Abstract
The utility model discloses a kind of noise reduction devices of magnetcisuspension floating centrifugal unit, including compressor, condenser, economizer, throttle valve and evaporator, the compressor, condenser, economizer, throttle valve and evaporator are sequentially connected composition circulation loop by pipeline, there is electrically operated valve by piping connection between the condenser and evaporator, the compressor, condenser, economizer, throttle valve, evaporator and electrically operated valve are connect with the control host of magnetcisuspension floating centrifugal unit.Noise reduction device provided by the utility model, it may make magnetcisuspension floating centrifugal unit operating condition that can run in deviation theory design conditions, will not that there is a phenomenon where noises is larger, effectively overcome in the prior art magnetic suspension centrifugal compressor there is the relatively large defect of vibrating noise.
Description
Technical field
The utility model relates to magnetcisuspension floating centrifugal machine set technology field more particularly to a kind of magnetcisuspension floating centrifugal units
Noise reduction device.
Background technique
With the rapid development of our country's economy, energy availability and demand contradiction is more and more prominent, and the pressure that environment is born is also more next
Heavier, the magnetcisuspension floating centrifugal unit of high energy efficiency ratio comes into being therewith and is gradually commercially available universal.Currently, magnetic suspension
The centrifugal frequent problem of unit is exactly that unit operates in vibrating noise operation area, the shake of magnetic suspension centrifugal compressor
Dynamic noise is relatively large.
Utility model content
In order to overcome the deficiencies of the prior art and there are the problem of, the utility model provides a kind of magnetcisuspension floating centrifugal unit
Noise reduction device, so that the vibrating noise phenomenon of magnetic suspension centrifugal compressor is minimized.
The utility model is achieved through the following technical solutions: a kind of noise reduction device of magnetcisuspension floating centrifugal unit,
Including compressor, condenser, economizer, throttle valve and evaporator, the compressor, condenser, economizer, throttle valve, with
And evaporator is sequentially connected composition circulation loop by pipeline, has between the condenser and evaporator by piping connection electronic
Valve, the compressor, condenser, economizer, throttle valve, evaporator and electrically operated valve with magnetcisuspension floating centrifugal unit
Control host connection.
Preferably, the pipeline is copper tube or seamless steel pipe；The evaporator is spiral tube evaporator, vertical pipe type steaming
Send out device or horizontal-type evaporator.
Preferably, the condenser is aerial condenser, ball condenser, coil condenser, straight type condenser or submergence
Condenser.
Preferably, the throttle valve is through type throttle valve or Angle Throttle Valves.
Compared with prior art, noise reduction device provided by the utility model may make magnetcisuspension floating centrifugal unit to transport
Row operating condition can be run in deviation theory design conditions, will not that there is a phenomenon where noises is larger, effectively overcome magnetic in the prior art
There is the relatively large defect of vibrating noise in suspension centrifugal compressor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of noise reduction device described in the utility model embodiment.
Specific embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments to the utility model make into
One step detailed description.
As shown in Fig. 1, a kind of noise reduction device of magnetcisuspension floating centrifugal unit, including compressor, condenser, economy
Device, throttle valve and evaporator, the compressor, condenser, economizer, throttle valve and evaporator are successively connected by pipeline
Composition circulation loop is connect, has electrically operated valve, the compressor, condensation by piping connection between the condenser and evaporator
Device, economizer, throttle valve, evaporator and electrically operated valve connect with the control host of magnetcisuspension floating centrifugal unit and receive control
The control of host processed.
In a wherein preferred embodiment, the pipeline is copper tube or seamless steel pipe；The evaporator is spiral
Tubular evaparator, vertical-type evaporator or horizontal-type evaporator；The condenser is aerial condenser, ball condenser, coil pipe
Condenser, straight type condenser or submergence condenser；The throttle valve is through type throttle valve or Angle Throttle Valves.
In the present embodiment, the component for realizing noise-reducing is mainly electrically operated valve and is connected between condenser and evaporator
Pipeline, the switch state of electrically operated valve is by control host control；The pre-set magnetcisuspension floating centrifugal machine in control host
Group vibrating noise range of operation works.When magnetcisuspension floating centrifugal unit works normally, the flow direction of the circulation loop is successively
Are as follows: compressor, condenser, economizer, throttle valve, evaporator return compressor；When magnetcisuspension floating centrifugal unit operates in shake
In dynamic noise operation area, electrically operated valve opening is immediately controlled in control host, so that magnetic suspension centrifugal compressor is avoided shaking
Noise operation area, the flow direction of the circulation loop is successively at this time are as follows: compressor, condenser, electrically operated valve, evaporator return
Compressor；When magnetcisuspension floating centrifugal unit operates in outside vibrating noise operation area, electrically operated valve pass is immediately controlled in control host
It closes, the flow direction of the circulation loop restores flow direction when working normally at this time.
Noise reduction device provided in this embodiment may make magnetcisuspension floating centrifugal unit operating condition that can manage deviateing
Run by design conditions, will not that there is a phenomenon where noises is larger, effectively overcome in the prior art magnetic suspension centrifugal compressor go out
The existing relatively large defect of vibrating noise.
Above-described embodiment is the preferable implementation of the utility model, is not the restriction to the utility model, not
Be detached from the utility model inventive concept under the premise of, it is any it is obvious replacement the protection scope of the utility model it
It is interior.
