Abstract

The invention discloses a device and method for verifying oil resistance of a rubber seal ring. The device comprises a base, a supporting rod, a detection clamping plate, clamping plates, the to-be-tested rubber ring, a spiral pipe and an oil tank. The supporting rod penetrates through the oil tank, the spiral pipe heats liquid in the oil tank, and the to-be-tested rubber ring is connected with the perforated end of the oil tank and is adjusted through a screw rod and a nut. The device has the advantages that the structure is simple, the number of connecting parts is small, and the device canbe operated and used in a standard laboratory or a production site; the number of rubber seal ring performance evaluation and verification parameters is large, and by adjusting the nut, the spiral pipe and a booster pump and injecting different kinds of oil liquid, the compression amount, temperature and pressure of the rubber seal ring and the influence of the sealing oil liquid on the sealing performance of the rubber ring are evaluated and verified; the sealing performance of the rubber ring in the actual use process is objectively represented, so that a quantifiable sealing property representation device is provided for batch quality assessment of the rubber ring and analysis of the oil leakage amount of failure parts.

Description

technical field [0001] The invention relates to the field of a rubber ring sealing performance characterization test device, in particular to a rubber sealing ring oil resistance verification device and method. Background technique [0002] The sealing ring is one of the most commonly used parts in the industrial field. The sealing ring is used to be installed on various mechanical equipment, and it can be sealed under the specified temperature, pressure, compression rate and different gas and liquid environments. Functional parts. The main factor affecting the sealing ability of the sealing ring is the sealing ring material. Therefore, GB / T1690-2010 "Test Method for Vulcanized Rubber or Thermoplastic Rubber Heat-Resistant Body" stipulates the method of evaluating the effect of liquid on rubber by testing the performance change of rubber before and after soaking in the test liquid, and then characterizing the sealing performance of rubber. Authorized notification number CN...
