Izikhwama zephepha eziphathwa ngesandla ngokuvamile zenziwe ngephepha lezinga eliphezulu nelezinga eliphezulu, i-kraft paper, amakhadibhodi amhlophe ambozwe, i-copperplate, amakhadibhodi amhlophe, njll. Zilula, zilula, futhi zinokuphrinta okuhle ngamaphethini amahle. Zisetshenziswa kakhulu ekufakweni kwezimpahla ezifana nezingubo, ukudla, izicathulo, izipho, ugwayi notshwala, kanye nemithi. Ngesikhathi sokusetshenziswa kwezikhwama ze-tote, kuvame ukuba nenkinga yokuqhekeka ngezansi noma izigxobo eziseceleni zesikhwama, ezithinta kakhulu impilo yesevisi yesikhwama sephepha kanye nesisindo kanye nenani lezinto ezingabamba. Ukwenzeka kokuqhekeka ekubekweni uphawu kwezikhwama zephepha eziphathwa ngesandla ikakhulukazi kuhlobene namandla okunamathela okubekwa uphawu. Kubaluleke kakhulu ukucacisa amandla okunamathela okuvalwa kwezikhwama zephepha eziphethwe ngesandla ngokusebenzisa ubuchwepheshe bokuhlola.
Amandla okunamathisela okuvalwa kwezikhwama zephepha eziphathwa ngesandla acaciswe ngokuqondile ku-QB/T 4379-2012, edinga amandla okunamathisela okuvala angekho ngaphansi kuka-2.50KN/m. Amandla okunamathisela okuvala uphawu azonqunywa indlela yokuqina kwesivinini esingaguquki ku-GB/T 12914. Thatha izikhwama ezimbili zesampula futhi uhlole amasampula angu-5 kusukela ekugcineni okuphansi kwesikhwama ngasinye nohlangothi. Lapho kwenziwa amasampula, kuhle ukubeka indawo yokubopha phakathi nesampula. Uma ukuvala kuqhubeka futhi impahla iphuka, amandla okuvala avezwa njengamandla aqinile wento ngesikhathi sokuphuka. Bala isilinganiso se-arithmetic samasampuli angu-5 ekugcineni okuphansi namasampuli angu-5 eceleni, futhi uthathe okuphansi kokubili njengomphumela wokuhlola.
Amandla okunamathela angamandla adingekayo ukuze kuphulwe uphawu lobubanzi obuthile. Leli thuluzi lamukela isakhiwo esime mpo, futhi i-clamping fixture yesampula ilungiswa nge-clamp ephansi. I-clamp engenhla iyasuswa futhi ixhunywe kunzwa yenani lamandla. Phakathi nokuhlolwa, iziphetho ezimbili zamahhala zesampula ziboshelwa kuzimpimpi ezingaphezulu neziphansi, futhi isampula iyahlutshwa noma yelulwe ngesivinini esithile. Inzwa yamandla irekhoda inani lamandla ngesikhathi sangempela ukuze ithole amandla okunamathela esampula.
1. Ukusampula
Thatha izikhwama ezimbili zamasampula bese uhlola amasampula angu-5 engxenyeni engezansi nehlangothini lwesikhwama ngasinye. Ububanzi besampula kufanele bube ngu-15 ± 0.1mm futhi ubude kufanele okungenani bube ngu-250mm. Lapho kwenziwa isampula, kuhle ukubeka ingcina phakathi nesampula.
2. Setha imingcele
(1) Setha isivinini sokuhlola sibe ngu-20 ± 5mm/min; (2) Setha ububanzi besampula ku-15mm; (3) Isikhala phakathi kwezinsimbi sisethwe ku-180mm.
3. Beka isampula
Thatha isampula elilodwa bese ubopha iziphetho zombili zesampula phakathi kwama-clamp angaphezulu naphansi. I-clamp ngayinye kufanele ibambe ngokuqinile ububanzi obugcwele besampula emgqeni oqondile ngaphandle kokulimala noma ukushelela.
4. Ukuhlola
Cindezela inkinobho 'yokusetha kabusha' ukuze usethe kabusha ngaphambi kokuhlola. Cindezela inkinobho ethi "Hlola" ukuze uqale ukuhlola. Ithuluzi libonisa inani lamandla ngesikhathi sangempela. Ngemuva kokuthi ukuhlolwa sekuqediwe, i-clamp ephezulu isethwe kabusha futhi isikrini sibonisa imiphumela yokuhlolwa kwamandla okunamathela. Phinda izinyathelo 3 no-4 kuze kube yilapho wonke amasampula ama-5 esehloliwe. Cindezela inkinobho ethi "Izibalo" ukuze ubonise imiphumela yezibalo, ehlanganisa isilinganiso, esiphezulu, esincane, ukuchezuka okujwayelekile, kanye ne-coefficient yokuhluka kwamandla okunamathela.
5. Imiphumela yokuhlola
Bala isilinganiso se-arithmetic samasampuli angu-5 ekugcineni okuphansi namasampuli angu-5 eceleni, futhi uthathe okuphansi kokubili njengomphumela wokuhlola.
Isiphetho: Amandla okunamathela ophawu lwesikhwama sephepha esibanjwe ngesandla siyisici esibalulekile esinquma ukuthi sijwayele ukuqhekeka ngesikhathi sokusetshenziswa. Ngokwezinga elithile, inquma isisindo, ubuningi, nempilo yesevisi yomkhiqizo isikhwama sephepha esiphathwa ngesandla esingamelana nayo, ngakho-ke kufanele sithathwe ngokungathi sína.
