What are the four sealing points of a pump mechanical seal? Answer: 1. Between the pump body and the gland. 2. Between the static ring and the gland. 3. Between the rotating ring and the stationary ring. 4. Between the moving ring and the shaft or bushing. http://down.hcbbs.cc/attachment/forum/201706/10/203353z7y06fdo70r6eod0.jpg Petrochemical Zone — “Creative Ideas for Energy Savings”: The Second Round of This Activity Is in Full Swing http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=1666758 (Source: Haichuan Chemical Forum) “My Technical Upgrades” in the Field of Coal Chemicals in 2017 http://bbs.hcbbs.com/thread-1786290-1-1.html (Source: Haichuan Chemical Forum Website) First Round of Voting for the Best Electronic Book Reviews on Haichuan Forum — Chance to Win Prizes by Participating in Voting (For members of the Management and Technology Group and those in Grade 5 or above) http://bbs.hcbbs.com/thread-1799455-1-1.html (Source: Haichuan Chemical Forum Website)
Between the pump body and the gland, between the stationary ring and the gland, between the rotating ring and the stationary ring, and between the rotating ring and the shaft or sleeve
①Mechanical seals generally have four sealing points. ②Three of these static seals (the joint between the gland and the housing, between the static ring and the gland, and between the dynamic ring and the shaft sleeve) are sealed by using additional gaskets or sealing rings. ③A dynamic seal achieves sealing by the tight fit between the end surfaces of the dynamic and static seal rings.
1. Between the pump body and the gland. 2. Between the static ring and the gland. 3. Between the rotating ring and the stationary ring. 4. Between the moving ring and the shaft or bushing.
1. The sealing point between the stationary ring and the end face of the gland; 2. The sealing point between the rotating ring and the shaft or sleeve; 3. The sealing point between the gland and the pump casing or other equipment; 4. The sealing point where the end faces rotate relative to each other. Generally, it consists of four components: the primary seal, the auxiliary seal, the compensation mechanism, and the transmission mechanism.
1). Between the pump body and the gland. 2). Between the static ring and the gland. 3). Between the moving ring and the stationary ring. 4). Between the moving ring and the shaft or bushing.
