Problems solved by technology

[0003] In this document there is the problem of exciting the working medium compressed by the screw rotor to vibrations with a fundamental frequency dependent on the rotational speed of the screw rotor, which at least leads to a noise load, but possibly in the case of stochastic resonances for later use The compressed working medium creates mechanical problems in the piping system and can even lead to mechanical damage in the piping system

Embodiment Construction

[0051] The screw compressor according to the present invention has figure 1 The embodiment shown in includes a housing, generally designated 10, consisting of an intermediate portion 12, an end portion 14 on the motor side, and an end portion 16 on the pressurized side.

[0052] For example, the motor-side end part 14 is formed by a first housing sleeve 18 formed in one piece on the central part 12 , which is closed by a first housing cover 20 which is releasably connected to the first housing cover via a flange connection 22 . The shell sleeve 18 is connected.

[0053] Arranged in the motor-side end part 14 is a drive motor, designated as a whole with 30 , which is designed, for example, as an electric motor, which has a stator 32 held in the first housing sleeve 18 , which surrounds the rotor 34 , wherein The rotor 34 is mounted on a drive shaft generally indicated at 36 .

[0054]In the intermediate portion 12 of the housing 10 is provided a compressor screw casing genera...

Abstract

In order to avoid pulsations in a screw compressor comprising an outer housing, a compressor screw housing which is arranged in the outer housing and in which rotor bores for screw rotors are arranged, a drive arranged in the outer housing on one side of the compressor screw housing and a bearing housing arranged in the outer housing on a side of the compressor screw housing located opposite the drive, it is suggested that an acoustic wave damping device having the compressed working medium flowing through it be arranged within the outer housing.

Description

technical field [0001] The invention relates to a screw compressor, which comprises a casing; a compressor screw casing arranged in the casing, a rotor hole for a screw rotor is arranged in the compressor screw casing; in the casing, one side of the compressor screw casing drive means provided on; and a bearing housing provided in the housing on the opposite side of the drive means of the compressor screw casing. Background technique [0002] Such a screw compressor is known from DE 198 45 933.9-15. [0003] The problem in this document is that the working medium compressed by the screw rotor is excited to vibrate by a fundamental frequency which is dependent on the rotational speed of the screw rotor, which fundamental frequency at least results in a noise load, but which may be used in the following applications in the case of stochastic resonances. Mechanical problems arise in the piping system of the compressed working medium and can even lead to mechanical damage in th...
