意大利杰佛倫Gefran電子尺現貨
Gefran電子尺實際上是一種直線位移傳感器，可量測位移量，并以電阻方式作輸出。Gefran電子尺適用于注塑機，木工機械，印刷機，噴涂，機床，機器人，工程監測電腦控制運動器械等需要測量位移的場合。
Gefran電子(zi)尺常見故障及處(chu)理(li)方法(fa)
Gefran電子尺(chi)(chi)實際上就(jiu)是一個滑(hua)動變(bian)阻器,是作為分壓(ya)器使(shi)用 ,以相(xiang)對(dui)(dui)電壓(ya)來顯(xian)示所測(ce)量位置的實際位置。因此,就(jiu)對(dui)(dui)Gefran電子尺(chi)(chi)提出了幾點要求:
1、Gefran電(dian)子尺供電(dian)電(dian)壓要穩定(ding),工業電(dian)源要求+0.1%的(de)(de)(de)穩定(ding)性,比如基準電(dian)壓10V ,允許有(you)+0.01V的(de)(de)(de)波(bo)動(dong)(dong)(dong),否則, 會導致顯示的(de)(de)(de)較大波(bo)動(dong)(dong)(dong)。如果(guo)這時的(de)(de)(de)顯示波(bo)動(dong)(dong)(dong)幅度(du)不(bu)超過波(bo)動(dong)(dong)(dong)電(dian)壓的(de)(de)(de)波(bo)動(dong)(dong)(dong)幅度(du), 電(dian)好尺就屬于正常。
2、Gefran電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)尺供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)要有足夠的(de)(de)容量(liang),如果電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)容量(liang)太小(xiao),容易發生如下情(qing)況:合(he)模運動(dong)(dong)(dong)(dong)會導致射膠Gefran電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)尺顯示(shi)跳動(dong)(dong)(dong)(dong),或熔(rong)膠運動(dong)(dong)(dong)(dong)會導致合(he)模電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)尺的(de)(de)顯示(shi)波(bo)動(dong)(dong)(dong)(dong)。特別是電(dian)(dian)(dian)(dian)(dian)(dian)磁閥驅動(dong)(dong)(dong)(dong)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)于Gefran電(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)尺供電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)在一 起(qi)時(shi)(shi)容易出現(xian)上述情(qing)況,嚴(yan)重(zhong)時(shi)(shi)可以萬用表的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓檔測量(liang)到電(dian)(dian)(dian)(dian)(dian)(dian)壓的(de)(de)波(bo)動(dong)(dong)(dong)(dong)。如果在排除了靜電(dian)(dian)(dian)(dian)(dian)(dian)干擾、高頻干擾、對中性(xing)不好的(de)(de)情(qing)況下仍(reng)不能解決問題,也可以懷疑是電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)的(de)(de)功率偏(pian)小(xiao)。
