Abstract
The utility model relates to a high/low-temperature compression resilience performance tester for a rubber composite sealing gasket. The high/low-temperature compression resilience performance tester comprises a sealing gasket press seat, a press head, a pressurization system, a pressure and displacement testing system and a high/low temperature circulation measuring and controlling system, wherein the sealing gasket press seat is internally provided with an annular space and a temperature sensor, and the annular space and the temperature sensor are sequentially and firmly connected with a water thermal-insulation column and a pressure sensor; the annular space of the temperature regulating press seat is connected with the high/low-temperature circulation measuring and controlling system; and the press head of the sealing gasket is sleeved with a movable temperature regulating ring, and another annular space is formed in the temperature regulating ring and connected with the high and low temperature circulation monitoring system. During testing, the sealing gasket is placed between the temperature regulating press seat and the temperature regulating ring, when a required temperature is reached, the press head is put down, and a load is applied to test the high/low-temperature compression resilience performance of the sealing gasket.
Description
Technical field
The utility model relates to a kind of rubber composite gland bush height temperature and pressure withdrawal elastic energy tester, is applicable to the compression recovery performance of testing rubber base composite sealing material, belongs to rubber-based sealing material properties test apparatus field.
Background technology
Rubber combined seal pad comprises the seal pad of being processed by rubber-filler, rubber-plastics, rubber-fibre reinforced composite; Have a wide range of applications in fields such as communications and transportation, oil gas conveying, hydraulic pressure transmission, mechanical drive; Especially internal combustion engine locomotive such as aviation, automobile is to the demands for higher performance of rubber composite gland bush; Except that requiring sealing gasket to have better tension compressive strength and the sealing property, also require sealing gasket to have preferably height temperature and pressure withdrawal elastic energy, and the compression recovery performance of encapsulant have material impact to the sealing property of sealing gasket; Especially the compression recovery performance in high and low temperature environment; Because the locomitivity of the macromolecular chain segment of rubber substrate is obviously different in high and low temperature environment, high temperature lower seal pad meeting deliquescing, the compressibility and the plastic yield that increase material; Can increase the fragility of material, the compressibility of reduction material at low temperatures again, thereby have influence on the compression recovery performance of material, and then have influence on the sealing property of sealing gasket oil gas.Therefore, except the compression recovery performance of testing rubber compound seal plate in normal temperature air, the height temperature and pressure of testing rubber compound seal plate withdrawal elastic energy is to understand the important means of sealing gasket in high and low temperature environment lower seal performance.
At present, the method for testing rubber composite gland bush compression recovery performance mainly contains GB GB/T12622-2008, and method therefor and equipment are the compression recovery performances of test sealing gasket under normal temperature condition, but can not test the compression recovery performance in the high and low temperature environment.But sealing gasket is in the temperature environment of high low temperature alternation often in actual the use; High and low temperature environment must influence the compression recovery performance of sealing gasket; Therefore, the normal temperature compressed rebound performance of only testing sealing gasket can not truly reflect the compression recovery performance in the sealing gasket high and low temperature environment.
Summary of the invention
The purpose of the utility model is to provide a kind of rubber composite gland bush height temperature and pressure withdrawal elastic energy tester; Can overcome the deficiency of existing equipment; Can test sealing gasket compression recovery performance at normal temperatures separately, again can the compression recovery performance of testing rubber composite gland bush under high and low temperature environment.
The purpose of the utility model realizes through following technical scheme: a kind of rubber composite gland bush height temperature and pressure withdrawal elastic energy tester is provided, comprises sealing gasket wedge, pressure head and compression system, pressure and displacement test system, high low temperature circulation TT&C system.An annular space and temperature sensor are arranged in the sealing gasket wedge, and be fastenedly connected in proper order with water thermal insulation post, pressure transducer; The annular space of temperature adjustment wedge is connected with high low temperature circulation TT&C system.The sealing gasket pressure head is with the temperature adjustment ring of an activity, and there is an annular space temperature adjustment ring inside, and is connected with high low temperature circulation TT&C system.During test, gasket seal is placed between temperature adjustment wedge and the temperature adjustment ring, when reaching temperature required, puts down pressure head, imposed load, can test sealing gasket height temperature and pressure withdrawal elastic energy.
The beneficial effect of the utility model is; The rubber combined seal pad height temperature and pressure withdrawal elastic energy tester that provides; Can test the compression recovery performance of sealing gasket under normal temperature environment separately; Again can the compression recovery performance of testing rubber composite gland bush under high and low temperature environment, make test result more can reflect the compression recovery performance of sealing gasket under true environment.
