General expression centrofugal compressor structure is: compressor form is four sections of level Four, and centrifugal compressor is made up of rotor, stator and bearing etc.The parts such as impeller are enclosed within main shaft and form rotor, and rotor bearing, on bearing, drives main shaft High Rotation Speed by motoring speed increaser.Stator comprises the parts such as casing, dividing plate, sealing, suction chamber and outlet volute.The fixed elements such as Diffuser, bend and return channel are formed between dividing plate.Only have the centrifugal compressor of an impeller to be called single-stage radial compressor, what have two or more impeller is called multistage centrifugal compressor, and every one-level is made up of passages such as impeller and Diffusers below thereof.Impeller is the critical component of centrifugal compressor, and impeller is double shrouded wheel, is made up of blade, wheel cap and wheel disc.When impeller High Rotation Speed, due to the interaction of power between blade and gas, the mainly effect of centrifugal force, gas sucks from impeller central, flows to impeller outlet along the runner of passage between blade.Impeller is to air work, and gas obtains energy, and pressure and speed improve.Then, gas flow is through passages such as Diffusers, and speed reduces, and pressure improves further, and namely kinetic energy is pressure energy, finally enters spiral case and transfers out.In whole compression process, the specific volume of gas reduces, and temperature increases.After temperature increases, pressurized gas needs to consume more energy.In order to save power, adopt cooling during rolling, by the level group section of being called that interstage cooler separates.Gas enters interstage cooler by the preceding paragraph, reduces after temperature entering next section of continuation compression again through cooling.Interstage cooler generally adopts water-cooled.
Although the chlorine gas compressor of this structure can use, there is the shortcoming of sealing difference, be not suitable for using as chlorine gas compressor.
Summary of the invention
In order to improve sealing and the efficiency of chlorine gas compressor, the present invention proposes the hermetically sealed chlorine centrifugal compressor of a kind of supercharging, this compressor by body adopt labyrinth sealing, nitrogen-sealed, bearing thrust bearing adopt that meter Xie Er profile shaft holds, radial bearing is tilting-pad bearing, often organize bearing has two tile fragments to bury the technological scheme of thermometric thermal resistor and level Four four sections of superchargings underground, solve the technical problem of chlorine gas compressor sealing, supercharging and thermometric and lubrication.
The scheme that technical solution problem of the present invention adopts is:
Common backplane is provided with drive motor, drive motor is connected with compressor body with speed increaser by coupling.Compressor one end is provided with suction chamber, the other end is provided with exhaust chamber, suction chamber and exhaust chamber end are respectively equipped with the labyrinth seal that can pass into nitrogen, impeller shaft one end of compressor is arranged on radial bearing, and the other end is arranged on thrust bearing, and compressor scroll is interconnected to by four sections of level Four and is integrated, an impeller is installed in each spiral case, be equipped with Diffuser in each spiral case, between spiral case, form runner, between one group of spiral case and connected spiral case, be provided with dividing plate.
Nitrogen is passed in labyrinth seal;
Thrust bearing adopts meter Xie Er profile shaft to hold;
Radial bearing is tilting-pad bearing;
