[0029] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0030] Reference below Figure 1-Figure 6 A compressor assembly 100 according to an embodiment of the present application is described.

[0031] According to the compressor assembly 100 of the embodiment of the present application, it includes a compressor housing 1, an impeller 2 and an adjusting blade 3. A compression chamber 11 and an air intake passage 12 connected to the compression chamber 11 are formed inside the compressor housing 1. The impeller 2 is rotatably arranged in the compression chamber 11. The adjusting blade 3 is rotatably arranged in the air intake passage 12 to adjust the air intake amount of the air intake passage 12. The rotating axis 32 of the adjusting blade 3 is orthogonal to the extension direction of the air intake passage 12; wherein an air guide passage 31 is formed on the adjusting blade 3.

[0032] According to the compressor assembly 100 of the embodiment of the present application, the impeller 2 provides power for the transmission of the fluid in the intake channel 12, and the compressor housing 1 provides physical protection for various internal components. In the process of the airflow entering the compression chamber 11 through the air guide channel 31, since the fluid in the air guide channel 31 flows toward the compression chamber 11, a boundary layer will be generated on the regulating blades 3 around the air guide channel 31. The boundary layer is a thin fluid layer tightly attached to the surface of the regulating blades 3. The fluid speed inside the boundary layer gradually transitions from zero speed on the surface of the regulating blades 3 to the speed of the fluid in the air guide channel 31. When the fluid passes through the air guide channel 31, the fluid on the surface of the boundary layer is continuously sucked away by the fluid in the air guide channel 31, and the fluid inside the boundary layer that originally tends to stagnate and flow slowly is continuously transitioned to the surface of the boundary layer, prompting the fluid in the boundary layer to be continuously renewed, thereby increasing the flow rate of the fluid through the guide channel and optimizing the flow path of the fluid in the intake channel 12.

[0033] During the air intake process of the compressor, the air intake angle and angle of attack of the airflow will affect the smoothness of the airflow entering the compression chamber 11 through the regulating blade 3. The intake angle is the inflow angle of the airflow relative to the regulating blade 3, and the angle of attack is the angle between the airflow direction and the extension direction of the regulating blade 3. When the two angles are in a suitable range, the airflow can flow along the surface of the regulating blade 3 and enter the compression chamber 11. Because the opening range of the regulating blade 3 is small under low flow conditions, there is a situation where the intake angle is too large or the angle of attack is too large, the airflow will be turbulent on the surface of the regulating blade 3, and airflow separation will occur. The airflow will generate abnormal flow states such as vortex and backflow in the intake channel 12, which will increase the intake resistance and make the fluid flow and pressure entering the compressor unstable, causing surge. By setting an air guide channel 31 on the regulating blade 3, an additional flow channel is provided for the circulation of the fluid, ensuring that the fluid can enter the compression chamber 11 through the air guide channel 31, avoiding the airflow separation caused by angle problems, and improving the operating stability of the compressor assembly 100.

[0034] In short, an air guide channel 31 is formed on the adjusting blade 3. When the compressor is in a low flow condition, the air guide channel 31 provides an additional flow path for the gas, and the gas can smoothly enter the compression chamber 11, so that when the flow rate of the intake channel 12 is small, a relatively stable proportional relationship between the axial velocity and the circumferential velocity of the airflow can still be maintained, and the gas will not cause a sharp decrease in the axial velocity due to a slight change in the flow rate of the intake channel 12, thereby avoiding the situation where the reduction rate of the axial velocity is greater than the reduction rate of the circumferential velocity, and can effectively prevent the occurrence of surge. The flow rate and intake pressure of the intake channel 12 are stabilized, avoiding backflow and the loud noise and strong vibration of the multi-stage compressor unit due to unstable intake pressure, thereby improving the stability of the compressor under low flow conditions, ensuring the normal operation and structural safety of the compressor, extending the service life of the compressor assembly 100, and reducing the maintenance cost and operation risk caused by surge.

[0035] According to the compressor assembly 100 of some embodiments of the present application, the regulating blade 3 is constructed as a sheet extending in a direction close to the center of the air intake channel 12, and the air guide channel 31 passes through at least two edges of the regulating blade 3 and is consistent with the extension direction of the regulating blade 3.

