蘇州維修布(bu)(bu)氏(shi)(shi)硬(ying)(ying)度(du)(du)(du)(du)(du)計(ji)(ji) 常用的(de)金(jin)屬(shu)材(cai)料的(de)硬(ying)(ying)度(du)(du)(du)(du)(du)檢測(ce)試(shi)驗(yan)(yan)機(ji)有(you)布(bu)(bu)氏(shi)(shi)、里(li)氏(shi)(shi)、洛氏(shi)(shi)硬(ying)(ying)度(du)(du)(du)(du)(du)計(ji)(ji)等。布(bu)(bu)氏(shi)(shi)硬(ying)(ying)度(du)(du)(du)(du)(du)計(ji)(ji)主要用于組織不(bu)均勻的(de)鍛(duan)鋼和(he)鑄(zhu)鐵的(de)硬(ying)(ying)度(du)(du)(du)(du)(du)測(ce)試(shi)，鍛(duan)鋼和(he)灰鑄(zhu)鐵的(de)布(bu)(bu)氏(shi)(shi)硬(ying)(ying)度(du)(du)(du)(du)(du)與拉(la)伸試(shi)驗(yan)(yan)有(you)著較(jiao)好的(de)對應關(guan)系。里(li)氏(shi)(shi)硬(ying)(ying)度(du)(du)(du)(du)(du)計(ji)(ji)適用于金(jin)屬(shu)材(cai)料的(de)快速硬(ying)(ying)度(du)(du)(du)(du)(du)測(ce)試(shi)，特別適宜對大型零部件及(ji)不(bu)可(ke)拆卸部件的(de)現場硬(ying)(ying)度(du)(du)(du)(du)(du)測(ce)試(shi)。洛氏(shi)(shi)硬(ying)(ying)度(du)(du)(du)(du)(du)試(shi)驗(yan)(yan)采用了3種壓(ya)頭(tou)，6種試(shi)驗(yan)(yan)力，根據金(jin)屬(shu)材(cai)料材(cai)質、硬(ying)(ying)度(du)(du)(du)(du)(du)范圍及(ji)尺寸的(de)不(bu)同，共有(you)15個標尺可(ke)供選擇。

蘇州維(wei)修維(wei)氏硬(ying)度(du)計 硬(ying)度(du)計的種類(lei)較多，在工礦企事業和科研單位中(zhong)應用普遍的以金(jin)屬(shu)洛氏、布氏、維(wei)氏硬(ying)度(du)計為(wei)主， 其(qi)中(zhong)金(jin)屬(shu)洛氏和金(jin)屬(shu)布氏硬(ying)度(du)計相對于(yu)金(jin)屬(shu)維(wei)氏硬(ying)度(du)計結構簡單

蘇州維(wei)修洛(luo)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)計： 常(chang)用(yong)的(de)金屬材(cai)料(liao)的(de)硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)檢測試(shi)(shi)驗(yan)機有(you)布(bu)氏、里(li)氏、洛(luo)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)計等。布(bu)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)計主要用(yong)于(yu)組織(zhi)不均(jun)勻(yun)的(de)鍛(duan)鋼和(he)鑄鐵的(de)硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)測試(shi)(shi)，鍛(duan)鋼和(he)灰(hui)鑄鐵的(de)布(bu)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)與拉伸試(shi)(shi)驗(yan)有(you)著較(jiao)好的(de)對應(ying)關系。里(li)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)計適用(yong)于(yu)金屬材(cai)料(liao)的(de)快(kuai)速硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)測試(shi)(shi)，特(te)別適宜對大(da)型零部(bu)件(jian)及不可拆卸部(bu)件(jian)的(de)現場(chang)硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)測試(shi)(shi)。洛(luo)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)試(shi)(shi)驗(yan)采用(yong)了(le)3種壓頭，（洛(luo)氏硬(ying)(ying)(ying)度(du)(du)(du)(du)(du)(du)計維(wei)修）

蘇州維修(xiu)里氏硬度(du)計(ji) 硬度(du)值(zhi)不準確(que)：有(you)(you)二(er)種(zhong)情(qing)況導致測(ce)試硬度(du)不準確(que)，如果所(suo)用的壓(ya)(ya)頭(tou)(tou)是(shi)金鋼石(shi)壓(ya)(ya)頭(tou)(tou)，首(shou)先(xian)用指(zhi)甲(jia)表(biao)面輕(qing)(qing)輕(qing)(qing)與(yu)壓(ya)(ya)頭(tou)(tou)頂(ding)部磨擦一(yi)二(er)下，觀察指(zhi)甲(jia)有(you)(you)沒劃出深痕(hen)跡，有(you)(you)深痕(hen)跡表(biao)示(shi)壓(ya)(ya)頭(tou)(tou)已(yi)損壞，反(fan)之(zhi)為(wei)好(hao)的壓(ya)(ya)頭(tou)(tou)。第二(er)種(zhong)情(qing)況就是(shi)儀器微(wei)調(diao)處未(wei)調(diao)好(hao)，打開(kai)硬度(du)計(ji)頂(ding)蓋，用一(yi)字(zi)螺絲刀把頂(ding)針部二(er)顆(ke)螺絲調(diao)松，然后把微(wei)調(diao)鐵塊向前調(diao)節使硬度(du)值(zhi)調(diao)高，反(fan)之(zhi)為(wei)調(diao)低。
