Kwesivumelwano se-NPT kanye izici zayo

Icubungula steel induku noma tube ngokuyenza Ukuchusha ithuluzi elikhethekile okuthiwa i uxhumano kochungechunge. It isetshenziswa nati, ngezikulufo, amabhawodi, abese esetshenziswa ukuxhuma izingxenye emincane nemikhulu ehlukahlukene, futhi intambo ipayipi isetshenziswa ukufakwa kwepayipi.

Izakhi eziyinhloko zalolu hlobo kwakwakhe detachable kuyinto iphimbo layo, iphrofayli, we anemifantu ukujula ububanzi we zangaphakathi nezangaphandle. Amaphrofayli zihlukaniswe izinhlobo eziningana: trapezoid, ntathu, unxande nabanye. Kuyini iphrofayli? Uma senza cross-section, bese uthola ifomu unephrofayela.

Ufuna ukuthi injongo, into ngeke sisetshenziswe kuchungechunge ipayipi kungaba kwesobunxele noma kwesokudla. Futhi, zingahlukaniswa zibe akhethekile dunnage.

Uhlobo eyinhloko ekulungiseni compounds kuyinto iphrofayela elingunxantathu, nokuxhumana ekhethekile - elingunxande, futhi eziningi nezinye izinhlobo amaphrofayli.

Carving, usebenzile phezu ngezikulufo nezihluthulelo, amantongomane - unxantathu, ngoba isetshenziselwa fasteners. Ibanga phakathi crests noma emikhombeni we izisekelo ezimbili of ematfuba ukuvala ngokuthi isinyathelo. I ka ekhuthaza kangakanani ibanga kusuka phansi kuze kube seqophelweni eliphezu kwekhoyili.

Ukubeka ipayipi intambo noma ntathu, kuyinto intshi imethrikhi. Ngokuvamile, kuba iziqobosho oyinhloko insimbi yezimoto. Diameters, kokubili ngaphakathi nangaphandle, kuthiwa ulinganiswa ngamamilimitha, futhi step threaded, ngaphandle amamilimitha angu, ngisho ngamasheya yayo.

Kodwa ipayipi intshi ngentambo ine engela 55 degrees, nakuba iphrofayli kuyafana ukuthi we-metric. umehluko wabo ukuthi izilinganiso zenzeka amayintshi kunokuba amamilimitha angu ngenxa iphimbo emikhulu.

Uma ufaka amapayipi amapayipi asetshenziswa nezingxenye nge intshi threaded. Nanguya yasibamba nogwali. On amapayipi uma sicabangela iqiniso lokuthi Ukujula kwawo kulawulwa ukushuba of ipayipi izindonga, izindikimba ezincane. Kodwa futhi ngenxa inombolo enkulu ematfuba - uxhumano baqaphe. Kodwa ukuze zezakhi ezingaphezu esitebeleni efanelekayo ophahleni kokungathembeki ngentambo, okuyinto, njengoba kuboniswe ngenhla, uthathe imishudo, ngezikulufo, amantongomane, wenza metal okuqinile.

Ukubeka ipayipi ngentambo, ngaphezu ahlabayo othomathikhi, kungashiwo usike ngesandla nokusetshenziswa amadayisi. Plates nazo ihlukaniswe izinhlobo, kuya ngedivayisi yabo. Ziyakwazi prismatic, nxazonke, beya futhi lonke.

Ngokwesibonelo, ngokuhambisa esifa, ukusika ngentambo umnyuziki kungavimbela ukuhlukahluka encane ubukhulu metallic induku. Ukusebenzisa wonke round kufa, ngeziphambeko ububanzi kakade kungamukeleki.

Threaded phezu ipayipi kanje: kubalulekile ukuba ibambe thwi ukufaka futhi uvikelekile ku workpiece, futhi usebenzisa die isiyingi, kudlule obuphelele kuhlelwe ngesikhathi. Uma zisetshenziswa khona ngokuhambisa amapuleti, ukuzilimaza zizokwenzeka maqembu amabili noma amathathu.

Lapho ukusika ilungelo isikulufa uxhumano afe isitokwe kufanele rotated kwesokunene nezinhlanu ngakwesokunxele ukuzisika - ngakwesobunxele, kuyilapho ungakhohlwa ukwenza ambalwa ematfuba emuva ukuze kususwe. Lapho konke usulungile, kungaba ihlolwe ne nati usizo ukugoqa.

Ngo inqubo ukusika steel pipe ngentambo izakhi futhi ngokwalo die eshubile. Ukuze ukusetshenziswa sulfofrezol yabo Ukupholisa noma iphele uwoyela. Ukuze Ukupholisa cast iron kuyinto turpentine kangcono.

I ohlobo yangaphakathi bafa empompini. Ngendlela efanayo it is abethela kuheleza ingxenye, futhi empompini imbobo kuqala sekuphelile nokubala. Ngemva ukususwa ungqimba metal, ukusebenzisa ompompi wesibili nowesithathu, usike ematfuba seluvele ligcwele. Njalo qinisekisa ukuthi yokuthi eksisi emgodini kampompi kanye nomdlalo. Ngezikhathi ezithile, uyasikrufulula Thepha kolunye uhlangothi ¼ ujike ukususa chips.