[0036] The regulating blade 3 is constructed in a sheet shape, and the sheet structure has a small windward area. When adjusting the intake volume, it can relatively accurately change the flow state of the airflow, and its own obstruction to the airflow is relatively controllable, and will not cause additional airflow turbulence due to the overly complex shape. At the same time, the sheet-shaped regulating blade 3 is easy to process and manufacture, and the cost is relatively easier to control, which is convenient for large-scale application in the actual production of the compressor assembly 100. The regulating blade 3 extends toward the center of the intake channel 12, because the airflow in the intake channel 12 may have different flow velocities and pressure distributions at different positions, and the regulating blade 3 extending toward the center can cover a wider area, so that no matter whether the airflow is close to the channel wall or in the center of the channel, it can be affected by the regulating blade 3. When adjusting the intake volume, it can change its own angle by rotating and other methods according to the actual operating conditions of the compressor, and reasonably guide the airflow from different positions, so that the airflow enters the subsequent compression chamber 11 more orderly, thereby ensuring the stability and uniformity of the entire intake process.

[0037] Furthermore, the air guide channel 31 passes through at least two edges of the regulating blade 3. When the airflow passes through the regulating blade 3, a part of the airflow can continue to move forward through the air guide channel 31, thereby avoiding blockage or excessive disturbance of the airflow at the regulating blade 3. Moreover, the through air guide channel 31 can make the pressure and flow rate of the airflow at different positions change more continuously and smoothly when passing through the regulating blade 3, which helps to maintain the stability of the overall flow field in the air intake channel 12. Under some working conditions, the airflow velocity in the air intake channel 12 is relatively fast. If there is no through air guide channel 31, the airflow impacting the regulating blade 3 may generate a large pressure fluctuation. However, with the through air guide channel 31, , the airflow can be diverted and transitioned through it, reducing the generation of such pressure fluctuations; the air guide channel 31 is consistent with the extension direction of the regulating blade 3, so that the airflow can pass through the air guide channel 31 more smoothly along the overall direction of the regulating blade 3, reducing the airflow separation, vortex and other adverse flow phenomena caused by inconsistent directions, and further optimizing the fluid flow conditions at the air intake. When the regulating blade 3 rotates according to operating requirements, the air guide channel 31 consistent with the extension direction can still cooperate well with the angle change of the regulating blade 3, and continue to play a role in guiding and optimizing the airflow, in order to avoid surge and improve the stability of the compressor under low flow conditions.

[0038] According to the compressor assembly 100 of some embodiments of the present application, the adjusting blade 3 is constructed to be a plurality of adjusting blades 3 arranged at intervals along the circumferential direction in the air intake passage 12, the rotating axis 32 of each adjusting blade 3 extends radially along the air intake passage 12 or extends inclined relative to the radial direction, and each adjusting blade 3 is provided with an air guide channel 31 between the two side edges in the circumferential direction.

[0039] A plurality of regulating blades 3 are arranged at intervals along the circumferential direction in the air intake channel 12, which can achieve relatively comprehensive and uniform regulation of the airflow in the entire circumferential direction in the air intake channel 12, so that the airflow in the entire air intake channel 12 tends to be uniform and stable in the circumferential direction, providing a good initial state for the subsequent airflow entering the compression chamber 11.

[0040] When the rotating shaft 32 of the adjusting blade 3 extends along the radial direction of the air inlet passage 12, the adjusting blade 3 can directly and effectively adjust the airflow at different radial positions in the air inlet passage 12 with the radial direction as the axis when rotating. The adjusting blade 3 can change the angle between itself and the airflow by rotating around the radial rotating shaft 32, thereby changing the effective area and flow direction of the airflow. When the air intake volume needs to be reduced, the adjusting blade 3 rotates clockwise or counterclockwise around the radial rotating shaft 32 at a certain angle, so that the passage through which the airflow passes becomes narrower, thereby achieving control of the air intake volume. When the rotating shaft 32 of the adjusting blade 3 extends obliquely relative to the radial direction, the obliquely extended rotating shaft 32 makes the adjusting blade 3 change the angle of action on the airflow during the rotation process. The flow field in the air inlet passage 12 can be further optimized at different radial and circumferential positions. For some situations where there may be local airflow turbulence, the adjusting blade 3 with the obliquely extended rotating shaft 32 can improve the airflow condition in the local area in a targeted manner by rotating at a specific angle, so that the airflow in the entire air inlet passage 12 is more stable and orderly.

