Embodiment Construction

[0025] As shown in the figure, the present invention relates to a fluid conducting duct with a special configuration that allows to solve the noise and / or resonance generated by the discharge duct in a reciprocating compressor operating at a high angular velocity regime (above 4500 rpm) Or the problem of the rupture of the pipeline, it is economically feasible and technically efficient.

[0026] Such as figure 1 As shown in , the peak of the noise level produced by a reciprocating compressor is accurately characterized at speeds above 4500rpm, making a configuration for this problem highly essential.

[0027] Accordingly, the fluid conducting conduit of the present invention is preferably suitable for use in a discharge system of a reciprocating compressor 1 comprising a first conduit portion 3 , a first expansion chamber 4 , a second conduit portion 5 and a second expansion chamber 6 . Said first duct portion 3 connects the discharge chamber 2 of the compressor 1 to the firs...

Abstract

The present invention relates to a fluid-conducting pipe of a reciprocating compressor made of polymeric material, and further including at least one vibrational energy dissipation element, basically,aiming at solving the problem of noise and the breakage of the pipe deriving from the resonance of the discharge piping in reciprocating compressors operating at high angular speed regimes.

Description

technical field [0001] This invention relates to fluid conducting conduits for reciprocating compressor discharge systems. The ducts are configured to reduce noise generated in high angular velocity reciprocating compressors. Background technique [0002] As is well known in the prior art, reciprocating compressors of refrigeration equipment comprise a refrigerant discharge system which, in addition to the outlet duct of the compressor, usually includes an acoustic filter consisting of an expansion chamber and an interconnected pipeline composition. [0003] It is also well known that reciprocating compressors operate at different angular velocities depending eg on the volume of the compartment to be cooled and the required cooling temperature. [0004] For reciprocating compressors operating at high angular velocities, the operating frequency of the compressor itself may coincide with the natural frequency of its discharge piping. This coincidence or resonance causes an ...
