["Pourquoi la pompe ne peut-- sortir de de pression?Le vidage est-il normal?Les entrées et sortuss sont-- normales?La fuite de la jointureureait--influencer la pression de sortu?"

"Si si la joint joint fe fuit,肯定不会影响er la press pression à la sortie"
Reply #32017-12-15
"Si la pression ne ne sort obtenir,应该 check le sens de rotation du moteur,叶轮是否 obstré?Joint joint fe f reux可能 ne affect la débit?"
Reply #42017-12-15
"不影响。比如你 démarres la pompe,打开个出口管上的六分放空阀一样,不会影响。"
Reply #52017-12-15
"La fuite de la joint joint joint nee ne affect pas beaucoup la press pression à la sortie,应该另找原因!比如叶轮键是否松脱,泵进出口工况是否正常......"

"La joint joint joint est un lubrifiantant et无关紧要,容易磨损轴承"

"本帖最后由 156266 于 221-5 16:42 编辑 跟密封漏关系不是太大吧。会不会叶轮被冲蚀了?我之前有一台多级泵,就是因为叶轮隔板等部件被冲蚀了,导致压力打不上来来。我当时那台泵也是打水,锅炉给水泵。既然你说外部各类都没问题,我觉得只有拆修泵,解体看看是不是内部问题了。反正你正好密封漏要更换密封。哈哈"

"什么泵?如果是离心泵,往复泵会影响,离心式看漏的程度,严重了也会影响。"

"现在是泵出口压力正常,母管油压正常,控制油压力高,二次油压高高,速关油压高,如果把回油阀开大、二次阀开大、把控制油压力降下来就好了"
Reply #102017-12-15
"电机是否转向、叶轮是否堵塞、脱落?密封稍微有点泄漏应该没问题。"
Reply #112017-12-15
"你这问题是让我们猜?我真的猜不到!"
Reply #122017-12-16
"进出口有没有堵住?有没有阀门没开?转向是否正确?有没有气蚀?回流管是否开得太大?"
Reply #132017-12-16
"到底是什么泵?怎么又出现汽轮机的控制油、二次油了???"
Reply #142017-12-16
"他错地方了,他动设备板块问汽轮机油压问题来"
Reply #152017-12-16
"我还纳闷了好久。。。哈哈"
Reply #162017-12-17
"按楼主表述,进出口压力正常,怎么会打不上压力呢?"
Reply #172017-12-17
"如果密封漏量大,会影响出口压力。漏量小对出口压力基本无影响。你不起压是不是过滤器不畅,或是叶轮脱落还有就是开泵时灌泵是否正确"
