Preferably, diversion groove 30 is one or more, and one or more diversion grooves 30 are arranged along the periphery of installation portion 11,
Ensure that the coolant within deafener 20 can be discharged to the outside of deafener 20 swimmingly, make compression cylinder 50 by diversion groove 30
The gases at high pressure discharged are more uniform, it is possible to decrease the microseismic noise of gases at high pressure, the aerodynamic noise of high pressure is less, and can effectively keep away
Open the impact between the pulsed gas of high pressure and the rotor 60 of high speed rotating, friction, be effectively reduced the aerodynamic noise of compressor,
Compressor overall noise is made also to have substantially reduction.It is highly preferred that the number of diversion groove 30 is at 1 to 6, such as 4,
Avoid diversion groove 30 to offer and too much affect the machine structural strength of installation portion 11.
Preferably, the installation portion 11 of the present embodiment is the tubular structure being arranged on bent axle 40 periphery, simple in construction, it is simple to water conservancy diversion is recessed
The offering and processing of groove 30.
In the present embodiment, deafener 20 is hermetically sealed noise-reducing structure, and the axle only coordinated with deafener 20 at installation portion 11 is surveyed and opened
If circumference arc groove or axial groove, the gases at high pressure that compression cylinder 50 is discharged enter hermetically sealed deafener 20 space of expansion,
The noise energy that high pressure draught pulsation is produced effectively is discharged.
Meanwhile, the gases at high pressure got rid of in compression cylinder 5, directly by installation portion 11 circumferential grooves or axial groove after eliminating the noise
Getting rid of, compressor air-discharging is more smooth and easy, and compressor extra work is few so that compressor power consumption is low, effectively raises pressure
Contracting function is imitated, and the structure of groove can adjust different forms according to the noise power consumption actual demand of compressor, as shown in table 1,
The refrigerating capacity of compressor when wherein table 1 shows and arranges different groove, power, relation between COP and noise.
Table 1:
According to data above it is recognised that the structure of the present invention can effectively reduce the noise of compressor and reduce compressor
Energy consumption, improves the performance of compressor.
Deafener 20 is hermetically sealed noise-reducing structure, arranges the axle survey coordinated with deafener 20 and offer on the installation portion 11 of flange 10
First groove 31 or the second groove 32, under the effect of deafener 20 so that the noise energy that high pressure draught pulsation produces obtains
Effectively release, then discharge from the first groove 31 or the second groove 32.Made from compression by the first groove 31 or the second groove 32
The gases at high pressure that cylinder 50 is discharged are more uniform, it is possible to decrease the microseismic noise of gases at high pressure, the aerodynamic noise of high pressure is less, and can
Effectively avoid the impact between the pulsed gas of high pressure and the rotor 60 of high speed rotating, friction, be effectively reduced the gas of compressor
Moving noise so that compressor overall noise also has substantially reduction.
Meanwhile, the gases at high pressure that compression cylinder 50 is got rid of, directly discharged by the first groove 31 or the second groove 32 after eliminating the noise,
Making compressor air-discharging more smooth and easy, compressor extra work is few so that compressor power consumption is low, is effectively improved compression
Function is imitated, and the structure of the first groove 31 or the second groove 32 can adjust difference according to the noise power consumption actual demand of compressor
Form.
