Description
Technical Field
The invention relates to the technical field of scroll compressors, in particular to an oil injection cooling structure for a closed type scroll compressor for helium.
Background
The scroll compressor is a compressor with compressible volume comprising one fixed involute scroll and one eccentric orbiting scroll. The gas is sucked into the periphery of the static disc, and is gradually compressed in a plurality of crescent compression cavities formed by the meshing of the dynamic disc and the static disc along with the rotation of the eccentric shaft, and then is continuously discharged from the axial hole of the central part of the static disc.
In the scroll compressor for helium, the heat quantity is large after the helium is compressed, so that the temperature rise, the deformation and the like of scroll parts are easy to occur, and the mechanical performance of the compressor is greatly reduced and even the compressor cannot work normally.
In the prior art, as in the case of the helium hermetic scroll compressor with the patent number of cn201210148686.X, oil injection is performed to two compression chambers by forming an oil injection port at the bottom of a fixed scroll and forming a slot hole shape (i.e., L7 > t) with a length dimension larger than the width dimension of a orbiting scroll at the opening thereof, so as to achieve the cooling purpose. However, this structural design has the following drawbacks: 1. in the moving process of the movable vortex plate, the long hole shape can be spanned on two compression chambers at the same time, the two chambers are mutually communicated to cause air leakage, efficiency loss is caused, cooling oil is unevenly distributed in the two chambers, and therefore the cooling effect of the two chambers is inconsistent; 2. the arrangement of a single oil hole easily causes untimely discharge of cooling oil, and the cooling oil is accumulated in the compression cavity to cause pressure fluctuation in the cavity, so that the compression efficiency is reduced; 3. in the moving process of the movable scroll, only when the movable scroll is positioned at the center of the long hole shape, the long hole shape is consistent with the communication area of the two chambers, and at other moments, the communication area of the two chambers is inconsistent, namely the oil injection quantity is inconsistent, so that the oil injection quantity of the two chambers cannot be accurately controlled; 4. the long hole shape is always communicated with the compression chambers (namely, simultaneously communicated with one compression chamber or communicated with the other compression chamber), and the oil injection process is continuous, so that the oil injection quantity cannot be accurately controlled. For example, a static disc of an oil injection scroll compressor and a scroll compressor with the patent number of CN202310625628.X are provided, and oil injection cooling of two compression chambers is realized by arranging two or more oil injection structures. However, in the structural arrangement, the oil injection process of the two compression chambers is continuous, so that the compression efficiency is affected; the other two oil injection structures share the oil injection channel, so that the oil injection quantity of the two chambers is uncontrollable, the oil injection time can not be accurately controlled according to the compression time of the two compression chambers, and meanwhile, the cooling oil is easily accumulated in the two compression chambers to cause pressure fluctuation. Therefore, how to finely control the oil-injected cooling of helium with a scroll compressor to improve the cooling capacity while ensuring the stability of helium compression is a problem to be considered by those skilled in the art.

Detailed Description
The following describes the present invention in further detail with reference to specific examples:
as shown in fig. 1 to 5, an oil injection cooling structure for a hermetic scroll compressor for helium includes an orbiting scroll 1 and a fixed scroll 2, and a first compression chamber 3 and a second compression chamber 4 formed by the orbiting scroll 1 and the fixed scroll 2 together; and is provided with an oiling mechanism 5 and a medium pressure cavity 6, wherein the oiling mechanism 5 is connected with an oil injection assembly 21 on the fixed scroll 2. As shown in fig. 5, the arrow in the figure is the flowing direction of compressed gas, when the air compressor works, the fixed scroll 2 is static, the movable scroll 1 integrally translates under the drive of the driving device 7 such as a motor, the center of the base circle of the movable scroll 1 rotates 360 degrees relative to the center of the base circle of the fixed scroll 2, the movable spiral teeth 12 and the fixed spiral teeth 22 are formed in the rotating process to form a first compression cavity 3 and a second compression cavity 4, the compression of gas is realized, finally, the compressed gas is discharged through the air outlet 24 in the middle of the fixed disk bottom plate 23 of the fixed scroll 2, and the throttling gas is discharged into the middle pressure cavity 6 through the throttling channel 13 arranged on the movable scroll 1. During the process of compressing gas, a large amount of heat is generated, cooling oil needs to be adopted for cooling, the cooling oil enters the first compression cavity 3 and the second compression cavity 4 respectively through the oil injection assembly 21, passes through the first oil outlet 111 and the second oil outlet 112 of the oil outlet assembly 11 respectively after cooling, and finally is discharged to the medium pressure cavity 6 through an oil outlet channel (not shown in the figure) to form an oil communication loop. The arrangement of the two independent oil outlets also ensures the timely discharge of the cooling oil in the two compression cavities and avoids accumulation in the cavities.
