I-Silicon Carbide (SiC) iyindinganiso yemboni yezindawo zasolwandle ngenxa yobunzima bayo obungavamile kanye nokumelana nokuhlaselwa ngamakhemikhali kanye nokuguguleka okunamandla. Kuma-elastomer, i-Fluorocarbon (FKM/Viton) ichazwa kabanzi ngenxa yobubanzi bayo bokushisa kanye nokumelana nokungcola okusekelwe kuphethiloli okuvame ukutholakala emanzini angcolile, yize i-EPDM isadingeka ekusetshenzisweni kwamanzi ashisayo athile lapho uwoyela ungekho khona. Izinsimbi ezingagqwali ezimbili (njenge-SAF 2205) noma i-Titanium zivame ukuphoqelelwa izingxenye zensimbi ukuvimbela ukugoba okubangelwa yi-chloride.

Imiklamo yokuvala izimbobo yezidingo ezahlukene zephampu kanye nezikebhe

Ukwakheka kwesakhiwo sesivalo kuthinta kokubili ukusebenza kahle kokufakwa kanye nokuthembeka kokusebenza. Izivalo ze-cartridge zithandwa kakhulu ezindaweni zasolwandle ngoba zihlanganiswa kusengaphambili, zisethwe kusengaphambili, futhi zihlolwe ingcindezi efektri, okususa amaphutha okufakwa emakamelweni enjini yemikhumbi evalekile. Kuketshezi oluyingozi noma olubaluleke kakhulu, ukuhlelwa kwesivalo okuphindwe kabili (kungaba ukucindezela emuva kuya emuva noma i-tandem engacindezelwanga) kunikeza isithiyo sesibili sokuvimbela. Ngokuphambene nalokho, izivalo zezingxenye (njengemiklamo yesivalo esisodwa noma yesivalo samagagasi) zihlala zijwayelekile kumaphampu e-centrifugal asizayo lapho isikhala silinganiselwe khona futhi izindleko zangaphambilini zilawulwa ngokuqinile.

Izindlela zokuqhathanisa imininingwane zabathengi

Abathengi kumele bahlele imigomo yabo yokucacisa ukuze baqinisekise ukuthi kubhekiswana ngokunembile phakathi kwabaphakeli. Amaphuzu edatha abalulekile afaka ububanzi obuqondile bomgodi (ngokuvamile kusukela ku-20mm kuya ku-150mm wamaphampu asolwandle), umkhawulo we-Pressure-Velocity (PV) odingekayo, kanye nokuhambisana kophawu oluthile lwephampu. Amaqembu okuthenga kufanele agunyaze ukuthi abaphakeli bahlinzeke ngemidwebo yobukhulu eqinisekisa ukulingana okuqondile kwemishini ye-OEM, ukuqinisekisa ukuthi izivalo zokufaka esikhundleni zihambisana nembobo yendlu kanye nobude bokusebenza bokufakwa kokuqala.

Indlela Yokuhlola Abaphakeli

Ukuhlonza umlingani wokukhiqiza ofanelekayo kudinga ukuhlola ingqalasizinda yakhe yokukhiqiza, izinhlelo zokuphatha ikhwalithi, kanye nekhono lokwakha izivalo ezihlangabezana noma ezidlula izimfuneko ze-OEM. Ukuthola amasu kulesi sigaba kuncike kakhulu ekubonakaleni komhlinzeki kanye nekhono lobuchwepheshe.

Amandla okukhiqiza kanye nokuhambisana kwe-OEM

Umhlinzeki onekhono kumele abonise amakhono aqinile okusebenza ngomshini kanye nokubopha ukuze afinyelele ukuthamba kobuso bokuvala ngaphakathi kwamabhande okukhanya angu-2 kuya kwangu-3 (cishe u-0.0006mm kuya ku-0.0009mm). Abakhiqizi abasunguliwe abanolwazi lwamashumi eminyaka, njengalabo abasebenzisa izikhungo ezingaphezu kuka-3,000 square metres namaqembu obunjiniyela azinikele, bavame ukuhlinzeka ngamaphothifoliyo abanzi ahambisana ne-OEM. Laba baphakeli bangahlinzeka ngokushintshwa okuqondile kwemikhiqizo emikhulu yephampu yasolwandle efana ne-IMO, i-Alfa Laval, i-Grundfos, i-APV, i-Flygt, ne-Allweiler. Leli khono livumela amaqembu okuthenga ukuthi ahlanganise isisekelo sabathengisi bawo ngenkathi evikela izingxenye zokufaka ezifanelana nokubekezelelana okuqondile kwemishini yokuqala.

I-MOQ, ukusampula, ukupakisha, kanye nokusekelwa kwezingxenye ezisele

Amagama ezentengiselwano ahluka kakhulu ngokusekelwe kumodeli yokukhiqiza yomhlinzeki. Ngezimbobo zasolwandle ezihambisana ne-OEM ezijwayelekile, i-Minimum Order Quantities (MOQs) ngokuvamile isukela kumayunithi ayi-10 kuya kwangu-50. Kodwa-ke, ngezimbobo zekhatriji ezenziwe ngokwezifiso noma amasethi e-rotor akhethekile, abathengi kufanele baxoxisane ngama-MOQ aphansi (amayunithi angu-1 kuya kwangu-5) ukusekela ukuhlolwa kwe-pilot kanye ne-prototyping. Ukusekelwa okuphelele kwezingxenye ezisele nakho kubalulekile; abahlinzeki kufanele banikeze amakhithi okulungisa ahlanganisa ama-O-rings, izipringi, kanye nobuso. Izinqubomgomo zokuthatha amasampula kufanele zivumele abathengi ukuthi bahlole amayunithi okuqala ngaphambi kokuzibophezela ezinkontilekeni zevolumu.
