Umehluko entengo yemakethe phakathi kwamapayipi ensimbi angenamthungo anezindonga ezincane kanye namapayipi ensimbi angenamthungo anezindonga ezinkulu uncike kakhulu enqubweni yokukhiqiza, izindleko zezinto zokwakha, insimu yokufaka kanye nesidingo. Lokhu okulandelayo umehluko wawo oyinhloko ngentengo kanye nokuthuthwa:

1. Umehluko wentengo yemakethe
Ipayipi lensimbi elingenamthungo elinodonga oluncane:

Izindleko eziphansi: Ngenxa yobukhulu bodonga obuncane, kusetshenziswa izinto zokusetshenziswa ezimbalwa, kanti izindleko zokukhiqiza ziphansi kakhulu.

Kusetshenziswa kabanzi: Kusetshenziswa kakhulu ngezikhathi lapho kunezidingo eziphansi zamandla nokumelana nengcindezi, njengokwakha, ukuhlobisa, ukuthuthwa koketshezi, njll., lapho kunesidingo esikhulu semakethe.

Ukushintshashintsha kwentengo okuncane: Ngokuvamile, intengo izinzile futhi ithintwa kakhulu yimakethe yensimbi.

Ipayipi lensimbi elingenamthungo elinodonga olujiyile:

Izindleko eziphezulu: Ubukhulu bodonga bukhulu, kusetshenziswa izinto zokusetshenziswa ezengeziwe, futhi inqubo yokukhiqiza iyinkimbinkimbi, okuholela ezindleleni eziphakeme.

Izidingo zokusebenza okuphezulu: Ivame ukusetshenziswa emikhakheni enengcindezi ephezulu kanye nezidingo zamandla aphezulu esakhiwo, njengemishini yemishini, amakhemikhali kaphethroli, amabhoyila, njll., enezidingo eziphezulu zamandla okucindezela kanye nokumelana nokugqwala.

Intengo ephezulu kanye nokuguquguquka okukhulu: Ngenxa yesidingo esiqinile samapayipi ensimbi anodonga olujiyile emikhakheni ethile, intengo iyashintshashintsha kakhulu, ikakhulukazi lapho intengo yezinto zokusetshenziswa zensimbi ikhuphuka.
2. Izinyathelo zokuqapha zokuhamba
Ipayipi lensimbi elingenamthungo elinodonga oluncane:

Kulula ukukhuhla: Ngenxa yodonga oluncane lwepayipi, kulula ukukhuhla amandla angaphandle ngesikhathi sokuthuthwa, ikakhulukazi lapho kuhlanganiswa futhi kuhlanganiswa.
Vimbela imihuzuko: Ubuso bamapayipi anezindonga ezincane bonakaliswa kalula, futhi kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengokumboza ubuso ngendwangu yepulasitiki noma ezinye izinto zokuzivikela.
Ukubopha okuzinzile: Kuyadingeka ukusebenzisa amabhande athambile noma amabhande ensimbi akhethekile ukubopha ukuze ugweme ukuguquka komzimba wepayipi ngenxa yokuqina ngokweqile.
Ipayipi lensimbi elingenamthungo elinodonga olujiyile:

Isisindo Esinzima: Amapayipi ensimbi anodonga olujiyile ayasinda, futhi kudingeka imishini yokuphakamisa emikhulu ngesikhathi sokuthuthwa, futhi amathuluzi okuthutha kudingeka abe nomthamo owanele wokuthwala.
Ukufakwa kwe-stacking okuzinzile: Ngenxa yesisindo esinzima samapayipi ensimbi, ibhalansi kanye nokuqina kufanele kucatshangelwe ngesikhathi sokufakwa kwe-stacking ukuze kugwenywe ukugingqika noma ukugoba, ikakhulukazi ngesikhathi sokuthutha ukuze kuvinjelwe ukushelela noma ukushayisana.
Ukuphepha kwezokuthutha: Ngesikhathi sokuthuthwa ibanga elide, kufanele kuqashelwe kakhulu amathuluzi anjengezindwangu ezivimbela ukushelela kanye namabhulokhi okusekela phakathi kwamapayipi ensimbi ukuze kugwenywe umonakalo obangelwa ukungqubuzana kanye nokushayisana.
Intengo yamapayipi ensimbi angenamthungo asodongeni oluncane iphansi kakhulu, kodwa kufanele kuqashelwe ukuvimbela ukuguquka kanye nokulimala kwendawo ngesikhathi sokuthuthwa; kuyilapho intengo yamapayipi ensimbi angenamthungo asodongeni oluqinile iphakeme, futhi kufanele kuqashelwe ngokukhethekile ukuphepha, ukuzinza kanye nokuphathwa kwesisindo ngesikhathi sokuthuthwa. Kodwa-ke, amapayipi ensimbi angenamthungo anezinto ezikhethekile kanye nezincazelo kusadingeka ahlolwe ngempela.
Amapayipi amakhulu ensimbi angenamthungo eSanonpipe ahlanganisa amapayipi ebhoyila, amapayipi omanyolo, amapayipi kawoyela, kanye namapayipi okwakha.
