[0036] The embodiments of this utility model will be described in detail below.
[0037] Example
[0038] See Figure 1 This embodiment provides a centrifugal air compressor testing device, including a mounting base 1, an inlet monitoring pipe 2, an air supply mechanism 3, and an outlet monitoring pipe 4.
[0039] Mounting base 1 is hollowed out, and the centrifugal air compressor to be tested is fixed by bolts and other fasteners.
[0040] One end of the intake monitoring pipe 2 is connected to the outlet of the air supply mechanism 3, and the other end is connected to the air inlet of the centrifugal air compressor; an intake temperature sensor 21, an intake humidity sensor 22 and an intake flow sensor 23 are installed on the intake monitoring pipe 2.
[0041] The gas supply mechanism 3 is used to adjust the temperature, humidity and flow rate of the gas.
[0042] The outlet monitoring pipe 4 is installed on the mounting base 1 and connected to the outlet of the centrifugal air compressor. An outlet flow sensor 41 is installed on the outlet monitoring pipe 4.
[0043] By adjusting the temperature, humidity, and flow rate of the gas supplied by the gas supply mechanism 3, different operating conditions are simulated. The outlet flow rate sensor 41 monitors the outlet flow rate of the centrifugal air compressor, reflecting its operating status. For example, after adjusting the inlet temperature and humidity, if the outlet flow rate of the centrifugal air compressor drops significantly after a period of time, the impeller of the centrifugal air compressor may have defects such as cracks. After manual inspection to confirm the existence of the defect, if it exists, a mapping relationship (correspondence relationship) is established between the corresponding inlet temperature, humidity, and operating time and the defect, and a database is created. Subsequently, after putting equipment from the same manufacturer and batch into use, the operating conditions of the equipment are monitored in real time. Based on the real-time monitoring data and the database, the future operating status and fault phenomena of the equipment are predicted, potential risks of the equipment are detected in advance, and timely handling is carried out, thereby realizing predictive maintenance, which is conducive to maintaining stable operation of the equipment and reducing maintenance difficulty (compared to reactive maintenance).
[0044] The gas supply mechanism 3 includes a gas delivery pipe 31, a direct supply pipe 32, a humidifier 33, a dehumidifier 34, a thermostat 35, and a buffer tank 36. A flow regulating valve 37 is installed on the gas delivery pipe 31. The direct supply pipe 32, humidifier 33, and dehumidifier 34 are connected in parallel between the thermostat 35 and the flow regulating valve 37. The outlet of the thermostat 35, the buffer tank 36, and the outlet monitoring pipe 4 are connected in sequence. It is understood that valves are present on the pipes containing the direct supply pipe 32, humidifier 33, and dehumidifier 34.
[0045] The intake air flow rate is adjusted by the flow regulating valve 37, the gas humidity (moisture content) is adjusted by the humidifier 33 and dehumidifier 34, and the intake air temperature is adjusted by the thermostat 35, thereby simulating different operating conditions. It is understandable that centrifugal air compressors are usually equipped with a buffer tank 36 at the intake end in actual use.
[0046] The centrifugal air compressor testing equipment also includes a gateway 51 and a processor 52. The gateway 51 is used to collect monitoring data from the inlet air temperature sensor 21, the inlet air humidity sensor 22, the inlet air flow sensor 23, and the outlet air flow sensor 41, and sends the monitoring data to the processor 52 for storage and processing, which facilitates the recording and processing of monitoring data.
[0047] The two ends of the intake monitoring pipe 2 are connected to the buffer tank 36 and the centrifugal air compressor respectively through the bellows 6. The length of the bellows 6 is adjustable, which facilitates the connection between pipes. In addition, due to the addition of the bellows 6, the diameter of the bellows 6 and the flange sizes at both ends are available in various specifications. Therefore, without replacing the intake monitoring pipe 2, centrifugal air compressors with different sizes of intake ports can be adapted by selecting bellows 6 of different specifications.
[0048] Furthermore, a bracket 7 is connected below the intake monitoring pipe 2, and the bracket 7 is installed on the mounting base 1 to ensure that the intake monitoring pipe 2 maintains a stable posture after installation. The bracket 7 is height-adjustable to facilitate adjustment of the vertical distance between the intake monitoring pipe 2 and the mounting base 1. The bracket 7 includes a support 71 and a lifting plate 72. The support 71 is slidably connected to the mounting base 1, and the lifting plate 72 is slidably connected to the upper part of the support 71. The relative sliding between the lifting plate 72 and the support 71 is limited by a screw 73. The screw 73 is threaded to one side of the support 71 and can contact the lifting plate 72. Tightening the screw 73 restricts the movement of the lifting plate 72.
[0049] Considering that centrifugal air compressors generate significant mechanical vibrations during operation, vibration reduction measures are often implemented after the centrifugal air compressors are put into use. In this embodiment, to more closely approximate the installation conditions when the centrifugal air compressor is put into use, and to make the data monitored by the centrifugal air compressor testing equipment more reliable, the centrifugal air compressor is mounted on the mounting base 1 via the vibration damping seat 11.
[0050] Finally, it should be noted that the above are merely preferred embodiments of this application and are not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
