Description
Technical field
This utility model relates to vacuum pump technology field, specifically a kind of Double-stage rotary vane vacuum pump.
Background technology
Vacuum pump is widely used in metallurgy, machinery, military project, electronics, chemical industry, light industry, oil and medicine etc. produce and scientific research department, in the equipment obtaining vacuum, rotary-vane vaccum pump is because of simple in construction, compact, package size is little, and its functional reliability is high, easy to use, the advantage such as ease of maintenaince, it it is currently used vacuum pump widest in area, but single-stage rotary vane type vacuum pump vacuum is the highest at present, ultimate pressure is little, can only obtain coarse vacuum, it is unsuitable for the situation high to vacuum level requirements, cause range little, vacuum pump noise in running is big simultaneously, reduce working environment quality.
Utility model content
In order to solve above-mentioned technical problem, this utility model provides a kind of simple in construction, reasonable in design, and vacuum is high, range is wider, the Double-stage rotary vane vacuum pump that practicality is good.
This utility model is by the following technical solutions: a kind of Double-stage rotary vane vacuum pump, including the pump housing, the first pump chamber and the second pump chamber it is provided with in the described pump housing, the described pump housing is provided with the air inlet pipe connected with the first pump chamber, the first row QI KOU of described first pump chamber is connected by series winding passage and the second pump chamber, described second pump chamber is provided with second exhaust port, blade is had in described first pump chamber and the second pump chamber, blade spring and rotor, described blade is located on rotor, the cylindrical of described rotor is tangent with the inner surface of pump chamber, blade spring it is provided with in blade, blade is close to pump chamber inwall by blade spring, when the rotor rotates, all the time the inwall along pump chamber slides.
Preferably, described blade is three pieces, is uniformly distributed on the central plane of rotor.
Further, described air inlet pipe top is provided with drainage screen.
Further, the medial wall of the described pump housing is provided with noise reduction layer.
Further, it is provided with fin outside the described pump housing.
This utility model advantage is: 1, use the design of twin-stage rotary vane type in the pump housing so that the ultimate pressure of vacuum pump is increased, and can obtain condition of high vacuum degree；2, the noise reduction layer of pump housing inwall, it is possible to effectively absorb the noise that vacuum pump produces, improve working environment；3, the purpose of continuous air extraction can be realized, be greatly improved work efficiency.4, air inlet pipe top is provided with drainage screen, can be kept off outside by dust impurity so that vacuum is clean, has purified corrosion class air, has extended service life of vacuum pump.5, this Double-stage rotary vane vacuum pump simple in construction, reasonable in design, and range is wider, and practicality is good.
