Embodiment
It is that the following description is substantially merely exemplary and be not intended to limit the disclosure, application or purposes.Below
The embodiment of the utility model Vehicular electric diaphragm vavuum pump is further described with reference to Figure of description.
As Figure 1-Figure 4, according to the structural representation of Vehicular electric diaphragm vavuum pump of the present utility model.It is a kind of automobile-used
Electronic diaphragm vavuum pump, including motor 1, crankcase 2, bonnet 3, valve plate 4, connecting rod 6, silencer 9 and suction joint 11, motor 1
Direct connection drives eccentric shaft 10；The 6 symmetrical distribution of bonnet 3, valve plate 4 and connecting rod, the end of connecting rod 6 are provided with diaphragm 7, the bonnet
Sealed between 3 and valve plate 4 provided with special-shaped seal ring 5, pumping efficiency is high.
Vehicular electric diaphragm vavuum pump of the present utility model, which has, to operate steadily, and pumping efficiency is high, compact-sized, volume
It is small, in light weight, the advantages that being easily installed arrangement.
Vehicular electric diaphragm vavuum pump of the present utility model uses horizontally-opposed structure, the direct connection of motor 1 driving eccentric shaft 10
Rotation, by the transmission of connecting rod 6, diaphragm 7, connecting rod 6 just move reciprocatingly, the work being made up of valve plate 3 and connecting rod 6, diaphragm 7
Volume then can generating period change.When diaphragm 7, connecting rod 6 are from outer dead point to lower dead center setting in motion, swept volume gradually increases
Greatly, now gas i.e. along suction joint 11, is pushed the air-intake valve plate on special-shaped seal ring 5 open and entered in working chamber, Zhi Daogong
Untill when changing to maximum as volume, air-intake valve plate closing air inlet.When connecting rod 6 when diaphragm vavuum pump, 7 counter motion of diaphragm,
Swept volume is reduced, gas pressure rise, and the exhaust valve plate on special-shaped seal ring 5 is pushed open by work intracavity gas, and gas is through pipe
Road is discharged into crankcase 2, and until piston movement is untill extreme position, exhaust outlet is closed.
Said process repeats.In a word, the eccentric shaft 10 of diaphragm vavuum pump rotates a circle, diaphragm 7, connecting rod 6 reciprocal one
