Problems solved by technology

In this conventional example, as in the above-mentioned conventional example, the noise reduction effect on the pulsation of the discharge pressure in a certain frequency band is exerted, but if the rotational speed of the compressor is changed, the frequency of the noise changes, and it cannot be achieved in all operating conditions. get low noise

Embodiment Construction

[0026] Next, refer to the attached figure 1 A liquid-cooled screw compressor according to Embodiment 1 of the present invention will be described. figure 1 It is a system diagram for explaining the low-noise liquid-cooled compressor according to Embodiment 1 of the present invention.

[0027] Regarding the low-noise liquid-cooled compressor according to Embodiment 1 of the present invention, a low-noise oil-cooled screw compressor using cooling oil as a coolant will be described as a specific example. This low-noise oil-cooled screw compressor includes a compressor body 1 in which a pair of male and female screw rotors 2a, 2b are meshed and rotatably housed in a rotor chamber 4 formed inside a rotor casing 3. And constituted. The suction flow path 5 is connected to the suction port 1 a of the compressor body 1 , while one end side of the discharge flow path 6 is connected to the discharge port 1 b of the compressor body 1 . Furthermore, only one of the pair of male and fe...

Abstract

A low-noise liquid-cooled compressor of the invention has a liquid-cooled screw compressor with a pair of screw rotors which are meshed. The inhalation to the above-mentioned screw in the rotor supply of inhalation gas flow on the road I set up oil from the oil to the above I inhaled into the liquid flow path. According to this structure, even if the compressor and the speed of change in the frequency of occurrence of the noise changes to the functioning of the state in a variety of low-noise results obtained, mainly through the compressor to reduce the inhalation flow path and out to the external noise amplitude, in particular to reduce the inhalation side of the compressor body pulse amplitude in order to suppress noise.

Description

technical field [0001] The present invention relates to a low-noise liquid-cooled compressor for suppressing noise emitted to the outside mainly through the suction flow path of the compressor in a liquid-cooled screw compressor having a pair of male and female screw rotors meshing with each other. The amplitude, especially the pulse amplitude on the suction side of the compressor body is reduced to suppress the noise value. Background technique [0002] The temperature of the screw rotor (hereinafter also referred to as the rotor) of the screw compressor rises as the fluid is compressed. Therefore, a cooling mechanism for cooling the screw rotor is required. As such a cooling mechanism, conventionally, generally, an external cooling device is used to supply cooling air, cooling liquid, or the like. [0003] Therefore, first of all, for the general cooling mechanism of an oil-cooled screw compressor using cooling oil (hereinafter also simply referred to as oil) as the abov...
