[0002] The closed rolling rotor compressor is widely used in the field of refrigeration and air conditioning due to its advantages of few parts, simple structure and reliable operation. Due to the fully closed structure, the shell is sealed mainly by welding and shrink sleeve. Although this method can make the compressor have better integrity and sealing, its disadvantages are also more significant. Mainly due to this traditional integrated structural design, as long as there is an abnormality in any of the different parts inside the compressor, the compressor will be unable to continue to be used and the whole machine will be directly scrapped. The later maintenance and after-sales cycle is long and the cost is high. Summary of the invention

[0003] In response to the above-mentioned problems in the prior art, the present application proposes a compressor structure, electrical equipment and abnormality troubleshooting method with a reconfigurable module, which reduces the material cost and time cost of compressor development.

[0005] Through this implementation, the compressor is divided into three parts: a motor module, a pump body module and a liquid distributor module. During the compressor development process, the modules with matching connection parts can be reorganized and matched, thereby realizing the development of the compressor in a faster cycle and matching the optimal compressor combination. In the compressor development, there is no need for trial production of the whole machine. Through the form of mutual matching and combination, the compressor development cost and time cost can be reduced. When the compressor fails, the module can be checked to quickly find out the cause of the compressor abnormality, and the abnormal module can be replaced, saving material costs.

[0006] In one embodiment, a first groove and / or a first boss is formed at one end of the second crankshaft close to the first crankshaft, and the first crankshaft is provided with a second boss engaged with the first groove and / or a second groove engaged with the first boss.

[0007] Through this embodiment, the second crankshaft is connected to the first crankshaft through a mortise and tenon structure using the mortise and tenon principle, which facilitates the disassembly and installation of the first crankshaft and the second crankshaft, and ensures that the connection stability between the first crankshaft and the second crankshaft is good during the operation of the compressor.

[0008] In one embodiment, the groove includes a guide groove and a limit groove, the limit groove is arranged on the inner wall of the guide groove, the boss includes a guide section and a limit section respectively cooperating with the guide groove and the limit groove, and the limit section can be engaged into the limit groove through the guide groove.

[0009] Through this implementation, when the first crankshaft is connected to the second crankshaft, the limiting section is located in the limiting groove, and the limiting groove limits the limiting section, thereby limiting the axial relative movement of the first crankshaft and the second crankshaft, avoiding axial separation of the first crankshaft and the second crankshaft, and ensuring the connection stability between the first crankshaft and the second crankshaft.

When the first shell is connected to the second shell, the interior of the motor module and the pump body module are connected.

[0017] Through this embodiment, the first connecting plate and the second connecting plate are added to connect the first connecting plate and the second connecting plate to achieve the connection between the first shell and the second shell. The first connecting plate and the second connecting plate are connected by a high-strength bolt assembly. Multiple groups of high-strength bolt assemblies can be provided to ensure the stability of the connection between the first connecting plate and the second connecting plate.

[0018] In one embodiment, the first connection structure further includes a limiting protrusion disposed at a mutually buckled portion of the first shell and the second shell, and a limiting groove matched with the limiting protrusion.

[0019] According to this embodiment, the contact surface of the first connecting plate and the second connecting plate is stepped or sawtooth-fitted, which improves the integrity of the first connecting plate and the second connecting plate, can play a role in rapid positioning when installing the first connecting plate and the second connecting plate, and prevents the first connecting plate and the second connecting plate from radially offsetting, and realizes multi-level sealing through stepped or sawtooth-fitted, thereby improving the sealing effect.

[0020] In one embodiment, a sealing gasket is provided between the first connecting plate and the second connecting plate.

[0021] Through this embodiment, by providing a sealing gasket, the connection sealing performance between the first connecting plate and the second connecting plate is improved, so that the internal space formed by the first shell and the second shell is kept relatively airtight, and at the same time, the effect of shock absorption and noise reduction is achieved.

[0022] In one embodiment, the liquid dispenser module further comprises a liquid dispenser body, the liquid dispenser outlet pipe extends from the end of the liquid dispenser body, and the liquid dispenser body is fixedly connected to the main housing where the pump body module is located through the second connecting structure and the motor module;

[0023] The second connection structure includes an insert plate arranged on the outer wall of the dispenser body and two fixed plates arranged on the outer wall of the main shell and spaced from each other. The insert plate can extend into the gap between the two fixed plates and be connected to the two fixed plates by fasteners.

