Description

Splash-proof self-sealing lubricating oil filling device Technical Field The invention relates to the technical field of equipment operation and maintenance in coal bed methane development engineering, in particular to an anti-splashing self-sealing lubricating oil filling device for a coal bed methane supercharger. Background In the long-distance storage and transportation link of coal bed gas development, the coal bed gas is required to be pressurized step by step through a multi-stage supercharger to ensure the coal bed gas conveying efficiency and the system operation stability, and the crude oil separator is used as a core matching component of the supercharger and is required to be filled with lubricating oil periodically to maintain the normal operation of equipment. According to the operation and maintenance specifications of the coalbed methane supercharger, the supercharger is required to be continuously operated for 167 days to carry out lubricating oil filling maintenance operation, the conventional funnel type filling mode is adopted in the existing operation, and manual filling operation is required to be carried out on an oil filling port of the crude oil separator. Firstly, the coalbed methane supercharger and the coarse oil separator are easy to remain high-pressure gas, if the pressure is not completely relieved and discharged before filling, when the liquid level of lubricating oil floods an oil filling port, the residual gas in the interior is rapidly compressed and then instantaneously ejected out to cause the splashing of the lubricating oil; the lubricating oil filled in the field is usually at the middle Wen Youye of 40-60 ℃, splashed oil is easy to cause scalding injury to operators, and the oil splashes to pollute field equipment and the environment, so that the later cleaning cost is increased. Secondly, the field station has complex field environment, dust, metal chips and other impurities are easy to mix in the lubricating oil to be filled, the conventional funnel type filling has no filtering link, and after the impurities enter the coarse oil separator along with the lubricating oil, the impurities can circularly invade core components such as a bearing, an impeller and the like of the supercharger along with the lubricating oil, so that the components are worn, stuck and even irreversibly damaged mechanically, the service life and the operation safety of the supercharger are seriously influenced, and the operation and maintenance cost and the failure shutdown rate of the equipment are increased.
