Piston thin oil sealing gas cabinet for splashing-prevention oil supply

Abstract

The invention discloses a piston thin oil sealing gas cabinet for splashing-prevention oil supply, comprising a cabinet body, a piston and an oil supply device, wherein the piston is arranged in the cabinet body; and an overflowing port for overflowing sealing oil of the oil supply device to the inner side of a side plate of the cabinet body and flowing the sealing oil into an oil groove of the piston is arranged on the side plate of the cabinet body, the inner surface of the side plate of the cabinet body is provided with a strip-shaped slow-flow oil distributing weir, along a transverse direction, opposite to the overflowing port and between the upper dead center of the piston and the overflowing port, the strip-shaped slow-flow oil distributing weir comprises a slow-flow oil distributing tank or / and a slow-flow oil distributing bulge arranged on the inner surface of the side plate of the cabinet body, and the length of the strip-shaped slow-flow oil distributing weir is greater than the transverse distributing width of the overflowing port along the side plate of the cabinet body. The piston thin oil sealing gas cabinet can redistribute the sealing oil through the overflowing weir effect of the slow-flow oil distributing weir to increase the oil distributing width, and reduce the flow speed under the condition of not influencing the oil supply quantity so that the sealing oil slowly flows along the inner side of the side plate, thereby reducing and even eliminating the phenomenon that the sealing oil splashes and spills; and the thin oil sealing dry gas cabinet can safely and smoothly run and has the advantages of convenient maintenance and better environmental protection.

Description

technical field [0001] The invention relates to a thin-oil-sealed piston gas cabinet, which includes a thin-oil steel slide-sealed gas cabinet (man-type cabinet) and a thin-oil rubber-sealed gas cabinet (new cabinet or POC cabinet). Background technique [0002] The gas cabinet is a steel container for storing industrial and civil gas. Because it holds gas, it has high requirements for its sealing performance. In the prior art, thin oil-sealed piston-type dry-type gas holders are commonly used. The thin-oil-sealed dry-type gas holders in the gas holder continuously supply sealing oil to the piston oil groove by means of closed-circuit forced circulation of sealing oil. Keep the height of the oil groove oil seal to prevent gas from escaping. The oil supply device includes an oil supply pump and piping, a reserve oil tank, an overflow device, and an oil collector on the piston, which together form the piston seal oil supply device to form the piston oil channel oil supply sys...

Problems solved by technology

[0004] However, since the gas cabinet is a large-scale field device, due to the limitation of the structure, the width of the oil distribution is limited by the position of the column. During the flow of the sealing oil, due to the uneven distribution of the flow, the part with a large flow often breaks away at the uneven part of the side plate. On the inner wall of the side plate, the size and speed of the oil droplets are not uniform, causing the oil droplets to collide with each other and aggravate the splashing. After falling tens of meters high, they will fall to a place other than the oil collecting plate on the piston.

The sealing oil floats to the piston, causing uneven piston quality and inclined operation, threatening the safe operation of the equipment, and the fluctuation of the gas storage pressure of the gas cabinet will also increase; the loss of sealing oil must be recovered manually, which is difficult to work
