Dehumidifier principles of sealing selection:
Selection of main parameters: the sealing chamber pressure (MPa), flow-chemical process pump mechanical seal temperature (℃), speed (m/s), fluid KSB pumps mechanical seal characteristics and effective space of installation seal.
1. depending on the temperature and fluid properties, determining friction and auxiliary materials, and proper selection of lubrication, cleaning, insulation, mechanical seal cooling loop protection system;
2. According to the seal chamber pressure to determine seal structure with balanced or unbalanced, such as single or double face;
3. According to the effective space of installation seals determined using spring or spring or wave spring, Interior or exterior.
4. depending on the working speed, using Rotary or static, hydrodynamic or non-contact type.
