Problems solved by technology
Since the piston sealing device on the piston steel structure is adjacent to the lever weight mechanism, the size of the hole for personnel to enter and exit is ~600mm (length) × ~370mm (width), and the root of the spring and the support rod in this patent must avoid the lever weight The mechanism occupies the hole area for personnel to enter and exit, resulting in a narrow passage for personnel to enter the piston oil groove; if the length of the hole here is increased, the force compression system of the piston sealing device and even the stiffness of the sealing rubber will have to be redesigned, and the amount of change will be large. And the sealing effect is reduced
Moreover, the oil-scraping rubber is always attached to the side plate, and the oil-scraping rubber has a long working time and a short service life

Embodiment Construction
[0020] The oil scraping device for the side plate of the cylindrical gas tank of this embodiment includes an oil scraper 1 and a support rod 2. One end of the support rod 2 is connected with the oil scraper 1 and the other end is connected to a lifting beam fixed on the gas tank piston 3 4 is hinged, the support rod 2 can rotate around the hinged axis gas tank side plate 5 and press the oil scraper 1 against the gas tank side plate 5 under the action of gravity, the support rod 2 can also rotate around the hinged axis The side of the gas tank piston 3 rotates to separate the oil scraper 1 from the side plate 5 of the gas tank.
[0021] When the temperature is low, the viscosity of the sealing oil is greater, and more sealing oil will adhere to the side plate when the piston moves down. In this situation, push the support rod 2 to rotate to press the oil scraper 1 on the side plate 5 of the gas tank. The oil scraper 1 can scrape the sealing oil attached to the side plate to flow b...

Provided is a cylindrical gas holder side panel oil scraper apparatus, comprising an oil scraper piece and a support rod. One end of the support rod is connected to the oil scraper piece, while the other end is pivotally connected to a lifting beam fixed onto a gas holder piston. The support rod is allowed to rotate around a pivot shaft towards a gas holder side panel and under the effect of gravity makes the oil scraper piece to be pressed against the gas holder side panel. The support rod is also allowed to rotate around the pivot shaft towards the gas holder piston side and makes the oil scraper piece to be detached from the gas holder side panel. The cylindrical gas holder side panel oil scraper device is capable of using the oil scraper piece leaning against the gas holder side panel to scrape off sealing oil attached onto the side panel to ensure the height of oil level in a piston oil groove; at high temperatures, the oil scraper piece detaches from the side panel and falls towards the piston side, and the oil scraper apparatus ceases to operate thereby extending the service life of the oil scraper apparatus; while at the same time, the oil scraper apparatus is provided between the gas holder side panel and the lifting beam, the oil scraper apparatus neither interferes with nor narrows an inspection channel between the lifting beam and the piston.
Description
Technical field [0001] The invention relates to a cylindrical gas holder, in particular to a side plate oil scraping device of the cylindrical gas holder. Background technique [0002] Cylindrical cabinet is a kind of dry gas cabinet with cylindrical shape. Its piston is sealed with thin oil and strip rubber product sealing device. In the past ten years, more than 50 units have been built in China, with a total investment of more than 20 100 million yuan. At present, the piston speed of the cylindrical cabinet can reach 3m / min, but compared with the rubber membrane sealed gas tank with the piston speed as high as 7m / min, the piston running speed of the cylindrical cabinet is still low. Therefore, how to improve the cylindrical shape The running speed of the cabinet piston has always been a frontier issue in the industry. [0003] Cylindrical cabinet is a kind of thin oil sealed gas cabinet. Its sealing device is composed of sealing rubber strip, rubber clamping mechanism, suspens...