[0024] Through this embodiment, a detachable connection between the dispenser and the first shell is achieved, thereby improving the integrity of the dispenser module, the motor module and the main body module after installation, and preventing the dispenser module from shaking randomly relative to the motor module or the pump body module, which would cause the problem of unstable connection between the dispenser outlet pipe and the pump body inlet pipe.

[0025] In one embodiment, a connecting pipe is sleeved on the outlet pipe of the liquid dispenser, the connecting pipe is threadedly connected to the inlet pipe of the pump body, and the pipe opening of the outlet pipe of the liquid dispenser is a flared structure.

[0026] Through this embodiment, a threaded connection is adopted, which makes disassembly and installation convenient and quick, and can ensure the sealing after connection.

[0034] In one embodiment, if the compressor does not return to normal, the replaced functional modules corresponding to the functional module set are replaced with the original modules before replacement. Only the damaged modules are replaced, and the normal modules are retained, saving replacement costs.

[0035] Through this embodiment, by replacing and verifying the modules, it is possible to more quickly determine whether the abnormal problem of the compressor is any one of the three modules, or any combination of two modules, or all three modules have problems at the same time, and the cause of the abnormality can be discovered more quickly and handled in a timely manner.

DETAILED DESCRIPTION

[0048] The present invention will be further described below in conjunction with the accompanying drawings.

[0049] Example 1

[0050] The compressor structure of the reconfigurable module of the present invention includes a motor module 10, a pump body module 20 and a dispenser module 30; the motor module 10 includes a first crankshaft 11, the pump body module 20 includes a second crankshaft 21 detachably connected to the first crankshaft 11, the pump body module 20 also includes a pump body inlet pipe 22, and the dispenser module 30 includes a dispenser outlet pipe 31 detachably connected to the pump body inlet pipe 22.

[0051] Specifically, the compressor is divided into three parts, namely, a motor module 10, a pump body module 20 and a liquid distributor module 30. During the compressor development process, the modules with matching connecting parts can be reorganized and matched, thereby realizing the development of the compressor in a faster cycle and matching the optimal compressor combination. In the compressor development, there is no need for trial production of the entire machine. By matching and combining the modules, the compressor development cost and time cost can be reduced. When the compressor fails, the module can be checked to quickly find out the cause of the compressor abnormality, and the abnormal module can be replaced, saving material costs.

[0052] Furthermore, a first groove and / or a first boss is formed at one end of the second crankshaft 21 close to the first crankshaft 11, and the first crankshaft 11 is provided with a second boss engaged with the first groove and / or a second groove engaged with the first boss.

[0053] The second crankshaft 21 is connected to the first crankshaft 11 by a mortise and tenon structure based on the mortise and tenon principle, which facilitates the disassembly and installation of the first crankshaft 11 and the second crankshaft 21 and ensures good connection stability between the first crankshaft 11 and the second crankshaft 21 during the operation of the compressor.

[0054] Furthermore, the groove includes a guide groove 211 and a limiting groove 212, the limiting groove 212 is arranged on the inner wall of the guide groove 211, the boss includes a guide section 111 and a limiting section 112 respectively cooperating with the guide groove 211 and the limiting groove 212, and the limiting section 112 can be engaged into the limiting groove 212 through the guide groove 211.

[0055] When the first crankshaft 11 is connected to the second crankshaft 21, the limiting section 112 is located in the limiting groove 212, and the limiting groove 212 limits the limiting section 112, thereby limiting the axial relative movement of the first crankshaft 11 and the second crankshaft 21, avoiding axial separation between the first crankshaft 11 and the second crankshaft 21, and ensuring the connection stability between the first crankshaft 11 and the second crankshaft 21.

[0056] Specifically, the width of the guide groove 211 is L1, and the overall width of the guide section 111 and the limiting section 112 is L2, L2 is not greater than L1, preferably L2 is equal to L1, to ensure that the guide section 111 and the limiting section 112 as a whole can smoothly enter the guide groove 211. When the limiting section 112 is located in the limiting groove 212, the outer wall of the limiting section 112 fits with the inner wall of the limiting groove 212, the width of the guide section 111 is δ2, and the gap between the side wall of the guide section 111 away from the limiting section 112 and the inner wall of the guide groove 211 is δ1, preferably, δ1 is equal to δ2. During the connection process between the first crankshaft 11 and the second crankshaft 21, the mortise and tenon boss of the first crankshaft 11 enters into the guide groove 211 of the second crankshaft 21, and then the first crankshaft 11 rotates relative to the second crankshaft 21, so that the limiting section 112 of the first crankshaft 11 enters into the limiting groove 212 of the second crankshaft 21, so that the mortise and tenon boss and the mortise and tenon groove are completely matched, and the first crankshaft 11 and the second crankshaft 21 will not be separated during the operation of the compressor.