[0041] Each regulating blade 3 is provided with an air guide channel 31 between the two side edges in the circumferential direction, providing an additional flow path for the airflow. In the air intake channel 12, when the airflow flows along the air intake channel 12, it may encounter certain obstructions or pressure changes when encountering the regulating blade 3, but the air guide channel 31 allows part of the airflow to pass between the two side edges in the circumferential direction of the regulating blade 3, thereby alleviating the pressure difference of the airflow when it flows in the circumferential direction, avoiding local vortex, backflow and other unfavorable flow phenomena caused by the obstruction of the circumferential airflow, reducing the occurrence rate of surge phenomenon, and improving the stability of the operation of the compressor assembly 100.

[0042] According to some embodiments of the compressor assembly 100 of the present application, the outer edge of the regulating blade 3 is constructed as an outer arc segment 33, the outer arc end protrudes away from the center of the intake passage 12, and the inner edge of the regulating blade 3 is constructed as an inner arc segment 34 and is recessed away from the center of the intake passage 12.

[0043] The outer arc section 33 of the regulating blade 3 is convex away from the center of the air intake channel 12, so that when multiple regulating blades 3 are arranged at intervals in the circumferential direction of the air intake channel 12, they match the cross-section of the air intake channel 12, and can perform relatively comprehensive and uniform regulation of the airflow in the entire circumferential direction of the air intake channel 12, so as to avoid the loss of the flow control function of the regulating blade 3 due to size mismatch; and the inner arc section 34 of the inner edge of the regulating blade 3 is concave away from the center of the air intake channel 12, so that a channel is reserved in the center of the air intake channel 12 after the multiple regulating blades 3 are combined. When the airflow enters the air intake channel 12, the central channel can provide a path for part of the airflow to directly lead to the compression chamber 11. The central channel can enable part of the airflow to quickly reach the compression chamber 11 with relatively low resistance, which is helpful to quickly establish a stable compression cycle. For airflows with different flow rates and pressures, the central channel can play a role of diversion and buffering. High-speed airflow can pass quickly through the central channel, while low-speed airflow can interact with the regulating blades 3 in the peripheral area before entering the compression chamber 11, thereby optimizing the airflow distribution in the entire air intake process and improving the air intake efficiency and stability.

[0044] According to the compressor assembly 100 of some embodiments of the present application, the air guide passage 31 is configured as an arc-shaped passage that is concave in the arc shape away from the center of the air intake passage 12 .

[0045] The air guide channel 31 is constructed as an arc-shaped channel that is recessed away from the center of the air intake channel 12. From the cross-section of the air intake channel 12, the air guide channel 31 presents an arc-shaped shape that is recessed away from the center. When the air flow passes through the air guide channel 31, since the air guide channel 31 is recessed away from the center of the air intake channel 12, the air flow will converge along the arc-shaped channel toward the direction relatively closer to the edge of the adjustment blade 3 and closer to the wall of the air intake channel 12. The originally dispersed air flow will be gradually gathered after flowing through the air guide channel 31, so that the air flow will flow more orderly when passing through the air guide channel 31, avoiding disordered diffusion or turbulent flow of the air flow after passing through the air guide channel.

[0046] According to the compressor assembly 100 of some embodiments of the present application, the air guide channel 31 is coaxially arranged with the inner arc segment 34 and the outer arc segment 33 respectively.

[0047] The air guide channel 31 is coaxial with the inner arc segment 34 and the outer arc segment 33 of the regulating blade 3. From a geometric point of view, the center of the circle of the air guide channel 31 coincides with the center of the circle of the inner arc segment 34 and the center of the circle of the outer arc segment 33. The coaxial setting avoids the additional interference to the airflow that may be caused by the incoordination between the positions of the air guide channel 31 and the inner arc segment 34 and the outer arc segment 33. If the air guide channel 31 is not coaxial with the inner arc segment 34 and the outer arc segment 33, when the airflow passes through the regulating blade 3 and the air guide channel 31, the flow directions of multiple airflows are not unified, resulting in unstable factors such as vortices and local pressure mutations in the flow field. The coaxial setting makes the flow of the airflow conform to the unified and coordinated laws, and the various parts in the flow field can cooperate with each other, reducing the generation of these interference factors, thereby maintaining the relative stability of the flow field in the intake channel 12, which is crucial to preventing the occurrence of surge and ensuring the stable operation of the compressor under different working conditions.

