Emkhakheni wokukhiqiza ngokunemba, ubuqotho nokunemba kwamathuluzi okulinganisa kubalulekile ekuqinisekiseni ikhwalithi yomkhiqizo wokugcina. Amapulatifomu e-granite, avame ukusetshenziswa njengesisekelo semishini yokulinganisa edidiyelwe (ama-CMM), amathuluzi okuhlola, kanye nokusethwa okuhlukahlukene komshini, kumele agcine ukunemba kwawo ngaphansi kwezimo ezahlukahlukene zomthwalo. Umthamo wokuthwala umthwalo walezi zinkundla awuyona imininingwane yobukhulu obufanayo, njengoba amapulatifomu enzelwe ukuhlangabezana nezidingo ezithile ngokusekelwe esisindweni okulindeleke ukuthi asithwale. Kusukela kumamodeli alula kuya kuzixazululo ezisindayo, ukuqonda umehluko womklamo kumapulatifomu e-granite kubalulekile ekuqinisekiseni ukuthi asebenza kahle kakhulu ezinhlotsheni ezahlukene zezimboni.
Amapulatifomu e-granite abalulekile ekuhlinzekeni indawo yokubhekisela ezinzile, futhi amandla awo okuthwala umthwalo abalulekile ekugcineni ukuthamba nokunciphisa ukuguquguquka ngesikhathi sokusetshenziswa. Lawa mapulatifomu kumele aklanywe futhi akhiwe ngezinto zokwakha, izakhiwo, kanye namasu okucubungula ahambisana nezinhlelo zawo ezihlosiwe. Kungakhathaliseki ukuthi ipulatifomu isekela izingxenye ezilula noma imishini esindayo, kubalulekile ukukhetha umklamo ofanele ukuqinisekisa ukunemba kwesikhathi eside.
Kumapulatifomu e-granite alula, ngokuvamile lawo angaphansi kwama-500 kg, umklamo ujikeleza ibhalansi yokunemba okuphezulu nokwakhiwa okulula. Lawa mapulatifomu asetshenziswa kakhulu ezindaweni lapho kudingeka khona ukunemba okuphezulu, kodwa isisindo sepulatifomu sidinga ukuncishiswa. Izinto ezifana ne-granite emnyama ye-mica ecolekile, enokuqukethwe kwe-quartz okungu-30% noma ngaphezulu, zivame ukusetshenziswa. Lezi zinto zinikeza ububanzi obuhle bokuxinana obungu-2.6–2.7g/cm², okuqinisekisa ukuqina ngenkathi kunciphisa isisindo. Ubukhulu bepulatifomu buvame ukuba phakathi kwama-50 nama-80 mm kumodeli engu-1m × 1m, futhi umklamo uhlanganisa isakhiwo esinezimbambo ezingenalutho ngaphansi. Njengoba izimbambo zihlukaniswe ngama-200–300mm futhi zinobubanzi obungu-30mm kanye nokuphakama okungu-40mm, lo mklamo unikeza ibhalansi efanele phakathi kwamandla nokunciphisa isisindo, okwenza kube lula ngama-30% kunezakhiwo eziqinile. Ngaphezu kwalokho, imvamisa ye-resonance yepulatifomu ingaphezu kwama-50Hz, okusiza ukugwema ukuphazamiseka okuvela ekudlidlizeni.
Ukunemba komklamo walezi zinkundla nakho kubalulekile. Ukuthamba kwendawo yokusebenza kuvame ukulawulwa kube ngaphansi kuka-0.005mm/100mm, okuqinisekisa ukuguquguquka okuncane ngisho nangaphansi kwemithwalo emaphakathi.amapulatifomu e-graniteZivame ukusetshenziswa ekuhlanganiseni amathuluzi okukhanya, ukulinganisa amathuluzi amancane, kanye nezinhlelo zokusebenza ezifanayo lapho ukuxhumana nepulatifomu kubalwa ngaphezu kuka-60% wendawo yonke yokuthwala, okuvimbela ingcindezi enkulu ezindaweni ezisendaweni.
Amapulatifomu aphakathi nendawo, asukela ku-500 kg kuya ku-5000 kg, aklanywe ngesethi ehlukile yezinto eziza kuqala. Ngenkathi egcina izinga eliphezulu lokunemba, la mapulatifomu kumele athwale imithwalo emikhulu. Kula mapulatifomu, i-granite ephakathi nendawo iyathandwa, ngokuvamile enokuqukethwe kwe-feldspar okungu-40%–50%. Ubuningi bukhushulwa bube ngu-2.7–2.8g/cm³, futhi ubukhulu bepulatifomu bukhushulwa bube ngu-100–150mm kumodeli engu-1m × 2m. Ingxenye engezansi inesakhiwo esiqiniswe ngegridi, lapho izimbambo eziyinhloko zingu-50mm ububanzi, kanti izimbambo eziwelayo zingu-30mm ububanzi, zakha igridi engu-100×100mm. Amaphuzu okucindezeleka azungezwe emakhoneni ukuze kuncishiswe ukugxilisa ingqondo. Lesi sakhiwo segridi siqinisekisa ukuthi ipulatifomu igcina amandla ayo futhi inciphisa ukugoba.
