羅(luo)(luo)茨真空泵(beng)(beng)(beng)(beng)(beng)(beng)是一種雙轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)(de)容積式(shi)(shi)(shi)真空泵(beng)(beng)(beng)(beng)(beng)(beng)。在泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)內(nei)有(you)(you)兩個形狀對稱的(de)(de)(de)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi),轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)形狀有(you)(you)兩葉、三葉和(he)四(si)葉的(de)(de)(de)。兩個轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)彼(bi)此(ci)朝相反方向旋(xuan)轉(zhuan)(zhuan)(zhuan),由(you)(you)軸端齒(chi)輪(lun)驅動(dong)同步轉(zhuan)(zhuan)(zhuan)動(dong)。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)彼(bi)此(ci)無接觸,轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)與(yu)泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)壁也無接觸,其間(jian)通(tong)常有(you)(you)0.15~1.0mm的(de)(de)(de)間(jian)隙(xi),泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)靠間(jian)隙(xi)來密(mi)封(feng)。 由(you)(you)于羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)內(nei)無摩擦,轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)可(ke)高(gao)速(su)運(yun)轉(zhuan)(zhuan)(zhuan),一般為(wei)1500~3000r/min,而(er)且不必用(yong)潤滑(hua)油(you),可(ke)實現無油(you)清(qing)潔的(de)(de)(de)抽氣過(guo)(guo)程。泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)潤滑(hua)部位(wei)僅(jin)限于軸承(cheng)和(he)齒(chi)輪(lun),以及動(dong)密(mi)封(feng)處。泵(beng)(beng)(beng)(beng)(beng)(beng)沒有(you)(you)往復運(yun)動(dong)部件,故可(ke)實現良好的(de)(de)(de)動(dong)平衡。因而(er),羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)運(yun)轉(zhuan)(zhuan)(zhuan)平穩(wen),轉(zhuan)(zhuan)(zhuan)速(su)高(gao),尺(chi)寸小可(ke)獲得(de)大的(de)(de)(de)抽速(su)。 目前國內(nei)外(wai)的(de)(de)(de)羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng),多(duo)數為(wei)臥式(shi)(shi)(shi)結(jie)(jie)構(gou),泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)進(jin)氣口(kou)在上,排氣口(kou)在下,這種臥式(shi)(shi)(shi)結(jie)(jie)構(gou)重心低,高(gao)速(su)運(yun)轉(zhuan)(zhuan)(zhuan)時(shi)穩(wen)定性好。羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)兩個轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)是通(tong)過(guo)(guo)一對高(gao)精度(du)的(de)(de)(de)齒(chi)輪(lun)來實現其相對同步旋(xuan)轉(zhuan)(zhuan)(zhuan)的(de)(de)(de)。 泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)傳(chuan)(chuan)動(dong)多(duo)為(wei)直聯式(shi)(shi)(shi)的(de)(de)(de),大泵(beng)(beng)(beng)(beng)(beng)(beng)則有(you)(you)皮帶傳(chuan)(chuan)動(dong)的(de)(de)(de)。電動(dong)機與(yu)傳(chuan)(chuan)動(dong)齒(chi)輪(lun),多(duo)設(she)在轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)軸的(de)(de)(de)兩側,安裝(zhuang)拆卸方便。主動(dong)軸傳(chuan)(chuan)遞的(de)(de)(de)扭矩較大,軸要(yao)(yao)有(you)(you)足夠的(de)(de)(de)強度(du)和(he)剛度(du),軸與(yu)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)要(yao)(yao)固結(jie)(jie)牢靠。羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)密(mi)封(feng)很關鍵,主動(dong)軸外(wai)伸(shen)部分、兩個轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)的(de)(de)(de)軸承(cheng)與(yu)泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)之間(jian)設(she)有(you)(you)動(dong)密(mi)封(feng),泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)與(yu)各(ge)端蓋設(she)有(you)(you)靜密(mi)封(feng)。 為(wei)了避免羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)誤操作(zuo),一般多(duo)設(she)有(you)(you)旁路溢流閥。根據對羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)特殊需要(yao)(yao),也有(you)(you)將油(you)的(de)(de)(de)齒(chi)輪(lun)箱,軸承(cheng)等部件與(yu)泵(beng)(beng)(beng)(beng)(beng)(beng)腔(qiang)做(zuo)成分離式(shi)(shi)(shi)結(jie)(jie)構(gou)的(de)(de)(de)。 在羅(luo)(luo)茨泵(beng)(beng)(beng)(beng)(beng)(beng)的(de)(de)(de)壓(ya)縮過(guo)(guo)程中產生的(de)(de)(de)熱量(liang)被傳(chuan)(chuan)到轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)和(he)泵(beng)(beng)(beng)(beng)(beng)(beng)體(ti)(ti)上。轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)很難將熱量(liang)傳(chuan)(chuan)至泵(beng)(beng)(beng)(beng)(beng)(beng)外(wai),而(er)泵(beng)(beng)(beng)(beng)(beng)(beng)體(ti)(ti)的(de)(de)(de)熱量(liang)很容易被散(san)失到周(zhou)圍大氣中。因而(er)轉(zhuan)(zhuan)(zhuan)子(zi)(zi)(zi)與(yu)泵(beng)(beng)(beng)(beng)(beng)(beng)體(ti)(ti)之間(jian)就出...
