Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

Example:

A sealing ring radial force testing platform as shown in FIGS. 1 to 2 includes a first testing platform 1 , a second testing platform 2 and a pressure testing structure 3 .

The first test stand 1 has a first semicircular work surface 11 and a first test surface 12, the second test stand 2 has a second semicircular work surface 21 and a second test surface 22, and the first test surface 12 has a first test surface 12.

The first semicircular working surface and the second semicircular working surface are covered by the sealing ring at the same time. Under the radial force of the sealing ring, the pressure sensor and the hard block are squeezed against each other, and the sealing ring acts on the hard The radial force on the block and the pressure sensor is uniform and stable, and the force measured by the pressure sensor is the radial force of the sealing ring. The tester: simple in structure, easy to operate, can quickly and accurately obtain the value of the radial force of the sealing ring , It plays an important role in stabilizing the sealing performance of the sealing ring, improving the service life of the sealing ring and improving production efficiency.

Preferably, the first groove 121 is set in the middle of the first test surface 12 , and the second groove 221 is set in the middle of the second test surface 22 . It can make the force on the pressure sensor more uniform and the measurement result more accurate.

The axis of symmetry of the hard block 31 and the pressure sensor 32 is on the same horizontal line. The mutual force between the hard block and the pressure sensor is made uniform, and the measurement result is more accurate.

Both the first semicircular working surface 11 and the second semicircular working surface 21 are provided with scale marks 4 . When testing the radial force of the sealing ring, it is more convenient to place the sealing ring at a position where it is easy for the pressure sensor to measure the accurate radial force.

There are multiple scale lines 4 , and the zero scale line among the scale lines 4 is on the same horizontal line as the axis of symmetry of the hard block 31 and the pressure sensor 32 . The scale lines above and below the zero scale line are marked with symmetrical values. When measuring the radial force of the seal ring, the upper edge and lower edge of the seal ring can have the same value on the scale line, so the measured radial force is accurate.

The lower end of the first semicircular working surface 11 and the lower end of the second semicircular working surface 21 form an outward extension. The extension facilitates the operator to measure the radial force of the seal ring.

When in use, the first test surface 12 and the second test surface 22 cooperate, and the first test platform 1 and the second test platform 2 just form a circle. At this time, the gap between the hard block 31 and the pressure sensor 32 is in a zero state . The sealing ring covers the first semicircular working surface 11 and the second semicircular working surface 21, and the upper and lower edges of the sealing ring correspond to the scale line 4 with the same value, because the inner diameter of the sealing ring is smaller than the first semicircular The diameter of the circle formed by the shaped working surface 11 and the second semicircular working surface 21, so, under the action of the interference, the sealing ring makes the first test bench 1 and the second test bench 2 squeeze each other, and then When the hard block 31 and the pressure sensor 32 are pressed against each other, the pressure measured by the pressure sensor 32 is the radial force of the sealing ring.
