Abstract
The invention provides a sliding-vane rotary vacuum pump. The sliding-vane rotary vacuum pump comprises a pump body and an eccentric rotor, wherein a cylindrical working chamber is arranged in the pump body; the eccentric rotor is a cylinder which is tangent to the working chamber; a rotary vane channel is formed in the eccentric rotor; a telescopic rotary vane is perforated in the rotary vane channel; two ends of the telescopic rotary vane prop against the inner wall of the working chamber; an air suction opening and an air exhaust opening are also formed in the working chamber; a tangent part between the eccentric rotor and the working chamber is located between the air suction opening and the air exhaust opening. When the eccentric rotor rotates clockwise, the volume of an air suction cavity near the air suction opening is greatly increased, and the pumping is started; after the pumping is ended, the chamber rotates over the position of the air suction opening and becomes an isolation chamber; when the chamber rotates to the position of the air exhaust opening again, air is exhausted outside the air exhaust opening in the process of gradually decreasing an air exhaust chamber, and the pumping is completed.
Description
Technical field
The present invention relates to field of vacuum, be specifically related to a kind of sliding vane rotary vacuum pump.
Background technique
Vacuum pump is a kind of rotating volume-varying gas transfer pump, vacuum pump must have fore pump to coordinate to use and in wider pressure range, have larger pumping speed, in gas, contained dust and water vapor is insensitive to extracting, be widely used in the industries such as metallurgy, chemical industry, food, electronics plated film.Current vacuum pump mostly adopts service intermittent mode, can't realize continuously-running duty.
Summary of the invention
Object of the present invention provides sliding vane rotary vacuum pump, solves the even problem of mass flow discrepancy in above-mentioned prior art problem.
The invention provides sliding vane rotary vacuum pump, comprise the pump housing, eccentric rotor, in the pump housing, establish cylindrical body active chamber, eccentric rotor is and the cylindrical body of the tangent setting of active chamber, in eccentric rotor, be provided with blade passage, stretch in blade passage and be equipped with flexible blade, the two end part of flexible blade prop up active chamber inwall, active chamber is also provided with intakeport and relief opening, eccentric rotor and the tangent place of active chamber between intakeport and relief opening.
In the time that eccentric rotor clockwise rotates, increase gradually near the air aspiration cavity volume of intakeport, start suction; Complete after suction, this cavity has turned over the position of intakeport, becomes separate cavities; Turn to again relief opening position time, the process exhaust outside relief opening progressively reducing along with exhaust cavity; Complete suction, realize continuous sucking.
In some embodiments, relief opening is provided with check valve, can improve exhaust pressure, reaches the object of supercharging.
Brief description of the drawings
Fig. 1 is the structural representation of the sliding vane rotary vacuum pump of an embodiment of the present invention.
Embodiment
Below in conjunction with accompanying drawing, sliding vane rotary vacuum pump provided by the invention is described in further detail.
As shown in Figure 1, the invention provides a kind of sliding vane rotary vacuum pump, comprise the pump housing 8, eccentric rotor 6, in the pump housing 8, establish cylindrical body active chamber 10, eccentric rotor 6 is and the cylindrical body of active chamber 10 tangent settings, is provided with blade passage 11 in eccentric rotor 6, stretch and in blade passage 11, be equipped with flexible blade 7, the two end part of flexible blade 7 prop up active chamber 10 inwalls, and active chamber 10 is also provided with intakeport 4 and relief opening 1, eccentric rotor 6 and active chamber 10 tangent places between intakeport 4 and relief opening 1.
Eccentric rotor 6 is isolated three cavity-air aspiration cavitys 3, separate cavities 5 and exhaust cavity 12 with the two ends of stretching blade passage 11 by active chamber 10 with the tangent place of active chamber 10, and above-mentioned three cavitys, all with functional name, can mutually be changed in the rotation process of eccentric rotor 6.In function, with intakeport 4 link up for air aspiration cavity 3, what link up with relief opening 1 is exhaust cavity 12, remaining one is separate cavities 5.
In the time that eccentric rotor 6 clockwise rotates, increase gradually near air aspiration cavity 3 volumes of intakeport 4, start suction; Complete after suction, this cavity has turned over the position of intakeport 4, becomes separate cavities 5; Turn to again relief opening 1 position time, the process progressively reducing along with exhaust cavity 12 is to the outer exhaust of relief opening 1; Complete once suction.
Relief opening 1 is provided with check valve 2, can improve exhaust pressure, reaches the object of supercharging.
The above is only optimal way of the present invention; it should be pointed out that to those skilled in the art, without departing from the concept of the premise of the invention; can also make some similar distortion and improvement, within these also should be considered as protection scope of the present invention.
