[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Reference Figure 1 and Figure 3 , the air compressor provided by the utility model is now described.

The flow guide system 2 includes a drive mechanism 21, an adjustment mechanism 22, and guide vanes 23 disposed on the air intake duct 1. The adjustment mechanism 22 is sleeved on the air intake duct 1, and the guide vanes 23 are rotatably connected to the wall of the air intake duct 1. The adjustment member 222 is mechanically disposed between the drive mechanism 21 and the guide vanes 23 and is connected to both. The drive mechanism 21 is used to drive the adjustment mechanism 22 to rotate, and the adjustment mechanism 22 drives the guide vanes 23 to rotate as it rotates.

[0036] Compared with the prior art, the air compressor provided by the present invention has a flow guide system 2 provided on the air intake duct 1 to adjust the flow direction of the air intake airflow of the air compressor during operation, thereby reducing the turbulence in the air intake airflow of the air compressor and further reducing the negative impact of the turbulence on the air compressor. When adjusting the flow direction of the air intake airflow, the driving mechanism 21 drives the regulating mechanism 22 to rotate, and the regulating mechanism 22 drives the guide vanes 23 to rotate when rotating. The flow guide system 2 adjusts the size and direction of the recent airflow by adjusting the angle of the guide vanes 23, thereby reducing the turbulence in the airflow. At the same time, when the flow guide system 2 adjusts the angle of the guide vanes 23, the surge line of the air compressor moves to the left. Therefore, under normal working conditions, the guide vanes 23 are fully open and consistent with the direction of the airflow. When the working conditions are close to the surge zone or in the surge zone, the guide vanes 23 are adjusted by the flow guide system 2 to adjust the rotation angle so that the air inlet is closed, the intake flow is reduced, and the surge line moves to the left to meet the working conditions.

[0037] Optionally, the adjustment mechanism 22 includes an adjustment ring 221 sleeved on the air intake duct 1 and an adjustment member 222. The adjustment ring 221 is connected to the driving mechanism 21. The driving mechanism 21 can drive the adjustment ring 221 to rotate around the outer peripheral wall of the air intake duct 1. The adjustment member 222 is slidably connected to the adjustment ring 221.

[0038] Optionally, a guide member 223 is provided on the side of the adjustment ring 221, and a slide groove is provided on the guide member 223. A cylindrical slider is provided at the end of the adjustment member 222. The slider is disposed in the slide groove. The adjustment member 222 is connected to the guide member 223 through the engagement of the slider and the slide groove. When the drive mechanism 21 drives the adjustment ring 221 to rotate, the adjustment ring 221 drives the adjustment member 222 to rotate. The adjustment member 222 and the adjustment ring 221 simultaneously slide and rotate relative to each other.

[0039] Optionally, the guide vane 23 is provided with a rotating shaft 231. A mounting hole is provided in the wall of the intake duct 1, and the rotating shaft 231 is mounted in the mounting hole so that the rotating shaft 231 can rotate within the mounting hole. One end of the rotating shaft 231 extends through the mounting hole and is exposed to the outside of the intake duct 1. The adjusting member 222 is fixedly connected to the rotating shaft 231.

[0040] Optionally, multiple guide vanes 23 are provided, each in a fan-shaped configuration. The rotating shaft 231 is disposed at the center of the curved surface of the guide vane 23. After the guide vane 23 is installed, the tip of the guide vane 23 coincides with the center of the intake duct 1. All guide vanes 23 may form a disc.

[0041] Optionally, the number of the chute and the adjusting members 222 is the same as the number of the guide vanes 23. When the driving mechanism 21 drives the adjusting ring 221 to rotate, the adjusting ring 221 drives the guide vanes 23 to rotate synchronously through the adjusting members 222.

[0042] Optionally, the drive mechanism 21 includes a cylinder 211 connected to the air intake pipe 1 and a connector 212.

One end of the connector 212 is hinged to the piston rod of the cylinder 211, and the other end is hinged to the adjustment ring 221.

[0043] When the piston rod of the cylinder 211 moves, the connecting member 212 moves with the piston rod of the cylinder 211 and simultaneously drives the adjustment ring 221 to rotate. When the adjustment ring 221 rotates, the rotating shaft 231 of each guide vane 23 is synchronously driven to rotate through each adjustment member 222, thereby synchronously adjusting the angle of the guide vane 23.

[0044] Optionally, the air compressor provided in this embodiment further includes an air outlet pipe 3. The cylinder 211 is connected to the air outlet pipe 3 through a pipe. The cylinder 211 uses the air outlet end of the air compressor as an air source, and there is no need to set up a separate air source for the cylinder 211, thereby simplifying the structure.

When adjusting the flow direction of the air intake airflow, the driving mechanism 21 drives the regulating mechanism 22 to rotate, and the regulating mechanism 22 drives the guide vanes 23 to rotate when rotating. The flow guide system 2 adjusts the size and direction of the recent airflow by adjusting the angle of the guide vanes 23, thereby reducing the turbulence in the airflow. At the same time, when the flow guide system 2 adjusts the angle of the guide vanes 23, the surge line of the air compressor moves to the left. Therefore, under normal working conditions, the guide vanes 23 are fully open and consistent with the direction of the airflow. When the working conditions are close to the surge zone or in the surge zone, the guide vanes 23 are adjusted by the flow guide system 2 to adjust the rotation angle so that the air inlet is closed, the intake flow is reduced, and the surge line moves to the left to meet the working conditions.

[0056] Electronic actuators are an essential component of automation systems. Their primary function is to receive control signals from the controller and change the size of the controlled medium, thereby maintaining the controlled variable at the desired value or within a certain range. Electronic actuators can be divided into three categories based on their energy source: pneumatic, hydraulic, and electric. In automation systems, electronic actuators are responsible for converting control signals into actual actions. Depending on the signal type, electronic actuators can be divided into two types: digital actuators and analog actuators. Digital actuators are primarily used to control systems with only two states, such as open or closed, while analog actuators can receive and respond to continuously changing signals, such as 4-20mA current signals, to precisely control the actuator's opening and implement complex functions such as PID control.
