JZJWLW系列真空機組，是以羅茨真空泵為主泵， 立式無油往復真空泵為前級泵， 通過電接點真空表來實現羅茨真空泵， 立式無油往復真空泵自動啟停， 自動保護哀空系統的真空獲得設備。廣泛應用于電子、真空踱膜、 化纖 、冶金、熱處理、焊接、化工等行業。

它除了具有一般羅茨真空泵機組的特點外 ，由于采用無油立式往塵真空泵作為前級泵， 還能提高真空清潔度， 特別適合抽除遇油反應的氣體和無壓縮凝固性的氣體。

JZJWLW series vacuum unit is based on Roots vacuum pump as the main pump. The vertical oil-free reciprocating vacuum pump is the front stage pump. The Roots vacuum pump 1s reauzed by the electric contact vacuum table. The vertical 0il- free rec1procating vacuum pump automatically starts and stops, and the automatic protection vacuum  system  The  vacu  um  gets the  equipment Widely used 1n electronics, vacuum coating, chemical fiber. metallurgy,heat treatment, welding, chemical and other industries.

In addition to the characteristics of the general Roots vacuum pump unit, it also improves the vacuum cleanliness by using the 0il- free vertical reciprocat  ing vacuum pump as the foreline pump. It 1s especially suitab le for removing oils and non-compressed coagulating gases.
