To achieve these goals, this utility model adopts the following technical scheme that a kind of vacuum pump sound insulation lid, sound insulation lid is consolidated
It is scheduled on vacuum pump frame, sound insulation lid is the tubular lid that one end open is closed in one end, between sound insulation lid and vacuum pump frame successively
Noise reduction set, aerofluxuss disk, stator, suction disk, sealing ring are provided with, described sound insulation lid blind end inner side is provided with the first ring of concentric
Shape boss, the second annular boss, described noise reduction set respectively with first annular boss top surface, the second annular boss top surface, sound insulation
Lid medial surface, aerofluxuss side surface are close to, and described first annular boss, sound insulation lid blind end medial surface and noise reduction cover to form first
Surge chamber, described the second annular boss, sound insulation lid blind end medial surface and noise reduction cover to form the second surge chamber, and described second
Annular boss, sound insulation lid blind end medial surface, sound insulation lid medial surface and noise reduction set form discharge chamber, on the first annular boss
Two vent grooves are provided with, second annular boss is provided with multiple ventilation shrinkage pools.In this programme, sound insulation is covered whole electronic
The effect of gas transfer is undertaken in vacuum pump, pedestal is that at the air inlet and aerofluxuss of electric vacuum pump, gas enters from pedestal air inlet
Enter and be transported to by suction disk, stator, aerofluxuss armor into electric vacuum pump working chamber in, be then discharged in working chamber
And the surge chamber of sound insulation lid first buffering is covered into by aerofluxuss disk and noise reduction, then delayed into the second surge chamber by vent grooves
Punching, then discharge chamber is entered by ventilation shrinkage pool, discharge chamber is connected with pedestal air vent, and gas is discharged from air vent, realizes gas
One-way movement, so, in the carrier connected with air-inlet of vacuum pump（Vehicle）Position can form vacuum.
Preferably, it is in that Radiation is equal that the first described buffering interior is provided with 8 with the sound insulation lid blind end center of circle as the center of circle
The radiation item of even arrangement.First surge chamber is separated into 8 minibuffer chambers by 8 radiation items of this programme, and gas is slow into first
Rush behind room through the buffering in 8 minibuffer chambers, noise of the gas quickly produced by flowing can be greatly reduced, reduce whole vacuum
Noise during pump work.
Preferably, described sound insulation cover gab end is provided with the flange for stretching out, described flange is provided with fixing hole.
Sound insulation cover gab end is adjacent to and is fixed with end face by sealing ring and vacuum pump frame, with bolts, will by fixing hole
Sound insulation lid is fixed on vacuum pump frame, can be fixedly secured and keep sealing.
Preferably, described sound insulation lid medial surface is provided with multiple noise reduction posts.Gas passes through when aerofluxuss intracavity flows
Be arranged on noise reduction post on sound insulation lid medial surface can mitigation of gases speed, reduce noise, noise reduction post from sound insulation cover gab end face to
Sound insulation lid blind end medial surface straight-line extension.
The beneficial effect of this programme is：1) impact load and noise in pump housing operation process is alleviated；2) this programme body
Product is little, installs and safeguards more easy.