[0057] Specifically, it needs to be further explained that all the limit grooves 212 can be simultaneously located on a side wall of the limit groove 212 along the clockwise or counterclockwise rotation direction of the second crankshaft 21, that is, when the first crankshaft 11 is connected to the second crankshaft 21, when the crankshafts rotate clockwise or counterclockwise, it is ensured that the limit section 112 will enter the limit groove 212, thereby limiting the axial movement of the first crankshaft 11 and the second crankshaft 21 and preventing the first crankshaft 11 from separating from the second crankshaft 21. The above situation satisfies the condition when the first crankshaft 11 always rotates in one direction. Furthermore, on the basis that all the limit grooves 212 are located on the same direction side wall of the guide groove 211, a guide groove 211 can be added between adjacent guide grooves 211, and a limit groove 212 can be expanded on the inner wall of the newly added guide groove 211. The newly added limit groove 212 is opposite to the original limit groove 212, that is, when the first crankshaft 11 rotates clockwise or counterclockwise, half of the limit segments 112 are located in the limit groove 212, and the other half of the limit segments 112 are located outside the limit groove 212, thereby ensuring the connection stability between the first crankshaft 11 and the second crankshaft 21.

[0058] Furthermore, there are a plurality of grooves, all of which extend radially on the end surface of the crankshaft and deflect circumferentially at a certain angle, and all of the grooves have the same deflection direction.

[0059] The straight extension line of the groove does not intersect with the center of the crankshaft, but is at a certain distance from the center of the crankshaft and is biased towards the rotation direction of the crankshaft. Compared with the straight extension line of the groove intersecting with the center of the crankshaft, the contact surface between the groove and the protrusion can be increased, the friction between the contact surfaces can be increased to prevent falling off, and at the same time, the force on the mortise and tenon boss during the rotation of the crankshaft is reduced, thereby improving the reliability of the mortise and tenon connection.

[0060] Specifically, in order to evenly distribute the load, the number of the mortise and tenon grooves is an even number, and all the mortise and tenon grooves are distributed in a circular array to ensure that the distances between adjacent mortise and tenon grooves are the same.

[0061] Furthermore, the center of the end face of the first crankshaft 11 has a first screw hole or a first stud, the end face of the second crankshaft 21 has a second stud that cooperates with the first screw hole or a second screw hole that cooperates with the first stud, and the tightening direction of the threaded structure between the screw hole and the stud is the same as the rotation direction of the crankshaft.

[0062] Another connection method is provided for the first crankshaft 11 and the second crankshaft 21. The tightening direction of the threaded connection is consistent with the rotation direction of the crankshaft. During the rotation of the crankshaft, the first crankshaft 11 and the second crankshaft 21 will not be subjected to the force in the loosening direction of the thread, thereby ensuring the stability of the connection between the first crankshaft 11 and the second crankshaft 21.

[0063] Furthermore, it also includes a main housing for accommodating the motor module 10 and the pump body module 20, the main housing includes a first housing 14 and a second housing 25 that are interlocked, the motor module 10 is arranged in the first housing 14, and the pump body module 20 is arranged in the second housing 25. The motor module 10 also includes a motor rotor 12, a motor stator 13 and a first housing 14, one end of the first housing 14 is an open structure, the outer wall of the motor stator 13 is connected to the inner wall of the first housing 14, the motor rotor 12 is rotatably arranged in the motor stator 13, and the first crankshaft 11 is connected to the motor rotor 12; the pump body module 20 also includes a cylinder 23, a roller 24 and a second housing 25, one end of the second housing 25 is an open structure, the cylinder 23 is arranged in the second housing 25, the pump body inlet pipe 22 passes through the second housing 25 and communicates with the inside of the cylinder 23, the second crankshaft 21 is connected to the roller 24 arranged in the cylinder 23, and the second housing 25 is detachably connected to the first housing 14.

[0064] The first shell 14 and the second shell 25 are detachably connected, the motor module 10 composed of the motor stator 13 and the electronic rotor and other structures is arranged in the first shell 14, and the pump body module 20 composed of the cylinder 23 and the roller 24 and other structures is arranged in the second shell 25. When the first shell 14 is connected to the second shell 25, the interior of the motor module 10 and the pump body module 20 are connected. When the module needs to be replaced, the first shell 14 and the second shell 25 are separated, and the replacement of the module is convenient and quick.

