[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0054] Reference Figure 1 , Figure 1 A schematic diagram of the structure of a device for determining compressor scroll assembly parameters in a hardware operating environment according to an embodiment of the present invention.

The memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0056] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation on the compressor scroll assembly parameter determination device, and may include more or less components than those shown in the figure, or combine certain components, or arrange the components differently.

[0057] like Figure 1 As shown, the memory 1005 as a storage medium may include an operating system, a network communication module, a user interface module, and a compressor scroll assembly parameter determination program.

[0058] exist Figure 1 In the compressor scroll assembly parameter determination device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the compressor scroll assembly parameter determination device of the present invention can be set in the compressor scroll assembly parameter determination device, and the compressor scroll assembly parameter determination device calls the compressor scroll assembly parameter determination program stored in the memory 1005 through the processor 1001, and executes the compressor scroll assembly parameter determination method provided by the embodiment of the present invention.

[0059] The embodiment of the present invention provides a method for determining the assembly parameters of a compressor scroll plate, referring to Figure 2 , Figure 2 It is a schematic flow chart of the first embodiment of the method for determining compressor scroll assembly parameters of the present invention.

[0060] In this embodiment, the compressor scroll assembly parameter determination method is applied to a scroll compressor, which includes a movable scroll and a fixed scroll. The method includes the following steps:

[0061] Step S10: when assembling the orbiting scroll and the fixed scroll of the compressor, obtaining the required dimensions of the orbiting scroll and the fixed scroll.

[0062] It should be noted that this solution is applied to a scroll compressor. The structural diagram of the scroll compressor is shown in FIG. Figure 3 As shown, Figure 3This is a schematic diagram of the structure of a scroll compressor. The scroll compressor includes a moving scroll and a fixed scroll, and the gaps A1, A2, B1, and B2 between the moving and fixed scrolls. The working principle of the scroll compressor is as follows: the refrigerant from the low-pressure pipeline enters the high-pressure pressure chamber, and the moving scroll rotates to compress the refrigerant. The high-pressure pressure chamber plays a role in compressing the refrigerant; the fixed scroll is fixed, and the moving scroll rotates to compress the refrigerant in the high-pressure pressure chamber, and the low-pressure refrigerant is converted into a high-pressure refrigerant through this structural system. However, when the compressor speed is low and the refrigerant pressure is low, the pressure in the pressure chamber is insufficient, resulting in a smaller gap between the moving and fixed scrolls than when the compressor speed is high and the pressure in the pressure chamber is high. When the gap is small to a certain threshold, the gap is zero, that is, the moving and fixed disks collide, resulting in abnormal noise. Therefore, reasonable moving and fixed disk assembly parameters are needed to solve the problem of uneven gaps, thereby avoiding the problem of impact noise in scenarios with low refrigerant pressure.

[0063] In a specific implementation, when it is necessary to assemble the dimensions of the movable scroll and the stationary scroll of the compressor, the required dimensions of the movable scroll and the stationary scroll can be obtained. The required dimensions of the movable scroll and the stationary scroll are standard dimensions of the movable and stationary scrolls, and the standard dimensions of the movable and stationary scrolls can be obtained through the installation manual, operation manual and technical specification sheet.

[0064] Step S20: querying a target orbiting and stationary scroll matching size matrix table based on the orbiting scroll required size and the stationary scroll required size to obtain an orbiting scroll target size and a stationary scroll target size.

[0065] In a specific implementation, the target moving and stationary disk matching size matrix table includes appropriate moving and stationary disk matching sizes, for example, the moving scroll size is 1, and the stationary scroll size is 4. The moving scroll size of 1 and the stationary scroll size of 4 can ensure that the moving and stationary disk assembly gap is appropriate, so the compressor will not have abnormal noise.

[0066] In actual production, there may be factors such as consistency of manufacturing molds, periodic wear of machining tools, and accuracy of inspection fixtures, which may lead to deviations between the required dimensions of the movable scroll and the required dimensions of the stationary scroll. Therefore, the target dimensions of the movable scroll and the stationary scroll taking into account the deviations can be obtained based on the target movable and stationary disk matching dimension matrix table.

[0067] Step S30: obtaining compressor scroll assembly parameters according to the orbiting scroll target size and the fixed scroll target size.

[0068] In a specific implementation, the target size of the orbiting scroll and the target size of the stationary scroll are used as assembly parameters of the compressor scroll, and the compressor is assembled according to the assembly parameters, thereby solving the problem of abnormal noise at low speed of the compressor through reasonable size matching.

