Abstract
The invention discloses a noise reducing device of scroll compressor, comprising a sealed casing, a static scroll disk fixed in the sealed casing, a dynamic scroll disk fixed on the driving shaft, an outlet cover fixed on the static scroll disk and forming an out let chamber, and a high-low pressure dividing plate which divides the sealed casing into suction area and outlet area. The invention is characterized in that: on the outlet cover, multiple small through holes are formed, the compressed gas from the compressing chamber can be outlet by the small through holes. In this way, the outlet path of the compressed gas is dispersed. The invention can reduce the pulsating pressure of the compressed gas, and consequently reduced the noise from the compressor.
Description
Technical field
The invention belongs to a kind of equipment that scroll compressor is discharged noise that reduces, be specifically related to a kind of a kind of device that reduces scroll compressor discharge noise of dual support vertically.
Background technique
In general, turbocompressor is widely used in the field of air regulator, compressor as the high efficiency low noise, its mode of operation is that two turbines are carried out relative rotatablely moving, make to form a plurality of paired pressing chambers between the turbine, this pressing chamber moves to central direction rapidly, meanwhile, smaller volume, thus compress after the suction that cold media air is continuous and discharge.As Fig. 1, shown in 2, the formation of existing scroll compressor is: the seal casinghousing of turbocompressor (1), on the lower shell body (1a) of seal casinghousing (1), be provided with gas suction pipe (SP), on the upper shell (1b) of seal casinghousing (1), be provided with gas outlet pipe (DP), main frame (2) and auxiliary frame (not shown) are separately fixed at the both sides up and down in the seal casinghousing (1), between main frame (2) and auxiliary frame (not shown), drive motor (3) is installed, be pressed into the gyrator center of motor (3), thereby the motor (3) and the live axle (4) of main frame (2) have been connected, movable orbiting scroll (5) be positioned at the top of main frame (2) and and live axle (4) be fixed together, the scrollwork (5a) of movable orbiting scroll (5) is bitten combination and has been formed the scrollwork (6a) of screw type in order to form multiple compressing chambers (P), quiet whirlpool dish (6) be fixed on main frame (2) above, the high low pressure separating plate (7) that is positioned at dish (6) back side, quiet whirlpool is suction area (S1) and discharge zone (S2) with the internal separation of seal casinghousing (1); Discharge cover (8) be fixed on quiet whirlpool dish (6) above, discharge cover (8) and coil between (6) with quiet whirlpool and formed discharge chamber (V).Have at the center of quiet whirlpool dish (6) and discharge the exhaust port (6c) that chamber (V) is communicated with.
Lower shell body (1a) and upper shell (1b) welding are fixing, its inner edge has formed the through hole (6b) (not shown) of suitable number, and bolt (B) coils quiet whirlpool (6), demarcation strip (7) and discharges cover (8) three and links together and formed ring-like disc-shape.Discharge cover (8) and make, have gas via-hole (8a) in the middle with steel plate.Middle part at quiet whirlpool dish (6) has exhaust port (6c).Be installed in reverse stop valve assemblying body (9) on the quiet whirlpool dish (6) and make the cold media air can only one-way flow, O be a seal ring.
The running of existing turbocompressor is as follows:
Turn on the power switch, live axle (4) will rotate jointly with drive motor (3), movable orbiting scroll (5) rotates to off-centre (centrifugal) distance, meanwhile, the scrollwork (5a) of movable orbiting scroll (5) and quiet whirlpool dish (6) forms a plurality of paired pressing chambers (P) between (6a), each is to pressing chamber (P) rotatablely moving rapidly along with movable orbiting scroll (5) then, and move to the center, thereby volume reduces, and after cold media air is drawn into pressing chamber (P) and is compressed to certain pressure, discharge to the discharge chamber (V) of discharging cover (8) by exhaust port (6c).This process is carried out repeatedly.At this moment, as shown in Figure 2, to discharge the pressurized gas of discharging chamber (V) its discharge empathize and make a noise in the chamber (V) after, discharge to the discharge zone (S2) of seal casinghousing (1) by gas via-hole (8a), discharge to the condenser of freeze cycle by gas outlet pipe (DP) once more, this process is also carried out repeatedly.
But, in the aforesaid existing scroll compressor, pressurized gas is discharged to the discharge chamber (V) of discharging shell (8), pass through a gas via-hole (8a) once more in the process that the discharge zone (S2) of seal casinghousing (1) is discharged, because the stream of pressurized gas is concentrated and has been produced fluctuation pressure simultaneously, produces the problem of compressor noise thus.
Summary of the invention
The objective of the invention is to discharge the problem that the noise device exists, a kind of stream that can provide dispersion to discharge gas is provided, reduce fluctuation pressure, thereby can reduce the device of the discharge noise of turbocompressor in order to solve existing scroll compressor.Technological scheme of the present invention is as follows: a kind of device that reduces the discharge noise of turbocompressor comprises and is provided with exhaust port (or discharge zone) and is fixed on quiet whirlpool dish in the seal casinghousing, with quiet whirlpool dish meshing and can with together that move and that the form a plurality of pressing chambers continuously movable orbiting scroll of movable orbiting scroll, with the internal separation of seal casinghousing is the high low pressure demarcation strip of suction area and discharge zone, formed the discharge chamber of the exhaust port that holds quiet whirlpool dish, the device of the minimizing scroll compressor discharge noise that constituted of the discharge cover etc. of a plurality of tiny through holes of having discharged formation that the chamber is communicated with the discharge zone of seal casinghousing.