Ukuze kube nokunemba okwengeziwe, lawa mapulatifomu avame ukuba nezindawo zokufaka izintambo (12–16mm ububanzi) zokufakwa kwezinsimbi, kanye nesikhala sezikhala esisukela ku-100mm kuya ku-150mm. Izikhala zibekwe ukuze kuvinjelwe ubuthakathaka bamandla epulatifomu, ngebanga elincane elingama-30mm ukusuka ngaphansi. Ngesikhathi sokufakwa, izisekelo ezilungisekayo zisetshenziselwa ukusabalalisa umthwalo ngokulinganayo, ngamaphuzu amane okusekela ngemitha yesikwele, okuqinisekisa ukuthi ukuphambuka komthwalo kuhlala kungaphakathi kuka-5%. Lawa mapulatifomu avame ukusetshenziswa emishinini yokulinganisa ehlanganisiwe, ukuhlolwa kwesikhunta esiphakathi nendawo, kanye nezinhlelo zokusebenza ezifanayo, lapho ukuphambuka okuphezulu okuvunyelwe kungu-≤ L/10000 (L ubude bepulatifomu).
Amapulatifomu aqinile, aklanyelwe imithwalo engaphezu kuka-5000 kg, akhiwe ukuze amelane nokuguquguquka ngaphansi kwesisindo esikhulu. Lawa mapulatifomu enziwe nge-granite ecoarse-grain, enamakristalu e-quartz angaphezu kuka-2mm, futhi anobuningi obungaphezu kuka-2.8g/cm³. Amandla okucindezela ale nto ngokuvamile angaphezu kuka-200 MPa, futhi ubukhulu bala mapulatifomu busukela ku-200 kuya ku-300mm kumodeli engu-2m × 3m. Isakhiwo siqinile, sinesisekelo esijiyile (ubukhulu obungu-50mm) esixhumanisa nepulatifomu eyinhloko ngesisekelo esimise okweqanda esine-epoxy resin bonding (enamandla okusika ≥ 15 MPa).
Kumapulatifomu asebenza kanzima, ukufakwa kudinga ukulungiswa komhlabathi okuqondile. Isisekelo sekhonkrithi kufanele okungenani sibe ngu-300mm ubukhulu, sibe namapuleti ensimbi afakwe ngezinto ze-Q235. Phakathi kwesisekelo nepulatifomu, kusetshenziswa ungqimba lwerabha lwe-chloroprene oluyi-3mm ubukhulu ukuqinisekisa ukusatshalaliswa kokucindezeleka okufanayo. Isisekelo kumele sibe nomthamo wokuthwala umthwalo okungenani ongu-0.3 MPa. Lawa mapulatifomu asetshenziswa ezicelweni ezifana nokuhlolwa kwamathuluzi omshini osindayo kanye nokuhlelwa okukhulu kokukhipha, lapho ukuguqulwa kokuhamba kwesikhathi eside kufanele kuhlale ngaphansi kuka-0.002mm ngonyaka.
Izindinganiso zokuhlola zamapulatifomu e-granite ahlukene athwala umthwalo nazo ziyahlukahluka kakhulu. Amapulatifomu alula ahlolwa ngokudlidliza (imvamisa yokushanela engu-10-500Hz, ubukhulu obungu-0.1mm) ukuqinisekisa ukuthi akukho ukuzwakala okwenzekayo. Amapulatifomu aphakathi nendawo ahlolwa ngomthwalo ongaguquki ophindwe ka-1.2 amandla awo alinganisiwe, kanti ukuguquguquka akudluli ku-0.001mm ngemva kwamahora angu-24 okufakwa nokususwa komthwalo. Amapulatifomu anzima ahlolwa ukuthi amelana nokukhathala, ngemijikelezo engu-1000 yokukhipha umthwalo ku-80% womthwalo wawo olinganisiwe ukuqinisekisa ukuthi akukho mifantu evelayo, eqinisekiswa ngokutholwa kwamaphutha angena ngaphakathi.
Uma ukhetha ipulatifomu efanele ye-granite, kubalulekile ukufanisa umklamo nezidingo ezithile zohlelo lokusebenza. Ezimbonini ezidinga ukunemba okuphezulu kanye namandla okuthwala umthwalo osindayo, ukukhetha umklamo wepulatifomu ofanele kuqinisekisa ukusebenza kwesikhathi eside kanye nokuthembeka. I-ZHHIMG iyaqonda ukubaluleka kwezixazululo ezenziwe ngokwezifiso ezenzelwe ukuhlangabezana nezidingo ezihlukile zeklayenti ngalinye, inikeza uhla lwamapulatifomu e-granite anikeza ukunemba okuphezulu, ukuzinza, kanye nokuqina ngaphansi kwezimo ezahlukahlukene zokulayisha.
Kwa-ZHHIMG, sihlinzeka ngamapulatifomu amaningi e-granite, aklanyelwe ukuhlangabezana nezidingo zezimboni ezisukela ekusetshenzisweni komshini oqondile kuya ekuhlolweni okunzima. Amapulatifomu ethu aklanywe ngezindinganiso zekhwalithi ephezulu ukuqinisekisa ukusebenza okuhle kakhulu, anikeza kokubili ukunemba nokuthembeka, kungakhathaliseki ukuthi izidingo zokuthwala umthwalo zingakanani. Ukuzibophezela kwethu emisha kanye nekhwalithi kusivumela ukuthi sinikeze izixazululo ezihlala isikhathi eside, sikunikeze isisekelo esifanele sezidingo zakho zokukhiqiza ngokunemba.
