Technical Field
[0001] This application belongs to the field of salt spray environment test chamber manufacturing technology, and particularly relates to a device for simulating seawater splash erosion environment. Background Technology
[0002] Currently, there are no experimental devices for testing the effects of sea waves on corrosion, such as seawater splash, spray, and droplet erosion. There is a need to develop a device that simulates the seawater splash erosion environment to mimic the erosion environment of waves and droplets in the marine environment and meet the testing requirements for sea wave erosion environment. Utility Model Content
[0003] Purpose of the utility model: To provide a device for simulating the erosion environment of seawater splash, used to simulate the generation of ocean waves and spray, and to verify the adaptability of the device in the marine environment.
[0004] Technical solution:
[0005] An apparatus for simulating the erosion environment of seawater splash includes: a seawater tank, a splash system, and an electrical control system. The seawater tank is a solution tank containing a test base for placing the product to be tested. The splash system includes: a circulating pump, an ejector, and a baffle. The inlet of the circulating pump is connected to the seawater tank via a first pipe; the outlet of the circulating pump is connected to the ejector via a second pipe. The baffle is tilted above the test base, and the outlet of the ejector is aligned with the baffle. The sprayed water flow is blocked by the baffle and splashes onto the product to be tested. The electrical control system includes a frequency converter and a touchscreen recorder for data acquisition and recording. The output of the frequency converter is connected to the power input of the circulating pump; the touchscreen recorder is connected to the frequency converter.
[0006] Furthermore, a ball valve and a filter are installed on the first pipeline.
[0007] Furthermore, a check valve, a flow meter, and a pressure regulating valve are installed on the second pipeline.
[0008] Furthermore, the electrical control system also includes a pressure controller, the input of which is connected to the output of the flow meter.
[0009] Furthermore, the first and second pipelines are made of PP pipes.
[0010] Furthermore, the baffle is fixed above the test base by an adjustable bracket, and the baffle angle is adjustable.
[0011] Beneficial technical effects:
[0012] Ships, aircraft, and other equipment operating at sea are frequently subjected to a range of external factors, including alternating wet and dry conditions, seawater spray, sunlight, corrosive components in the atmosphere, and oxygen. This harsh corrosive environment can easily lead to equipment failure. Laboratory tests typically employ neutral salt spray testing with a specific concentration of NaCl solution. This method relies on highly corrosive salt spray for corrosion testing, but the lack of impact force on the sample results in a slow corrosion rate. The seawater splash test device can simulate the impact of ocean waves, the corrosion from highly corrosive spray, and various other marine environmental factors such as seawater immersion, accelerating corrosion testing time and better reflecting actual marine conditions. The introduction of this new device will shorten corrosion testing time, improve the stability of corrosion tests, and provide reliable evidence for corrosion life. Attached Figure Description
[0013] Figure 1 This is a schematic diagram of the device for simulating the erosion environment of seawater splashing according to this utility model. Detailed Implementation
[0014] The present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0015] Equipment often encounters the effects of wave splash and seawater droplets during use at sea, which can lead to corrosion damage. The purpose of this invention is to provide a new type of test device that simulates the corrosive environment of waves and droplets in the marine environment, so as to solve the need for testing equipment against corrosion caused by waves and other factors.
[0016] Waves are primarily generated by seawater impacting obstacles. Based on this characteristic, the FJT-QA01F seawater splash simulation test device was developed. This specialized test equipment is designed and manufactured specifically for sea conditions, mainly used for environmental adaptability studies to resist seawater splash erosion. It is particularly suitable for accelerating the simulation of specific laboratory seawater splash environmental stress conditions to complete functional and performance testing and verification of certain equipment. This device sprays seawater solution onto a baffle (wave generator) via a jet. The high-speed flowing seawater breaks up upon encountering the obstruction, generating simulated waves. The flow rate of the seawater is infinitely adjustable through frequency converter control of the anti-corrosion solution pump and pressure regulating valve, thereby changing the magnitude and intensity of the impact force of the seawater on the baffle (wave generator). Changing the angle of the baffle (wave generator) alters the size and coverage of the splash. Controlling the seawater temperature simulates the ambient temperature, ensuring the temperature of the test sample matches the actual operating temperature. A touchscreen data logger effectively records and stores test data such as temperature, pressure, and flow rate, facilitating subsequent data analysis and management, thus improving the stability and reliability of the test.
[0017] The overall structure of the seawater splash simulation test device is as follows: Figure 1 As shown, the overall dimensions are 3100mm (length) × 1000mm (width) × 1900mm (height). A device simulating a seawater splash erosion environment includes: a seawater tank, a splash system, and an electrical control system. The seawater tank is a solution tank containing a test base for placing the product to be tested. The splash system includes: a circulating pump, an ejector, and a baffle. The inlet of the circulating pump is connected to the seawater tank via a first pipe; the outlet of the circulating pump is connected to the ejector via a second pipe. The baffle is tilted above the test base, and the outlet of the ejector is aligned with the baffle. The sprayed water flow is blocked by the baffle and splashes onto the product to be tested. The electrical control system includes a frequency converter and a touchscreen recorder for data acquisition and recording. The output of the frequency converter is connected to the power input of the circulating pump; the touchscreen recorder is connected to the frequency converter.
