Description

Technical Field

[0001] The present application relates to the technical field of hydrogen measuring probe processing, and more specifically, to a special tooling for manufacturing hydrogen measuring probes. Background Art

[0002] Hydrogen damage to metal equipment and pipelines used in the field of oil and gas development is mainly caused by acidic gases in natural gas. Excessive hydrogen content in metals can lead to material failure forms such as cracking and fracture, causing ecological harm and industrial safety threats. It is necessary to conduct real-time corrosion monitoring of pipelines and other equipment used in petrochemical plant production. For example, monitoring of hydrogen flux is crucial to the economic operation and maintenance of process equipment. The porous ceramic head used in the hydrogen measuring probe needs to be filled with a special paste-like material.

[0003] When hydrogen measuring probes are poured into paste materials, it is usually necessary to manually hold a clamp and position and pour a single probe, which makes the pouring process time-consuming and labor-intensive, and the efficiency of hydrogen measuring probe production is not high enough. Therefore, in order to solve such problems, we propose a special tooling for hydrogen measuring probe production. Utility Model Content

[0009] Preferably, the clamping groove wall of the clamping block is provided with a rubber layer.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] By installing the supporting plate, multiple hydrogen measuring probe capillaries are respectively inserted into adjacent porous ceramic heads and placed in the clamping groove of the clamping block. The driving mechanism cooperates with multiple scissor arms to drive multiple sliders to slide synchronously and equidistantly between the two support rods. Multiple clamps simultaneously reduce the spacing to fix the hydrogen measuring probe capillary, and the paste-like special material is sent from the hydrogen measuring probe capillary into the porous ceramic head. After the porous ceramic head paste is fixed, the driving mechanism cooperates with multiple scissor arms to drive multiple sliders and clamps to increase the spacing, and remove multiple groups of porous ceramic heads and hydrogen measuring probe capillaries. It has a synchronous positioning structure for multiple ceramic heads and improves the perfusion efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
