[0048] Example 5: The physical property testing machine provided in the above embodiments is further optimized. Specifically, Figure 1 As shown, the top of the water tank 2 is provided with several reflux ports 202, and a water retaining bar 201 is fixedly installed on the outer peripheral side of the top of the water tank 2; a drain pipe is provided on the back of the water tank 2, and a control valve is provided on the drain pipe.

The touch screen 101 provides an intuitive and convenient human-computer interaction interface. The operator can set test parameters, start and stop the test, etc. through simple touch operations, which greatly reduces the complexity and difficulty of the operation and improves work efficiency. The alarm 102 can promptly issue an audible and visual alarm when abnormal conditions occur during the test process, such as excessive pressure, abnormal flow, low liquid level, etc., to remind the operator to take measures and avoid potential safety accidents and equipment damage.

[0050] Further, such as Figure 1 As shown, optical safety gratings 4 are installed on both sides of the front of the cabinet 1. The two optical safety gratings 4 are connected to the controller. The optical safety gratings 4 are used to detect whether there is any illegal entry into the cabinet 1 during the test process, so that an alarm is issued through the alarm 102 when a violation is detected. The installation of the optical safety gratings 4 provides a reliable guarantee for the safety of personnel during the test process. During the test process, since the equipment may be in operation and there are dangerous factors such as high-pressure liquid inside, the optical safety gratings 4 can monitor the area in front of the cabinet 1 in real time. Once someone is detected to enter illegally, the alarm 102 is immediately triggered by the controller to sound an alarm, reminding the operator to stop the dangerous behavior. This effectively avoids people entering the dangerous area due to misoperation or negligence, and reduces the probability of personal injury accidents.

After the water is added, tighten the cover. If the flow rate is tested, open the valve 603 and start the electric pesticide sprayer. The electric pesticide sprayer sprays liquid into the return pipe 6 through the spray rod, and the liquid passes through the flow meter 604 to detect the flow rate. If the pressure is tested, close the valve 603, and the electric pesticide sprayer sprays liquid into the return pipe 6 through the spray rod. The pressure is detected by the pressure gauge 602 during the spraying process.
