人(ren)類太空探索(suo)的(de)(de)(de)步伐正在加快，對空間(jian)技術(shu)提出了更(geng)高的(de)(de)(de)要(yao)求。空間(jian)環(huan)境模(mo)擬器(qi)是確保航(hang)天器(qi)在發射，運(yun)行和返回過程(cheng)中安(an)全運(yun)行的(de)(de)(de)主要(yao)設備。真(zhen)空環(huan)境是地面上的(de)(de)(de)空間(jian)環(huan)境模(mo)擬器(qi)。模(mo)擬的(de)(de)(de)一(yi)個重(zhong)要(yao)部(bu)分(fen)。
真(zhen)空(kong)(kong)(kong)(kong)技(ji)術和航空(kong)(kong)(kong)(kong)航天(tian)(tian)技(ji)術之間(jian)的(de)(de)(de)主要(yao)聯系(xi)來(lai)自空(kong)(kong)(kong)(kong)間(jian)的(de)(de)(de)環(huan)境模(mo)(mo)擬，因為諸如運載(zai)火箭(jian)，衛星，載(zai)人(ren)航天(tian)(tian)器，空(kong)(kong)(kong)(kong)間(jian)站(zhan)，太空(kong)(kong)(kong)(kong)探測(ce)器和航天(tian)(tian)飛(fei)(fei)機等各(ge)種(zhong)(zhong)(zhong)太空(kong)(kong)(kong)(kong)飛(fei)(fei)行器正在(zai)進(jin)行太空(kong)(kong)(kong)(kong)飛(fei)(fei)行。它是在(zai)宇宙(zhou)的(de)(de)(de)自然(ran)真(zhen)空(kong)(kong)(kong)(kong)中進(jin)行的(de)(de)(de)。因此，除了受(shou)到空(kong)(kong)(kong)(kong)間(jian)真(zhen)空(kong)(kong)(kong)(kong)環(huan)境的(de)(de)(de)直接影響外，它們(men)還(huan)受(shou)到太陽輻射(she)，各(ge)種(zhong)(zhong)(zhong)帶電粒子和溫度的(de)(de)(de)影響。這些(xie)因素會(hui)導致材料特性的(de)(de)(de)變(bian)化或損壞(huai);儀器靈敏度的(de)(de)(de)失效將破壞(huai)這些(xie)飛(fei)(fei)機的(de)(de)(de)工(gong)作，甚(shen)至造成宇航員(yuan)的(de)(de)(de)傷亡。為此，有(you)必要(yao)建(jian)立一個模(mo)(mo)擬地(di)面空(kong)(kong)(kong)(kong)間(jian)環(huan)境的(de)(de)(de)空(kong)(kong)(kong)(kong)間(jian)模(mo)(mo)擬實驗裝置(zhi)。因為在(zai)各(ge)種(zhong)(zhong)(zhong)飛(fei)(fei)機之前只有(you)通過地(di)面的(de)(de)(de)模(mo)(mo)擬實驗。掌握航天(tian)(tian)器在(zai)太空(kong)(kong)(kong)(kong)工(gong)作的(de)(de)(de)條件和特點，消(xiao)除飛(fei)(fei)行中的(de)(de)(de)各(ge)種(zhong)(zhong)(zhong)隱患，可以保證飛(fei)(fei)機和宇航員(yuan)的(de)(de)(de)安全。為了滿(man)足這些(xie)要(yao)求，目前在(zai)地(di)面上建(jian)立了各(ge)種(zhong)(zhong)(zhong)模(mo)(mo)擬裝置(zhi)。
螺桿真(zhen)空(kong)泵具有清潔無油，抽速大，振動小，噪音低等優點，已成為大型空間模擬真空系統的首選。另外，為了提高真空機組的抽速和極限真空度，減小螺桿泵的尺寸，一般采用由羅茨真空泵和螺桿真空泵組成的兩級機組。真空泵。一個三級單元，由兩個羅茨泵與一個螺桿真空泵串聯組成。為防止顆粒雜質進入泵，入口過濾器放置在真空裝置的入口處，精度為50μm。
關于螺桿真(zhen)空泵在航(hang)空航(hang)天工業(ye)(ye)中的(de)(de)應(ying)用(yong)，需(xu)要更(geng)長時間才能更(geng)深(shen)入(ru)地學習。由(you)于隨著(zhu)時間的(de)(de)推移(yi)真(zhen)空技術的(de)(de)變化和(he)研究人員的(de)(de)研究工作(zuo)，我相信在不久(jiu)的(de)(de)將來，真(zhen)空泵可(ke)以應(ying)用(yong)于目前無法應(ying)用(yong)的(de)(de)地方，我們始(shi)終堅持我國的(de)(de)專業(ye)(ye)技術并可(ke)以引領真(zhen)空泵行業(ye)(ye)走(zou)向更(geng)高(gao)的(de)(de)位置。
