YAW-3000A微(wei)機(ji)控(kong)制電(dian)液(ye)伺(si)服壓力試(shi)驗(yan)機(ji)

主(zhu)要用(yong)於多(duo)種材(cai)料的壓(ya)縮試(shi)驗(yan)，例(li)如(ru)：水(shui)泥、混(hun)凝土、各種建(jian)築(zhu)用(yong)磚(zhuan)、橡膠(jiao)墊(dian)、混凝土構件(jian)、金(jin)屬(shu)構(gou)件(jian)等(deng)的(de)抗(kang)壓(ya)強度(du)試(shi)驗(yan)。

主(zhu)要由主(zhu)機、伺(si)服(fu)油(you)源、電(dian)控(kong)櫃(gui)及計(ji)算機(ji)打印(yin)件(jian)等(deng)部分組成。采用(yong)液(ye)壓加荷、油(you)壓(ya)傳(chuan)感器(qi)測(ce)力、PC機(ji)-電(dian)液(ye)伺(si)服控制(zhi)系統(tong)自(zi)動(dong)控制(zhi)試(shi)驗(yan)進(jin)程，微(wei)機屏幕顯(xian)示試(shi)驗(yan)數(shu)據及曲線(xian)，可進(jin)行(xing)數(shu)據處(chu)理、儲(chu)存及打(da)印(yin)。

  為雙(shuang)絲杠框架結(jie)構、移(yi)動(dong)式橫(heng)梁(liang)、油(you)缸下置(zhi)式(shi)主機。移(yi)動(dong)式橫(heng)梁(liang)可在壹(yi)定(ding)範(fan)圍內任意調整試(shi)驗(yan)空(kong)間(jian)。主(zhu)機(ji)部分主(zhu)要由橫(heng)梁(liang)、絲杠、工(gong)作(zuo)臺、小車等(deng)部分組成。橫(heng)梁(liang)由二(er)絲杠支(zhi)撐(cheng)在底(di)座(zuo)上，由螺(luo)帽加以(yi)緊(jin)固(gu)構(gou)成(cheng)加荷框架；橫(heng)梁(liang)上裝有球面(mian)座(zuo)，上壓(ya)盤裝在球面(mian)座(zuo)上，加荷時可根據(ju)試(shi)件(jian)形(xing)狀自(zi)動(dong)調整方向(xiang)，使(shi)試(shi)件(jian)受(shou)力均(jun)勻；橫(heng)梁(liang)上裝有調整電(dian)機(ji)，由電(dian)機(ji)帶(dai)動(dong)蝸桿(gan)，蝸(wo)桿(gan)帶動(dong)蝸輪(lun)，再由蝸(wo)輪帶(dai)動(dong)絲母旋轉，絲母帶動(dong)橫(heng)梁(liang)上下(xia)移動(dong)，從而調整試(shi)驗(yan)空(kong)間(jian)；橫(heng)梁(liang)中裝有彈簧，支撐(cheng)起橫(heng)梁(liang)的重(zhong)量(liang)，消除掉絲母螺紋(wen)與絲杠螺(luo)紋(wen)豎(shu)直(zhi)方向(xiang)上的間(jian)隙，使(shi)試(shi)驗(yan)可靠，數(shu)據準(zhun)確；下壓(ya)盤裝在小(xiao)車上(shang)，小(xiao)車(che)可在軌(gui)道(dao)上來(lai)回移(yi)動(dong)，裝卸試(shi)件(jian)均(jun)可拉(la)出小(xiao)車。下壓盤的圓(yuan)刻(ke)線是為了(le)便於放(fang)置(zhi)試(shi)樣。主(zhu)機(ji)上(shang)的油(you)管與油(you)源相(xiang)通(tong)。當控制油(you)液(ye)進(jin)入(ru)油(you)缸後，推(tui)動(dong)活塞(sai)連同(tong)固(gu)定(ding)工(gong)作臺及下(xia)壓(ya)盤(pan)上升，使(shi)試(shi)驗(yan)力逐(zhu)漸(jian)作(zuo)用(yong)在(zai)試(shi)樣上(shang)。
