2results about How to "Reliable drying" patented technology

This utility model discloses an associated gas drying device for oil wells, comprising a cylindrical shell with a solid adsorption layer in the middle of the shell's inner cavity. Circular perforated plates are installed at the top and bottom of the solid adsorption layer. A main shaft is located at the center of the bottom of the shell's inner cavity, and is fixedly connected to the two perforated plates. The bottom end of the main shaft is connected to a stepper motor via a coupling. A sleeve passes through the main shaft, and two lower partitions are fixedly connected to both sides of the sleeve. The two lower partitions divide the bottom of the shell's inner cavity into symmetrically arranged associated gas distribution chambers and humid air accumulation chambers. An upper partition is fixedly installed at the top of the shell's inner cavity, dividing the top of the shell's inner cavity into symmetrically arranged associated gas accumulation chambers and hot air distribution chambers. The associated gas drying device for oil wells provided by this utility model can achieve continuous production, ensure stable gas supply, and avoid pressure fluctuations or temporary interruptions due to bed switching.

The utility model relates to the technical field of cable joints, and discloses a cable intermediate joint with a waterproof structure, which comprises a butt joint body, cable bodies are mounted at the left end and the right end of the inner wall of the butt joint body, and fixing heads are fixedly connected to the left end and the right end of the butt joint body. A fixing steel ball is connected to the outer wall of the fixing head through an extrusion set, a connecting shell is fixedly connected to the outer wall of the top end of the butt joint body, a pressing cover is slidably connected to the outer wall of the connecting shell, an air inlet groove is formed in the top end of the pressing cover, an inflation pump is installed at the bottom end of the pressing cover, and an annular air bag is connected to the output end of the inflation pump through a sealing set. According to the utility model, moist air is effectively blocked, the waterproof performance is significantly improved, the dryness and reliability of the joint are ensured, the stability of the cable is significantly enhanced through rigid fixation, displacement and loosening are effectively prevented, and the reliable connection is ensured.