[0065] Specifically, when the motor module 10, the pump body module 20 and the liquid distributor module 30 are connected as a whole, the first shell 14 is sealed and connected to the second shell 25, and a connected cavity is formed inside the first shell 14 and inside the second shell 25. The liquid distributor outlet pipe 31 of the liquid distributor module 30 is connected to the pump body inlet pipe 22, and an upper cover is provided at one end of the motor module 10 away from the opening end of the first shell 14, and an exhaust pipe and a terminal portion of the terminal are provided on the upper cover. A suction pipe is connected to the upper end of the liquid distributor module 30, and the refrigerant returning from the evaporator to the pump body module 20 is separated into gas and liquid, and only the gas is allowed to enter the pump body module 20 through the liquid distributor outlet pipe 31, thereby preventing the liquid refrigerant from entering the pump body module 20 to destroy the lubrication or damage the roller 24. An upper flange and a lower flange are respectively provided at the upper and lower ends of the cylinder 23, and the upper flange can support the rotation of the second crankshaft 21, and the upper flange and the lower flange limit the roller 24 and form a relatively closed space.

[0066] Furthermore, a first connecting structure is arranged between the first shell 14 and the second shell 25, and the first connecting structure includes a first connecting plate 141 and a second connecting plate 251 respectively arranged on the outer walls of the opening ends of the first shell 14 and the second shell 25, and the first connecting plate 141 and the second connecting plate 251 are connected by a fastener 411.

[0067] The first shell 14 and the second shell 25 are connected by adding a first connecting plate 141 and a second connecting plate 251. The first connecting plate 141 and the second connecting plate 251 are connected by a high-strength bolt assembly. Multiple groups of high-strength bolt assemblies can be provided to ensure the stability of the connection between the first connecting plate 141 and the second connecting plate 251.

[0068] Specifically, a plurality of aligned through holes are provided on the first connecting plate 141 and the second connecting plate 251, and high-strength bolt assemblies penetrate the through holes to connect and fix the first housing 14 and the second housing 25. Furthermore, the high-strength bolt assemblies can also be replaced with fasteners 411 such as quick buckles and quick clamps for connection.

[0069] Furthermore, the first connection structure also includes a limiting protrusion arranged at the mutually buckled position of the first shell 14 and the second shell 25 and a limiting groove 212 matched with the limiting protrusion.

[0070] Improving the integrity of the first connecting plate 141 and the second connecting plate 251 can play a role in quick positioning during installation of the first connecting plate 141 and the second connecting plate 251, while avoiding radial offset of the first connecting plate 141 and the second connecting plate 251, and achieving multi-level sealing through step surface fitting or serration cutting to improve the sealing effect.

[0071] Furthermore, a sealing gasket 410 is provided between the first connecting plate 141 and the second connecting plate 251. By providing the sealing gasket 410, the connection sealing performance of the first connecting plate 141 and the second connecting plate 251 is improved, so that the internal space formed by the first shell 14 and the second shell 25 is relatively airtight, and the effect of vibration reduction and noise reduction is achieved.

[0072] Specifically, the sealing gasket 410 can be made of rubber, which has low manufacturing cost and good sealing effect.

[0073] Furthermore, the dispenser module 30 also includes a dispenser body 32, and the dispenser outlet pipe 31 extends from the end of the dispenser body 32. The dispenser body 32 is fixedly connected to the main shell where the pump body module 20 is located through a second connecting structure and the motor module 10. The second connecting structure includes an insert plate 33 arranged on the outer wall of the dispenser body 32 and two fixed plates spaced from each other arranged on the outer wall of the main shell. The insert plate 33 can extend into the gap between the two fixed plates and be connected to the two fixed plates through fasteners 411.

[0074] A detachable connection is achieved between the dispenser and the first shell 14, which improves the integrity of the dispenser module 30, the motor module 10 and the main body module after installation, and avoids the dispenser module 30 from shaking freely relative to the motor module 10 or the pump body module 20, which would cause the problem of unstable connection between the dispenser outlet pipe 31 and the pump body inlet pipe 22.

[0075] Specifically, the plug plate 33 is in the shape of a straight plate, with a threaded hole on the plug plate 33, and the two fixing plates also have corresponding threaded holes. During installation, the plug plate 33 on the dispenser body 32 is inserted between the two fixing plates, and then the dispenser body 32 and the first shell 14 are fastened together by a threaded bolt assembly to achieve the connection between the dispenser module 30 and the motor module 10.

