc okuvikela ukugqwala.
Okwesibili, izinsiza ezibalulekile zifaka i-10 #, 20 #, 35 #, 45 #, kanye ne-16Mn. Phakathi kwazo, i-20 # isetshenziswa kakhulu, kanti i-16Mn ibuye ibizwe ngokuthi i-Q345B ngabanye abantu.
Okwesithathu, ukusetshenziswa okuyinhloko kwamapayipi ensimbi angenamthungo ngokuvamile kufaka phakathi izigaba ezilandelayo:
1. Izihloko eziyinhloko zezokwakha zihlanganisa: ukuthutha ngamapayipi angaphansi komhlaba, ukudonsa amanzi angaphezulu lapho kwakhiwa izindlu, nokuthutha amanzi eziko lokushisisa.
2. Ukukhiqizwa komshini wokucutshungulwa, ama-roller bearings, ukukhiqiza nokukhiqiza imishini yemishini, njll.
3. Iziqu zikagesi: ukudluliswa kwegesi yemvelo, amapayipi amanzi kanye nogesi ophehla ugesi.
4. Amapayipi angaguquki, njll. ezitshalweni zamandla omoya.
Okwesine, ngokusetshenziswa okuyinhloko okuhlukene, amapayipi angahlukaniswa ngezigaba ezilandelayo:
1. Amapayipi omanyolo anomfutho ophezulu we-GB6479-2000 angasetshenziswa ezitshalweni zamakhemikhali namapayipi anamazinga okushisa asukela ku--40 kuya ku-400 ℃ nezingcindezi ezisukela ku-10-32Mpa.
2. I-GB/T8163-2008 iyipayipi lensimbi elivamile elingenamthungo elifanele ukudlulisa uketshezi.
3. Amapayipi esakhiwo esijwayelekile i-GB/T8162-2008 kanye ne-GB/T8163 afaneleka ukwakhiwa okujwayelekile, amafreyimu okusekela iphrojekthi yobunjiniyela, ukucubungula ngomshini nokukhiqiza, njll.
4. Ipayipi likawoyela elingangeni manzi le-ISO11960 lisetshenziswa njengomthombo wokukha uwoyela noma igesi emithonjeni kawoyela negesi.
Okwesine, ngokusetshenziswa okuyinhloko okuhlukene, amapayipi angahlukaniswa ngezigaba ezilandelayo:
1. Amapayipi omanyolo anomfutho ophezulu we-GB6479-2000 angasetshenziswa ezitshalweni zamakhemikhali namapayipi anamazinga okushisa asukela ku--40 kuya ku-400 ℃ nezingcindezi ezisukela ku-10-32Mpa.
2. I-GB/T8163-2008 iyipayipi lensimbi elivamile elingenamthungo elifanele ukudlulisa uketshezi.
3. Amapayipi esakhiwo esijwayelekile i-GB/T8162-2008 kanye ne-GB/T8163 afaneleka ukwakhiwa okujwayelekile, amafreyimu okusekela iphrojekthi yobunjiniyela, ukucubungula ngomshini nokukhiqiza, njll.
4. Ipayipi likawoyela elingangeni manzi le-ISO11960 lisetshenziswa njengomthombo wokukha uwoyela noma igesi emithonjeni kawoyela negesi.
