Embodiment
Be described further below in conjunction with accompanying drawing.
As Fig. 1, a kind of band temperature control, pressure fluid round-robin seal reliability test, it is characterized in that: it comprises constant temperature water tank 1, constant temperature water tank 1 is connected to out water regulating valve 2 by pipeline, go out water regulating valve 2 and be connected to water pump 3 by pipeline, water pump 3 is connected to another by pipeline and goes out water regulating valve 4, go out water regulating valve 4 and be connected to aciculiform adjustment valve 5 by pipeline, aciculiform is adjusted valve 5 and is connected to tensimeter 6 by pipeline, tensimeter 6 is connected to seal jig 7 by pipeline, and seal jig 7 connects back constant temperature water tank 1 by pipeline.
As Fig. 2 and Fig. 3, the seal jig comprises jig 71, following jig 72, the middle part of the middle part of last jig 71 and following jig 72 is provided with dismountable fastening screw 73, fastening screw 73 tops are provided with clamp nut 731, the sidepiece of last jig 71 is provided with water inlet 711, the sidepiece of following jig 72 is provided with water delivering orifice 721, last jig 71 bottoms are provided with the last through hole 712 that becomes equilateral triangle to distribute around the center, and following jig 72 tops are provided with the lower through-hole 722 that becomes equilateral triangle to distribute around the center.
Preferably, the aperture of the aperture of last through hole 712 and lower through-hole 722 equates.
As Fig. 2 and Fig. 4, at seal 9 middle parts passage 91 is set, the aperture of passage 91 is last through hole 712 or lower through-hole 722 apertures 1.1-1.2 a times, when testing, make the last through hole 712 of jig 7, lower through-hole 722 over against, seal 9 places through hole 712, between the lower through-hole 722, the passage 91 that makes seal 9 is over against last through hole 712 and lower through-hole 722, regulating upward by fastening screw 73, jig 71 arrives certain distance with following jig 72, a definite compression set amount just takes place in seal 9, therefore, it can simulate the stress that obtains true environment for use, simultaneously, because constant temperature water tank 1 and water pump 3 provide the liquid medium of steady temperature pressure, liquid medium is transported to the water inlet 711 of jig 71 by pipeline, further, the flow through passage 91 of seal 9 of the liquid medium of steady temperature pressure, enter pipeline from water delivering orifice 721 again, flow back to constant temperature water tank 1, when the liquid medium of steady temperature pressure is flowed through the passage 91 of seal 9, seal 9 can be simulated the fluid temperature pressure that obtains under the true environment, when environment for use is mordant liquid, liquid in the pipeline can be changed into corresponding corrosive liquid, therefore, seal 9 can be simulated the erosion that obtains the liquid medium under the true environment, simultaneously, because seal jig 7 places baking oven 8, therefore, seal 9 can obtain the temperature effect under the environment for use.
To sum up, the integrated survey of this device the influences of temperature, stress and medium pressure liquid and these factors of corrosivity to the sealing property of seal, can obtain the test figure that is consistent with actual operating position more realistically, according to test figure, the assessment that can make realistic operating position to the useful life longevity and the reliability of macromolecular material seal.
