                                        閥門PR2試驗失敗的4大原因

                                        2018-10-19 0

                                        閥門PR2性能鑒定試驗失敗的原因主要有以下4個:

                                        1、閥桿密封件低溫泄漏,是因為選用的密封件達不到最低溫度要求;

                                        2、閥座密封圈的損壞,說明閥座密封圈抵抗不了溫度變化和密封壓力的雙重作用;

                                        3、閘板、閥座的輕微劃傷,說明閘板、閥座的表面處理硬座選擇不合理,船用鍛鋼閥門在常溫、高溫和低溫多次循環后,造成表面輕微劃傷;

                                        4、扭矩太大,說明閥桿和閥桿螺母的摩擦系數過大,填料與閥桿之間摩擦系數過大,減磨措施不良。
