We can see that underneath the Roots blower is a base, the base structure is simple, but the learning in it is not simple. For example, the handling of the centerline deviation of the foundation of Roots blower, when the deviation is large, it can be remedied by changing the position of the ground bolt. Roots blower in the installation of the foundation surface before shoveling out some small pits (except for the place to put the pad iron), known as shoveling hemp surface. This can make the secondary grouting is poured concrete or cement mortar can be tightly integrated with the foundation. Shoveling method has hand method and wind shovel method, generally require each 100c ㎡ within 5 ~ 6 diameter of 10 ~ 20mm small pit. In order to facilitate the adjustment of the level and height of the fuselage, Roots blower is generally placed on the foundation and make the weight of the pad iron through the pad iron evenly transferred to the foundation. Roots blower if the base is not fixed, it will lead to poor operation of the Roots blower, and in serious cases make the Roots blower collapse, causing an unnecessary series of accidents.