[0069] The compressor scroll assembly parameter determination method of the present embodiment is applied to a scroll compressor, and the scroll compressor includes a movable scroll and a stationary scroll. When assembling the movable scroll and the stationary scroll of the compressor, the required size of the movable scroll and the required size of the stationary scroll are obtained; based on the required size of the movable scroll and the required size of the stationary scroll, a target movable and stationary disk matching size matrix table is queried to obtain the target size of the movable scroll and the target size of the stationary scroll; the compressor scroll assembly parameters are obtained according to the target size of the movable scroll and the target size of the stationary scroll, and the compressor scroll assembly parameters can be obtained quickly and accurately. Reasonable assembly parameter matching can solve the abnormal noise of the compressor at low speed and reduce the scrap rate of parts.

[0070] refer to Figure 4 , Figure 4 It is a schematic flow chart of the second embodiment of the method for determining compressor scroll assembly parameters of the present invention.

[0071] Based on the first embodiment described above, step S20 of the compressor scroll assembly parameter determination method of this embodiment specifically includes:

[0072] Step S201: obtaining a first orbiting scroll required size and a second orbiting scroll required size based on the orbiting scroll required size.

[0073] It should be understood that the movable scroll has an axial dimension and a radial dimension when installed. Therefore, the first movable scroll required dimension and the second movable scroll required dimension can be obtained by the movable scroll required dimension. The first movable scroll required dimension is the radial dimension of the device in the movable scroll. Figure 3 As shown, the required size of the first movable scroll is Figure 3 D in the figure is the required size of the second movable scroll, which is the axial size of the device in the movable scroll. Figure 3 F in.

[0074] Step S202: obtaining a first required size of a fixed scroll and a second required size of a fixed scroll based on the required size of the fixed scroll.

[0075] It should be understood that the fixed scroll disk has axial dimensions and radial dimensions when installed, so the first fixed scroll disk required dimensions and the second fixed scroll disk required dimensions can be obtained by the fixed scroll disk required dimensions. The first fixed scroll disk required dimensions are the axial dimensions of the device in the fixed scroll disk required dimensions, that is, Figure 3 E in the figure, the required size of the second fixed scroll disk is the radial size of the device in the required size of the fixed scroll disk, that is, Figure 3 C in.

[0076] Step S203: query the stationary scroll matching size interval in the target movable and stationary scroll matching size matrix table through the first stationary scroll required size and the second stationary scroll required size, and obtain the first stationary scroll target size, the second stationary scroll target size and the movable scroll matching size interval corresponding to the stationary scroll required size.

[0077] In a specific implementation, the target moving and stationary disk matching size matrix table includes a plurality of moving scroll matching size intervals and a plurality of stationary scroll matching size intervals, as shown in Table 1. Table 1 is the target moving and stationary disk matching size matrix table.

[0078] Table 1

[0079]

[0080] μ1, μ2, μ…, μn are the required dimensions of a certain size of the moving disk or the static disk, that is, the threshold value of a certain size.

[0081] In a specific implementation, the corresponding stationary scroll matching size interval can be queried in Table 1 through the required size of the first stationary scroll and the required size of the second stationary scroll. For example, μ1=5, μ2=10, μn=20, the required size of the second stationary scroll is 5, and the required size of the first stationary scroll is 23. Then, the first stationary scroll target size and the second stationary scroll target size can be obtained in Table 1, which are located in the first row of Table 1, and the movable scroll matching size interval corresponding to the required size of the stationary scroll can be obtained, that is, the movable scroll matching size interval corresponding to the first row in Table 1.

[0082] Step S204: matching a first orbiting scroll target size and a second orbiting scroll target size in the orbiting scroll matching size interval according to the first orbiting scroll required size and the second orbiting scroll required size.

[0083] It should be noted that the required size of the first movable scroll and the required size of the second movable scroll can be queried in the first row of Table 1. For example, if the required size of the first movable scroll is 20 and the required size of the second fixed scroll is 18, then the target size of the first movable scroll and the target size of the second movable scroll are determined to be located in the first row and fourth column of Table 1, thereby determining the target size of the first movable scroll and the target size of the second movable scroll.

[0084] Step S205: obtaining a fixed scroll target size through the first fixed scroll target size and the second fixed scroll target size.

[0085] Step S206: obtaining a target size of an orbiting scroll according to the first orbiting scroll target size and the second orbiting scroll target size.

