221 type radial double end mechanical seal
Specification: 50L-30000L
Scope of use
Pressure: 221 type absolute pressure 9.87 × *10-2 gauge pressure 1.0MPA Temperature: inside the sealed cavity ≤ 80 ℃, inside the reactor -20~200 ℃
Linear speed: 2m/s Working conditions: flammable, explosive, toxic, strong corrosive gas
Structural features:
The installation dimensions conform to HG2057-91 "Glass- lined stirrer mechanical seal " and HG/T2052-91 " Glass- lined equipment transmission".
This product has a radial double-end and a static structure. Due to the isolation air flow (sealing liquid) flowing into the sealed cavity, the pressure is higher than the pressure of the medium in the reactor, thereby preventing the medium from leaking. This structure in the case of a large swing of the stirring shaft still guarantees a good seal, and is suitable for glass-lined and various corrosion-resistant stirring shaft seals.
