The environment tester is mainly composed of a host computer, a precipitation system, a spraying system, a condensation system, a corrosive gas input system, a temperature humidity regulator control system, a xenon lamp illumination system and a circulation drying system. The environment tester is mainly divided by a water sealing middle isolated layer into an upper chamber and a lower chamber and can carry out compound corrosion test and combined environment test.
Description
The present invention relates to a kind of artificial climate combined environment testing machine.
Aspect the general corrosion testing equipment of metal and protective layer thereof, current what generally adopt is salt-fog test, aspect the environmental test of equipment, material, employing be a series of single test.These single factor environmental tests have temperature, radiation (illumination), drench with rain, damp and hot, mould, salt fog, sand dust, vibration etc.The composite corrosion test equipment of researching to developing in ten or twenty year both at home and abroad closely, that has delivered has a following several types:
1. on the basis of salt-fog test, develop into the cyclic test of factors such as spraying, drying, humidity.This respect, the research institute of a few family of Japan and testing machine are made company and are developed with regard to beginning from early eighties, for example, all there are this type of product development in goods research institute, building research institute, and SUGA testing machine Co., Ltd. has produced CASSER-20L-CY type cycle spraying composite corrosion test machine on two mist tower CASS salt-fog test box foundations.There is a kind of Q-FOG CCT type cyclic corrosion testing machine that fan blower, air heater, steam generator and nozzle are positioned at the bottom that has in U.S. Q-PANEL company.The Heraeus company of Germany has a kind of nozzle to be located at HSNK type composite testing salt fog cabinet on the slide rail.The salt fog composite testing is desirable not enough to the improvement of simulation, and is difficult to solve the bad problem of major defect-reappearance that is present in salt-fog test equally.
2. on the cycle infiltration basis of (or claiming intermittently dipping), develop into the cyclic test of factors such as infiltration, drying, humidity.Cycle soak into the composite corrosion test machine have wheeled, the several types that flows out with solution of alternatively up and down.This respect also exists further simulation and the reproducible problem improved.
3. to feed one or more corrosive gass, control constant temperature and humidity or condensation perhaps then have the cyclic test of dry run.This type of test generally only is used to simulate industrial atmospheric.
4. the combined environment test of several environmental factor combinations.For example, has the combined environment test machine of temperature, humidity, vibration three factors, this testing machine, the existing product of development voluntarily of China's air line.
The purpose of this invention is to provide a kind of simulation, acceleration and reappearance and meet the requirements of compound (comprehensively) corrosion testing machine comprehensively atmospheric corrosion, for the corrosion of material and protective layer provides a kind of multi-functional, as can to adapt to multiple international standard and national standard corrosion test method and environmental test method testing machine that has with the field of wearing out, particularly provide a kind of while can corrode testing machine with aging compbined test and multifactor combined environment test.
Technical solution of the present invention is that testing machine mainly is made up of a main frame and quadruplet auxiliary equipment.Body has the levels double-chamber structure, and by rainfall system, spraying system, feeding corrosive gas system, temperature, wet regulator control system, the elevating mechanism and the rotating mechanism of xenon lamp lighting system and aeration drying system and cycle lifting and regularly continuous rotation are formed.The two chambers of levels adopt stainless steel to do interior exterior skin, and design two kinds of experimental enviroments respectively.Last chamber is illumination, hothouse; Following chamber is dampening chambers such as humidity, rainfall, spraying, condensation and feeding corrosive gas.
But the sample turntable mounting structure that testing machine adopts the cycle lifting and rotates continuously, sample is fixed on the anchor clamps of lifting frame inner plane rotating disk, and sample lifting frame loam cake is established the water seal cutter, establishes water sealed tank around the middle interlayer, makes the middle interlayer that forms a water seal up and down between the chamber.
The present invention combines in multiple single test on the machine, and the function that is formed by levels double-chamber structure and eight controllable environment factors makes this testing machine can carry out 18 kinds of act.std corrosion tests and environmental test.Eight controllable environment factors of the artificial climate combined environment testing machine of two groups of multiple-factor circulation comprehensives effect can be carried out compound corrosion-aging test and environmental test.
Fig. 1 is a synoptic diagram of the present invention.
This artificial climate combined environment testing machine is by main frame 1 and quadruplet auxiliary equipment: spraying plant 6, electric control cabinet 7, air-breather 8 and rainwater spray equipment 9 constitute.
