[0023] To better understand the above technical solutions, the technical solutions of the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the embodiments of this application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0024] The first aspect of this application provides a vacuum flange assembly 10, such as Figure 1 , Figure 2 and Figure 3 As shown, the vacuum flange assembly 10 includes: a housing 100 and a flange 200. The wall of the housing 100 is provided with a plurality of vacuum ports 110, any one of which penetrates the wall of the housing 100. At least one vacuum port 110 is used to connect to a vacuum pump. The bottom wall of the housing 100 is provided with an opening. The flange 200 is connected to the bottom wall of the housing 100. The flange 200 is provided with a communication port 210, which communicates with the opening. The flange 200 is used to connect to mechanical equipment 20.

[0025] In this embodiment, the vacuum flange assembly 10 is used for the trial operation of the mechanical equipment 20, which may be a centrifugal compressor. A cavity is formed inside the housing 100, and the wall surface of the housing 100 is provided with multiple vacuum ports 110. Each vacuum port 110 is a through hole that penetrates the provided wall surface. At least one vacuum port 110 is connected to a vacuum pump, so that the vacuum pump communicates with the cavity through the vacuum port 110. The number of vacuum pumps connected is less than or equal to the number of vacuum ports 110, and the remaining unconnected vacuum ports 110 are in a blocked state.

[0026] The flange 200 is connected to the bottom wall of the housing 100 with an opening. The center of the flange 200 has a through port 210, which is connected to the cavity through the opening. The flange 200 is used to connect the mechanical equipment 20, so that the vacuum pump can be connected to the mechanical equipment 20 through the vacuum flange assembly 10, thereby performing a vacuuming operation on the mechanical equipment 20.

[0027] By setting multiple vacuum interfaces 110, the number of vacuum pumps connected to the housing 100 can be adjusted during testing of the mechanical equipment 20, thereby adjusting the number of vacuum pumps performing vacuuming operations on the mechanical equipment 20. This controls the intensity of the vacuuming operation during the test, allowing for timely adjustment of the number of vacuum pumps based on the vacuum level at the test site. This expands the vacuuming capability range during testing, prevents rework due to insufficient vacuum, improves the accuracy of vacuuming operations, and ultimately increases testing efficiency and reduces the product testing cycle. Furthermore, it expands the application range of the vacuum flange assembly 10, making it versatile and reusable, thus saving testing costs.

[0028] In some embodiments provided in this application, such as Figure 1 As shown, multiple vacuum ports 110 are distributed on different walls of the housing 100.

[0029] In this embodiment, the location of the vacuum interface 110 is defined. The vacuum interface 110 is located on different walls of the housing 100, so that the vacuum interface 110 can face different directions, which improves the flexibility of the connection position of the vacuum pump, makes it easier to arrange the position of the vacuum pump according to the actual site conditions, and expands the applicability of the vacuum flange assembly 10.

[0030] For example, any two vacuum ports 110 are located on different walls of the housing 100, making the distribution of vacuum ports 110 more dispersed, and any vacuum pump has sufficient installation space to prevent inconvenience or interference of components caused by connecting multiple vacuum pumps on the same wall.

[0031] In some embodiments provided in this application, such as Figure 1 As shown, multiple vacuum ports 110 are respectively disposed on the top wall and any side wall of the housing 100.

[0032] In this embodiment, the location of the vacuum interface 110 is further defined. Vacuum interfaces 110 are provided on all walls of the housing 100 except the bottom surface, allowing vacuum pumps to be connected in multiple directions around the outer periphery of the housing 100, further improving the flexibility of the vacuum pump connection location. Furthermore, the mechanical device 20 can connect to more vacuum pumps, increasing the maximum number of vacuum pumps that can be connected and expanding the range of vacuum operation capabilities during testing.

[0033] For example, the housing 100 is assembled from multiple metal plates, and the housing 100 can be a quadrilateral prism or a hexagonal prism. Specifically, when the housing 100 is a quadrilateral prism, the number of vacuum ports 110 is five, and the five vacuum ports 110 are located on the four sides and the top surface of the housing 100, respectively.

[0034] In some embodiments provided in this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the vacuum flange assembly 10 also includes: an end cover 300, which is detachably connected to the wall of the housing 100. The end cover 300 can cover the vacuum interface 110. The number of end covers 300 is M, and the number of vacuum interfaces 110 is N, where M = N - 1.

[0035] In this embodiment, when the mechanical device 20 performs vacuuming, it connects a corresponding number of vacuum pumps according to its model, and the remaining unused vacuum ports 110 are sealed by end caps 300. By connecting the end caps 300 to the outer wall of the housing 100, the end caps 300 cover the remaining unconnected vacuum ports 110, thereby sealing the idle vacuum ports 110. The end caps 300 form flange covers for the vacuum ports 110, ensuring the airtightness of the housing 100 during vacuuming operations.

