Description

Technical Field

[0001] This utility model relates to the field of automation control, and more specifically, to a novel surge suppression device. Background Technology

[0002] Surge is a typical aerodynamic instability problem in the compression system of aero-engines, gas turbines, and turbochargers. It manifests as low-frequency large-amplitude oscillations and periodic backflow of airflow. It can lead to not only equipment performance degradation and energy waste, but also catastrophic consequences such as structural vibration, component ablation, and even complete machine damage. It seriously restricts the safety and reliability of equipment in key fields such as aviation, energy, and automobiles.

[0003] Traditional devices often rely on preset thresholds to trigger backflow or venting. The control logic is passive and the response is lagging, often resulting in energy waste due to over-adjustment. Furthermore, they cannot adaptively match the replenishment volume according to changes in pipeline pressure, making it difficult to quickly and accurately suppress surge. Most devices lack effective anti-backflow design, and the airflow is prone to backflow in the pipeline, forming vortex impacts, which aggravates blade wear and deteriorates aerodynamic performance.

[0004] A search revealed Chinese Patent Publication No. CN222296547U, which discloses a centrifugal fan surge suppression device connected to a variable frequency magnetic levitation centrifugal blower and a vertical shaft furnace; the outlet of the variable frequency magnetic levitation centrifugal blower is connected to the inlet of the vertical shaft furnace via a pipeline; the device includes: an electric regulating valve, a bypass pipe, an air volume detector, and a display; a bypass pipe is installed on the pipeline connecting the outlet of the variable frequency magnetic levitation centrifugal blower and the inlet of the vertical shaft furnace; an electric regulating valve is installed on the bypass pipe; the air volume detector is installed at the inlet of the variable frequency magnetic levitation centrifugal blower; the air volume detector is electrically connected to the display. This device, combined with the high-speed operation characteristics of magnetic levitation fans, can effectively avoid surge during the low-fire preheating stage of vertical furnaces without increasing pipeline resistance and maintaining the existing constant pressure frequency conversion control mode of the fans. However, this utility model does not provide targeted protection for equipment and pipeline vibration. The high-frequency vibration during compressor operation can easily cause damage or malfunction of key accessories of the anti-surge valve positioner, or even cause the unit to trip, seriously affecting the operational stability and equipment life.

[0005] Therefore, we have made improvements to this and proposed a new surge suppression device. Utility Model Content

[0041] Furthermore, such as Figure 1 , Figure 2 , Figure 3As shown, a connecting column 12 is fixedly connected to the bottom of the push chamber 11, a push-pull plate 13 is fixedly connected to the bottom of the connecting column 12, a sealing ring 16 is fixedly connected to the bottom of the inner wall of the fixing plate 4, and a connecting seat 17 is slidably connected to the inner wall of the sealing ring 16.

[0042] Example 2

[0043] The novel surge suppression device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the anti-backflow mechanism 2 includes a dredging pipe 201. The outer wall of the dredging pipe 201 is located at the bottom of the supplementary pipe 1. A connecting arm 202 is fixedly connected to the inner left side of the dredging pipe 201. A fixing arm 203 is fixedly connected to the outer wall of the connecting arm 202. A circulation plate 204 is fixedly connected to the outer wall of the fixing arm 203.

[0045] The usage process of the novel surge suppression device provided by this utility model is as follows:

[0046] During operation, a fixing plate 4 is fixed inside the replenishment pipe 1. When the pressure in the unblocking pipe 201 decreases, the pressure difference between the replenishment pipe 1 and the unblocking pipe 201 causes the push chamber 11 to be pulled downward by the connecting column 2 12. There is a connecting groove 10 on the top of the outer wall of the push chamber 11, which drives the connecting column 1 9 to move. Under the pull of the connecting column 1 9, one side of the rotating plate 6 rotates around the connecting shaft 7, which increases the inclination of the outer wall of the rotating plate 6 and the flow groove 5, thereby increasing the air pressure replenished from the replenishment pipe 1 and thus preventing surge.

[0047] Inside the left side of the unblocking pipe 201, there is a connecting arm 202 for connection. A fixing arm 203 is connected to the middle of the connecting arm 202 for connection. A circulation plate 204 is connected to the outer wall of the connecting arm 202, so that when the raw material is passed from the left to the right, backflow can be prevented. A baffle plate 205 is also provided in the middle of the unblocking pipe 201 for assistance. A buffer ring 207 and a connecting plate 208 are provided on the outer wall of the unblocking pipe 201 to reduce the occurrence of vibration of the outer wall during conveying.
