Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model be utilize that dripping type transfusion device principle development and Design forms for realizing the corrosion environment analogue means of corrosion fatigue test.Needs according to test to corrosion environment, can realize the simulation of instillation fog environment and two kinds of corrosion environments of corrosive liquid immersion type and control.This dripping type corrosion environment device is applicable to tired crooked style, and specimen shape is the sample that notched specimen, taper or hourglass shape etc. can be prejudged out fatigue break position.Concrete technical scheme is as follows: as shown in Figure 1, dripping type corrosion fatigue environment control unit mainly consists of instillation unit and liquid collecting unit two parts;
Instillation unit: (1) mainly realizes corrosive liquid storage and corrosion environment is controlled, specifically by support 1 upper end, hang with reservoir 2, reservoir 2 is provided with reservoir inlet and reservoir liquid outlet, the reservoir liquid outlet of reservoir 2 connects the inlet of catheter 3, and the liquid outlet of catheter 3 is adjusted knob 4 connection instillation by instillation and chewed 5; (2) assembly material of this unit is according to corrosive liquid characteristic, and 5 materials are chewed in reservoir 2, catheter 3 and instillation can adopt glass or plastics, or other resistant material, and adjustment knob 4 materials that instil can adopt plastics or rubber, or other resistant material; (3) in use, instillation is chewed to 5 and be fixed on the position that fatigue break will occur sample 9; (4) aerosol environmental simulation method is realized in instillation unit: on the one hand, adjust knob 4 make corrosive liquid drip several constantly dripping to fatigue testing specimen 9 with the unit interval of regulation by instillation; On the other hand, the corrosion drop on sample 9 will evaporation in tens of seconds.Like this, by controlling the speed of drop and the balanced degree of an evaporation speed of corrosive liquid, can realize the corrosion environment of aerosol or nearly aerosol.Although corrosion drop is not formed aerosol environment by flash evapn after fatigue testing specimen 9, this corrosive liquid evaporates the impact that the required several seconds in fact can't be on the fatigue lifetime of sample 9.This is to a few hours, to grow to tens of hours because Fatigue Test Time is few often, and the short impact of tens of seconds can be ignored completely; Meanwhile, the true corrosion environment of actual parts also often cannot quantize, but judgement obtains according to the observation, so the quantification of corrosion environment is accurately controlled at and in torture test, does not have practical significance.And the determination methods of the utility model device is just consistent with the determination methods of actual parts corrosion environment, practical application also shows that it has more practicality.(5) analogy method of immersion type corrosion environment: when controlling the larger formation of corrosive liquid flow to the continuous fluid injection of sample, can realize immersion type corrosion environment.Now, the flow control of corrosive liquid realizes the ebullator 8 of using the corrosion-resistant fractional motor of controllable flow rate instead.
Liquid collecting unit: (1) mainly collects the corrosive liquid from fatigue testing specimen 9 flies, according to fog corrosion environment and immersion type corrosion environment, the shape of liquid collecting unit is divided into and absorbs two kinds of evaporation mask 6 and slot type return tanks; (2) absorb evaporation mask 6 materials and adopt the good corrugated paper of hydroscopicity, according to the shape of fatigue tester, can be made into easily various simple shapes, be fixed on fatigue tester, and fatigue testing specimen 9 is covered in wherein.Be illustrated in figure 2 the absorption evaporation mask 6 for rotating bending test machine.Due to the corrosive liquid consumption of aerosol corrosion environment seldom, so the large portion of corrosive liquid being instilled on sample 9 is evaporated, is not evaporated on a small quantity and falls or the corrosive liquid that splashes will be housed in sample 9 corrugated paper liquid-collecting cover around and absorb and evaporation in time; (3) as shown in Figure 3, slot type return tank is made by organic glass or quartz glass, and the liquid of flowing through after sample 9 will be refluxed groove and collect and be stored in corrosive liquid collection box 7, then by ebullator 8 pumps to other end outlet, is flowed out, and realizes the circulation of corrosive liquid.
Existing corrosion fatigue environmental cabinet is all hermetic type, and cost is higher than the decades of times of this device, and complicated operation corrosion environment is invisible.Compare with corrosion environment analogue means in the past, the utility model has the advantages that and greatly widened corrosion environment scope, can provide on a large scale from humidity to the etching condition scope of soaking; The control of corrosion environment is significantly simplified, is easily gone; The scope of application is wider, has both been applicable to rotary bending fatigue test, is also applicable to three, four-point bending torture test; Cost is extremely cheap, is even close to zero.
