Below with reference to embodiment come the present invention will be described in detail create.
A kind of integrated charge air-cooling system of multistage magnetic suspension turbine vacuum pump, as shown in Figures 1 to 4, including is installed on multistage
Magnetic levitation vacuum pumps the cooling device 2 between higher level's host 1 and vacuum pump junior host 3；The cooling device includes shell 21
And the mounting flange 22 of shell both ends setting, it is disposed with rectification tube bank inside the shell, rectification tube bank is more arranged in parallel and quilts
The rectifying tube 23 rigidly fixed forms, and both ends inside the housing are respectively equipped with fixed each rectifying tube and keep each rectifying tube phase
To the tube bank fixed plate 24 of position, keep each rectifying tube independent (each rectifying tube is arranged in parallel each other) by tube bank fixed plate；
In general, rectifying tube uses seamless round steel pipe.
Tube bank fixed plate is that more than one circular hole thin plate, thereon each circular hole position and each rectifying tube position of tube bank correspond,
Two tube bank fixed plates are inserted in tube bank from tube bank both ends respectively, support the position of each steel pipe in simultaneously Fixed Tube-sheet Reboiler；Restrain each steel pipe
Both ends protrude from corresponding tube bank fixing seal plate.It is sealed between each rectifying tube and tube bank fixed plate, and restrains and fix
It is sealed between plate and shell, the space between two tube bank fixed plates outside each rectifying tube constitutes shell side 25, restrains fixed plate
Space and each rectifying tube inner space between mounting flange outer end face collectively form tube side 26；It should be noted that
Tube side is the region that air flows through, and shell side is the region that cooling water flows through.
Corresponding on the shell to be equipped with water inlet flanged pipe 27 and delivery port flanges pipe 28, this two flanged pipe is and shell
Interior shell side communicates, and than the entrance and exit as cooling water, water inlet flanged pipe is connected to water inlet pipe 4, goes out two flanged pipes point
Mouth of a river flanged pipe is connected to outlet pipe 5.Under working condition, high-temperature gas is flowed through out of tube bank each pipe, and cooling water is outside tube bank
It flows through, high-temperature gas is cooled during flowing through tube bank, while being rectified by rectifying tube arranged in parallel, reduces in air-flow
Vortex optimizes the charge air flow streamline of junior's impeller.
The cooling device that the invention provides is set among the magnetic suspension turbine type vacuum pump host of plural serial stage, on
The high-temperature spiral air-flow of grade turbine vacuum pump discharge reaches junior's magnetic levitation vacuum pump after cooling device cooling, rectification
Air inlet.
The above-mentioned cylindrical structure of shell, mounting flange are welded in the both ends of cylinder-like shell, each equal edge of rectifying tube
Shell axially arranges, mounting arrangements facilitate it is mutually indepedent between each rectifying tube, it is noiseless.
Each rectifying tube stretches out the part on the outside of tube bank fixed plate, is within the mounting flange outer end face, phase
When foring in the tube bank fixed plate in every side and all the sky that certain air temporarily stores and circulate between corresponding host
Chamber, a part of this cavity as tube side can carry out heat exchange with the gas at corresponding side vacuum pump impeller, and can keep away
Exempt from vortex to generate.Standard is done to enter cooling device rectification in space of the cavity of higher level side as interim aggregation high temperature gas flow
It is standby, and the air-flow after being rectified and exchanging heat is assembled out of cooling device junior side cavity, reduces vortex to greatest extent,
Gas circulation stability is good, the operational efficiency of vacuum pump.
Several groups via hole is correspondingly provided in the two tube bank fixed plates, each rectifying tube both ends are corresponding to be passed through
Corresponding via hole, and it is fixedly welded on tube bank fixed plate.The two tube bank fixed plate parallel arrangements, and it is fixedly welded on shell
Inner wall.Tube bank fixed plate not only plays the role of fixed rectifying tube, meanwhile, sealing function is also acted as, interior of shell is isolated
Shell side out, that is, form the cavity passed through for cooling water, cooling water do not overflow between two tube bank fixed plates defined by sky
Between, also, will not flow into rectifying tube.
The invention is reasonable in design, can effectively reduce the temperature of multistage magnetic suspension turbine vacuum pump interstage air,
And the air grade can be rectified, the air-flow vortex of junior's impeller eye is reduced, gas flow loss is reduced, it is true to improve this
The operational efficiency of sky pump.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection scope within.
