Cavity is closed, the open end of semiclosed cavity is arranged in first side.
Second aspect, a kind of Roots vaccum pump, including wallboard, wallboard are arranged between fuel tank and vacuum pump ontology.
The utility model has the advantages that the Roots vaccum pump wallboard with heat insulating function of the utility model, by being set in wallboard body
Semi-enclosed cavity is set, the open end of semiclosed cavity is arranged in side of the wallboard body towards vacuum pump ontology, utilizes vacuum
Cavity semiclosed in wallboard is pumped to vacuum state by the self-priming performance of pump, and the heat that barrier gas compression generates is to wallboard direction
Transfer, on the basis of not changing wallboard big structure and function, wallboard has been also equipped with heat-insulated function, additional without increasing
Radiator, tank temperature can be reduced, improve the lubricating condition of bearing, improve the reliability of vacuum pump and using the longevity
Life.
