Abstract
The utility model relates to a screw compressor, and in particular discloses an oil separation system for a vertical screw compressor. The oil separation system for the vertical screw compressor comprises a screw compressor body, and a motor, a male screw motor and a female screw motor which are arranged on the screw compressor body; and the motor comprises a motor stator and a motor rotor. The oil separation system for the vertical screw compressor is characterized in that an oil baffle is arranged on an airflow channel on the upper part of the motor; a secondary precision oil filter plate is arranged on the upper part of the oil baffle; an annular primary oil filter device is also arranged on the periphery of the motor stator; the secondary precision oil filter plate is a stainless steel mesh plate; and the oil filter material of the primary oil filter device is a high polymer material. Compared with the prior art, the oil separation system for the vertical screw compressor has the advantage that the oil separation effect is improved obviously; and pure high-quality compressed air can be output, so that the heat exchange efficiency and the service life of a heat exchange unit are improved.
Description
Technical field
The utility model relates to a kind of helical-lobe compressor, and the oil that relates in particular to a kind of vertical screw compressor separates system.
Background technique
It is that oil-containing pressurized air that main frame is produced is through mechanical separation or filtration that the oil of compressor separates function; Mist of oil in the gas is tackled or polymerization formation oil droplet; Turn back to the lubrication system of compressor again through drainback passage, can make compressor discharge purer, high-quality pressurized gas.Remove solid-state dust, oil gas particle and liquid in the pressurized gas through oil separating device in other words.Oil separating device in the vertical compressor of existing technology normally is provided with the oil content baffle plate on air-flow path; Be provided with the high precision oil filter plate on the top of oil content baffle plate; Pressurized gas is discharged through behind bump on the oil content baffle plate, filtering through the high precision oil filter plate again, though this oil separating structure is simple, because the integral filter area is little, gas flow rate is fast; Therefore oil separates weak effect, and the pressurized gas that oil content is big is known from experience heat exchange efficiency and the operating life that reduces back level heat exchanger.
The model utility content
The utility model provides a kind of oil of vertical screw compressor to separate system to the deficiency of above-mentioned oil separating device.It can make oil gas separation significantly improve.
The technological scheme that the utility model solves the problems of the technologies described above is following: a kind of oil of vertical screw compressor separates system; Comprise compressor block, be installed in motor and negative and positive screw rotor on the said body; Said motor comprises motor stator and rotor, it is characterized in that, on the air-flow path on said motor top, is provided with the oil content baffle plate; Be provided with secondary high precision oil filter plate on the top of said oil content baffle plate, also be provided with the once oily filter device of annular in the periphery of said motor stator.
Said secondary high precision oil filter plate is the stainless steel web plate.
The oily filtering material of said once oily filter device is a macromolecular material.
The beneficial effect of the utility model is: get into the once oily filter device of annular through air-flow path behind the pressurized gas process oil content baffle plate and filter; Gas after the filtration filters through secondary high precision oil filter plate and discharges; Because the filter area of annular once oily filter device is much larger than the filter area of secondary high precision oil filter plate, therefore oil separation effect can obviously improve., the filtrating equipment oil content of existing technology about 96%, can reach 99% as going out rate and the filtration system oil content of the utility model goes out rate.Purer, high-quality pressurized gas, and then improved the heat exchange efficiency and the operating life of heat exchange unit.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure, 1, secondary high precision oil filter plate; 2, oil content baffle plate; 3, the once oily filter device of annular; 4, overdraught passage; 5, motor stator; 6, rotor; 7, positive screw rotor; 8, female screw rotor; 9, body; 10, downstream passage; 11, relief opening.
Embodiment
Below in conjunction with accompanying drawing the principle and the characteristic of the utility model are described, institute gives an actual example and only is used to explain the utility model, is not the scope that is used to limit the utility model.
As shown in Figure 1; A kind of oil of vertical screw compressor separates system; Comprise helical-lobe compressor body 9, be installed in motor and female screw rotor 8, positive screw rotor 7 on the said body 9, said motor comprises motor stator 5 and rotor 6, on the air-flow path on said motor top, is provided with oil content baffle plate 2; Be provided with secondary high precision oil filter plate 1 on the top of said oil content baffle plate 2, also be provided with the once oily filter device 3 of annular in the periphery of said motor stator 5.
Said secondary high precision oil filter plate 1 is the stainless steel web plate.
The oily filtering material of said once oily filter device 3 is a macromolecular material.
The working principle of the utility model is: the gas through the screw rotor compression gets into motor internal and outside cooling air flow passage through the downstream path 10; Gas is sprayed onto on the oil content baffle plate 2 from cooling air flow passage then; Get into the once oily filter device 3 of annulars through overdraught passage 4 again and filter, oil content baffle plate 2 is assembled the part mist of oil and compile and forms the oil droplet Huis oil groove that falls; Be ejected on the inwall that machine casing is a pressurized container by once oily filter device 3 filtrations of annular, mist of oil is collected through this inwall viscous once more, and then gas gets into secondary high precision oil filter plate 1 and filters the back from relief opening 11 discharges.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
