Base hood is on fan air intake duct, and two blocks of side plates of silencing case base block the both ends open of fan air intake duct, fan air intake
Two blocks of side plates of groove also block the both ends open of silencing case base；
Pump frame is fixed on the top board of silencing case base, and vacuum pump is fixed on silencing case base by pump frame, and
Pump frame, just to fan location hole, is lined with rubber blanket to play damping, buffering effect between the top board of pump frame and silencing case base；
Sound insulation groove and outer housing are all the flute profile that Open Side Down, and the height of outer housing side plate is more than the height of sound insulation groove side plate, every
Sound groove is fixed on silencing case base and sound insulation groove covers on vacuum pump, and outer housing covers on sound insulation groove, the bottom of outer housing side plate and
The bottom of sound insulation groove side plate flushes, every block of side plate one block of side plate just to sound insulation groove respectively of outer housing, and the top of outer housing side plate is
Locate all to have exhaust vent above sound insulation grooved top plate, at the opening at outer housing two ends, respectively paste one piece of outer housing cover plate, outer housing every
Block side plate and just to sound insulation groove one block of side plate between be all lined with sound-absorbing pad, at the opening of every piece of outer housing cover plate and outer housing it
Between be also lined with sound-absorbing pad.
The described silencing case for vacuum pump, is characterized in that：Sound-absorbing pad is made with the loose porous shape material such as sponge, inhales
The thickness of sound pad is not less than 15mm, and the density of sound-absorbing pad is not more than 50kg/m3.
When this utility model uses, fan is fixed in fan air intake duct by fan Fixture, the blowing direction of fan
Just to the fan location hole in the middle part of silencing case base deck, vacuum pump is fixed on silencing case base by pump frame and makes sound insulation
Groove covers on vacuum pump；When vacuum pump operation, sound insulation groove and sound-absorbing pad absorb the overwhelming majority sending during vacuum pump operation
Noise, the rubber blanket between pump frame and silencing case base also functions to the effect that damping, buffering reduces noise；When fan runs, cold
Air enters fan air intake duct through air vent under the suction of fan, then flows through silencing case base and pump frame successively, and vacuum
There is heat exchange so that vacuum is pumped up with cooling effect in pump, subsequently discharge from the exhaust vent of outer housing through sound insulation groove again.
This utility model passes through loose porous sound-absorbing pad, resilient rubber blanket absorbs most noises, and basis
The traffic direction of vacuum pump devises gas circuit, so that cold air is entered from bottom, then goes up to the middle part of silencing case base, more horizontal
To through vacuum pump, making cold air blow to vacuum pump side from fan side, finally discharge from the exhaust vent of outer housing, this reduces
Temperature in silencing case base and sound insulation groove during vacuum pump operation.
This utility model has considered radiating and the two-way demand of noise reduction, overcomes during conventional vacuum pump operation with stream
The increase of amount and noise is bigger, the too high, shortcoming that superficial dust pollute environment big by such environmental effects of pump body temperature, vacuum
Within the specific limits, noise reduction substantially, is applied to 40m for the noise control of pump3/ h～60m3The vacuum pump operation of/h can make noise
Reduce 5dB～10dB, the temperature rising value of vacuum pump keeps constant simultaneously, medical treatment and the fine vacuum of electron trade, height can be met
Flow and the demand of low noise.
