In actual use, the second pressing assembly 20 is provided with a probe hole 25 to facilitate the installation of the temperature probe. Wherein, the quantity of probe hole 25 is two, and two probe holes 25 correspond a heating hole 24 setting respectively, promptly: one of the probe holes 25 is provided in the gland 23 and the other probe hole 25 is provided in the base 22. Such an arrangement further facilitates detection of the amount of heat dissipated by each heating element by the temperature probe. The repairing device further comprises a controller, the temperature probe and the heating element are electrically connected with the controller respectively, the temperature probe can convert detected temperature signals into electric signals to be transmitted to the controller, the controller receives the temperature signals, processes and analyzes the temperature signals, and then sends instruction signals to the heating element to control the heating temperature of the heating element.

It should be noted that how the heating element is heated, how the temperature probe detects the temperature, and how the controller controls the heating element and the temperature probe belong to the existing mature technology, and do not belong to the improvement point of the present application, and therefore, the details are not described again.

As can be seen from the above, the repairing device of the present application is actually used as follows:

before the sealing ring is bonded, the repairing device is disassembled, and the matching surfaces of the repairing device are cleaned by using Weidil detergent (or ethanol), so that each matching surface is clean and free of impurities. And cleaning two sections at the fracture of the sealing ring by using a cleaning agent, coating a vulcanizing agent after cleaning, and standing for a period of time.

After the preparation work is completed, the lower press plate 102 is fixed relative to the base 22, so that the axis of the second groove on the lower press plate 102 coincides with the axis of the fourth groove 212 on the base 22, and a certain gap is provided between the lower press plate 102 and the base 22, so as to facilitate the distance adjustment through the adjusting member. The left fracture side of the sealing ring is embedded into the second groove and the fourth groove 212, and then the upper pressure plate 101 is pressed against the lower pressure plate 102, so that the first groove 111 is opposite to the second groove, and the left fracture side of the sealing ring is pressed by the groove wall of the first groove 111 and the groove wall of the second groove. Next, the right fracture side of the seal ring is inserted into the other side of the fourth groove 212, and then the second side press seat 13 is pressed against the base 22, so that the first groove 111 on the second side press seat 13 is opposite to the fourth groove 212 on the base 22, so as to clamp the right fracture side of the seal ring through the second side press seat 13 and the base 22. Then, the gland 23 is buckled on the base 22, so that the third groove 211 on the gland 23 and the fourth groove 212 on the base 22 form a pressing channel, so as to press the left side and the right side of the fracture of the sealing ring in the pressing channel through the gland 23 and the base 22. Finally, the adjusting member is adjusted to cause the lower press plate 102 to move towards the base 22, and the upper press plate 101 moves synchronously with the lower press plate 102, so that the lower press plate 102 and the upper press plate 101 can be pressed against the base 22 and the gland 23, respectively. At this time, both fracture ends of the seal ring located in the pressing passage can be sufficiently contacted with the adhesive. After the above-described structural assembly is completed, the heating element is inserted into the heating hole 24, and the temperature probe is inserted into the probe hole 25, so that the heating element is electrically energized to heat the adhesive for curing. After the heating is finished, all parts of the repairing device are disassembled, the bonding position of the sealing ring is checked, and the repairing operation of the sealing ring is realized.

In the whole repairing process, the repairing device is only assembled and disassembled to repair the fracture of the sealing ring, the sealing ring is not required to be disassembled relative to equipment, so that the labor and time cost are effectively saved, and the safety risk is reduced. Particularly in emergency, and when no new sealing ring replacement part exists, the repairing device can repair the broken part of the sealing ring, and the purchasing time and purchasing period are obviously reduced.
