通过拆解漏浆轴端件,发现了浮封环上O形圈发生脱落、被切断和挤压变形是造成密封失效的主要原因。通过试验证明,浮封环上的O形圈的最大承压能力是5MPa。
By disassembling the leakage shaft end pieces, it was found that the floating ring O-ring shedding, was cut off and squeeze deformation is the main reason for seal failure. Proved through experiments that the maximum pressure capacity of the o-ring on the floating ring is 5MPa.