The oil spray cooling structure specifically comprises:
as shown in fig. 2 to 3, the oil injection assembly 21 includes an oil feed passage provided inside the fixed scroll 2. The oil inlet passage comprises a first vertical hole 211 connected with the oil injection mechanism 5, a first transverse hole 213 with two ends respectively connected with the first vertical hole 211 and the first oil injection hole 212, and a second transverse hole 215 with two ends respectively connected with the first vertical hole 211 and the second oil injection hole 214. The first oil jet 212 and the second oil jet 214 are connected to the first compression chamber 3 and the second compression chamber 4, respectively.
In the present embodiment, the first oil jet 212 and the second oil jet 214 are provided on the stationary plate bottom plate 23 and are not coincident with the stationary plate teeth 22. That is, the stationary plate teeth 22 form a rotating and involute groove in the stationary plate bottom plate 23, in which the first and second oil jet holes 212 and 214 are disposed; in addition, the diameters of the first oil spray hole 212 and the second oil spray hole 214 are smaller than the width of the movable spiral teeth 12, so that the end parts of the movable spiral teeth 12 can be effectively overlapped with the first oil spray hole 212 and the second oil spray hole 214 in the movement process of the movable vortex plate 1, and oil spraying is stopped when the first oil spray hole and the second oil spray hole are completely overlapped; and oil injection is carried out when the first compression cavity 3 and the second compression cavity 4 are not overlapped or partially overlapped, so that intermittent oil injection is realized.
During the movement of the orbiting scroll 1, the gas in each compression chamber is always in dynamic fluctuation, i.e., in different stages in one cycle of the orbiting scroll 1, from the suction to the compression to the discharge, so that the control of the injection timing of the cooling oil is important, and the cooling effect is poor due to the early or late injection.
Fig. 6-1 to 6-5 are schematic diagrams showing the relationship between the first oil injection hole 212 and the first compression chamber 3 when the orbiting scroll 1 translates relative to the fixed scroll 2 in one compression cycle. The tooth-shaped phase difference of the movable vortex plate 1 and the fixed vortex plate 2 is 180 degrees, the movable vortex plate 1 integrally translates, and the base circle center of the movable vortex plate 1 rotates 360 degrees around the base circle center of the fixed vortex plate 2. For convenience of explanation, the first oil injection hole 212 and the first compression chamber 3 are exemplified. As shown in fig. 6-1, the end face of the moving coil tooth 12 completely covers the first oil jet 212, and the first oil jet 212 is about to be opened, and at this time, the first oil jet 212 does not spray oil; as shown in fig. 6-2 to 6-4, the movable scroll 1 continues to move, the end face of the movable spiral teeth 12 gradually breaks away from the first oil injection hole 212, and the opening degree of the first oil injection hole 212 gradually increases; until the end face of the moving coil tooth 12 is completely separated from the first oil injection hole 212, the first oil injection hole 212 is completely opened; then the moving coil teeth 12 approach to and gradually coincide with the first oil spray holes 212, and in the process, the first oil spray holes 212 spray oil to the first compression cavity 3; as shown in fig. 6-5, the moving coil teeth 12 continue to move until the end surfaces of the moving coil teeth 12 completely cover the first oil jet 212, at which time the first oil jet 212 does not spray oil. By this circulation, intermittent oil injection of the first compression chamber 3 is achieved. Similarly, the second oil injection hole 214 can also realize intermittent oil injection to the second compression chamber 4, which is not described herein.
