活塞桿鍍硬鉻的工藝特點

 1)陰極(ji)電流達25%～35%,沉積速度很快;

 2)鍍層硬度(du)高(900～1200HV),呈均勻密集的網狀裂紋,耐(nai)(nai)磨(mo)性能好(hao)；能產生微(wei)裂紋，微(wei)裂紋數可(ke)達(da)800-2000條／厘米（根(gen)據需要調(diao)節），提(ti)高抗(kang)腐蝕能力。活塞桿耐(nai)(nai)鹽霧(wu)可(ke)達(da)500小(xiao)時以(yi)上(shang)。減(jian)震器桿耐(nai)(nai)鹽霧(wu)500小(xiao)時以(yi)上(shang)。

 3)鍍(du)液(ye)分散能力好,鍍(du)層厚度均(jun)勻,不易產(chan)生粗糙皰瘤現象,鉻層外觀(guan)青亮平滑；

 4)鍍層與基(ji)體結合(he)力強,前處(chu)理與傳統工(gong)藝相似,操作比傳統工(gong)藝容易； 

 5)鍍液中三價鉻含量(liang)允許范(fan)圍寬,通常不需要(yao)停產電解處理三價鉻；

 6)鍍液不(bu)含氟化(hua)物,不(bu)含稀土元素,工件無低電(dian)區(qu)的腐蝕。

往復泵活塞桿檢修的標準

 一種(zhong)活(huo)(huo)塞(sai)桿(gan)推進式(shi)錨桿(gan)鉆(zhan)機(ji)(ji)，該(gai)鉆(zhan)機(ji)(ji)的(de)(de)(de)氣缸(gang)(gang)組件中活(huo)(huo)塞(sai)桿(gan)兩(liang)(liang)(liang)端(duan)(duan)(duan)端(duan)(duan)(duan)蓋(gai)的(de)(de)(de)中心(xin)(xin)分別鉆(zhan)一通(tong)孔(kong)(kong)(kong)(kong)Ｃ和(he)(he)Ｄ，將(jiang)氣缸(gang)(gang)組件旋轉(zhuan)１８０度(du)，其一端(duan)(duan)(duan)用(yong)(yong)(yong)過(guo)(guo)渡(du)套將(jiang)機(ji)(ji)頭(tou)(tou)和(he)(he)活(huo)(huo)塞(sai)桿(gan)銜(xian)接(jie)，另一端(duan)(duan)(duan)用(yong)(yong)(yong)底板（９）。過(guo)(guo)渡(du)套外形是兩(liang)(liang)(liang)個直徑(jing)不同(tong)(tong)的(de)(de)(de)圓(yuan)柱，用(yong)(yong)(yong)臺階(jie)過(guo)(guo)渡(du)，兩(liang)(liang)(liang)端(duan)(duan)(duan)是直徑(jing)不同(tong)(tong)的(de)(de)(de)同(tong)(tong)心(xin)(xin)盲孔(kong)(kong)(kong)(kong)，兩(liang)(liang)(liang)盲孔(kong)(kong)(kong)(kong)的(de)(de)(de)底部中心(xin)(xin)有一通(tong)氣孔(kong)(kong)(kong)(kong)Ｂ，并在兩(liang)(liang)(liang)盲孔(kong)(kong)(kong)(kong)底部沿圓(yuan)周均布和(he)(he)活(huo)(huo)塞(sai)桿(gan)端(duan)(duan)(duan)蓋(gai)上(shang)(shang)的(de)(de)(de)螺(luo)紋孔(kong)(kong)(kong)(kong)數相同(tong)(tong)的(de)(de)(de)通(tong)孔(kong)(kong)(kong)(kong)，過(guo)(guo)渡(du)套經過(guo)(guo)螺(luo)栓和(he)(he)活(huo)(huo)塞(sai)桿(gan)上(shang)(shang)的(de)(de)(de)端(duan)(duan)(duan)蓋(gai)銜(xian)接(jie)；過(guo)(guo)渡(du)套的(de)(de)(de)大端(duan)(duan)(duan)和(he)(he)機(ji)(ji)頭(tou)(tou)的(de)(de)(de)內圓(yuan)間(jian)隙配合(he)，經過(guo)(guo)卡環用(yong)(yong)(yong)螺(luo)栓螺(luo)母銜(xian)接(jie)。該(gai)鉆(zhan)機(ji)(ji)能(neng)夠經過(guo)(guo)固定(ding)外缸(gang)(gang)停止多角度(du)鉆(zhan)孔(kong)(kong)(kong)(kong)；由于底板和(he)(he)氣缸(gang)(gang)外缸(gang)(gang)之間(jian)的(de)(de)(de)密(mi)封(feng)，能(neng)夠阻止泥土進入氣缸(gang)(gang)間(jian)隙，延長了(le)多級(ji)氣缸(gang)(gang)的(de)(de)(de)運用(yong)(yong)(yong)壽命。

高頻活塞桿

 高(gao)(gao)頻(pin)淬(cui)火原理：將(jiang)(jiang)工(gong)件放在用空心銅管(guan)繞成(cheng)的感應(ying)器內，通入高(gao)(gao)頻(pin)交流電后(hou)，在工(gong)件表(biao)面形成(cheng)同頻(pin)率的的感應(ying)電流，將(jiang)(jiang)零(ling)件表(biao)面或局(ju)部迅(xun)速(su)加(jia)熱（幾秒鐘內即可(ke)升(sheng)溫(wen)(wen)至800～1000℃，心部仍接近室溫(wen)(wen)）若干秒鐘后(hou)迅(xun)速(su)立(li)即噴(浸)水冷卻(que)（或噴浸油冷卻(que))完(wan)成(cheng)浸火工(gong)作，使工(gong)件表(biao)面或局(ju)部達到相應(ying)的硬度要求。

 感應加(jia)熱熱處理的設(she)備(bei)主(zhu)要由電(dian)(dian)源(yuan)(yuan)設(she)備(bei)、淬火機(ji)床和感應器組(zu)成。電(dian)(dian)源(yuan)(yuan)設(she)備(bei)的主(zhu)要作用(yong)是(shi)輸(shu)出(chu)頻率適宜的交變(bian)電(dian)(dian)流。高頻電(dian)(dian)流電(dian)(dian)源(yuan)(yuan)設(she)備(bei)有電(dian)(dian)子管高頻發生器和可控硅變(bian)頻器兩種(zhong)。中頻電(dian)(dian)流電(dian)(dian)源(yuan)(yuan)設(she)備(bei)是(shi)發電(dian)(dian)機(ji)組(zu)。一(yi)(yi)般電(dian)(dian)源(yuan)(yuan)設(she)備(bei)只能輸(shu)出(chu)一(yi)(yi)種(zhong)頻率的電(dian)(dian)流,有些設(she)備(bei)可以改變(bian)電(dian)(dian)流頻率，也可以直接用(yong)50赫的工頻電(dian)(dian)流進(jin)行感應加(jia)熱。
