Abstract: Edw ards ro tary vacuum pump is a two stage, o il sealed ro tary vane pump
operating acco rding to the ro tary vane p rinciple. In th is paper, the w o rk ing theo ry of
Edw ards ro tary vacuum pump w as described. O n the base of p ractical u se and m ain tain ing,
the con ten ts requ ired to check fo r m ain tenance daily w ere summ arized. How to judge their
fam iliar troub le and how to reso lve them are described. F inally how to imp rove and at
w here to imp rove fo r the vacuum pump w ere discu ssed in greater detail.
