Embodiment Construction

[0041] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0042] Such as figure 1 As shown: this embodiment discloses a scroll vacuum pump, including: a vacuum generating device and a driving motor 10, and the driving motor 10 can provide driving force for the vacuum generating device. The part that generates vacuum in the vacuum pump of the vacuum generating device described here.

[0043] The motor shaft of the drive motor 10 includes an integrally formed motor segment 11 and an eccentric shaft segment.

[0044] The motor section 11 described here is located inside the drive motor 10 and assumes the function of the motor shaft, wherein the eccentric shaft section is located inside the vacuum generator and can transmit the kinetic energy of the motor section 11 to the vacuum generator. The device provides the drivi...

Abstract

The invention belongs to the technical field of vacuum pumps and especially relates to a vortex vacuum pump which comprises a vacuum generation device and a driving motor, wherein the driving motor can provide driving force for the vacuum generation device; a motor shaft of the driving motor comprises a motor section and an eccentric shaft section which are integrally formed; the vacuum generationdevice comprises a pump cavity, a movable scroll plate and a corrugated pipe sealing system, and the movable scroll plate is arranged in the pump cavity; the eccentric shaft section is arranged in the pump cavity and can provide power for the movable scroll plate to do translational motion in a compressed air area space in the pump cavity; the corrugated pipe sealing system can completely separate a non-vacuum area which the driving motor is arranged in from the compressed air area space in the pump cavity. The vortex vacuum pump disclosed by the invention has the effects of simple structure,good sealing performance and ability in preventing self rotation of the movable scroll plate.

Description

technical field [0001] The invention belongs to the technical field of scroll vacuum pumps, in particular to a scroll vacuum pump. Background technique [0002] The scroll vacuum pump is a dry vacuum pump, which compresses the gas through the eccentric movement of the moving scroll to achieve the purpose of vacuuming, and belongs to the positive displacement vacuum pump. At present, the most widely used scroll vacuum pump at home and abroad is the double-sided scroll vacuum pump, because the double-sided scroll vacuum pump has a more efficient pumping capacity. [0003] For a vacuum pump, since it is a device used to obtain a vacuum environment, the requirements for the airtightness of the pumping structure are very high. The movable scroll in the inner working chamber of the scroll vacuum pump needs to obtain power through the eccentric shaft to achieve eccentric motion, and the eccentric shaft penetrates most of the parts (including the vacuum working chamber and the non-...
