Background technique
In freezer compressor noise source, mechanical noise is one of compressor Main Noise Sources.
Between mechanical motion pair, friction is that a part is in another part surface relative sliding or rotation.Because part needs to ensure certain fit up gap in assembly process, in gap, be full of lubricant film, so the relative sliding of part is not high with the mechanical noise that rotates generation simultaneously.
In the prior art, compressor air suction valve block, exhaust valve plate, all using high carbon steel or stainless steel as material; Compressor valve seat, is all metallic material, and the noise that valve block impacts valve seat unavoidably becomes Main Noise Sources.As shown in Figures 1 to 4.
At present, the compressor valve plate generally using in compressor industry, is high-carbon valve steels or Martensitic Stain Less Steel; The valve seat that compressor uses, is powder metallurgy, 08AL or cast iron, and rigidity is stronger, valve block is in unlatching and closing course, and because suction, exhaust valve plate have certain rigidity, valve block impacts valve seat, add valve seat itself as a kind of metallic material, the valve block of rigidity knocks the valve seat of rigidity, impacts frequency very high, and energy is also high, and the noise that valve block and valve seat impact also can produce secondary noise in transmittance process, therefore, to impact valve seat noise be one of compressor Main Noise Sources to valve block
Existing piston freezer compressor ubiquity valve block not of uniform size knocks the main mechanical noises such as valve seat high-frequency noise.Meanwhile, in order to take into account reduction compressor noise, the lift of valve metal film is little, and quality is large, and the air resistance loss that overcomes the quality of valve block own is large, and compressor pressure loss is large, and pressure coefficient is low, and gas transmission coefficient is low, and therefore, compressor Energy Efficiency Ratio can not be too high.Therefore there is the hidden danger that noise is large, Energy Efficiency Ratio is low in existing valve metal film and valve plate.
The direction of current Compressor Technology development is to reduce noise, and low noise compressor could be accepted by market and user.
