Abstract
The invention relates to an F25B refrigeration machine, a refrigeration device or system class in international patent classification (IPC) through searching, and particularly belongs to a low-noise lead compressor exhaust end base. According to the technical scheme provided by the invention, the low-noise lead compressor exhaust end base comprises an exhaust end base body (4), a female rotor hole (1), a male rotor hole (6) and an exhaust hole (2) positioned below the female rotor hole (1) and the male rotor hole (6). The low-noise lead compressor exhaust end base is characterized in that the surface of the exhaust hole (2) comprises corrugated step surfaces (3) and a smooth surface (5), the corrugated step surfaces (3) are formed by a plurality of grooves (31), and the center distance between upper edges (32) of the corrugated step surface and the corresponding female rotor hole (1) or male rotor hole (6) is less than that between lower end edges (33) of the corrugated step surface and the corresponding female rotor hole (1) or male rotor hole (6). The low-noise lead compressor exhaust end base achieves the purpose of effectively reducing exhaust noise of a screw compressor.
Description
Technical field
The present invention relates to F25B refrigerator on International Classification of Patents (IPC) through retrieval, and chiller plant or system's classification especially belong to low noise helical-lobe compressor exhausting end base.
Background technique
Helical-lobe compressor is a kind of positive displacement compressor of forcing gas transmission, and mainly engagement and the high-speed rotary by a pair of negative and positive rotor transfers compression and the conveying that realizes gas.Compressor is in the process of operation, and the engagement of rotor and the suction and discharge of compressor cycle all can produce noise, and in the situation that overcompression and under-voltage contracting occur, all gas expansion and backflow phenomenon will occur, with the generation of aggravation noise, these noises are all generally continuous high frequencies.And the position of the relief opening of helical-lobe compressor and shape play a crucial role to the exhaust sound size of helical-lobe compressor, because the design to exhaust outlet of compressor does not in the past take into full account the problems referred to above, make helical-lobe compressor produce very large noise in running, environment is caused very large noise pollution.
Summary of the invention
The object of the present invention is to provide a kind of low noise helical-lobe compressor exhausting end base, thereby reach the purpose of effective reduction helical-lobe compressor exhaust sound.
The technical solution used in the present invention is: it comprises exhaust end pedestal (4), female rotor hole (1), male rotor hole (6), and the exhaust port (2) that is positioned at female rotor hole (1) and below, male rotor hole (6), it is characterized in that: the surface of described exhaust port (2) is comprised of corrugated ledge surface (3) and smooth surface (5); Described corrugated ledge surface (3) is comprised of several grooves (31), and the centre distance in corrugated ledge surface top edge (32) and corresponding female rotor hole (1) or male rotor hole (6) is less than the centre distance of corrugated ledge surface lower limb (33) with corresponding female rotor hole (1) or male rotor hole (6).
Beneficial effect of the present invention is: compared with prior art, offer corrugated step on exhaust port due to the present invention, when gas passes through exhaust port, air-flow can change, refraction can occur and mutually interfere in the high frequency waves in sound wave, weaken sound wave, reduce noise, thereby reach the purpose of effective reduction helical-lobe compressor exhaust sound.
