Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically to a ceramic sealing ring strength testing device. Background Technology

[0002] Ceramic seals are industrial sealing components made of ceramic materials such as alumina and silicon carbide combined with special rubber. They have excellent high-temperature resistance, wear resistance, and corrosion resistance, and are widely used in new energy, chemical, and machinery fields. Strength testing of ceramic seals is a key step in ensuring their mechanical properties and reliability, typically encompassing multiple tests such as bending resistance, compressive strength, and tensile strength. During compressive strength testing, if the ceramic seal breaks, it can make cleaning the testing device difficult, affecting subsequent tests. Therefore, it is necessary to design a ceramic seal strength testing device that facilitates cleaning of debris and maintains the cleanliness of the strength testing apparatus. Summary of the Invention

[0003] The purpose of this invention is to provide a ceramic sealing ring strength testing device, which has the advantages of easy cleaning of debris and keeping the strength testing device clean.

[0004] The technical solution adopted is as follows:

[0005] A ceramic sealing ring strength testing device includes a support box with a circular hole at the top. A limit tube is installed inside the circular hole, and the upper end of the limit tube is connected to the upper end of the support box. A circular plate is vertically slidably installed inside the limit tube. A first telescopic mechanism is vertically installed inside the support box and connected to the circular plate. Multiple through holes are provided on the side of the limit tube, and each through hole is connected to a suction pipe. A negative pressure suction unit is installed inside the support box, and the negative pressure suction unit is provided with suction pipes connected to each through hole. An air inlet corresponding to the negative pressure suction unit is provided in the support box. A frame is provided at the top of the support box, and a second telescopic mechanism corresponding to the circular hole is provided on the frame. A pressure sensor is provided at the lower end of the second telescopic mechanism, and an annular pressure block is detachably installed at the lower end of the pressure sensor. A controller connected to the pressure sensor is provided on the support box, and the controller is connected to a display.

[0006] Preferably, both the first telescopic mechanism and the second telescopic mechanism are hydraulic telescopic rods, and a hydraulic station connected to both the first telescopic mechanism and the second telescopic mechanism is provided inside the support box.

[0007] Preferably, the circular plate has an annular groove on its side, and a rubber sealing ring is installed in the annular groove.

[0008] Preferably, the circular plate has a threaded hole at its center, and a limit post is threadedly connected to the upper end face of the circular plate.

[0009] Preferably, the upper end face of the limiting post is chamfered.

[0010] Preferably, the side of the limiting post is provided with anti-slip texture.

[0011] Compared to existing technologies, the advantages are:

[0012] In the process of strength testing, if the ceramic sealing ring breaks, after removing the large pieces of debris, the first telescopic mechanism controls the circular plate to descend below the through hole, activates the negative pressure dust collection unit, and uses the dust collection pipe to suck away the debris. Then, the circular plate is controlled to reset, which facilitates cleaning of the debris and keeps the strength testing device clean. Attached Figure Description