[0076] Furthermore, if Figure 5 As shown, it is Figure 1 Based on the further optimized structure, Figure 5 The structure shown is not Figure 1 As shown in . A connecting pipe 311 is sleeved on the liquid dispenser outlet pipe 31, and the connecting pipe 311 is threadedly connected to the pump body inlet pipe 22, and the pipe mouth of the liquid dispenser outlet pipe 31 is a flared structure. The connecting pipe 311 includes a threaded section connected to the pump body inlet pipe 22 and a connecting section connected to the liquid dispenser outlet pipe 31, and the connecting section is a contracted structure, and the inner diameter of the connecting section is slightly larger than the outer diameter of the liquid dispenser outlet pipe 31, and smaller than the maximum outer diameter of the flared opening. The connecting pipe 311 can slide along the outer wall of the liquid dispenser outlet pipe 31, and the flared structure plays a role in preventing the connecting pipe 311 from slipping. One end of the connecting pipe 311 is provided with an internal thread, and the pump body inlet pipe 22 is provided with an external thread matching the internal thread, and the inner diameter of the threaded section is larger than the outer diameter of the flared structure to ensure that the connecting pipe 311 and the pump body inlet pipe 22 can be threadedly connected. When connecting, first align the liquid distributor outlet pipe 31 with the pump body inlet pipe 22 horizontally, and rotate the connecting pipe 311 so that the connecting pipe 311 and the pump body inlet pipe 22 are tightly connected through threads, thereby realizing the tight connection between the liquid distributor outlet pipe 31 and the pump body inlet pipe 22. The outer diameter of the flared port matches the inner diameter of the pump body inlet pipe 22 so that the flared port structure can enter the pump body inlet pipe 22, or the outer diameter of the flared port matches the outer diameter of the pump body inlet pipe 22 so that the flared port structure just abuts against the outer wall of the inlet end of the pump body inlet pipe 22.

[0078] Example 2

[0079] This embodiment provides a method for troubleshooting an abnormality of a compressor structure of a reconfigurable module, comprising the following steps:

[0080] Step S000: determine the mode;

[0081] Step S010: determining a replacement mode according to an abnormal signal of the compressor;

[0082] Step S020: determining the number of functional modules in the functional module set according to the number of functional modules to be replaced at one time determined by the replacement mode;

[0083] Specifically, the compressor is provided with multiple functional modules. After the compressor fails, it cannot be determined whether the problem occurs in a specific functional module or in multiple functional modules at the same time. Therefore, it is necessary to determine the number of functional modules to be replaced to avoid replacing normal functional modules and reduce replacement costs.

[0084] In addition, it is also possible to combine the actual situation, such as the frequency of abnormalities in each functional module when abnormal conditions occurred in the past, determine the specific module types and corresponding quantities with a higher frequency of abnormal conditions based on these historical data, and determine the replacement mode (corresponding to the number of modules with a higher frequency of abnormal conditions) and replace this type of module first when replacing.

[0085] Step S100: selecting any one or more functional modules from a plurality of functional modules constituting the compressor for replacement according to an abnormal signal of the compressor, and determining a set of functional modules to be replaced;

[0086] Step S200: determining whether the compressor has returned to normal;

[0087] Step S300: If the compressor does not return to normal, the replaced functional module of the corresponding functional module set is replaced with the original module before the replacement.

[0088] Specifically, only damaged modules are replaced and normal modules are retained, thus saving replacement costs.

[0089] Step S400: If the compressor has not returned to normal, the replaced functional modules of the corresponding functional module set are replaced with the original modules before replacement, and any one or more functional modules are reselected from the functional modules for replacement, and the functional module set to be replaced is re-determined, and the re-determined functional module set does not completely overlap with the previously determined functional module set.

[0090] Specifically, during the detection process, the modules that have not been replaced are gradually replaced to ensure that the damaged modules can be replaced.

