DRY VACUUM PUMP UNIT AND METHOD FOR STARTING THE SAME, AND AIR-COOLED DRY VACUUM PUMP

摘要

Disclosed is a dry vacuum pump unit which is small and lightweight so as to be movable to a required place by hand, and which can cool electric components or pumps by efficiently releasing heat generated from the components or the pumps.  The dry vacuum pump unit is comprised of a booster pump (4) disposed on the vacuum side, a main pump (5) disposed on the atmospheric pressure side, and a radiator plate (2) provided with cooling fins (11).  An electric component (3) is mounted on the radiator plate (2).  The booster pump (4) and the main pump (5) are attached to the radiator plate (2) via a pump mounting pedestal (14) comprised of a material having excellent thermal conductivity, or are directly attached to the radiator plate (2).
