Problems solved by technology
This type of compressor is sealed by a contact line between the blades and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the blades, the rotor and the cylinder body during rotation, resulting in overall wear of the compressor. Fast, short life, low efficiency

Embodiment Construction
[0041] Such as Figure 16 As shown, the cylindrical vane compressor of the present invention includes a housing 1 , a rotor 2 , two vanes 3 , two sealing strips 4 , two gas distribution cones 5 and two gaskets 6 . The rotor 2 is located in the center, the housing 1 is located outside, the two gas distribution cones 5 are respectively located in the hollow conical surfaces at both ends of the rotor 2, and the two vanes 3 are respectively located on both sides of the rotor 2 and placed on the opposite corners of the housing 1. It forms an angle with the rotor 2 in the hollow ring (that is, the guide groove), and the tangent of the angle is the ratio of the height of the housing 1 to the diameter of the bottom circle of the housing 1. One plane of the vane 3 fits the side of the conical table of the gas distribution cone 5, the sealing strip 4 is located between the rotor 2 and the vane 3, one plane side of the blade 3 is jointed with a plane of the rotor 2, and the cylindrical s...

The invention discloses a cylindrical vane type compressor, which comprises a shell, a rotor, two vanes, two sealing strips, two oil distribution cones and two cushion blocks, wherein the rotor is located at the center; the shell is located outside; the two oil distribution cones are respectively located in hollow conical surfaces at two ends of the rotor; the two vanes are respectively located at two sides of the rotor and placed in diagonal hollow circular rings of the shell so as to form an angle with the rotor, and the tangent of the angle is the ratio of the shell height to the bottom circle diameter of the shell; one plane of each vane is stuck to the truncated cone side surface of each oil distribution cone; the sealing strips are located between the rotor and the vanes, the plane side of each sealing strip is stuck to one plane of the rotor, and the cylindrical side of the sealing strip is stuck to the cylindrical surface E1 of each vane; the cushion blocks are located in the diagonal hollow circular rings of the shell, and are just filled in the gap formed by the vanes, the rotor and the sealing strips. According to the invention, all sealed positions are of face seal, the efficiency is high, the specific power is high, the structure is compact, the processing is relatively easy, the cost is lower and the life is long.
Description
technical field [0001] The invention relates to a compressor, in particular to a cylindrical vane compressor. Background technique [0002] The structure of the existing vane compressors is that the rotor is eccentrically placed in the cylinder body, and the vanes are placed in the rotor radially or at a certain angle with the rotor radius. The body forms a sealed cavity, and the volume change generates pressure when it rotates. The number of leaves is two or more. This type of compressor is sealed by a contact line between the blades and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the blades, the rotor and the cylinder body during rotation, resulting in overall wear of the compressor. Fast, short life, low efficiency. In addition, in order to ensure that the blades can safely enter and exit the rotor during rotation, the rotor must have a considerable diameter, so the displacement is bound to b...
