In order to solve the problems of vibration and large noise of a fluid machine in the running process in the prior art, the application provides the fluid machine and heat exchange equipment with the fluid machine. The fluid machine in the present application mainly refers to a compressor.
As shown in fig. 1 to 4, the fluid machine includes a rotation shaft 50, a gas-liquid separation assembly, and a cylinder 30. The gas-liquid separation assembly has a separation chamber 411, at least a portion of the rotating shaft 50 penetrates into the separation chamber 411 and can rotate relative to the separation chamber 411, and the mixed refrigerant enters the separation chamber 411 and is separated into gas and liquid under the rotation action of the rotating shaft 50. The gas after the gas-liquid separation enters the cylinder 30.
By applying the technical scheme of the embodiment, the gas-liquid separation assembly and the rotating shaft 50 jointly act to realize gas-liquid separation of the mixed-state refrigerant.
In the operation process of the fluid machine, the mixed state refrigerant enters the separation cavity 411 and rotates along with the rotating shaft 50, and the gas and the liquid in the mixed state refrigerant are separated in the separation cavity 411 due to different centrifugal acting forces of the gas and the liquid, and the separated gas enters the cylinder 30 to supply air for the cylinder 30, so that the air suction, compression and exhaust of the fluid machine are realized, and the normal operation of the fluid machine is ensured. Compared with the prior art that the gas-liquid separator of the fluid machine is arranged outside the fluid machine and is easy to influence and transfer the vibration of the fluid machine, the fluid machine in the embodiment realizes the combination of the gas-liquid separator and the gas-liquid separator, and utilizes the rotary motion of the rotary shaft 50 to perform the gas-liquid separation of the mixed state refrigerant, thereby reducing the vibration source and the noise source, reducing the vibration and the noise in the operation process of the fluid machine and improving the use experience of users.
In the embodiment, the gas-liquid separator is not arranged in the fluid machine, but the gas-liquid separation assembly is arranged in the fluid machine to perform gas-liquid separation on the mixed-state refrigerant, so that noise sources and vibration sources of the fluid machine are reduced, and vibration noise and unbalance of the fluid machine are reduced.
As shown in fig. 1, the fluid machine further includes a housing 100, and the rotating shaft 50, the gas-liquid separation assembly, and the air cylinder 30 are all disposed in the housing 100, and the gas-liquid separated liquid flows into the bottom of the housing 100. The housing 100 is covered outside the rotation shaft 50, the gas-liquid separation assembly and the cylinder 30 to protect the above-mentioned structure and prevent foreign matters such as dust from entering the above-mentioned structure to affect the normal operation of the fluid machine. The structure is simple and easy to assemble and realize.
Specifically, in the process of gas-liquid separation of the mixed refrigerant in the separation chamber 411, the separated liquid flows into the bottom of the housing 100 under the action of self weight, so that the normal operation of the fluid machine is not affected. Meanwhile, the liquid flowing into the bottom of the housing 100 can be gasified in the fluid machine, and the gasified refrigerant can enter the cylinder 30 to supply air to the cylinder 30.
As shown in fig. 1 and 2, the gas-liquid separation assembly is located below the cylinder 30. Like this, the gas after the separation is because the density is less, natural upward movement sets up cylinder 30 in the top of gas-liquid separation subassembly for it is easier that the gas gets into cylinder 30 after the separation, does not need to increase extra pipeline and guides gas, and then makes fluid machinery inner structure simpler, reduces fluid machinery's processing cost. Meanwhile, the separated liquid moves downwards under the action of the dead weight of the liquid, and the position of the air cylinder 30 is set to prevent the liquid from entering the air cylinder 30, so that the normal operation of the fluid machinery is ensured.
As shown in fig. 1, 2 and 11, the fluid machine further comprises a filter element 60, the filter 60 is sleeved outside the rotating shaft 50, and the filter 60 is located at a position where the separation chamber 411 communicates with the cylinder 30. Thus, the above arrangement makes the gas-liquid separation effect in the separation chamber 411 better, and improves the working performance of the fluid machine.
Specifically, when the rotation shaft 50 rotates and the filter element 60 rotates along with the rotation shaft 50, the filter element 60 further plays a role in separating gas from liquid when the mixed refrigerant passes through the filter element 60, and the liquid in the mixed refrigerant is easily thrown out by the filter element 60 under the action of the centrifugal force of the filter element 60. In this way, the filter 60 can prevent the liquid from passing through, and further ensure that all the liquid entering the cylinder 30 is gas, and the liquid enters the bottom of the housing 100, thereby further improving the working reliability of the fluid machine.
