Who knows how many types of machine seals there are
Thread Content
Who has all the seal model numbers? How many types of seal models are there? Scope of application. Do every manufacturing plant have different standards?
Yes, there are many standards and various models, and new ones are continuously being developed to meet production needs.
According to the API682-2014 standard, flushing schemes can be roughly divided into 32 types based on the differences in sealing flushing methods. These include: single-seal schemes: plan01, plan02, plan03, plan11, plan12, plan13, plan14, plan21, plan22, plan23, plan31, plan32, plan41. Dual-seal options: plan51, plan52, plan53A, plan53B, plan53C, plan54, plan55. Quenching plans: plan61, plan62; (plans such as plan65A, plan65B, plan66A, plan66B are leakage collection plans). Dry gas seal (or dry running seal): plan71, plan72, plan74 (contactless dry gas seal), plan75, plan76. Special seal: plan99
All seals are manufactured in accordance with API682; by looking at the type of seal, it’s possible to estimate roughly how many different types of seals exist!
Mechanical seal numbers vary from manufacturer to manufacturer, so it’s not possible to make generalizations!
There are too many mechanical seal models, and it’s very confusing【each manufacturer develops its own ones】. The manufacturers of different series of national standards vary, and there are also differences among them
Different manufacturers use different approaches; they assign their own model numbers, and there are also slight differences in structure. Therefore, the mechanical seals produced by different manufacturers are not interchangeable. Do you understand why?
This question is too broad. . . . . PS, the OP’s amazing ID
