JZJLG系列真(zhen)(zhen)(zhen)空(kong)(kong)機(ji)組(zu)，是以羅(luo)茨真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)為(wei)主泵(beng)，螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)為(wei)前(qian)級(ji)泵(beng)，漁過電接(jie)點(dian)真(zhen)(zhen)(zhen)空(kong)(kong)表來實現羅(luo)茨真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)，螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)自(zi)動啟停(ting)，自(zi)動保(bao)護(hu)真(zhen)(zhen)(zhen)空(kong)(kong)系統(tong)的(de)(de)真(zhen)(zhen)(zhen)空(kong)(kong)獲得(de)設備。廣泛應(ying)用于電子行業(ye)。它除了具有般羅(luo)茨真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)機(ji)組(zu)的(de)(de)特點(dian)外， 由于采用螺(luo)桿真(zhen)(zhen)(zhen)空(kong)(kong)泵(beng)作為(wei)前(qian)級(ji)泵(beng)，不僅真(zhen)(zhen)(zhen)空(kong)(kong)度(du)離，還(huan)能(neng)提離真(zhen)(zhen)(zhen)空(kong)(kong)清潔度(du)，特別適合抽除遇油反(fan)應(ying)的(de)(de)氣(qi)體(ti)和無(wu)(wu)壓(ya)縮凝固性的(de)(de)氣(qi)體(ti)。 是目前(qian)取代立式(shi)無(wu)(wu)油真(zhen)(zhen)(zhen)空(kong)(kong)機(ji)組(zu)的(de)(de)最佳選擇。

JZJLG series vacuum unit 1s based on Roots vacuum pump as the main pump. The Screw vacuum pump 1s the front stage pump. The Roots vacuum pump is realized by the electric contact vacuum table. The Screw vacuum pump automatically starts and stops, and 

the automatic protection vacuum system The vacuum gets the equipment. Widely used 1n electronics, vacuum coating, chemical fiber metallurgy, heat treatment, welding, chemical and otherindustries

In addition to the characterist1cs of the general Roots vacuum pump unit, 1t also improves the vacuum cleanliness by using the Screw vacuum pump as the foreline pump. It is especially suitable foremoving oils and non-compressed coagulating gases
