Compressor crankcase breathing hole leak above the technical report

The compressor crankcase above technical report 2020 - hole leakage, breathing 01 - 30 Lv Yiqiong ( Henan vertical and horizontal gas pipeline co. , LTD. ) Compressor is important production equipment, our company is the core component of the compressor crankcase. Crankcase above breathing hole cannot be blocked, and the main role to balance the crankcase pressure inside and outside, breathing hole should keep clear of blowhole ventilation, avoid to form internal and external pressure imbalance. , the existence problem of compressor running for many years, the company safety inspection or two from the daily inspection, are multiple compressor oil too many questions. Through observation and analysis of multiple, crankcase heat generated in the process of movement, heat oil gasification, breathing breathing hole, spewed into the crankcase outside, the main source for the equipment surface oil. Oil to the compressor parts, with long-term operation, the surface oil pollution is piling up, difficult to clean up, also caused the part of the waste. Rectification effect: before the solution is in the breathing hole filled steel wire ball, play a little, in order to guarantee the breathing hole is not blocked, so has been didn't find the right solution. In two years, I work through the company's training, the teaching of the leadership, the team's assistance, query information and discuss with related technical professionals, to try again to this question for technical improvement. Observation equipment operation, after the completion of the rectification since 1 month, I found that the compressor running after a few days in a row, on the crankcase and only a thin layer of oil mist, use simple cha once clean cloth, ultimately determine the improvement is successful. Rectification success means not only saves mother station staff labor, also made some contribution to energy saving and emission reduction for the company. Four, three, comparison before and after the rectification: rectification technology summary: corrective breathing hole parts before the crankcase attaches only one layer of aluminum plate with 5 mm hole sealing, small aluminum plate hole, there are far too few, sometimes only one, crankshaft will take up a part of the oil, because of the aluminum plate hole is small, the oil will stay on the aluminum plate, at the same time due to breathing is not smooth, high temperature to form a certain pressure difference, plus vibrations in increased oil and aluminium plate, oil can not be timely into the crankcase, pouring down from above the blowholes. Find out why, after I bold attempt a solution with the team, the increase in the number of drill to expand the original aluminum plate with 10 mm to 5 - 6 and 2 - before and after the increase 3 mm thick asbestos mat, because there is no special asbestos pad to tap production, fixed before using tools on aluminum plate let its semicircle concave shaped hole, in order to reduce the amount of oil reservoir, reduce vibration, reduce the pressure difference, add a few steel ball inside to prevent foreign bodies fall into the crankcase, then cover the breathing hole, be careful not to tighten the guarantee ventilation, since it can achieve the desired effect. The rectification work looks be like simple, but after the success, more incentives in our daily work backwards, active learning, dare to try, bold innovation, also reflects the value of our maintenance personnel.