[0036] By controlling the number of end caps 300 used, the number of vacuum ports 110 that can be sealed by the end caps 300 is controlled, thereby controlling the number of vacuum pumps that can be connected. When the housing 100 is connected to M end caps 300, one vacuum port 110 is in a connected state, allowing the mechanical device 20 to be connected to one vacuum pump. When the housing 100 is not connected to any end caps 300, N vacuum ports 110 are in a connected state, allowing the mechanical device 20 to be connected to N vacuum pumps. By limiting the number of end caps 300, the end caps 300 can cooperate with the vacuum ports 110 to perform sealing operations to the maximum extent, thus expanding the range of the number of vacuum pumps that can be connected to the mechanical device 20.

[0037] In some embodiments provided in this application, such as Figure 1 , Figure 2 and Figure 3 As shown, the outer periphery of the vacuum interface 110 is provided with a connection hole 120, which is used to connect a vacuum pump. The vacuum flange assembly 10 also includes a connector, which is connected to the end cover 300 and is detachably inserted into the connection hole 120.

[0038] In this embodiment, when the vacuum interface 110 is used with a vacuum pump, the vacuum pump can communicate with the vacuum interface 110 through the connection hole 120. When the vacuum interface 110 is used with the end cap 300, one end of the connector is connected to the end cap 300, and the other end extends into the connection hole 120 to connect to the housing 100. Through the cooperation of the connector and the connection hole 120, the end cap 300 seals the vacuum interface 110. By providing the connection hole 120 on the outer periphery of the vacuum interface 110, the connection hole 120 can be connected to both the vacuum pump and the end cap 300, improving the utilization efficiency of the connection hole 120 and simplifying the connection structure of the vacuum interface 110.

[0039] For example, there are multiple connection holes 120 surrounding the outer periphery of the vacuum interface 110, and the number of connectors is the same as the number of connection holes 120. The connectors can be bolts or screws, and the connection holes 120 can be threaded holes.

[0040] In some embodiments provided in this application, the end cap 300 is a magnetic component, and the end cap 300 is detachably connected to the housing 100 by magnetic force.

[0041] In this embodiment, the end cap 300 can be a permanent magnet or an electromagnet, the housing 100 is made of metal, the end cap 300 is detachably connected to the housing 100 by magnetic attraction, and the negative pressure environment in the cavity ensures the tightness of the end cap 300 in sealing the vacuum interface 110. This eliminates the need for parts when connecting the end cap 300, simplifies the connection structure of the end cap 300, and improves the ease of installation of the end cap 300.

[0042] Specifically, when the end cover 300 is a permanent magnet, its magnetism is low to facilitate the disassembly of the end cover 300 from the housing 100. When the end cover 300 is an electromagnet, its magnetism is controlled by switching its on / off state to achieve the disassembly of the end cover 300.

[0043] In some embodiments provided in this application, such as Figure 1 As shown, a pressure measurement interface 400 is provided on the wall of the housing 100, and the pressure measurement interface 400 penetrates the wall of the housing 100.

[0044] In this embodiment, the pressure measurement interface 400 is located on the side wall of the housing 100 and extends through the wall surface. The pressure measuring element can pass through the pressure measurement interface 400 and extend into the cavity to detect the pressure inside the housing 100. This facilitates real-time monitoring of the pressure inside the mechanical equipment 20 during the test and ensures the smooth progress of the test.

[0045] In some embodiments provided in this application, such as Figure 1 As shown, a temperature measurement interface 500 is provided on the wall of the housing 100, and the temperature measurement interface 500 penetrates the wall of the housing 100.

[0046] In this embodiment, the temperature measurement interface 500 is located on the side wall of the housing 100 and extends through the wall. The temperature measuring element can pass through the temperature measurement interface 500 and extend into the cavity to detect the temperature inside the housing 100. This facilitates real-time monitoring of the temperature inside the mechanical equipment 20 during the test and ensures the smooth progress of the test.

[0047] For example, the temperature measurement interface 500 is positioned opposite the pressure measurement interface 400.

[0048] In some embodiments provided in this application, the vacuum flange assembly 10 further includes a sealing element, wherein a sealing groove is provided on the connection surface of the end cap 300 or the housing 100, and the sealing element is located in the sealing groove.

[0049] In this embodiment, the sealing element is a sealing ring and the sealing groove is an annular groove. When the end cover 300 is connected to the housing 100, the sealing element cooperates with the sealing groove. The sealing element surrounds the outer periphery of the vacuum interface 110 to improve the airtightness of the connection between the end cover 300 and the housing 100, prevent air from entering the cavity through the gap between the end cover 300 and the housing 100, improve the sealing degree of the housing 100 during vacuuming, and ensure that the vacuuming operation is carried out smoothly.