In addition, in the scroll compressor, the offset molded line is designed, the first compression chamber 3 and the second compression chamber 4 formed after the movable scroll 1 and the fixed scroll 2 are meshed with each other are not necessarily symmetrical, the volumes are not necessarily the same, and the initial air inlet time of the two compression chambers is different, so that the cooling effect is further optimized, the cooling effect is consistent when the two compression chambers discharge air, the optimal cooling effect is achieved, and the relative positions and the opening sizes of the two oil injection ports in the respective compression chambers can be independently designed. For example, taking the first oil injection hole 212 and the first compression chamber 3 as examples, if the first oil injection hole 212 is arranged near the air inlet of helium, the oil injection time is short, the expected oil injection amount is not reached, and the cooling effect is poor; and if the oil injection starts before the first compression chamber 3 is charged and a closed chamber is formed, the volume of the first compression chamber 3 is occupied, so that the air intake is reduced, and the compression efficiency is low. Similarly, if the first oil spraying hole 212 is disposed near the air outlet 24, the oil spraying may be not timely, and the time is short, and the expected cooling effect may not be achieved.
The sizes of the apertures of the first and second fuel injection holes 212 and 214 may also be adjusted to control the amount of fuel injected. In other embodiments, the first oil spraying hole 212 and the second oil spraying hole 214 may be provided in other shapes such as long bar, so as to more accurately control the opening and closing time of the two oil spraying holes, and more accurately control the oil spraying time or the non-oil spraying time. The cooling efficiency is improved and the compression efficiency of the compressor is further improved.
According to the design of the oil injection cooling structure, taking the first oil injection hole 212 and the first compression chamber 3 as examples, the usage of the compressor when the first oil injection hole 212 is designed with different apertures and different positions is further analyzed:
taking the state where the first fuel injection hole 212 is about to be fully opened as an example. Setting the injection pressure of the first injection hole 212 to P Oil 1 ，P Oil 1 =2.1 Mpa. At this time, the first oil injection hole 212 is communicated with the first compression chamber 3 to form a pressure P Cavity 1 ，P Cavity 1 The value is determined by the position of the first fuel injection hole 212. The rotation angle θ=0 of the orbiting scroll 1 immediately before the full opening of the first oil injection hole 212 is set. At the moment, the first pressure can be obtained according to the design of the vortex molded lineThe volume of the compression chamber 3 is reduced, and the pressure P of the first compression chamber 3 can be calculated Cavity 1 Wherein the calculation of the compression chamber volume and pressure is prior art and will not be described in detail herein. In this specific position, the relationship between the pressure and the rotation angle of the first compression chamber 3 in which the first oil jet 212 is located is shown in fig. 7.
As can be seen from the graph pressure curve, the injection pressure P is calculated at the first injection hole 212 Oil 1 Smaller than the first compression chamber 3P Cavity 1 And when the oil is not sprayed, the oil is not sprayed. At the injection pressure P of the first injection hole 212 Oil 1 Greater than the first compression chamber 3 pressure P Cavity 1 The desired injection quantity can be obtained from the respective states of the opening area of the first injection hole 212. After the first oil jet 212 is set at a specific position, the oil jet passing through the first oil jet 212 is compared with the expected oil jet as shown in fig. 8, wherein the oil jet is determined by the aperture of the first oil jet 212, so that the oil jet is far greater than the expected oil jet when the aperture of the first oil jet 212 is phi 2.5mm, resulting in efficiency loss; when the aperture of the first oil spraying hole 212 is phi 2.0mm, the actual oil spraying amount can be approximated to the theoretically required oil spraying amount, so as to achieve the purpose of optimizing the performance of the compressor. The desired injection quantity is obtained by the difference of the enthalpy corresponding to the suction pressure, suction temperature, discharge pressure and desired maximum discharge temperature of compressed helium gas and the injection temperature and physical properties of the cooling oil used when reaching a certain cooling effect or decreasing to a certain set temperature, which is the prior art and is not described in detail.
Similarly, as shown in fig. 9, the effect of different positions on the compressor is shown when the aperture of the first oil jet 212 is 2.5 mm. The first fuel injector 212 is shown positioned with a line spread angle of 700 degrees and a line spread angle of 730 degrees. In the figure, compared with the molded line expansion angle of 730 degrees, the molded line expansion angle is closer to the expected oil injection amount when 700 degrees, and the optimal purpose of the compressor can be achieved.
