DETAILED DESCRIPTION
[0029] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings.
[0030] In the description of this specification, the description with reference to the terms "certain embodiments", "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiments or examples are included in at least one embodiment or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.
[0031] The present application embodiment discloses a peristaltic pump performance testing system, referring to Figure 1 and Figure 2 , including a container rack 1, on which a liquid container 1 2 and a liquid container 2 3 are placed, the liquid container 2 3 is arranged above the liquid container 1 2, and a drain pipe 31 is passed through the bottom of the liquid container 2 3, and one end of the drain pipe 31 away from the liquid container 2 3 is connected to the liquid container 1 2, and an electromagnetic valve 5 is connected to the drain pipe 31, and the electromagnetic valve 5 is used to control the opening and closing of the drain pipe 31; a weighing module 6 fixed to the container rack 1 is arranged at the bottom of the liquid container 2 3, and the weighing module 6 is electrically connected to the external operating system; a peristaltic pump 4 is fixed to one side of the container rack 1, and the peristaltic pump 4 includes a driver 41, a pump head 42 and a hose 43, the output end of the driver 41 is connected to the pump head 42, the hose 43 is passed through the pump head 42, one end of the hose 43 is connected to the liquid container 2 and extends to the bottom of the liquid container 2, and the other end is connected to the liquid container 2 3.
[0032] The liquid in the liquid container 1 2 is transported to the liquid container 2 3 by the peristaltic pump 4. A weighing module 6 is set at the bottom of the liquid container 2 3 to collect the data of the weight change of the liquid container 2 3 in real time. The operating system analyzes and processes the collected data. The test system eliminates the manual weighing operation, reduces the measurement error, and improves the measurement accuracy, so that the flow performance of the peristaltic pump 4 can be accurately obtained. The liquid in the liquid container 2 3 flows into the liquid container 1 2 through the drain pipe 31, realizing the process of liquid recycling. The opening and closing of the drain pipe 31 is automatically controlled by the solenoid valve 5 to avoid human interference affecting the accuracy of weighing.
[0033] Reference Figure 3 and Figure 4The weighing module 6 includes a weighing sensor 61 fixed on the container rack 1. The detection end 611 of the weighing sensor 61 is fixedly connected to a tray 62. The tray 62 is a circular plate-shaped structure. A gap is provided between the bottom of the tray 62 and the container rack 1 to ensure the displacement space of the tray 62 under the action of gravity. A placement groove 621 is provided on the top of the tray 62. The liquid container 23 is placed in the placement groove 621 to ensure the stability of the liquid container 23. When in use, the weight change data of the liquid container 23 is collected in real time through the weighing sensor 61, which saves the operation of manual weighing and improves the weighing accuracy.
[0034] The tray 62 is provided with a through hole 622 through which the drain pipe 31 can pass.
[0035] There is a gap between one end of the hose 43 close to the liquid container 2 3 and the liquid level 7 in the liquid container 2 3. When the peristaltic pump 4 transports liquid in the liquid container 2 3, there is a gap between the end of the hose 43 and the liquid level 7 in the liquid container 2 3, thereby avoiding the influence of the hose 43 on weighing and improving the weighing accuracy.
[0036] Reference Figure 3 and Figure 5 A support plate 11 is fixedly connected to the container rack 1, and a mounting groove 111 for placing the weighing sensor 61 is opened in the middle of the support plate 11. The mounting groove 111 runs through the support plate 11, and a supporting plate 12 is fixedly connected to the bottom of the support plate 11 at the position of the mounting groove 111. One end of the weighing sensor 61 is fixedly connected to the supporting plate 12.
[0037] During installation, the weighing sensor 61 is placed in the installation groove 111 to reduce the contact area between the weighing sensor 61 and the outside, thereby reducing the influence of dust on the sensitivity of the weighing sensor 61 .
[0038] A pad 63 is connected between the supporting plate 12 and the weighing sensor 61 . The pad 63 is arranged at one end of the weighing sensor 61 with a wire 612 , so that the detection end 611 of the weighing sensor 61 is suspended, thereby ensuring the displacement space of the detection end 611 of the weighing sensor 61 .
[0039] Reference Figure 6 A clearance space 14 is reserved between the supporting plate 12 and the mounting groove 111 for the wire 612 on the weighing sensor 61 to pass through. It is convenient for the wire 612 on the weighing sensor 61 to pass through the clearance space 14.
[0040] A circular clearance channel 112 is provided on the support plate 11 for the drain pipe 31 to pass through. The clearance channel 112 corresponds to the through hole 622 on the tray 62. The diameter of the clearance channel 112 is larger than the diameter of the drain pipe 31, so that a gap is left between the drain pipe 31 and the inner wall of the clearance channel 112 to avoid interference between the drain pipe 31 and the support plate 11 that affects the weighing accuracy.
[0041] Reference Figure 6 and Figure 7 A fixing rod 13 for fixing the hose 43 is fixedly connected above the liquid container 1 2 and the liquid container 2 3 on the container rack 1. A card slot 131 is provided on one side of the end of the fixing rod 13. The hose 43 is card-connected in the card slot 131 to facilitate the disassembly and assembly of the hose 43. The fixing rod 13 ensures the stability of the hose 43 and reduces the influence on the weighing.
[0042] The implementation principle of a peristaltic pump performance test system in an embodiment of the present application is: before the peristaltic pump 4 is tested, the liquid container 2 is initially filled with a sufficient amount of liquid, the liquid container 2 is initially empty, and the weighing module 6 is reset to zero. When the peristaltic pump 4 starts to run, the solenoid valve 5 is closed, and the liquid in the liquid container 2 is drained into the liquid container 2 3 through the peristaltic pump 4. The weighing sensor 61 measures the weight of the liquid container 2 3 in real time and records it through an external operating system, and the data collected by the weighing module 6 gradually increases; the solenoid valve 5 is opened, and the liquid in the liquid container 2 3 flows back to the liquid container 2 through the drain pipe 31, and the data collected by the weighing module 6 gradually decreases to 0 or a very small weighing value; the opening and closing of the solenoid valve 5 is controlled at a fixed time, and the data of the change in the weight of the liquid in the liquid container 2 3 is collected, and then the data is analyzed and processed; the present application eliminates the operation of manual weighing, reduces measurement errors, and improves measurement accuracy, so that the flow performance of the peristaltic pump 4 can be accurately obtained.
[0043] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present application.
