Abstract
The present invention proposes a kind of gear type cantilever two-stage water vapour compressor, including main shaft, impeller and gear-box, described main shaft and the one-body molded side being in gear-box of gear-box rotating shaft, two impellers of series connection suit on described main shaft, gear box side is arranged casing and forms compression chamber with impeller.Both stage impellers of the present invention is connected on main shaft, is integrated into gear-box, compact conformation, eliminates the various attachment structures of running part, and efficiency gets a promotion；And using limit of temperature rise wide, the mode of regulation temperature rise is various, is not only limited to regulate rotating speed, and relative normalized degree is higher, medium and saturated temperature rise is up to 20 DEG C～30 DEG C compared with under low discharge, and existing domestic single-stage water vapour compressor is difficult to reach this temperature rise.
Description
Technical field
The invention belongs to device fabrication processing technique field, steam more particularly to a kind of gear type cantilever two-stage water
Vapour compressor.
Background technology
Centrifugal compressor is a kind of universal machine improving gas pressure, and the many departments in national economy are answered
With.Water vapour compressor is as emerging recycle heat reclamation set, and it, by improving the pressure of low-pressure steam, improves saturated temperature
Rising, and steam temperature is stable, can effectively improve the quality of product, efficiency is high, it is only necessary to minimal amount of electric energy, it is possible to
Can be re-used in making substantial amounts of low-pressure steam, efficiency is the highest, reduces energy demand, realizes the energy, material simultaneously
Recycling economy is run.The most domestic medium and the application of relatively low discharge high temperature rise typically single-stage high-speed and Roots.But for
From the point of view of single-stage high-speed, rotating speed is the highest, and the requirement to equipment especially gear-box is the highest, and is difficult to accomplish standardization, reliably
Property and standardization level the highest, cost increases a lot along with the raising of rotating speed, and serious constrains sending out of water vapour compressor
Exhibition.For from the point of view of roots blower, efficiency is low, and reliability is the highest, and noise is big, runs and maintenance cost is the highest.
Summary of the invention
It is an object of the invention to for the deficiencies in the prior art, it is provided that a kind of gear type cantilever two-stage water vapour compression
Machine, be that a kind of compression efficiency is high, cost squeeze is low, standardization level is high, performance safety good reliability, length in service life, in
Deng flow, the saturated temperature rise steam centrifugal compressor up to 20 DEG C～30 DEG C.
The present invention realizes particular by techniques below scheme:
A kind of gear type cantilever two-stage water vapour compressor, including main shaft, impeller and gear-box, described main shaft and gear-box
The one-body molded side being in gear-box of rotating shaft, on described main shaft series connection suit two impellers, gear box side arrange casing and with
Impeller forms compression chamber.
Preferably, each impeller is respectively at a compression chamber, and two compression chambers are respectively communicated with.
Preferably, at least one during impeller is three-dimensional flow double shrouded wheel, half-opened impeller.
Preferably, one, described impeller is three-dimensional flow double shrouded wheel, and another is half-opened impeller.
Preferably, described impeller is all three-dimensional flow double shrouded wheel.
Preferably, described impeller is all half-opened impeller.
What the present invention produced has the beneficial effect that present configuration is compact, and main shaft is directly integrated on gearbox shaft, saves
Two bearings of rotor part, reduce assembly difficulty, improve overall efficiency, good energy-conserving effect, three-dimensional flow design blade effect
Rate is high, and two stages of compression pressure ratio is big, temperature rise, and standardization level is high, and under identical temperature condition, rotating ratio single-stage is low, reduces into
This, variable ratio frequency changer regulates, and speed variation is wide, gear up, is adapted to different operating modes, and efficiency is high, medium and relatively rill
Under amount, saturated temperature rise is up to 20 DEG C～30 DEG C.
