Ukucubungula okungaphezulu kwensimbi engagqwali
Ukucutshungulwa okungaphezulu kwensimbi engagqwali Cishe kunezinhlobo ezinhlanu eziyisisekelo zokucutshungulwa kwendawo engasetshenziselwa ukucutshungulwa kwensimbi engagqwali. Zingahlanganiswa futhi zisetshenziselwe ukuguqula imikhiqizo eminingi yokugcina. Izigaba ezinhlanu ukucutshungulwa kwe-rolling surface, inqubo ye-mechanical surface...Funda kabanzi -
Ukufakwa kwamapayipi ensimbi engenasici anezindonga ezincane
Lapho ubeka amapayipi ensimbi engagqwali anezindonga ezincane, kufanele afakwe ngemva kokuba umsebenzi womphakathi usuphelile. Ngaphambi kokufaka, okokuqala, hlola ukuthi indawo yembobo egodliwe ilungile yini. Uma ubeka amapayipi ensimbi engenasici anezindonga ezincane, ibanga eliphakathi kwezisekelo ezingaguquki akufanele libe likhulu...Funda kabanzi -
Umehluko phakathi kokugaya kwamakhemikhali, ukugaya nge-electrolytic kanye nokugaya ngomshini kwensimbi engagqwali
Umehluko phakathi kokugaya ngamakhemikhali, ukugaywa kwe-electrolytic kanye nokugaya okuwumshini kwensimbi engagqwali (1) Ukupholisha ngamakhemikhali nokupholishwa ngomshini kuhluke kakhulu “Ukupholishwa ngamakhemikhali” kuyinqubo lapho izingxenye ezincane ze-convex ezingaphezulu ezizopholishwa zi...Funda kabanzi -
304 indlela yokukhiqiza ipayipi lensimbi engagqwali
Ngokwezindlela ezihlukene zokukhiqiza, ingahlukaniswa ngamashubhu agoqiwe ashisayo, amashubhu agoqiwe abandayo, amashubhu adonswa abandayo, amashubhu akhishwe, njll. 1.1. Amapayipi ensimbi engenamthungo agingqiwe ashisayo ngokuvamile akhiqizwa ezigayweni eziginqikayo zamapayipi. Ishubhu eliqinile liyahlolwa futhi lihlanzwe ngaphandle ...Funda kabanzi -
Plastic camera steel pipe ngaphakathi nangaphandle
Kokubili izindonga zangaphakathi nezangaphandle zepayipi lensimbi elakhiwe ngepulasitiki zimbozwe nge-epoxy resin, indawo engaphezulu ibushelelezi, ukumelana noketshezi kuyancishiswa, izinga lokugeleza liyakhula, asikho isikali esakhiwe, futhi ama-microorganisms ngokuvamile awakhuli. Impilo yesevisi yepayipi lamanzi okulwa nomlilo (igesi)...Funda kabanzi -
Izici umkhiqizo plastic camera steel pipe ngaphakathi nangaphandle
Izici zomkhiqizo wepayipi lensimbi elakhiwe ngepulasitiki ngaphakathi nangaphandle 1. Inhlanzeko, engenabuthi, engangcolisi, engeyona i-microorganism, eqinisekisa ikhwalithi yoketshezi 2. Ukumelana nokugqwala kwamakhemikhali, ukugqwala kwenhlabathi kanye ne-marine biological, ukuhlukaniswa kwe-cathodic 3. Inqubo yokufaka iwukuba ovuthiwe, olungele...Funda kabanzi
