Have you ever used a magnetic mechanical seal?
Thread Content
I was reading a book recently that mentioned magnetic mechanical seals. Fellow sailors, has anyone come across them? Are there any relevant pictures? Or related instructions or something; I searched on Baidu but couldn’t find any specific ones. There is a reward for those who can provide relevant information.
A mechanical seal that uses magnetic force instead of elastic force for compensation.
I suggest you take a look at the information on this magnetic pump; I hope it will be helpful to you. http://baike.baidu.com/link?url=B7xsfD8uEbUODTGHFhbeE7krtRgFeUxWzJgKUwq94MIXgvBnwipESvUw0pVYMQGWdPB8LnBbxt73xqZHiV2ySq
What I need is a magnetic mechanical seal; we have several magnetic pumps here
What kind of seal is used in magnetic pump, and what is the principle of sealing?
You’ve misunderstood; it’s not a mechanical seal for the pump.
The medium-side seal of the magnetic pump is a static seal, while the bearing housing side is equipped with a mechanical oil seal; our factory has replaced this with a small threaded groove on the gland.
A magnetic mechanical seal separates the inside and outside of the container with steel plates, and the rotation of the stirring shaft is driven by magnetism between the inner and outer discs.
I’ve never come across it. The purpose of sealing is to prevent leaks; so, the so-called magnetic sealing must involve the use of a seal ring to isolate the medium, with no moving seal elements – that’s probably the principle behind leak-free magnetic pumps, in my opinion.
It essentially replaces the elastic element used in mechanical seals with magnetic attraction for use as an oil seal in bearing housings; however, few companies use it, and it is somewhat expensive
