Embodiment Construction

[0016] Embodiments of the present invention are further described below in conjunction with accompanying drawings:

[0017] Such as Figure 1-Figure 3 As shown, the rotor of the Roots-type steam compressor of the present invention includes a rotor body 4 with a cross-section of "8" shape, grooves 3 are formed in parallel at regular intervals on the sealing surface of the rotor body 4, and the grooves 3 are installed There is a sealing strip 2 matching the groove 3, and the sealing strip 2 is made of C, H, F, and Si cross-linked composites. There is a small hole 5 on the bottom surface of the sealing strip 2, and one end of the wire-wound spring 1 is installed in the small hole 5 Inside, the other end abuts against the bottom surface of the groove 3, so that the sealing strip 2 protrudes from the surface of the rotor body 4, and the expansion gap is preset between the rotor body 4 and the casing. The grooves 3 are parallel to the axis of the rotor body 4, and the distance betw...

Abstract

The invention relates to a rotor of a Roots type vapor compressor, and belongs to the field of vapor compression. The rotor comprises a rotor body the cross section of which is 8-shaped, wherein the sealing surface of the rotor body is parallelly provided with grooves at a certain interval; the grooves are internally provided with sealed strips matched with the grooves, the bottom surfaces of the sealed strips are provided with small holes, one ends of filament winding springs are arranged in the small holes, and the other ends of the filament winding springs prop against the bottom surfaces of the grooves; and the sealed strips are protruded out of the surface of the rotor body, and an expansion clearance is preset between the rotor body and a shell. The Roots type vapor compressor provided by the invention has the advantages that a clamping phenomenon of the rotor and the shell is greatly reduced, a sealing effect is good, and an energy-saving effect is notable.

Description

technical field [0001] The invention relates to a Roots type steam compressor rotor, which belongs to the field of steam compression. Background technique [0002] Due to its relatively low temperature, secondary steam cannot be used as a heat source for heating solutions at the same temperature. In order to save energy, in recent years, mechanical compression is often used to compress the low-temperature secondary steam, and it can be used as a heat source again after raising the temperature. At present, there are two main vapor compression machines, Roots type and centrifugal type, and the traditional Roots type vapor compressor is directly applied from the air Roots blower without improvement. Higher, only about 0.2mm, and the steam medium carries heat and runs at a higher temperature, which often causes the rotor and the casing to be stuck due to the thermal expansion of the rotor, which affects the stable operation of the equipment. Therefore, some compressors connect t...