3、Gefran電(dian)(dian)(dian)(dian)(dian)子尺(chi)不(bu)能有外界的干(gan)擾,包括靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)干(gan)擾和(he)高(gao)(gao)頻(pin)(pin)(pin)干(gan)擾。因(yin)此,設備的強電(dian)(dian)(dian)(dian)(dian)線(xian)(xian)(xian)路與(yu)電(dian)(dian)(dian)(dian)(dian)子尺(chi)的信(xin)號線(xian)(xian)(xian)應(ying)(ying)分開線(xian)(xian)(xian)槽(cao)。電(dian)(dian)(dian)(dian)(dian)尺(chi)應(ying)(ying)使用(yong)強制接(jie)地(di)(di)(di)支架,且(qie)(qie)使Gefran電(dian)(dian)(dian)(dian)(dian)子尺(chi)外殼(可(ke)測(ce)量(liang)(liang)端蓋(gai)螺絲(si)與(yu)支架之間的電(dian)(dian)(dian)(dian)(dian)阻,應(ying)(ying)小于10電(dian)(dian)(dian)(dian)(dian)阻)良好接(jie)地(di)(di)(di),信(xin)號線(xian)(xian)(xian)應(ying)(ying)使用(yong)屏蔽線(xian)(xian)(xian),且(qie)(qie)在電(dian)(dian)(dian)(dian)(dian)箱的一端應(ying)(ying)予將(jiang)屏蔽線(xian)(xian)(xian)接(jie)地(di)(di)(di)或(huo)接(jie)直流電(dian)(dian)(dian)(dian)(dian)源負(fu)極。靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)干(gan)擾時(shi), -般萬用(yong)表的電(dian)(dian)(dian)(dian)(dian)壓測(ce)量(liang)(liang)非常(chang)正(zheng)常(chang),但就(jiu)是顯(xian)示數字跳(tiao)動;高(gao)(gao)頻(pin)(pin)(pin)干(gan)擾時(shi)其現象(xiang)也一樣。驗(yan)證是不(bu)是靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)干(gan)擾,用(yong)一段電(dian)(dian)(dian)(dian)(dian)源線(xian)(xian)(xian)將(jiang)杰佛倫(lun)電(dian)(dian)(dian)(dian)(dian)阻尺(chi)的封蓋(gai)螺絲(si)與(yu)機(ji)器(qi)上某一點輇屬(shu)短(duan)接(jie)即可(ke),只要一短(duan)接(jie),靜(jing)(jing)電(dian)(dian)(dian)(dian)(dian)干(gan)擾立即消除。但高(gao)(gao)頻(pin)(pin)(pin)干(gan)擾就(jiu)難以用(yong)上述辦法(fa)(fa)消除,而且(qie)(qie)機(ji)器(qi)手、變(bian)頻(pin)(pin)(pin)節(jie)電(dian)(dian)(dian)(dian)(dian)器(qi)多出現高(gao)(gao)頻(pin)(pin)(pin)干(gan)擾,可(ke)以用(yong)停止(zhi)機(ji)器(qi)手或(huo)變(bian)頻(pin)(pin)(pin)節(jie)電(dian)(dian)(dian)(dian)(dian)器(qi)的辦法(fa)(fa)驗(yan)證。
4、不能接錯Gefran電子尺的三條線(xian)(xian)(xian), 1#、3#線(xian)(xian)(xian)是(shi)電源線(xian)(xian)(xian), 2#是(shi)輸出線(xian)(xian)(xian)除(chu)1#、3#線(xian)(xian)(xian)電源線(xian)(xian)(xian)可以調換外, 2#線(xian)(xian)(xian)只能是(shi)輸出線(xian)(xian)(xian)。 上(shang)述(shu)線(xian)(xian)(xian)- 旦接錯,將(jiang)出現(xian)(xian)線(xian)(xian)(xian)性誤差大(da),控制精度差,容易顯示跳動等現(xian)(xian)象(xiang)。如果出現(xian)(xian)控制非常困難(nan),就應該懷(huai)疑是(shi)接錯線(xian)(xian)(xian)。
