Problems solved by technology

However, in the actual ceramic preparation process, it is difficult to avoid the introduction of various impurities and defects. For the finished tubular ceramic materials, there is no suitable strength testing method in China at present. It can only be made into samples for testing or destructive testing of finished products, which cannot be reasonably tested. Quantitative screening of ceramic tube products

Abstract

The invention discloses a device used for detecting the pressure resistance of a ceramic tube. The device used for detecting the pressure resistance of the ceramic tube comprises a box body, a testing clamp and a pressurization system, wherein the upper part of the box body is provided with a testing cavity; a base and a frame are arranged in the testing cavity; the base is arranged on a bottom plate of the testing cavity; the frame is in a U-shaped structure and is fixed at the upper end of the base; the upper parts of two side arms of the frame are respectively provided with a bearing; a threaded through hole is formed in the center of the bottom wall of the frame; a screw rod and a nut are connected to the threaded through hole; the testing clamp is movably connected to the frame through the bearings and can be fixed through the screw rod and the nut; and the pressurization system is connected to the testing clamp. The device disclosed by the invention can meet the testing requirements of static-pressure resistance and burst pressure resistance of various types of ceramic tubes, the testing and screening can be rapidly and accurately performed, the defective ceramic tubes are removed, and the strength of ceramic tubes in batches is guaranteed.

Description

technical field [0001] The invention relates to pressure-resistant testing equipment for ceramic tubes. Background technique [0002] With the rapid development of technology and economy, ceramic tube products for certain special functional applications, such as β-alumina electrolyte ceramic tubes for sodium-sulfur batteries, zirconia ceramic tubes for fuel cells, coke oven gas by-product oxidation reforming hydrogen production equipment The market demand for BCFN (a synthetic special polycrystalline compound) oxygen-permeable membrane composite dielectric ceramic tube and so on is increasing. The general characteristics of these special ceramic tubes: First, the required products are thin-walled, one end is closed and the other end is open, and the length-to-diameter ratio is greater than 5; second, the environmental requirements for ceramic tube applications are high, and generally work at medium and high temperatures and need to be repeated. The temperature rises and fal...
