It is also preferred that the left the inside of described point of lid is provided with cavity, described adjacent between cavity seal against each other connection.
By use technique scheme, cavity be connected with each other the annular seal space that coordinates, it is simple to cooling wind flowing.
It is also preferred that the left the outside of described pump case is provided with several fin, between described fin, leave gap.
By using technique scheme, fin adds pump case and extraneous contact area so that pump case cooling is the rapidest.
It is also preferred that the left described fin is circular and is surrounded on the outer wall of described pump case.
By using technique scheme, it is looped around the outer wall of pump case so that fin is more uniform to the heat radiation of the pump housing, improves the uneven situation causing pump case flatulence of heat type uneven and to be split up of pump case heat radiation.
It is also preferred that the left one end of described pump case is fixed with electric rotating machine, described pump case is fixed on frame, and described frame is provided with the push rod supporting electric rotating machine.
By using technique scheme, electric rotating machine drives the rotor in pump case, and electric rotating machine will occur slight shake when unsettled rotation, electric rotating machine when shake by frictional heat.Therefore by push rod, electric rotating machine is fixed, improve the jitter conditions of electric rotating machine, decrease the transmission to pump case of the electric rotating machine heat energy, to pump case Pneumatic cooling effect.
It is also preferred that the left described push rod is threadedly connected to described frame, described push rod rotates in a circumferential direction and drives own axes conflict electric rotating machine.
By using technique scheme, push rod passes through screw thread turn so that push rod can be without number of poles to electric rotating machine jack-up so that push rod can be crossed and support electric rotating machine in position the most accurately, further reduces the shake of its rotating motor.
It is also preferred that the left described push rod is provided with the outer-hexagonal rotating part for rotating in a circumferential direction.
By using technique scheme, outer-hexagonal rotating part is easy to screwing of employee.
In sum, this utility model has the advantages that the annular seal space by opening ventilating air in pump case, through the blower fan traction to wind, it is achieved quick-replaceable cooling wind in annular seal space, plays pump case fast cooling effect.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
Embodiment 1, (air-cooled vacuum pump), as it is shown in figure 1, frame 8 includes the passive metallic rod in bottom, the top of metallic rod is welded with the metallic plate placing vacuum pump.The pump case 1 of vacuum pump is by being fixed by screws in the top of metallic plate.
Pump case 1 is from left to right divided into five points of lids 11, high order end divides lid 11 to fix electric rotating machine 7 by screw, five points of lids 11 are circular, and point lid 11 of low order end is integrally formed with shrouding, point lid 11 of low order end plays the effect of seal cage 1, being connected by screw fixing between adjacent point of lid 11, screw is arranged in point outer circumferential walls of lid 11 uniformly.And left and right docking windshield bearing surface each other is burnishing surface, divides the joint face between lid 11 to fit each other after screw is fixing and form annular seal space 2 Room.This annular seal space 2 Room rotarily drives fluid motion for blade.
Middle point lid 11 castings have fin 6, the quantity of fin 6 to be seven and be circular, and fin 6 is arranged in the outer circumferential walls of middle point of lid 11.Owing to the spacing between abutting fins 6 is identical so that the heat radiation of middle point of lid 11 is more uniform.
(annular seal space 2), as in figure 2 it is shown, offer circular cavity 21 on each point of lid 11, cavity 21 is circular, communicating with each other between adjacent cavity 21 and form the annular seal space 2 of air current flow, whole pump case 1 is covered by ring-type due to cavity 21 so that the air-flow in the cavity 21 of pump case 1 is uniform.
As it is shown on figure 3, be fixed with blower fan 5 by screw at import 3 below point lid 11 of high order end, import 3 connects with cavity 21 and is used for into cooler.This blower fan 5 is power frequency centrifugal blower 5, and power frequency centrifugal blower 5 has good draw to gas, improves air-cooled efficiency.In Fig. 2, and having blower fan 5 by screw on point lid 11 of low order end, blower fan 5 connects with outlet 4, and outlet 4 connects with cavity 21, and this extension set is also power frequency centrifugal blower 5.Import 3 and outlet 4 all with pump case ft connection.
When both sides blower fan 5 does not starts, the blade face of blower fan 5 self, place foreign body and enter in annular seal space 2.And import 3 blower fan 5, air inlet；Export 4 blower fans 5, give vent to anger so that cool down gas has bigger pull strength in annular seal space 2, and the flowing of cooling wind is more smooth.
Embodiment 2, (air-cooled vacuum pump) as best shown in figs. 1 and 4, it is with the difference of embodiment, and electric rotating machine 7 fixes the left side of pump case 1 by screw, and conflicting in the lower section of electric rotating machine 7 has push rod 9.Push rod 9 is outer-hexagonal bolts, and the upper end of push rod 9 is outer-hexagonal rotating part 91, quickly screwing for spanner, and the lower end of push rod 9 is connected through frame 8 and with the nut thread in frame 8, and this nut weld is in frame 8.By outer-hexagonal rotating part 91 so that push rod 9 moves up and realize the shell of conflict electric rotating machine 7, improve the shake of electric rotating machine 7.
