What are the characteristics of rotary, co-stop, internally mounted mechanical seals and exterior-mounted seals?

1. what are rotary and co-stop mechanical seals

According to the motion of the elastic components of the compensation mechanism, mechanical seals water pump seals can be divided into rotary and static mechanical seals. The compensation mechanism that rotates with the shaft is called a rotary mechanical seal: a non-rotating (installed in the gland) is called a static mechanical seal. When the compensation mechanism rotates, it is easy to produce a quality that does not equilibrate, and at the same time consumes stirring power, so the rotary seal cannot be used for high speed; while the static seal can be used for high speed. However, rotary seal installation is more convenient. Therefore, common mechanical seals mostly adopt a rotary structure.

2. what are the differences between interior and exterior seals?

According to the mechanical seal installation position of the stationary ring can be divided into built-in and external mechanical seal. The mechanical seals of the static ring mounted on the inside of the seal gland (or the part corresponding to the seal gland) (namely the side facing the working chamber of the host machine) is called the built-in mechanical seal. On the other hand, when the static seal is installed on the outside of the seal gland, it is called the external seal. Mechanical seals.

internally mounted mechanical seals can be used for high temperatures and pressures, as well as media that do not corrode the moving ring and elastic elements. Externally mounted mechanical seals for low pressure (or negative pressure) and corrosive media.
