Simulated marine corrosion test machine

Abstract

The invention relates to a metallic erosion experimental device, in particular to a marine erosion simulation tester for measuring erosion conditions of metals in the marine environment. The invention comprises an upper water storage tank, a lower water storage tank and a main water tank, wherein, a siphon tube is arranged between the main water tank and the lower water storage tank; one end of the siphon tube is positioned inside the main water tank and the other end of the siphon tube is inserted into the lower water storage tank; the upper water storage tank is communicated with the lower water storage tank through a water pipe capable of controlling the flow rate; a water inlet pipe capable of controlling the flow rate is arranged on the upper water storage tank and the other end of the water inlet pipe is inserted into the main water tank; an electrically controlled wave generating plate and a test strip holder are arranged inside the main water tank; a sea mud zone at the bottom is provided with a plurality of baffle plates; a liquid level controller is arranged on the upper water storage tank and connected with the water pipe through an electrical wire; a filter screen is arranged inside the lower water storage tank and water which is filtered by the filter screen passes through the water pipe and flows into the upper water storage tank; the wave generating plate is connected with a driving motor through a transmission tension rod; and the test strip holder can hang pieces respectively or hang pieces through electrical interlocking. The test result of the device is reliable and convenient for observation, and the simulation environment is various and true.

Description

technical field [0001] The invention relates to a metal corrosion experiment device, in particular to a simulated ocean corrosion test machine for measuring the corrosion of metal in the ocean environment. Background technique [0002] The ocean occupies more than 2 / 3 of the earth's surface and contains extremely rich mineral resources. With the rise of emerging marine industries such as maritime transportation, deep-sea mining, port terminals, oil and gas development, and marine biotechnology, human beings have gradually deepened the development and utilization of the ocean, and the scale of ocean development has also continued to expand. However, the marine environment is a highly corrosive disaster environment, and various materials are prone to corrosion, deterioration and damage in the marine environment. The loss caused by corrosion includes two categories: direct loss and indirect loss. It is a kind of damage that is quietly going on. The direct economic loss caused ...
