德國BURKERT電磁閥閥門泄露的焊接加工步驟原理有哪些?
德國BURKERT電磁閥*種情況是:臟物雜質(zhì)落到密封面上,將密封面墊住,造成閥芯與閥座間有間隙,從而閥門滲漏。消除這種故障的方法就是清除掉落到密封面上的臟物及雜質(zhì),般在鍋爐準(zhǔn)備停爐大小修時,做安全門跑砣試驗,如果發(fā)現(xiàn)漏泄停爐后都進(jìn)行解體檢修。如果是點爐后進(jìn)行跑砣試驗時發(fā)現(xiàn)安全門漏泄,估計是這種情況造成的,可在跑砣后冷卻20分鐘后再跑舵次,對密封面進(jìn)行沖刷。二種情況是密封面損傷。造成密封面損傷的主要原因有以下幾點:是密封面材質(zhì)不良。目前使用YST103通用鋼焊條堆焊加工的閥芯密封面效果就比較好。二是檢修差,閥芯閥座研磨的達(dá)不到標(biāo)準(zhǔn)要求,消除這種故障的方法是根據(jù)損傷程度采用研磨或車削后研磨的方法修復(fù)密封面。閥門泄露的焊接加工。
以下是參考譯文:
The first kind of circumstance is: dirt to seal surface impurities, the sealing surface mat, causing a gap between valve core and valve seat, valve leakage. Method of eliminating the fault is cleared dropped a seal surface dirt and impurities, general big improvements in boiler for boiler stop, first do exit lead test run, if leakage is found after the furnace for overhauling. If it is a point after the furnace leakage found in testing the run lead the security, estimation is caused by this kind of situation, can be in running tuo cooling after 20 minutes after rudder, scour on sealing surface. The second is the sealing surface damage. The main reason for the sealing surface damage has the following points: one is the bad sealing surface material. Currently using YST103 general steel electrode welding processing of valve core sealing surface effect is good. Second, poor quality of maintenance, the valve core seat grinding can not meet the quality standard requirement, method of eliminating the fault according to the damage degree are grinding or turning the sealing surface grinding of repair methods
