Problems solved by technology

The vacuum pump with traditional structure needs to install two blades to ensure the movement. The structure is complex, and the two ends of the blades directly rub against the inner wall of the pump during operation. Lubricating oil needs to be added to prevent the blades from rubbing against the pump chamber during operation. The product fails, and the vacuum pump with traditional structure cannot be used in the occasion where oil is not allowed

Embodiment

[0021] Such as Figure 1-4 As shown, the dry single vane vacuum pump includes a cover plate 1, a pump body 2, a vane 3, a shaft 4 and a roller 6. The two ends of the vane 3 are processed with a concave arc 5, and the roller 6 is installed in the concave arc 5. The depth of the arc 5 is greater than the diameter of the roller 6, the shaft 4 is installed eccentrically in the pump body 2, a groove and a step are processed on the shaft 4 to install the blade 3 and the roller 6, and the cover plate 1 is installed on the pump body 2 to form a closed pump cavity. Wherein, the inner wall of the pump body 2 is tightly connected with the vane 3 , and the vane 3 gradually moves clockwise from point a to point l on the inner wall of the pump body 2 , that is, the sinusoidal line from point a to point l continuously reciprocates and circulates.

[0022] Such as Figure 5 As shown, when working, when the shaft 4 rotates to drive the blades 3 to rotate, the volume of the pump chamber A inc...

Abstract

The invention belongs to the technical field of a vacuum pump, and particularly relates to a dry type single-blade vacuum pump. The dry type single-blade vacuum pump comprises a cover plate, a pump body, a blade, a shaft and rollers, wherein concave circular arcs are processed in the two ends of the blade; the rollers are arranged in the concave circular arcs; the shaft is eccentrically arranged in the pump body; the blade and the rollers are arranged on the shaft; the cover plate is arranged on the pump body for forming a sealed pump cavity. The single blade is used for completing the vacuumpumping; the structure is simple; the price is low; the air extraction quantity is great; the dry type single-blade vacuum pump can be widely used in the industries of industry, automobiles, chemicalengineering, food, medicine and the like.

Description

technical field [0001] The invention belongs to the technical field of vacuum pumps, in particular to a dry single-blade vacuum pump. Background technique [0002] A vacuum pump is a device that can extract the gas in a closed container to make the container reach a certain vacuum pressure. The vacuum pump with traditional structure needs to install two blades to ensure the movement. The structure is complicated, and the two ends of the blades directly rub against the inner wall of the pump during operation. Lubricating oil needs to be added to prevent the blades from rubbing against the pump chamber during operation. The product fails, and the vacuum pump with traditional structure cannot be used in the occasion where oil is not allowed. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the present invention designs a dry-type single-blade vacuum pump, which uses a single blade to complete vacuuming. It has a simple structure...