5、Gefran電子尺(chi)(chi)安裝對中性要好,角度(du)(du)(du)容許(xu)+12°誤差(cha),平行(xing)度(du)(du)(du)偏(pian)差(cha)容許(xu)+0.5mm ,是指某(mou)- -誤差(cha),如(ru)果角度(du)(du)(du)誤差(cha)和(he)平行(xing)度(du)(du)(du)誤差(cha)都(dou)偏(pian)大,就會導致顯(xian)示數(shu)字跳動。在這(zhe)種情況下,一般可以用萬用表的(de)電壓檔測出電壓的(de)波動。 -定要作(zuo)角度(du)(du)(du)和(he)平行(xing)度(du)(du)(du)的(de)調整(zheng)。請(qing)特別注意:在現場將(jiang)杰佛倫(lun)電阻(zu)尺(chi)(chi)的(de)鋁(lv)合金支架更(geng)換成不(bu)銹鋼支架后,同時應將(jiang)拉桿(gan)牽引安裝位升高(gao)2 mm。否則,接地問題解決了(le),又形(xing)成了(le)不(bu)對中的(de)問題,必須同時解決。杰佛倫(lun)Gefran電子尺(chi)(chi)現貨
6、對于使用時間(jian)很久的(de)(de)(de)Gefran電(dian)子尺,由于前(qian)期(qi)產品(pin)無密封,可能有很多雜(za)質,并有油(you)、水混合物,影響電(dian)刷的(de)(de)(de)接觸電(dian)阻(zu),導致顯示數(shu)字跳動,可以(yi)認為電(dian)子尺本身(shen)的(de)(de)(de)早(zao)期(qi)損壞。
7、Gefran電(dian)子尺顯示故(gu)障的(de)處理簡單。設(she)備: 上只要一只數字式萬(wan)用表,一段電(dian)線即可(ke),只要綜合分(fen)析,判斷問題(ti)和解決(jue)問題(ti)不是困(kun)難。杰佛倫Gefran電(dian)子尺現貨
Gefran電子尺安裝(zhuang)注意事項(xiang)
一、選擇(ze)Gefran電(dian)子尺規(gui)(gui)格(ge)(ge)需留有余量，- 般(ban)在實際行(xing)程的基礎(chu)上(shang)選大-規(gui)(gui)格(ge)(ge)的即可。
二、同時注意, 1000mm規格以下可(ke)選(xuan)用KTC拉桿系列,大于此行程的(de)規格，或不(bu)便于進行對中調整(zheng)的(de)場合(he), 宜選(xuan)用KTF滑(hua)塊結構(gou)。
三(san)、Gefran電子(zi)尺(chi)的(de)安(an)裝(zhuang)宜將余量均(jun)勻(yun)留(liu)在兩端(duan),未確定極限位置之前不要鎖緊(jin)固(gu)定支架螺絲(si),待調整行(xing)程OK后才能鎖緊(jin)Gefran電子(zi)尺(chi)固(gu)定支架螺絲(si)
四、拉桿式Gefran電(dian)子尺的(de)(de)拉球萬向頭允許半徑1mm的(de)(de)對(dui)中性偏差(cha),當(dang)然規格越(yue)短,建議(yi)對(dui)中偏差(cha)越(yue)小(xiao)。
五、固定杰佛倫電阻(zu)尺后,將拉桿( KTC、KTM系列均適用)縮(suo)回(hui)時,向球頭的(de)圓主本(ben)體應能在四個徑向方位有空隙。否(fou)則,調(diao)整萬向頭安裝位或(huo)調(diao)整靠近伸出端的(de)安裝支架位。
六在(zai)拉桿拉出時如有很(hen)大的不(bu)對中(zhong),應(ying)調整靠近(jin)插頭那(nei)端的安(an)裝支架。這(zhe)可作為一種輔助復查方式。
七、拉球萬(wan)向頭安裝桿與拉桿允許角(jiao)度t 12o的傾(qing)斜。但如果(guo)安裝時(shi)對中偏差和傾(qing)斜偏差同(tong)時(shi)都很大將會(hui)影響Gefran電子(zi)尺的穩定性和使用壽命。應予(yu)以進(jin)一步(bu)調整。
八(ba)、滑塊杰佛倫(lun)電阻尺(chi)(chi)可以(yi)減少調整對(dui)中性的工作量,但輔助加長桿不能取消,否則(ze),會出現由于對(dui)中性不好而導(dao)致穩(wen)定性和使(shi)用壽命,甚至當即致使(shi)杰佛倫(lun)電阻尺(chi)(chi)失(shi)效。
九、一切(qie)調整好后,緊固安裝螺絲(si),力度(du)應使接地電(dian)(dian)阻小于(yu)1Q為宜。肪用表200Q檔位測量(liang)杰佛倫(lun)電(dian)(dian)阻尺封蓋螺絲(si)與安裝裝架(jia)之間的電(dian)(dian)阻。
十、 使用(yong)四線(xian)制(zhi)或(huo)帶有(you)屏蔽線(xian)的配線(xian),杰佛(fo)倫電(dian)阻尺那(nei)端接(jie)(jie)地端應連接(jie)(jie),同(tong)時(shi)將第(di)四端或(huo)屏蔽線(xian)在(zai)電(dian)控(kong)箱端可靠接(jie)(jie)地。
