Lifting self-speed-regulating impeller device for steam compressor

Abstract

The invention discloses a lifting self-speed-regulating impeller device for a steam compressor, and belongs to the technical field of steam compressors. The vertical column is fixedly arranged on the machine frame plate, the impeller is arranged on the vertical column in a sliding and rotating mode, the impeller rotation driving mechanism drives the impeller to rotate, the impeller lifting driving mechanism drives the impeller to do lifting motion, and the driving motor is arranged on the machine frame plate. The impeller rotation driving mechanism comprises a worm, a gear shaft, a bevel gear A, a gear locking spring and a bevel gear B; the impeller lifting driving mechanism comprises a worm gear, an arc-shaped gear, a composite rack, a lifting sleeve, a gravity balance spring, a reversing pulley B, a reversing pulley A, a traction rope and a sliding guide rod. The lifting self-speed-regulating impeller device is reasonable in structure, has the lifting self-speed-regulating function that the higher the position is, the higher the rotating speed is, and can remarkably improve the heating effect and the heating efficiency of the steam compressor.

Description

technical field [0001] The invention mainly relates to the field of steam compressors, in particular to an ascending and descending self-speed-regulating impeller device for steam compressors. Background technique [0002] The steam compressor can compress the secondary steam to increase its enthalpy to replace the fresh steam as the heat source of the heat exchanger, so it is widely used in many industries. As an important part of the compressor, the impeller's structural characteristics and working mode are closely related to the working efficiency and effect of the compressor. The internal flow properties of the fluid cause the temperature difference problem of high temperature on the upper side and low temperature on the lower side in the steam chamber of the compressor along its height direction, and the existing compressor impeller cannot move up and down during the rotation process, so the existing technology cannot solve the problem of steam The problem of indoor te...

AI Technical Summary

Problems solved by technology

The internal flow properties of the fluid cause the temperature difference problem of high temperature on the upper side and low temperature on the lower side in the steam chamber of the compressor along its height direction, and the existing compressor impeller cannot move up and down during the rotation process, so the existing technology cannot solve the problem of steam The problem of indoor temperature difference, that is, the steam discharged from the steam room has the defect that the calorific value fluctuates greatly; in addition, the rotation speed of the existing compressor impeller has nothing to do with the high and low positions of the impeller, which makes higher temperature steam and lower temperature The steam has the same volume flow, which reduces the working efficiency of the compressor
