Description
Technical field
The present invention relates to a kind of band temperature control, pressure fluid round-robin seal reliability test.
Background technology
Rubber has excellent high resiliency, is widely used as encapsulant.Rubber seal plays an important role in leading-edge fields such as military project, Aero-Space, nuclear industry, and the ageing failure of seal tends to cause heavy economic losses and serious accident.According to investigations, the U.S. " challenger " in 1986 number space shuttle lift-off blast is due to rubber seal lost efficacy.Therefore how to pass through the reliability of test assessment seal, predict that promptly just seem particularly important the serviceable life of seal.The fail-safe analysis of macromolecular material seal in the past (life appraisal) does not have special test unit, can only carry out entry evaluation with reference to some test method, as adopting permanent compression test method (GB/T7759-1996, ASTM D 395-2003), these test methods have only considered that material is the condition of normal pressure at air, environmental pressure.
Summary of the invention
The purpose of this invention is to provide a kind of band temperature control, pressure fluid round-robin seal reliability test.
The technical solution used in the present invention is:
A kind of band temperature control, pressure fluid round-robin seal reliability test, it comprises constant temperature water tank, constant temperature water tank is connected to out water regulating valve by pipeline, go out water regulating valve and be connected to water pump by pipeline, water pump is connected to another by pipeline and goes out water regulating valve, goes out water regulating valve and is connected to aciculiform adjustment valve by pipeline, and aciculiform is adjusted valve and is connected to tensimeter by pipeline, tensimeter is connected to the seal jig by pipeline, and the seal jig connects back constant temperature water tank by pipeline.
The seal jig comprises jig, following jig, the middle part of the middle part of last jig and following jig is provided with dismountable fastening screw, the sidepiece of last jig is provided with water inlet, the sidepiece of following jig is provided with water delivering orifice, last jig bottom is provided with the through hole that becomes equilateral triangle to distribute around the center, and following jig top is provided with the through hole that becomes equilateral triangle to distribute around the center.
The invention has the beneficial effects as follows: 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.Can be applicable to important hydraulic seal fail-safe analysis technical field: as the sealing reliability analysis of the fluid circulation system of nuclear industry system, the fail-safe analysis of airspace engine propellant, missile propellant seal etc.

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.