[0048] According to the compressor assembly 100 of some embodiments of the present application, the thickness of the regulating blade 3 is D, the maximum height of the air guide channel 31 is d, and the following condition is satisfied: 1 / 4≤d / D≤3 / 4.

[0049] When d / D≤1 / 4, the air guide channel 31 may be too narrow. In this case, although the strength of the regulating blade 3 itself may be relatively high, the regulating effect of the air guide channel 31 on the airflow will be limited, because the narrow channel cannot effectively guide a sufficient amount of airflow to pass through, especially under conditions where a large amount of air intake is required, which may lead to low air intake efficiency; when d / D≥3 / 4, the air guide channel 31 is too high, which will affect the structural strength of the regulating blade 3. The regulating blade 3 may be easily deformed when it is subjected to the airflow pressure and the force of its own rotation. Moreover, the excessively high air guide channel 31 may change the flow field structure around the regulating blade 3, causing abnormal pressure changes and flow separation of the airflow near the channel, which is not conducive to the stability of the air intake.

[0050] According to the compressor assembly 100 of some embodiments of the present application, the distance between the inner arc segment 34 and the outer arc segment 33 is L, the maximum width of the air guide channel 31 in the radial direction is l, and satisfies: 1 / 10≤l / L≤1 / 3.

[0051] When l / L≤1 / 10, the air guide channel 31 is too narrow in the radial direction. The narrow air guide channel 31 is difficult to be reasonably arranged in the adjusting blade 3, and the processing and manufacturing will also face the problem of too high precision requirements. Moreover, since the channel is too narrow, its regulating effect on the airflow may not be fully exerted, and it is difficult to meet the needs of effective regulation of the intake volume and airflow state under different working conditions; when l / L≥1 / 3, the space occupied by the air guide channel 31 in the radial direction is too large, which will disrupt the reasonable distribution of the space between the inner arc segment 34 and the outer arc segment 33 of the adjusting blade 3, resulting in the structural strength of the adjusting blade 3 being affected, because the part left for maintaining the stability of the blade structure is relatively reduced, and the excessive width of the air guide channel 31 may make the overall layout of the adjusting blade 3 in the air intake channel 12 appear inconsistent, changing the originally expected path and state of the airflow when flowing through the adjusting blade 3, and easily causing abnormal pressure distribution and flow turbulence of the airflow around the channel.

[0052] According to the compressor assembly 100 of some embodiments of the present application, the cross-section of the air guide channel 31 is configured as an oblong hole.

[0053] When the airflow enters the air guide channel 31, the curved boundary of the oblong hole can achieve a smooth transition of the airflow. Compared with the sharp corners of the rectangle, the shape of the oblong hole does not have a sudden change of direction, thereby effectively reducing the separation of the airflow caused by the sharp turn at the inlet. Under the condition of small flow of the compressor, the airflow speed is relatively low and more sensitive. The soft curve of the oblong hole can make the airflow smoothly converge from the air intake channel 12 and enter the air guide channel 31, avoiding the pressure loss and unstable flow caused by airflow separation, and maintaining the stability of the air intake; compared with the circle, the long axis and short axis lengths of the oblong hole are different, which makes the oblong hole have different constraints on the airflow in different directions. Compared with the more uniform constraints of the circular channel, the oblong hole can allow relatively more airflow to pass in the long axis direction according to the compressor intake demand and airflow characteristics, and provide appropriate restrictions in the short axis direction to guide the airflow to form a specific flow pattern. Under high flow conditions, the long axis direction can adapt to a larger airflow and improve the intake efficiency, while the constraint in the short axis direction can ensure that the airflow is not too dispersed, which helps to maintain the concentration and stability of the airflow and reduce the probability of surge.

[0054] like Figure 5-Figure 6 As shown, Figure 5 is a streamline diagram of a plurality of regulating blades 3 in the air inlet channel 12 without a guide channel, Figure 6 1 is a streamline diagram of a plurality of regulating blades 3 provided with a guide channel in an air intake channel 12. It should be noted that: Figure 5 and Figure 6 It is a streamline comparison diagram of the regulating blade 3 with and without the guide channel when the opening of the regulating blade 3 is the same and the compressor is in the same working condition. Figure 5 and Figure 6 The air intake direction is from left to right. Figure 5 In FIG. 1 , it can be seen that there is a backflow to the inlet of the air inlet passage 12 on the right side of the guide vane, while Figure 6 There is no obvious backflow on the right side of the middle guide vane.
