Problems solved by technology

[0002] There are two forms of sealing rings in practical applications: static sealing and dynamic sealing. The current dynamic test equipment for sealing rings usually has a fixed sealing chamber, and the test shaft rotates, and it is carried out in a dust-free environment. The country also has the relevant standards for the test of the lip seal ring of the rotating shaft, but for the seal ring installed in the cavity that needs to rotate and in the muddy water environment, it is difficult to test the muddy water sealing performance before installation Detection problems, such as the sealing ring on the wheel hub of the car, when driving in a muddy environment, the muddy water easily enters the inner side of the sealing ring and damages the sealing lip, causing the sealed liquid to leak, resulting in the failure of the sealing ring

Embodiment 1

[0021] Such as figure 1 with figure 2 As shown, the sealing ring anti-mudwater performance shell rotation test machine includes a bench 1, a pulley 4, an eccentric test shaft 8, muddy water mixing and spraying equipment 9 and an oil injection pipe 13, and a motor 2 is arranged in the bench 1 and on the table. , fixed main shaft 3, rotating chamber 5 and muddy water shield 11, described rotating chamber 5 is provided with heating pipe 12, described rotating chamber 5 is connected and fixed with belt pulley 4 by screw, described in rotating chamber 5 The cavity eccentric disk 6 is arranged on the upper part, the eccentric test shaft 8 is arranged on the fixed main shaft 3, the protective cover door 14 is arranged on the muddy water protective cover 11, and the muddy water injection pipe is arranged on the muddy water mixing and spraying equipment 9 10. The muddy water injection pipe 10 is inserted into the hole provided on the muddy water protective cover 11, and a muddy water...

Embodiment 2

[0029] With embodiment 1, the difference is that its test method of the anti-mud water performance shell test machine of the sealing ring also includes the following steps:

[0030] The sixth step, repeat the test: use two sealing rings of the same model specification to repeat the above steps for the test.

Embodiment 3

[0032] With embodiment 1, the difference is that its test method of the anti-mud water performance shell test machine of the sealing ring also includes the following steps:

[0033] The sixth step, repeat the test: use six sealing rings of the same model specification to repeat the above steps for the test.

[0034] Like this when in use, sealing ring anti-mud water performance shell of the present invention rotates testing machine and test method thereof, and rotating cavity 5 is used for containing test liquid and installing sealing ring 7, and sealing ring 7 is installed on the testing machine, in certain test Under the condition of operation, spray muddy water to the outer end of the sealing ring 7 regularly, so as to test the muddy water-proof sealing performance of the sealing ring 7.

Abstract

The invention belongs to a sealing element performance detecting device and a testing method thereof, namely a shell-rotation tester for muddy water resistance of a sealing ring and a testing method thereof. The tester comprises a rack, a belt wheel, an eccentric test shaft, a muddy water stirring and jetting device and an oil filler pipe. A motor, a fixed main shaft, a rotating chamber and a muddy water shield are arranged in the tack and on a table top. A heating pipe is arranged in the rotating chamber. The rotating chamber is connected and fixed to the belt wheel. An eccentric chamber disc is arranged on the rotating chamber. The eccentric test shaft is arranged on the fixed main shaft. A shield door is arranged on the muddy water shield. A muddy water jetting pipe is arranged on the muddy water stirring and jetting device, and is inserted in a hole formed on the muddy water shield. Besides, a muddy water collecting tank is arranged below the muddy water jetting pipe. The tester can be used for realizing performance assessment on the sealing ring product in the presence of muddy water during shell rotation, thereby guaranteeing the quality of the product and improving the reliability of the sealing ring product as well as prolonging the service life of the sealing ring product.
