Description
(1) technical field:
The utility model relates to a kind of scroll compressor, especially a kind of scroll compressor with resistance to compression and sealing structure, and its resistance to compression and sealing structure can improve the sealing of high-pressure chamber, avoid welding slag to enter cavity, and improve the Energy Efficiency Ratio of scroll.
(2) background technique:
Scroll compressor is revolution suction and the pressurized gas that utilizes scroll, and the compressed gas of its discharge enters the hyperbaric chamber in the compressor, can discharge by relief opening then.Fig. 1 is the vertical section figure of existing a kind of compressor.As shown in the figure, existing scroll compressor mainly comprises: a housing A who has intakeport 1 and relief opening 2, and comprising loam cake 3, lower cover 4 and middle case 5; A fixed scroll 6 is fixed together with loam cake 3; A moving scroll 7 forms pressing chamber with fixed scroll 6 combinations; A support 8 is used for supporting moving scroll 7; 9, one transmission shafts 10 of motor that comprise stator and rotor are used for transmitting rotary power, cause moving scroll 7 thereupon translation and pressurized gas; An exhaust valve plate 11 prevents that gas from refluxing from hyperbaric chamber IB.Its working procedure is: gas enters from intakeport 1, after motor 9 starts, moving scroll 7 can be carried out translation with the rotation of transmission shaft 10, thereby its vortex filament structure forms the gas compression cavity with the vortex filament structure of fixed scroll 6, and generation high pressure-temperature gas, this high temperature and high pressure gas can enter hyperbaric chamber IB with moving of scroll, and exhaust valve plate 11 can stop the backflow of high pressure intracavity gas; The high pressure intracavity gas is discharged by relief opening 2.This process circulates repeatedly, can constantly produce pressurized gas.Be the predominating path of gas flow among Fig. 1 shown in the arrow.
But in the working procedure of above-mentioned compressor, because fixed scroll 6 directly contacts hyperbaric chamber IB, fixed scroll 6 is subjected to the influence of high-pressure, will certainly make the pressure between scroll 7 and the fixed scroll 6 increase (seeing the direction of arrow in Fig. 2 hyperbaric chamber IB), the clearance C (see figure 2) is reduced and influence the motion of scroll, thereby reduce its task performance, finally reduce the Energy Efficiency Ratio of whole compressor.
For the compressor series products, the size of the gas pressure of discharging directly influences its task performance in addition, and it is crucial therefore keeping the force value in the hyperbaric chamber IB.But, because the mode with interference fit between the fixed scroll 6 of this kind compressor and the loam cake 3 links to each other, institute thinks and prevents that gas from revealing at connecting place, machining accuracy and assembling work required precision to the cooperation place are very high, therefore, be difficult to guarantee the sealing of cooperation place, so gas is easy to leak to from here in the low-pressure cavity D in the hyperbaric chamber IB, thereby the gas that is pressed in the hyperbaric chamber IB is discharged with 100% pressure, and influence the working efficiency of compressor.
Except that above 2, the motion of scroll is the key of scroll compressor, so moving scroll 7 must fit tightly and guarantee good lubricating with the scroll portion office of fixed scroll 6, can not have any foreign material to enter therebetween.But the loam cake 3 of above-mentioned compressor and middle case 5 are connected with welding manner, and there is obvious gaps E (see figure 2) in the lap-joint between them, and this just provides possibility (seeing the direction of arrow in Fig. 2 low-pressure cavity D) for welding slag enters scroll.In a single day welding slag enters in the scroll, or attached to the vortex part, not only the running noises of compressor can aggravate, and can have a strong impact on the compression efficiency of scroll, even causes vortex position fracture and cause compressor to be scrapped.
(3) model utility content:
The purpose of this utility model provides a kind of scroll compressor with resistance to compression and sealing structure, and its resistance to compression and sealing structure can prevent quiet spiral dish pressurized, prevent that welding slag from entering scroll, and guarantees to make pressurized gas to discharge with the pressure near 100%.
The technical solution of the utility model is: a kind of scroll compressor with resistance to compression and sealing structure, it comprises the loam cake that has relief opening, lower cover has the middle case of intakeport, a fixed scroll, a moving scroll, a support, a motor that comprises stator and rotor, a transmission shaft and an exhaust valve plate, it is characterized in that an inner cap is arranged between said loam cake and middle case, inner cap is with loam cake and middle case respectively and is connected.
Above-mentioned said inner cap is enclosed within on the middle case and is connected in the interference mode for the inner cap periphery stretches out middle case with being connected of loam cake and middle case respectively, covers in the interference mode in loam cake is enclosed within to be connected.
Open a sulculus on the above-mentioned said fixed scroll, in put the obstruct packing ring.
Superiority of the present utility model is: 1, cooperate in the interference mode between inner cap and the middle case, just avoided welding slag to enter cavity and scroll when welding like this; 2, being connected in the interference mode of inner cap and loam cake avoided the leakage of gas in the hyperbaric chamber IIF, thereby the gas in the hyperbaric chamber II can be discharged compressor with the pressure near 100%; 3, intercept packing ring and have elasticity, and seal is fine, guaranteed that compressed gas enters hyperbaric chamber IIF smoothly and can not flow out along direction as shown, so the fixed scroll pressure is very little, thereby can not influences the sport efficiency of scroll; 4, the working efficiency with scroll compressor of resistance to compression and sealing structure can improve greatly, and can energy saving.
