The utility model is characterized in that a central cooler (1) is mounted between the cylinders (2, 3), the grooves (10, 11) are opened on an external circle surface and two end sides of an inner rotor (6) of the cylinders (2, 3), a shaft sleeve (9) and a sealing ring (8) are mounted outside the rotor shaft (5), and a groove (4) is opened on an internal circle of an suction valve platform (12), which is positioned in the cylinders (2, 3). The utility model has the characteristics of high exhaust pressure, large volume efficiency, small volume and energy ratio and low exhaust temperature. Under the same exhaust pressure and the same driving motor efficiency circumstances, the volume efficiency improves 25 percent, the volume flow increases 20 percent, the volume and energy ratio reduces 20 percent, the exhaust pressure enhances from 0.7MPa to 1.25MPa, and the exhaust temperature does not exceed 200 DEG C.
Description
Technical field:
The utility model relates to a kind of swing compressor, the unlubricated swing compressor of particularly a kind of water-cooled.
Background technique:
That unlubricated swing compressor has is simple in structure, volume is little, in light weight, characteristics such as noise low and vibration is little, and the unlubricated swing compressor of the water-cooled that is applied to produce is a single stage compression, and exhaust pressure is 0.2～0.7MPa, and volume flow is 3～20m
3/ min, the air-cooled unlubricated swing compressor that is applied to produce, exhaust pressure is 0.2～0.3MPa, volume flow is 4.8～9m
3/ min.Therefore at present the swing compressor exists exhaust pressure low, poor performance, and particularly when exhaust pressure during greater than 0.5MPa, volumetric efficiency is low, and power consumpiton is big, volume specific energy height; The delivery temperature height is above 200 ℃.
The model utility content:
Existing swing Compressor Discharge Pressure is low, volumetric efficiency is low, power consumpiton reaches the high deficiency of volume specific energy greatly in order to overcome, the utility model provides a kind of water-cooled unlubricated swing compressor, and this compressor has exhaust pressure height, volumetric efficiency height, the volume specific energy is low and the low characteristics of delivery temperature.
The technological scheme that the utility model adopted is: the unlubricated swing compressor of this water-cooled, comprise crankcase, cylinder and air filter, and between the I and II cylinder, be equipped with interstage cooler, form two stage compression; Place on the cylindrical of cylinder internal rotor and the both sides end face and have groove, rotor shaft is equipped with axle sleeve and seal ring outward; Place in the suction valve platform in the cylinder and have groove on the circle.
Above-mentioned groove respectively is 2; The seal ring inwall is the sawtooth groove.
The beneficial effects of the utility model are: because this compressor has the I and II cylinder to form two stage compression, place cylindrical and lateral grooves that built-in diaphragm seal is arranged on the rotor in the cylinder, the seal ring that axle sleeve that rotor shaft is outer and inwall have the sawtooth groove forms sealing, and the interior round recessed of built-in diaphragm seal is arranged on the suction valve platform.Exhaust pressure is brought up to 1.25MPa by 0.7MPa, improves volumetric efficiency; Reduce power consumpiton, reduce the volume specific energy; Under the situation of same exhaust pressure and identical drive motor power, volumetric efficiency improves 25%, and volume flow increases by 20%, and the volume specific energy reduces by 20%, reduces delivery temperature, and delivery temperatures at different levels are no more than 200 ℃.

Fig. 1 is the utility model schematic representation;
Fig. 2 is the structure sectional view of cylinder 2 among Fig. 1;
Fig. 3 is the left view of Fig. 2 rotor 6.
1-interstage cooler among the figure, 2-secondary cylinder, 3-one-level cylinder, 4-groove, 5-rotor shaft, 6-rotor, 7-cooling water hole, 8-seal ring, 9-axle sleeve, 10-groove, 11-groove, 12-suction valve platform.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in FIG., the unlubricated swing compressor of a kind of water-cooled comprises cylinder (2,3) and rotor 6, because I and II cylinder (3,2) forms two stage compression, pressure ratios at different levels are reduced, improve volumetric coefficient, the one-level volumetric efficiency is improved, increase compressor volume flow; Improve exhaust pressure, the two-stage exhaust pressure can reach 1.25MPa; Between one-level cylinder 3 and secondary cylinder 2, be equipped with interstage cooler 1, the pressurized gas temperature reduced and volume dwindles, thereby reduced the compression work of next stage, reduced delivery temperature; I and II cylinder (3,2) all be equipped with rotor 6 in, have on the rotor 6 two to foreign round, lateral grooves (10,11), cylindrical, lateral grooves (10,11) respectively be equipped with two graphite diaphragm seals in, in rotor 6 swing process, better play the effect of sealing gas and increase exhaust pressure, form the gas leakage trigonum between two end faces, rotor shaft 5 and the cylinder body wall of rotor 6, can dwindle the gas leakage trigonum by outside rotor shaft 5, being equipped with axle sleeve 9, axle sleeve 9 external graphite-seal rings 8 are to reduce the external leakage of gas; And the inwall of seal ring 8 to be sawtooth groove and axle sleeve 9 form sealing, further reduced the external leakage of gas, the center hole of rotor shaft 5 is a cooling water hole 7, communicates cooling down high-temperature gas with cooling water channel on the cylinder (2,3).Two ends in the I and II cylinder (3,2) all are equipped with the suction valve platform 12 that has 2 grooves 4 that structure is identical, vary in size, and groove 4 built-in graphite grazing sheets reduce the leakage of gas.
Because having adopted the two-stage swing compressor of said structure can bring up to exhaust pressure between 0.7～1.25MPa; Improve volumetric efficiency, increase volume flow; Reduce delivery temperature, delivery temperatures at different levels are no more than 200 ℃.Improve the performance of swing compressor by a relatively large margin, enlarged application area.
