The invention provides a no-mouthpiece pipeline connecting device used for washing a gas turbine bearing cavity. The no-mouthpiece pipeline connecting device comprises an installing disc and an oil receiving nozzle. The oil receiving nozzle is installed on the installing disc in an inserted manner. According to the specific inserting installation manner, the oil receiving nozzle penetrates an oilreceiving nozzle installing hole in the installing disc and is connected with an adjusting nut through a thread on the side wall of the oil receiving nozzle, the adjusting nut is fixed below the installing disc through a limiting disc and a screw, the limiting disc is clamped between the adjusting nut and the screw and has the function of restraining the adjusting nut from moving up and down, theside portion of the installing disc is further provided with a limiting pin, the limiting pin is clamped into a groove in the side face of the oil receiving nozzle and has the function of further preventing the oil receiving nozzle from rotating, by rotating the adjusting nut, the oil receiving nozzle only moves in the vertical direction, and the bottom of the oil receiving nozzle is further provided with a connector used for installing flushing equipment. The no-mouthpiece pipeline connecting device can achieve pressure flushing of the gas turbine bearing cavity.
Description
technical field [0001] The invention relates to a pipeline connection device, in particular to a nozzleless pipeline connection device for cleaning a gas turbine bearing cavity. Background technique [0002] After the gas turbine was overhauled and put into operation again, the oil return temperature of the lubricating oil was too high and the vibration of the gas turbine exceeded the limit. When returning to the factory for disassembly and inspection, it was found that the bearings were severely worn, and there was a large amount of sludge and dirt in the bearing cavity of the high-pressure turbine rotor. After analysis, the cause of the failure may be that the oil supply pipe of the bearing cavity is narrow, which is easily blocked by sludge and dirt, causing lubricating oil Insufficient oil supply leads to poor bearing lubrication and severe bearing wear, resulting in high lubricating oil return temperature and excessive vibration of the gas turbine. For this reason, the...
