Technical field
The utility model relates to a kind of ageing test apparatus of simulating real extra large environment and soaking; include a constant temperature water tank; for Control experiment process ocean temperature; heat exchanger is furnished with in constant temperature water tank; heating and cooling adjustment is carried out to ocean temperature; the infusion chamber of different size, for simulating variable concentrations sea water immersion environment, is all furnished with the orifice plate placing test specimen, can places the test specimen of multiple different size to make full use of space in infusion chamber.
Background technology
Ocean is not only and is had the treasure-house of affluent resources, or human survival and development indispensable space environment.Since 21 century, each state all pay much attention to marine resources development utilize, China be one populous, the country that resource is relatively in short supply, especially average resource per capita is significantly less than world average level especially.But China has the seas under its jurisdiction of nearly 3,000,000 square kilometres, mainland coastline reaches 1.8 ten thousand kilometers, long 140,000 kilometers of the water front on more than 6500 island.Exploitation ocean resources, develop economy in coastal regions, have great strategic significance to China's economic construction and social development.
The development and utilization of ocean resources be unable to do without the construction of offshore based installations, and the offshore engineering structures such as boats and ships, port installations and bridge spanning the sea use a large amount of material installations, and input amount is increasing year by year.Due to the physical environment of ocean harshness, the burn into of material structure dissolves, unavoidably swelling.Once there is the outward appearance that marine corrosion not only affects material in metal material, its mechanical property will change, and lose due intensity, hardness and toughness, until material complete failure structure is destroyed.After non-metal material surface contacts with Seawater, sea water solution can be diffused into material internal gradually, material surface and inside all may produce a series of change, if rubber and plastics are by possibility all or part of dissolving or swelling after solvent action, solution can cause swelling or weightening finish after immersing material internal, can bubble in surface, roughening, variable color, and inner generating function weakens or loses; Macromolecule organic may decompose by Seawater effect.According to statistics, the destruction of hull about 90% is lost owing to material function, and the soak test research of material in marine environment is subject to the attention of various countries always.Therefore, the real sea for material is soaked and material function failure Mechanism carries out some work of benefiting our pursuits, and for the design of oceanographic engineering, selection, protection and new material exploitation provide foundation, is of great practical significance.
It is more objective to study different materials immersion under real extra large environment and explore material ageing failure mechanism under marine environment, truly, but because real extra large environmental impact factor is complicated and changeable, carry out correlation test research in the case to be often difficult to continue for a long time to carry out, simultaneously due to real extra large bad environments, be unfavorable for that related scientific research activity is carried out in a deep going way, and develop the ageing test apparatus of the real extra large environment immersion of a set of simulation, contribute to long-time, continue, depth carries out the research work of immersion aging test, production equipment design for using in real extra large environment and maintenance are provided objective data by this, for immersion ageing process and the material function failure mechanism of research material, improve material property further, improve quality of materials and scientific basis is provided.
Summary of the invention
The purpose of this utility model is: for simulation material and component are immersed in the performance under different seawater salinity, intends the pilot system that the real extra large environment of a set of simulation of exploitation soaks, and this system can be carried out long-time constant temperature to test specimen independently and be soaked environmental test.
To achieve these goals; the present utility model adopts following technology to be achieved: a kind of ageing test apparatus of simulating real extra large environment immersion comprises constant temperature water tank, infusion chamber, suction pump, drinking-water pipe, oxygen increasing pump, drainpipe, draining valve, lid; it is characterized in that; infusion chamber is placed in inside constant temperature water tank; different size infusion chamber can be placed in described constant temperature water tank inside, can simulate different concentrations sea water environment simultaneously.Described each infusion chamber inwall has two-layer baffle plate, and orifice plate is placed on baffle plate, can place the test specimen of multiple different size simultaneously, make full use of space in such infusion chamber; Constant temperature water tank lower inside has heat exchange pipeline, and constant temperature water tank side connects compressor train, and place lid above constant temperature water tank, outside surface has heat-insulation layer, makes the inside water temperature keep constant; Described oxygen increasing pump water pipe is connected with infusion chamber seawater, makes the inside even water temperature; Described electrical control cabinet is made up of pilot lamp, touch-screen, scram button, voltage table, reometer and PLC; Described PLC is electrically connected with temperature sensor, compressor train.
Infusion chamber of the present utility model and constant temperature water tank material are the stainless steel of 316L, and accessory selects the stainless steel of the 316L of seawater corrosion resistance; Lower water temperature system heat exchanger tube adopts the 316L stainless-steel tube of high pressure resistant seawater corrosion resistance; Two-phase stainless steel seawater water pump selected by suction pump, and the pipeline of pumping conduit and drainage pipeline selects 316L stainless steel to make.
The utility model structure is simple, easy to operate, automaticity is higher, without the need on duty for a long time, can simulate real sea and soak environment, realize the assay to material corrosion and inefficacy ageing properties in laboratory; By the setting of test parameters and process of the test, in laboratory, carry out material soak aging test, obtain great number tested data in the short period of time, for research material immersion corrosion aging rule and exploitation new material provide the test figure of science.