[0091] Example 3

[0092] Based on Example 1, this example proposes a method for troubleshooting an abnormality of a compressor structure of a reconfigurable module, comprising the following steps:

[0093] Step S000: determine the mode; the modes include single module detection, dual module detection and triple module detection;

[0094] Step S010: determining a replacement mode according to an abnormal signal of the compressor;

[0095] Step S011: Single module detection: Perform replacement verification on the motor module 10, the pump module 20 and the liquid distributor module 30. After replacing any of the above modules, if the compressor can start normally, then the module is an abnormal module;

[0096] Step S012: Dual module detection: If the single module detection cannot find the abnormal module, the motor module 10 and the pump module 20, the motor module 10 and the liquid distributor module 30, the pump module 20 and the liquid distributor module 30 are replaced and verified. After replacing any of the above combination modules, if the compressor can start normally, the combination module is an abnormal module;

[0097] Step S013: Three-module replacement: If the single-module detection and the dual-module detection cannot find the abnormal module, the motor module 10, the pump body module 20 and the dispenser module 30 are replaced at the same time.

[0098] Step S020: determining the number of functional modules in the functional module set according to the number of functional modules to be replaced at one time determined by the replacement mode;

[0099] Specifically, the compressor is provided with multiple functional modules. After the compressor fails, it cannot be determined whether the problem occurs in a specific functional module or in multiple functional modules at the same time. Therefore, it is necessary to determine the number of functional modules to be replaced to avoid replacing normal functional modules and reduce replacement costs.

[0100] Step S100: selecting any one or more functional modules from a plurality of functional modules constituting the compressor for replacement according to an abnormal signal of the compressor, and determining a set of functional modules to be replaced;

[0101] Specifically, according to the replacement mode determined in the aforementioned steps, a corresponding number and type of functional modules are selected for replacement, and the selected functional modules are used as a functional module set.

[0102] Step S200: determining whether the compressor has returned to normal;

[0103] Step S300: If the compressor has not returned to normal, the replaced functional modules of the corresponding functional module set are replaced with the original modules before replacement, and any one or more functional modules are reselected from the functional modules for replacement, and the functional module set to be replaced is re-determined, and the re-determined functional module set does not completely overlap with the previously determined functional module set.

[0104] By verifying the replacement of the modules, it is possible to more quickly determine whether the compressor abnormality is caused by any one of the three modules, any combination of two modules, or all three modules at the same time, and the cause of the abnormality can be discovered and handled in a timely manner. During the processing, only the abnormal module needs to be replaced, which can save a lot of material costs.

[0105] For example: In the process of abnormality troubleshooting for the compressor structure in this case, the three modules are replaced and reorganized to achieve abnormality troubleshooting. According to the historical replacement and maintenance data, the corresponding functional modules with a higher frequency of abnormalities in the compressor are determined, and replaced first, and the motor module 10, pump module 20, and liquid distributor module 30 are replaced and verified; if replacing only a single module still cannot solve the abnormality, the double module is replaced, as follows: motor module 10 + pump module 20, motor module 10 + liquid distributor module 30, pump module 20 + liquid distributor module 30; if replacing a single module or a double module cannot solve the problem, it is necessary to replace all three modules, that is, replace the entire compressor. Example: First replace the motor module 10, and then start it. If the compressor can start normally, the abnormal component of the compressor is the motor module 10. If the compressor still cannot start normally after replacing the motor module 10, replace the new pump module 20, and the operation method is the same as replacing the motor module 10. Finally, the liquid distributor module 30 is replaced, mainly because this module has fewer abnormalities except for less blockage. If the above three single-module replacement methods cannot solve the compressor abnormality, the dual-module replacement method is selected. If the problem still cannot be solved, the most unfavorable solution is to replace the entire compressor. In addition, for compressors with other structures, four-module, five-module and other modes can be further carried out, according to the compressor module structure division and quantity.

[0106] Specifically, since the dispenser module 30 rarely has abnormalities except for the less frequent blockages, during fault detection, the single module can be replaced smoothly as follows: the motor module 10, the pump module 20 and the dispenser module 30; the dual module can be replaced smoothly as follows: the combination of the motor module 10 and the pump module 20, the combination of the motor module 10 and the dispenser module 30, and the combination of the pump module 20 and the dispenser module 30. If the three single module replacement methods cannot solve the compressor abnormality, the dual module replacement method is selected. If the problem still cannot be solved, the most unfavorable solution is adopted, that is, replacing the entire compressor.

[0107] Specifically, it is necessary to further explain that the structural diagram of the present application is a closed rolling rotor compressor. For other compressor structures of closed rotary compressors, such as two-stage compressors, two-stage enthalpy increasing compressors, multi-stage compressors, multi-stage enthalpy increasing compressors, and jet enthalpy increasing compressors, the method in this proposal can also be used for design. This proposal mainly takes a single-stage rolling rotor compressor as an example. And for scroll compressors, screw compressors, and piston compressors, the technical means provided in this proposal can also be used to modularize their structures.
