Description
Technical field
The present invention relates to vacuum pump technology field, in particular to a kind of Vehicular electric diaphragm vavuum pump.
Background technology
Vehicular electric vavuum pump mainly has piston type vacuum pump, rotary-vane vaccum pump and diaphragm vavuum pump at present.Although film
Chip vavuum pump in reliability and Energy Efficiency Ratio far better than piston type and rotary-vane vaccum pump, but because traditional diaphragm is true
Empty pump volume is more huge, and limited frequently result in space can not install and use on car.
Such as application publication number be CN 105889041 A, CN 105952624 A, CN 105889042 A middle promulgated by the State Council
Bright patent, disclosing diaphragm type electric vacuum pump for automobile and parts includes motor and the pump housing, and intake and exhaust are offered on the pump housing
Road, left and right end-cap assembly is provided with the left and right ends of the pump housing, left and right end-cap assembly is internally provided with suction muffler and discharge chamber, entered
Exhaust duct is respectively communicated with the suction muffler of left and right end-cap assembly, discharge chamber, and outlet port cap assemblies include end cap and shield, end cap with
Shield forms first-level buffer chamber and level 2 buffering chamber, is provided with end cap check valve in first-level buffer intracavitary, level 2 buffering intracavitary has suction
Sound sponge, gas are discharged by steam vent again by the entering and exhaust channel of the pump housing.This several prior art disclosures have pumping
Performance is more preferable, and noise is smaller, and safety coefficient is higher, and service life is longer, and cumulative operation time can reach more than 1200 hours.On
State several prior arts and although solve that traditional diaphragm vavuum pump volume is more huge, and limited frequently result in space can not on car
The problem of installing and using, but left and right end-cap assembly and lateral plate structure are complex, and processing, assembling are all complex；In addition, side plate
Lack seal between end cap, sealing effectiveness is bad, and pumping efficiency is low.
The content of the invention
In order to solve above-mentioned technological deficiency existing for prior art, it is an object of the invention to provide a kind of Vehicular electric film
Piece vavuum pump, solve the problems, such as that complicated, pumping efficiency is low in the prior art.