As shown in fig. 1, 2 and 10, the rotary shaft 50 includes a main body 52 and a rotor portion 51. Wherein the rotor portion 51 is eccentrically disposed on the body 52. The rotor portion 51 is located in the cylinder 30, at least a portion of the body 52 is located in the separation chamber 411, and the filter 60 is sleeved outside the body 52. The structure is simple and easy to process and assemble.
Specifically, the motor 80 drives the rotating shaft 50 to rotate, the rotor portion 51 is sleeved with the roller 90, and the roller 90 rotates in the cylinder 30, so as to realize air suction, compression and air discharge of the cylinder 30. The filter 60 is sleeved on a part of the body 52, and the mixed refrigerant is subjected to gas-liquid separation under the action of the body 52 along with the rotation of the body 52, the separated gas enters the cylinder 30 through the filter 60, and the separated liquid cannot pass through the filter 60 and flow into the bottom of the shell 100.
As shown in fig. 1 and 10, the body 52 has a variable-diameter enlarged section 521, the variable-diameter enlarged section 521 is located in the separation chamber 411, and the filter 60 is sleeved outside the variable-diameter enlarged section 521. Thus, the above arrangement can increase the contact area between the main body 52 and the mixed state refrigerant, and improve the gas-liquid separation efficiency; on the other hand, the above arrangement can reduce the volume of the filter element 60, thereby reducing the quality of the filter element 60, ensuring that the arrangement of the filter element 60 does not affect the normal operation of the rotating shaft 50, and improving the working performance and the working reliability of the fluid machine.
Alternatively, the filter 60 may be one or more layers of filter mesh, and when the filter is a plurality of layers, the layers of filter mesh are disposed at intervals along the axial direction of the body 52. As shown in fig. 2, in the present embodiment, the filter mesh has a two-layer structure, and the two layers of filter mesh are disposed at intervals along the axial direction of the body 52. In this way, the above arrangement can further improve the filtration efficiency of the filter 60, preventing the gas-liquid mixture from entering the cylinder 30.
As shown in fig. 1 to 3, the fluid machine further includes a partition 20. Wherein the separator 20 is located between the cylinder 30 and the gas-liquid separation module, the separator 20 has a communication hole 21 communicating with the separation chamber 411, and the separated gas enters into the cylinder 30 through the communication hole 21. The fluid machine further comprises an upper flange 10, the air cylinder 30 is positioned between the upper flange 10 and the partition plate 20, the gas-liquid separation assembly is positioned below the partition plate 20, and separated gas enters the air cylinder 30 through the communication hole 21 on the partition plate 20 to supply air for the air cylinder 30, so that the air suction, compression and exhaust actions of the air cylinder 30 are realized. The fluid machine is divided into an upper part and a lower part by the partition plate 20, the lower part is used for gas-liquid separation, and the upper part is used for air suction, compression and air discharge, so that the structural layout of the fluid machine is more compact and reasonable.
As shown in fig. 3, 5 to 7, the cylinder 30 has an intake passage 31 and a communication passage 311 that communicate with the communication hole 21 in order, the extending direction of the intake passage 31 is provided in the axial direction of the cylinder 30, and the extending direction of the communication passage 311 is provided in the radial direction of the cylinder 30 and penetrates to the inner chamber 32 of the cylinder 30. Specifically, the gas separated in the separation chamber 411 passes through the communication hole 21 and then enters the gas inlet passage 31 of the cylinder 30, passes through the gas inlet passage 31 and enters the communication passage 311, and finally enters the inner chamber 32 of the cylinder 30 to be supplied to the cylinder 30. The structure is simple and easy to realize.
Note that the structural arrangement of the intake passage 31 is not limited thereto. Alternatively, a through hole of the intake passage 31 is provided on a wall of the through hole with a communication passage 311 penetrating to the inner chamber 32 of the cylinder 30. The structure makes the processing of the air inlet channel 31 easier and simpler, thereby reducing the labor intensity of staff and shortening the processing time.
Alternatively, the intake passage 31 and the communication passage 311 are provided near the vane groove 33 of the cylinder 30.
