Embodiment 1
[0033] Example 1: Corrosion test of 45# steel sea mud coating under simulated natural conditions of ebb and flow.
[0034] Test sample: 45# steel;
[0035] Test medium: Shihai sea water, Shihai sea mud in Xiamen sea area;
[0036] Test conditions
[0037] a) Test temperature: 45°C;
[0038] b) Time interval between high tide and low tide: 6h;
[0039] c) Test medium replacement frequency: 7d;
[0040] d) Test time: 30 days;
[0041] Experimental procedure
[0042] a) close the seventh manual valve 20 and the eighth manual valve 21, and open the remaining manual valves;
[0043] b) Put real sea mud in the test chamber 1, and embed the test samples in parallel, and the test samples need to keep a certain distance;
[0044] c) fill up the real sea seawater in the circulating sedimentation tank 4 and the clean water tank 5;
[0045] d) Set parameters such as test temperature, time interval between rising and falling tides, and test liquid level;
[0046] e) Openin...
Embodiment 2
[0052] By the comparison of the above table, the test sample tested by this test device has a similar corrosion form with the test sample in the natural environment, and the difference in corrosion rate can reflect the influence of test parameters, and has a certain acceleration, which illustrates the present invention The test device is reliable in simulating the corrosion of natural sea mud environment and testing the corrosion resistance of metals, and provides a test platform for marine engineering material selection and evaluation. Embodiment 2: The overload protection test of the electric diaphragm pump.

[0065] Embodiment 3: Water replenishment operation test of the clean water tank.
[0066] Test sample: none
[0067] Test medium: ordinary tap water
[0068] Test conditions
[0069] a) Test temperature: room temperature;
[0070] b) Time interval between high tide and low tide: 2h;
[0071] Experimental procedure
[0072] a) close the seventh manual valve 20 and the eighth manual valve 21, and open the remaining manual valves;
[0073] b) Add half a box of ordinary tap water in the circulating sedimentation tank 4, and fill up the ordinary tap water in the clear water tank 5;
