Abstract

The invention discloses a multi-stage high-speed centrifugal type vapor compressor, and relates to the field of chemical mechanical equipment. According to the multi-stage high-speed centrifugal type vapor compressor, a gear shifting hole is formed in the side surface of a box body of a gearbox; a gear-shifting supporting frame is arranged on a position, corresponding to the gear shifting hole, in the gearbox; a drive shaft is arranged between the gear shifting hole and the gear-shifting supporting frame; a drive gear is fixed on the drive shaft; a driven shaft is further fixed in the gearbox; a driven multi-stage gear is fixed on the driven shaft; the driven multi-stage gear is mutually engaged with the drive gear; and the drive shaft is manually shifted between the gear shifting hole and each semicircular hole corresponding to the gear-shifting supporting frame to achieve the multi-stage gear-shifting transmission purpose. The multi-stage high-speed centrifugal type vapor compressor is convenient in operation, reliable in gear shifting, and can meet multi-stage transmission requirements of the vapor compressor.

Description

technical field [0001] The invention relates to the field of chemical machinery equipment, in particular to a multi-stage high-speed centrifugal steam compressor. Background technique [0002] The steam compressor is the key equipment for the heat recovery system to increase the temperature and pressure of the steam by compressing the generated steam. Its function is to pressurize and heat up the low-pressure or low-temperature steam to meet the temperature and pressure requirements required by the process or project. . The steam compressor is mainly composed of three main units: the compression system, the steam desuperheater and the lubrication system. [0003] Most of the existing steam compressors are designed as a single stage, and the impeller of the steam compressor has only one speed and cannot be adjusted, and the speed of the impeller is generally not high, which cannot meet the requirements of modern industry for multi-stage variable speed of the steam compressor...
