The Application Of The Agitator Seal
Jul 05, 2017

The agitator seal is a rotary oil seal device. Such as centrifugal pumps, centrifuges, reactors and compressors. As the drive shaft penetrates inside and outside the equipment, there is a circumferential gap between the shaft and the device, and the media in the equipment leaks out through the gap. If the pressure in the equipment is below atmospheric pressure, the air leaks into the equipment, Agitator Seals so there must be a To prevent leakage of the shaft seal device. Many types of shaft seals, because the agitator seal with less leakage and long life, etc., so the world today, the mixer is the main seal in these devices seal the way. The agitator seal is also called an end seal and is defined in the relevant national standard: "By at least one pair of faces perpendicular to the axis of rotation, the action of the fluid pressure and the resilient force (or magnetic force) of the compensating mechanism and the auxiliary seal A device that prevents the fluid from leaking.

Seal is divided into: packing seal, stirrer seal, enamel seal

The stirrer seal can be divided according to the pressure: 1) single end agitator seal 2) double end agitator seal

Single End: 202 Single End Face Unbalanced Stirrer Seal, Agitator Seals 204 Single End Balanced Stirrer Seal, 212 Single End Balanced Stirrer Seal.

Double end face unbalanced agitator seal, 222 double end face unbalanced agitator seal, 205 double end unbalanced agitator seal, 206 double end face balanced type agitator seal .207 double end balance type agitator seal , 2000 double end face agitator seal, 2002 double end face agitator seal, 2004 double end face agitator seal, 2005 double end face agitator seal, 2009 double end face agitator seal, 2010 double end face agitator seal, Agitator Seals 2011 double end agitator seal, 2012 double end face agitator seal.

Enamel Seal: 1) Type 212 Enamel Mixer Seal 2) 221 Enamel Mixer Seal

The classification and introduction of the agitator seal

Single end:

202 single-end unbalanced agitator seal: operating temperature 0-150 ℃, the pressure range -0.0025-0.25Mpa. Features and applications - simple mechanism for general sealing. When using the temperature> 60 ℃, you need to use the cooling water jacket forced cooling.

204 single-end balance type mixer seal: operating temperature 0-150 ℃, the pressure range of 0-0.6Mpa. Features and applications - simple mechanism for general sealing. When using the temperature> 60 ℃, you need to use the cooling water jacket forced cooling.

212 single-end balance type mixer seal: operating temperature -10-120 ℃, the pressure range of 0-0.6Mpa. For corrosion-resistant, no suspended solids, the general requirements of the occasion sealed. Particularly suitable for glass-lined reactor and radial swing large sealed occasions.

Double end face:

221 double end unbalanced agitator seal: operating temperature 150 ℃, pressure range 0-1.0Mpa. Suitable for axial size limited workplace, can withstand strong corrosive media, can be used for glass-lined reactor. When the temperature exceeds 120 ℃, Agitator Seals the need to set the cooling water tank. When using a pressure greater than 0.6Mpa, use a pressure equalizer.

222 double end unbalanced agitator seal: operating temperature 150 ℃, pressure range 0-1.0Mpa. Applicable to the axial size of the limited workplace, can withstand weak corrosive media, can be used with stainless steel reactor supporting. When the temperature exceeds 120 ℃, the need to set the cooling water tank. When using a pressure greater than 0.6Mpa, use a pressure equalizer.
