Umehluko enanini lemakethe phakathi kwamapayipi ensimbi angenamthungo anezindonga ezincane anezindonga eziwugqinsi ngokuyinhloko kuncike enqubweni yokukhiqiza, izindleko zempahla, indawo yokufakwa kwesicelo kanye nesidingo. Okulandelayo umehluko omkhulu wentengo nezokuthutha:

1. Umehluko wentengo yemakethe
Ipayipi lensimbi engenamthungo enezindonga ezincane:

Izindleko eziphansi: Ngenxa yokuqina kodonga oluncane, kusetshenziswa izinto ezingavuthiwe ezincane, futhi izindleko zokukhiqiza ziphansi.

Kusetshenziswa kakhulu: Isetshenziswa kakhulu ezikhathini ezinezidingo eziphansi zamandla nokumelana nengcindezi, njengokwakhiwa, ukuhlobisa, ukuthutha okuwuketshezi, njll., nesidingo esikhulu semakethe.

Ukushintshashintsha kwamanani amancane: Ngokuvamile, intengo izinzile futhi ithinteka kakhulu emakethe yensimbi.

Ipayipi lensimbi eliqinile elinezindonga:

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

Izidingo zokusebenza okuphezulu: Okuvame ukusetshenziswa emikhakheni enengcindezi ephezulu kanye nezidingo zamandla aphezulu esakhiwo, njengemishini yemishini, amakhemikhali e-petrochemicals, ama-boilers, njll., anezidingo eziphezulu zamandla okucindezela kanye nokumelana nokugqwala.

Intengo ephezulu kanye nokuguquguquka okukhulu: Ngenxa yesidingo esiqinile samapayipi ensimbi anezindonga eziwugqinsi emikhakheni ethile, intengo ishintshashintsha kakhulu uma kuqhathaniswa, ikakhulukazi uma intengo yezinto zokusetshenziswa zensimbi ikhuphuka.
2. Izinyathelo zokuqapha ezokuthutha
Ipayipi lensimbi engenamthungo enezindonga ezincane:

Kulula ukukhubazeka: Ngenxa yodonga oluncane lwepayipi, kulula ukukhubaza amandla angaphandle ngesikhathi sokuthutha, ikakhulukazi uma uhlanganisa nokupakisha.
Vimbela ukuklwebheka: Ingaphezulu lamapayipi anezindonga ezincane alimala kalula, futhi kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengokumboza indawo engaphezulu ngendwangu yepulasitiki noma ezinye izinto zokuzivikela.
Ukubopha okuzinzile: Kuyadingeka ukusebenzisa amabhande athambile noma amabhande ensimbi akhethekile ukuze kuhlanganiswe ukuze kugwenywe ukuguquguquka komzimba wepayipi ngenxa yokuqina ngokweqile.
Ipayipi lensimbi eliqinile elinezindonga:

Isisindo esisindayo: Amapayipi ensimbi anezindonga eziwugqinsi ayasinda, futhi imishini emikhulu yokuphakamisa iyadingeka ngesikhathi sokuthutha, futhi amathuluzi okuthutha adinga ukuba nomthamo owanele wokuthwala.
Ukupakisha okuzinzile: Ngenxa yesisindo esinzima samapayipi ensimbi, ibhalansi nokuzinza kufanele kucatshangelwe ngesikhathi sokupakishwa ukuze kugwenywe ukugingqika noma ukugoqa, ikakhulukazi ngesikhathi sokuthutha ukuze kuvinjelwe ukushelela noma ukungqubuzana.
Ukuphepha kwezokuthutha: Ngesikhathi sokuthutha okude, ukunakwa okukhethekile kufanele kukhokhwe kumathuluzi afana nama-anti-slip pads kanye namabhulokhi okusekela phakathi kwamapayipi ensimbi ukuze kugwenywe umonakalo obangelwa ukungqubuzana nomthelela.
Intengo yamapayipi ensimbi engenamthungo anezindonga ezincane iphansi, kodwa kufanele kuqashelwe ukuvimbela ukuwohloka nokonakala kwendawo ngesikhathi sokuthutha; kuyilapho intengo yamapayipi ensimbi angenamthungo anezindonga eziwugqinsi iphezulu, futhi ukunaka okukhethekile kufanele kukhokhwe ekuphepheni, ekuzinzeni nasekulawuleni isisindo ngesikhathi sokuthutha. Kodwa-ke, amapayipi ensimbi angenamthungo anezinto ezikhethekile kanye nokucaciswa kwawo kusadingeka ukuthi ahlolwe ngempela.
Amapayipi ensimbi angenamthungo eSanonpipe ahlanganisa amapayipi abhayela, amapayipi kamanyolo, amapayipi kawoyela, namapayipi esakhiwo.
