Description
Technical Field
The utility model relates to an electric vacuum pump part technical field especially relates to an increase vacuum pump stator device of passageway of ventilating.
Background
The working principle of the existing electric vacuum pump is that gas is sucked into a stator cavity, the gas is compressed and discharged by a blade rotor, a stator device needs to be improved for the high-power electric vacuum pump, the gas pumping and exhausting efficiency is improved, and if a discharge channel after the gas is compressed is fixed, the gas pumping and exhausting efficiency is hardly improved.
Chinese patent publication, "a new vacuum pump", patent publication No. CN 206647265U discloses a vacuum pump, the stator device of which has two exhaust passages, and it is difficult to improve the exhaust efficiency without improving the structure.
Disclosure of Invention
The utility model aims at providing a simple structure, increase the passageway of ventilating on prior art's basis, improve the vacuum pump stator device of the increase passageway of ventilating of exhausting air extraction efficiency.
In order to realize above-mentioned purpose, the utility model discloses a following technical scheme, an increase vacuum pump stator device of passageway of ventilating, including stator seat, stator lid, stator seat, stator lid pass through the bolt order fixed together, the stator seat is equipped with the air inlet duct, the stator lid is equipped with the air discharge duct, the stator be ring shape, be equipped with the supplementary air discharge duct parallel with the ring axis in the stator circumference wall, the stator seat be equipped with and cover the supplementary air discharge duct that the air discharge duct corresponds with the stator, supplementary air discharge duct be equipped with the interface channel with supplementary air discharge duct one end, the stator lid be equipped with the exhaust hole that corresponds with supplementary air discharge duct, supplementary air discharge duct other end and stator lid exhaust hole intercommunication.
In the prior art, the position of an air inlet slot on a stator seat is close to the maximum volume of a pump chamber, the position of an air outlet slot on a stator cover is close to the minimum volume of the pump chamber, and an air outlet channel is from the minimum volume of the pump chamber to an air outlet slot of the stator cover; therefore, two ventilation channels are added in the scheme, namely two through holes are arranged on the circumferential wall of the stator to serve as auxiliary exhaust channels, the exhaust groove is formed in the stator seat corresponding to the minimum volume of the pump chamber and communicated with the auxiliary exhaust channels, the auxiliary exhaust channels are communicated with the exhaust holes which are added on the stator cover, so that a newly-added ventilation channel is formed, and the exhaust and air extraction efficiency can be improved under the condition that the power of the electric vacuum pump is increased without changing other structures.
The beneficial effect of this scheme is: simple structure, increase the passageway of ventilating, improve the exhaust efficiency of bleeding, under the unchangeable condition of overall structure, can adapt to and satisfy more powerful service conditions.