[0086] It can be understood that the target size of the fixed scroll can be obtained by the first fixed scroll target size and the second fixed scroll target size, and the target size of the orbiting scroll can be obtained by the first orbiting scroll target size and the second orbiting scroll target size, thereby obtaining the orbiting scroll target size and the fixed scroll target size to improve the assembly effect.

[0087] The target dynamic and static disk matching size matrix table is a dynamic and static disk matching size matrix table after the dynamic and static disk matching sizes are shifted after being subjected to normal distribution.

[0088] In this embodiment, the first orbiting scroll required size and the second orbiting scroll required size are obtained based on the orbiting scroll required size; the first stationary scroll required size and the second stationary scroll required size are obtained based on the stationary scroll required size; the stationary scroll matching size interval in the target orbiting and stationary disk matching size matrix table is queried through the first stationary scroll required size and the second stationary scroll required size to obtain the first stationary scroll target size, the second stationary scroll target size and the orbiting scroll matching size interval corresponding to the stationary scroll required size; the first orbiting scroll target size and the second orbiting scroll target size are matched in the orbiting scroll matching size interval through the first orbiting scroll required size and the second orbiting scroll required size; the stationary scroll target size is obtained through the first stationary scroll target size and the second stationary scroll target size; the orbiting scroll target size is obtained through the first orbiting scroll target size and the second orbiting scroll target size, which can reduce the precision sensitivity of the orbiting and stationary disks of the compressor, make the processing molds of the orbiting and stationary disks easy to realize and reduce the mold cost; and at the same time reduce the scrap rate of parts.

[0089] refer to Figure 5 , Figure 5 It is a schematic flow chart of the third embodiment of the method for determining compressor scroll assembly parameters of the present invention.

[0090] Based on the first embodiment described above, the compressor scroll assembly parameter determination method of this embodiment further includes, before step S20:

[0091] Step 11: Collect the sample dimensions of the orbiting scroll and the sample dimensions of the stationary scroll when the clearance between the orbiting and stationary scrolls is matched.

[0092] It should be noted that before determining the assembly parameters, a matrix table of movable and stationary disk matching dimensions can be established in advance, and then multiple movable scroll disk dimensions and multiple stationary scroll disk dimensions can be collected under the condition of clearance matching of the movable and stationary disks. The clearance matching is the clearance under which the movable and stationary disks of the compressor do not collide and the compressor works at normal efficiency. The movable scroll sample dimensions are obtained through the dimensions of multiple movable scrolls, and the stationary scroll sample dimensions are obtained through the dimensions of multiple stationary scrolls.

[0093] Step 12: Divide the orbiting scroll sample size and the stationary scroll sample size into multiple levels to obtain multiple orbiting scroll sample size intervals and multiple stationary scroll sample size intervals.

[0094] In a specific implementation, the orbiting scroll sample size and the stationary scroll sample size can be divided into n level intervals respectively, for example, 1 represents the minimum level interval, n represents the maximum level interval, and the others increase in sequence.

[0095] Step 13: Establish a first correlation relationship between a plurality of the movable scroll sample size intervals and a plurality of stationary scroll sample size intervals to obtain a reference movable and stationary scroll matching size matrix table.

[0096] The matching of the first orbiting scroll size and the second stationary scroll size can determine the sizes of scenarios A1 and A2 when the pressure chamber of the compressor is filled with refrigerant pressure. The matching of the first stationary scroll size and the second orbiting scroll size can determine the sizes of scenarios B1 and B2 when the pressure chamber of the compressor is filled with refrigerant pressure.

[0097] In a specific implementation, a first association relationship between multiple movable scroll sample size intervals and multiple fixed scroll sample size intervals can be established to avoid collisions between the movable and fixed disks due to the sizes of A1, A2, B1, and B2 being too small, and to avoid the sizes of A1, A2, B1, and B2 being too large, resulting in high-pressure refrigerant flowing out of the gaps A1, A2, B1, and B2 between the movable and fixed disks of the compressor when the compressor compresses the refrigerant, resulting in reduced compressor efficiency. A reference movable and fixed disk matching size matrix table is obtained through the first association relationship. As shown in Table 2, Table 2 is a reference movable and fixed disk matching size matrix table.

[0098] Table 2

[0099]

[0100] Step 14: Process the reference moving-static disk matching size matrix table to obtain a target moving-static disk matching size matrix table.