As shown in fig. 1 to 3, the gas-liquid separation assembly includes a separation structure 41 and a liquid storage structure 42. Wherein the separation structure 41 is located below the partition 20, the separation structure 41 having a separation chamber 411. The liquid storage structure 42 is provided with a liquid inlet through hole 421 communicated with the separation cavity 411, the separation structure 41 is positioned between the partition plate 20 and the liquid storage structure 42, and separated liquid enters the liquid storage structure 42 through the liquid inlet through hole 421. Specifically, the mixed refrigerant entering the separation structure 41 performs gas-liquid separation in the separation chamber 411 of the separation structure 41, the separated gas enters the cylinder 30 through the communication hole 21 communicated with the separation chamber 411, and the separated liquid enters the liquid storage structure 42 through the liquid inlet through hole 421 communicated with the separation chamber 411, so as to prevent the separated liquid from affecting the gas-liquid separation in the separation chamber 411. The structure is simple and easy to assemble.
As shown in fig. 8 and 9, the liquid storage structure 42 has a through hole 422 through which the rotating shaft 50 passes and a storage chamber 423 for storing the separated liquid, and the liquid inlet through hole 421 communicates with the storage chamber 423. In this way, the reservoir structure 42 acts as a lower flange, ensuring that the shaft 50 can rotate about its central axis.
Specifically, the rotating shaft 50 penetrates into the liquid storage structure 42 through the through hole 422 on the liquid storage structure 42, and the liquid in the storage cavity 423 does not contact with the rotating shaft 50. During operation of the fluid machine, the internal temperature of the fluid machine is high, and the liquid in the storage chamber 423 is gasified and then enters the cylinder 30 through the separation chamber 411.
It should be noted that the volume of the storage chamber 423 may be designed to be different sizes to meet the fluid mechanical requirements of different displacements.
As shown in fig. 1, the compressor further includes a cover 70 located below the liquid storage structure 42, wherein an end of the storage cavity 423 facing the cover 70 is an open end, and the storage cavity 423 and the cover 70 form a closed space to store separated liquid. Thus, when more liquid is stored in the storage chamber 423, the cover 70 may be removed from the lower end to release the liquid in the storage chamber 423 to the bottom of the housing 100.
Specifically, the fastening member sequentially passes through the upper flange 10, the air cylinder 30, the partition 20, the separation structure 41 and the liquid storage structure 42 and then is fixed on the cover 70, so that the above structures are fastened and connected together, the tightness of the separation cavity 411 and the inner cavity 32 of the air cylinder 30 is ensured, and the internal structure of the fluid machine is more compact.
Optionally, the fastener is a bolt. The bolts are standard components, so that the processing cost of the fluid machinery can be reduced.
As shown in fig. 4, the separation structure 41 includes a liquid inlet passage 412 and a gas outlet passage 413. The liquid inlet channel 412 extends along a direction perpendicular to the rotation shaft 50 and is in communication with the separation chamber 411. The gas outlet passage 413 communicates with both the separation chamber 411 and the communication hole 21 to introduce the separated gas into the communication hole 21. In this way, the separation structure 41 adopts the internal flow channel structure form, so that components can be saved, pipeline connection can be simplified, and the problems of arrangement, occupied size of an external pipeline, deformation caused by welding of the external pipeline and the like are avoided.
Specifically, the mixed refrigerant enters the separation chamber 411 through the liquid inlet channel 412, after the gas-liquid separation in the separation chamber 411, the gas enters the communication hole 21 through the gas outlet channel 413, and then enters the cylinder 30 through the communication hole 21, so as to realize the air suction, compression and exhaust in the cylinder 30.
As shown in fig. 2, the distance H1 between the fluid inlet channel 412 and the fluid reservoir structure 42 is less than or equal to the distance H2 between the filter element 60 and the fluid reservoir structure 42. In this way, the above arrangement ensures that the mixed refrigerant can smoothly enter the separation chamber 411 through the liquid inlet channel 412, and prevents the filter 60 during rotation from affecting the normal liquid inlet of the liquid inlet channel 412.
As shown in fig. 4, the air outlet passage 413 includes a transition groove 413a and an air outlet groove 413b. Wherein the transition groove 413a is located on the chamber wall of the separation chamber 411. The air outlet groove 413b is located on the end face of the separation structure 41 facing the partition plate 20, and the air outlet groove 413b communicates the transition groove 413a with the communication hole 21. Specifically, the separator 20 is disposed above the separation structure 41 and is disposed in close contact with the separation structure 41, so that the flow of the separated gas from the separation chamber 411 into the communication hole 21 is easier, and the gas flow smoothness is improved without occurrence of vortex or the like.
