在较高的排气压力下,对于无润滑活塞密封工作能力所进行的研究,说明非金属环运转过程具有许多特点。对于排气压力达400公斤力/厘米2下无润滑活塞密封工作能力的研究,是在列宁格勒加里宁工程学院的一台闭合线路内运转的十字头式增压压缩机的各级上进行的。试验工作台和测量方法在参考文献[1]内有所叙述。增压级的活塞直径为30毫米,是装配式的,上有截面为5×5毫米的密封环及弹力环和两根具有减荷沟槽的剖分式支承环。密封
At higher discharge pressures, studies on the ability of non-lubricated piston seals to work demonstrate the many characteristics of non-metallic ring operation. The study of the capability of a non-lubricated piston seal for an exhaust pressure of up to 400 kgf / cm 2 was performed on all stages of a crosshead booster compressor operating in a closed circuit at the Kaliningrad Engineering College, Leningrad of. The test bench and measurement methods are described in reference [1]. The supercharged piston, 30 mm in diameter, is preassembled with a 5 x 5 mm section seal ring and elastic ring and two split support rings with relief grooves. seal
