Description

Oil-free vacuum pump fixing support

Technical Field

The utility model relates to a technical field of fixed bolster, in particular to there is not oily vacuum pump fixed bolster.

Background

The electronic vacuum pump is a device which adopts a piezoelectric material as a power device (a motor driving mode is completely abandoned), electronization is thoroughly realized from control to driving, and an electronic integrated system completely controls the exchange and transmission of gas, so that the adjustability and the accuracy of gas transmission are realized.
