Title (EN) SEAL SYSTEM
(FR) SYSTÈME D'ÉTANCHÉITÉ
(JA) シールシステム
Abstract:
(EN) This seal system is provided with: a double mechanical seal including a pump-side sealing mechanism (10, 12) and an atmosphere-side sealing mechanism (11, 13); a pump mechanism (19) driven by a rotating shaft (1); a first medium circulating line (30) which is connected to a first chamber (22a) and a second chamber (22b) and which causes a fluid barrier and cooling medium different from a fluid being handled by a centrifugal pump to circulate between the first chamber (22a) and the second chamber (22b); a heat exchanger (21) and a shutoff valve (28) attached in the first medium circulating line (30); a second medium circulating line (31) which bypasses the shutoff valve (28); and a medium pressure pump (45) and an open/closed valve (23) attached in the second medium circulating line (31).
(FR) La présente invention concerne un système d'étanchéité pourvu: d'un joint d'étanchéité mécanique double comprenant un mécanisme d'étanchéité côté pompe (10, 12) et un mécanisme d'étanchéité côté atmosphère (11, 13); d'un mécanisme de pompe (19) entraîné par un arbre rotatif (1); d'une première conduite de circulation de fluide (30) qui est reliée à une première chambre (22a) et à une seconde chambre (22b) et qui fait circuler une barrière de fluide et un fluide de refroidissement différents d'un fluide manipulé par une pompe centrifuge, entre la première chambre (22a) et la seconde chambre (22b); d'un échangeur de chaleur (21) et d'une soupape d'arrêt (28) fixés dans la première conduite de circulation de fluide (30); d'une seconde conduite de circulation de fluide (31) qui contourne la soupape d'arrêt (28); et d'une pompe à pression moyenne (45) et d'une soupape ouverte/fermée (23) fixées dans la seconde conduite de circulation de fluide (31).
(JA) シールシステムは、ポンプ側シール機構(10,12)および大気側シール機構(11,13)を有するダブルメカニカルシールと、回転軸(1)により駆動されるポンプ機構(19)と、第1チャンバ(22a)と第2チャンバ(22b)とに接続され、遠心ポンプの取り扱い流体とは異なる流体バリア兼冷却媒体を第1チャンバ(22a)と第2チャンバ(22b)との間で循環させる第1媒体循環ライン(30)と、第1媒体循環ライン(30)に取り付けられた熱交換器(21)および遮断弁(28)と、遮断弁(28)をバイパスする第2媒体循環ライン(31)と、第2媒体循環ライン(31)に取り付けられた媒体加圧ポンプ(45)および開閉弁(23)とを備える。
