Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment, and more specifically, to a liquid distribution tray testing tool. Background Art

[0002] In modern heat exchange equipment, such as plate heat exchangers, absorption heat pumps, cooling water heat recovery units, large temperature difference units and other heat exchange equipment, the liquid distribution tray is generally installed above the heat exchange module to evenly spray the heat exchange medium in the gap between the plates of the heat exchange module, thereby ensuring the efficiency and stability of the entire heat exchange process.

[0003] To ensure uniform and stable distribution of heat transfer media during operation, it's necessary to monitor the distribution tray's flow. Traditional distribution tray testing methods rely heavily on manual observation and empirical judgment, which is not only inefficient but also difficult to accurately assess the performance of the distribution tray under different operating conditions. Especially under extreme operating conditions such as high flow and high pressure, manual testing methods often fail to accurately capture the flow state of the liquid within the distribution tray, leading to inaccurate test results.

[0004] In view of the above situation, the present invention proposes a liquid distribution tray testing tool. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a liquid distribution tray testing tool to solve the problems raised in the above-mentioned background technology.

[0007] It can be understood that the test fixture transports the water inside the water tank to the inside of the liquid distribution tray body, adjusts the pipeline flow through the regulating valve and variable frequency pump, observes the uniform flow and liquid fullness in the liquid distribution tray body, and records the corresponding flow if the liquid discharge condition is not good, or the liquid seeps out of the liquid distribution tray body. The liquid discharge condition and liquid fullness condition are checked manually to test the liquid distribution tray body.

[0008] In order to transport the water inside the water tank, preferably, the input and output ends of the variable frequency pump are respectively connected to the connecting steel pipe and the delivery steel pipe, wherein one end of the connecting steel pipe is connected to the water tank, and the delivery steel pipe is connected to the liquid distribution tray body.

[0009] In order to connect the liquid distribution pan body with the delivery steel pipe, preferably, a connector is provided at one end of the liquid distribution pan body, and the liquid distribution pan is threadedly connected to the delivery steel pipe through the connector, and a plurality of liquid distribution holes are evenly opened on the lower surface of the liquid distribution pan.

[0010] In order to filter the water falling into the water tank and facilitate the disassembly of the filter, preferably, a filter is installed inside the water tank, a mounting groove is provided on the surface of the water tank, a sealing plate is installed inside the mounting groove by screws, the sealing plate is connected to the filter, and a groove is provided on the surface of the sealing plate.

[0011] In order to support the filter screen, preferably, a support bar is fixedly provided on the inner wall of the water tank, and the support bar is located at the bottom of the filter screen.

[0012] Technical effects and advantages of this utility model:

[0013] 1. Use the variable frequency pump to deliver the water in the water tank to the inside of the liquid distribution tray through the connecting steel pipe and the delivery steel pipe, and use the regulating valve and variable frequency pump to adjust the pipeline flow. Observe the uniform flow and liquid fullness in the liquid distribution tray. If the liquid is not flowing well or the liquid leaks out of the liquid distribution tray, record the corresponding flow rate. Manually check the liquid flow and liquid fullness to test the liquid distribution tray, which is convenient for operators to quickly inspect.

[0014] 2. By installing a filter inside the water tank, the water discharged into the water tank during the test of the liquid distribution plate body can be filtered to prevent the impurities in the water from affecting the pipeline. In addition, by loosening the screws on the sealing plate and pulling the sealing plate outward through the groove, the filter can be pulled out from the inside of the water tank, and then the filter can be disassembled and cleaned, which is convenient for the installation of the filter.