[0101] It should be noted that due to factors such as the consistency of manufacturing molds, the periodic wear of processing tools, the accuracy of inspection fixtures, etc., the ideal size value may deviate. According to the size matching in Table 2 above, a large number of scrapped products may appear. From the standard normal distribution analysis, the actual median μ deviates from the ideal design u value, resulting in the size of the moving disk and the static disk deviating seriously to one size side at the same time, making it impossible to match the other size side, that is, the scrap rate increases. Therefore, the reference moving and static disk matching size matrix table can be processed to obtain the target moving and static disk matching size matrix table.

[0102] In a specific implementation, the reference moving and static disk matching size matrix table is processed to obtain a target moving and static disk matching size matrix table, including the steps of: obtaining an actual moving scroll size and an actual static scroll size produced according to the reference moving and static disk matching size matrix table; calculating a moving scroll size deviation and a static scroll size deviation according to the actual moving scroll size and the actual static scroll size and each reference moving and static disk matching size in the reference moving and static disk matching size matrix table; calculating the probability of occurrence of the moving scroll size deviation and the static scroll size deviation; and performing a normal distribution on the reference moving and static disk matching size matrix table based on the probability through a normal distribution function to obtain a target moving and static disk matching size matrix table.

[0103] It should be noted that in order to reduce the scrap rate, it is necessary to sacrifice the consistency of some scroll disks while solving the abnormal noise. The reason for the abnormal noise is that the assembly gap between the moving disk and the static disk is so small that it fits tightly, so the abnormal noise will occur. Therefore, the assembly gap can be set to > 0. The minimum tolerance for matching the moving disk and the static disk in actual production is that the assembly gap between the moving disk and the static disk is > a certain threshold.

[0104] The matching of the movable and static disks follows the rule that movable disk n is matched with static scroll disk 1, movable scroll disk n-1 is matched with static scroll disk 2, movable scroll disk n-2 is matched with static scroll disk 3, and so on. Considering the production consistency, the median of the static scroll disk needs to be matched with the movable scroll disk on one side. Although the performance consistency of the compressor is slightly different at this time, this can well solve the problem of high product scrap rate.

[0105] The actual orbiting scroll size and the actual stationary scroll size produced according to the reference orbiting and stationary disk matching size matrix table can be collected, and the orbiting scroll size deviation and the stationary scroll size deviation, that is, the actual size distribution deviation, are calculated by referring to each reference orbiting and stationary disk matching size in the orbiting and stationary disk matching size matrix table, and the probability of the orbiting scroll size deviation and the stationary scroll size deviation is statistically calculated, and is represented by the area represented by the two-dimensional coordinates of the normal distribution function, so as to perform a normal distribution on the reference orbiting and stationary disk matching size matrix table, that is, an equal-area gradient average normal distribution, such as Figure 6 As shown, Figure 6 It is a schematic diagram of the normal distribution of the reference dynamic and static disk matching size matrix table, S1, S2, S..., Sn represent the equally divided areas, μ1, μ2, μ..., μn are certain size thresholds of C, D, E, F of the dynamic disk or static disk corresponding to the equally divided areas, so as to obtain the size matching table after the normal distribution is shifted, that is, the target dynamic and static disk matching size matrix table.

[0106] As an example, reasonable A1, A2, B1, B2 gap matching depends on the size matching of C, D, E, F. In order to make the matching reasonable, C, D, E, F sizes are respectively divided into three levels, namely, upper limit interval, median interval, and lower limit interval, as shown in Table 3 below. Table 3 is an initial dynamic and static disk matching size matrix table. In Table 3, the matching of the static disk C size and the dynamic disk D size can determine the size of A1 and A2 in the scenario where the pressure chamber of the compressor is filled with refrigerant pressure. In this way, the upper limit interval of the static disk C size is matched with the lower limit interval of the dynamic disk D size, the median interval of the static disk C size is matched with the median interval of the dynamic disk D size, and the lower limit interval of the static disk C size is matched with the upper limit interval of the dynamic disk D size; the matching of the static disk E size and the dynamic disk F size can determine the size of B1 and B2 in the scenario where the pressure chamber of the compressor is filled with refrigerant pressure. In this way, the upper limit interval of the static disk E size is matched with the lower limit interval of the dynamic disk F size, the median interval of the static disk E size is matched with the median interval of the dynamic disk F size, and the lower limit interval of the static disk E size is matched with the upper limit interval of the dynamic disk F size. To avoid the collision of the moving and static disks caused by the small size of A1, A2, B1, B2, and to avoid the collision of the moving and static disks caused by the large size of A1, A2, B1, B2, and to reduce the efficiency of the compressor when the compressor compresses the refrigerant, the high-pressure refrigerant flows out from the gaps between the moving and static disks of the compressor, A1, A2, B1, B2. This solves the problem of the compressor colliding and making abnormal noises at low speeds, and the efficiency reduction at high speeds, and controls the consistency of the product well.

