Kungani imishini yokuqeda imvamisa ephezulu udinga ukulungiswa?

Ukuze kuqinisekiswe ikhwalithi yemishini yokucisha imvamisa ephezulu, okokusebenza ngakunye kuzofakwa futhi kulungiswe, bese kunamathiselwa imanuwali nezinye izinto ezihlobene nazo, zipakishwe ebhokisini nangaphandle kwendawo yokugcina impahla, bese zithunyelwa kuzo zonke izingxenye zezwe. . Ulwazi lwemishini ngayinye luyatholakala ukuze luphenywe. Siyakwamukela ukuvakashela inkampani yethu.

Kungani imishini yokuqinisa imvamisa ephezulu idinga ukulayishwa ukuze ihlolwe?

Uma kungekho mthwalo, i-inductance izoshintsha ngokushesha ngemva kokuba umthwalo ubekwe kudatha etholwe ukuhlolwa kwamandla. Ngalesi sikhathi, idatha etholwe ukuhlolwa kwemishini yokucisha imvamisa ephezulu ihluke kakhulu esikhathini esingalayishiwe, futhi isu nalo alihambisani. Ukuze kuqinisekiswe ukunemba kwedatha yemishini Ngakho-ke, okokusebenza kokuqina kwemvamisa ephezulu kumele kulayishwe futhi kuhlolwe.

Uma nje ukupholisha kwenziwa kahle, ungqimba oluqinile lungabonakala ngokucacile ngemva kokupholisha. Ezinye izinto ezisetshenziswayo ziqhunyiswa ngesanti ngemva kokucisha imvamisa yamaphakathi, bese zihlanzwa ngamanzi kampompi, futhi ungqimba oluqinile oluqinile lungahlanzwa. Ingabonakala vele ngemva kokugqwala ngesisombululo se-nitric acid alcohol esingu-4%.

Uma ingxenye incane, ayilungisi ingxenye. Sibopha izingxenye ngamapulangwe futhi sizibeke endaweni ehambisanayo ye-loop yokungeniswa. Thembela ekusebenzeni okwenziwa ngesandla, yizwa ukuthi izinga lokushisa lilungile, futhi wenze umsebenzi wokucisha uwedwa. Izingxenye eziningi azinayo imfuneko yokujula kongqimba oluqinile, futhi izingxenye ezimbalwa kakhulu ezidingayo. Ukujula kongqimba oluqinile kungu-0.5mm~1mm. Ngakho-ke, ungqimba oluqinile lwengxenye ngayinye lungase luhluke ekusebenzeni okwenziwa ngesandla. Umumo ukhethekile kancane, ungalinganiswa kuphela ngongqimba oluqinile lwebhulokhi yokuhlola.

Ukwengeza, ngokwezinga likazwelonke le-GB/T5617-2005, ubulukhuni bokugcina bungama-80% wobunzima obuncane obudingekayo bengxenye. Ukuqonda kwami ​​​​kucacisa kuphela umqondo wokuqina kokugcina, futhi akubonisi ukuthi u-80% wobunzima obuncane ukujula kongqimba oluqinile.

Ukuqonda kwe-GB/T5617-2005: Kala ukusuka phezulu ukuya ku-80% womkhawulo ophansi wobunzima obudingekayo ngomdwebo. Isibonelo, uma imfuneko yokuqina ingu-HRC58—61, kufanele ikalwe ibe ngu-80% we-HRC58.

Umkhawulo ophansi wokuqina kobuso kufanele uqale uguqulwe ube ubulukhuni be-Vickers, okungukuthi, ukuqina komkhawulo=ukuqina komkhawulo ophansi×0.80=664HV×0.80=531HV, okungukuthi, ukujula kongqimba oluqinile olusebenzayo lwalo mkhiqizo ngemva kokuqina kokungeniswa kuvela ingaphezulu kuya kokuqina Kweleya eliqinile kuya ekujuleni kwangempela kokuthi 531HV. Uma kuwukuhlolwa kwekhwalithi yokugcina kanye nokulamula, kufanele kube indlela yokuqina.