[0109] This embodiment collects sample sizes of the movable scroll and the stationary scroll when the clearance between the movable and stationary disks is matched; divides the movable scroll sample sizes and the stationary scroll sample sizes into multiple levels to obtain multiple movable scroll sample size intervals and multiple stationary scroll sample size intervals; establishes a first association relationship between the multiple movable scroll sample size intervals and the multiple stationary scroll sample size intervals to obtain a reference movable and stationary disk matching size matrix table; processes the reference movable and stationary disk matching size matrix table to obtain a target movable and stationary disk matching size matrix table, thereby ensuring the accuracy of matching between the movable scroll and the stationary scroll and reducing the scrap rate of the movable scroll and the stationary scroll during production.

[0110] refer to Figure 7 , Figure 7 It is a schematic flow chart of a fourth embodiment of a method for determining compressor scroll assembly parameters according to the present invention.

[0111] Based on the first embodiment described above, the compressor scroll assembly parameter determination method of this embodiment further includes, after step S30:

[0112] Step S31: assembling the compressor scroll according to the orbiting scroll target size and the fixed scroll target size.

[0113] It should be noted that after the orbiting scroll target size and the fixed scroll target size are obtained, the scroll of the compressor can be assembled according to the orbiting scroll target size and the fixed scroll target size.

[0114] Specifically, the process of assembling the scroll includes: obtaining a second correlation between the sizes of the movable scroll and the stationary scroll and the clearance between the movable and stationary scrolls; determining a target clearance through the second correlation, the movable scroll target size and the stationary scroll target size; and assembling the compressor scroll based on the target clearance according to the movable scroll target size and the stationary scroll target size.

[0115] In a specific implementation, there is a second correlation between the size of the orbiting scroll and the fixed scroll and the clearance of the orbiting and fixed disks. Different orbiting scroll sizes and fixed scroll sizes correspond to different orbiting and fixed disk clearances. The second correlation between the size of the orbiting scroll and the fixed scroll and the clearance of the orbiting and fixed disks can be established in advance. For example, the size of the orbiting scroll and the fixed scroll are q1 and w1 respectively, and the clearance of the orbiting and fixed disks is m1. The size of the orbiting scroll and the fixed scroll are q2 and w2 respectively, and the clearance of the orbiting and fixed disks is m2. The target clearance can be determined by the second correlation, the orbiting scroll target size, and the fixed scroll target size.

[0116] In a specific implementation, the orbiting scroll and the fixed scroll of the compressor may be assembled according to the target clearance using the orbiting scroll target size and the fixed scroll target size.

[0117] Further, the step of assembling the compressor scroll based on the target clearance according to the orbiting scroll target size and the fixed scroll target size specifically includes:

[0118] Based on the target clearance, axial clearance data and radial clearance data between the fixed scroll and the movable scroll of the compressor are obtained; the first movable scroll target size and the second movable scroll target size are obtained through the movable scroll target size; the first fixed scroll target size and the second fixed scroll target size are obtained through the fixed scroll target size; based on the radial clearance data, the compressor scroll is assembled according to the first movable scroll target size and the second fixed scroll target size; based on the axial clearance data, the compressor scroll is assembled according to the second movable scroll target size and the first fixed scroll target size.

[0119] It should be noted that if Figure 3As shown, the target clearance includes axial clearance data and radial clearance data, the axial clearance data includes A1 and A2, the radial clearance data includes B1 and B2, and the compressor scroll is assembled according to the first movable scroll target size and the second fixed scroll target size, and the radial clearance between the movable scroll and the fixed scroll is controlled to be the radial clearance data, the compressor scroll is assembled according to the second movable scroll target size and the first fixed scroll target size, and the axial clearance between the movable scroll and the fixed scroll is controlled to be the axial clearance data, so that the compressor scroll can be assembled according to a reasonable clearance, which solves the problem of abnormal noise caused by low-speed collision of the compressor, reduced efficiency at high speed, and good control of product consistency.

[0120] In this embodiment, the compressor scroll is assembled by using the orbiting scroll target size and the stationary scroll target size, so that the compressor scroll can be assembled according to appropriate orbiting and stationary scroll sizes, thereby improving the assembly effect.

[0130] In one embodiment, the acquisition module 20 is further used to assemble the compressor scroll according to the orbiting scroll target size and the fixed scroll target size.
