How can the water pump mechanical seal design

Mechanical seal is an important parts, water pump is a submersible pump leakage prevention, energy saving as well as the important basis of controlling pollution of the environment, design the water pump mechanical seal or there are a number of requirements.

1. The first design the main is to consider the mechanical seal mechanical seal of the working environment.

2. The nature of the medium to be sealed: gas medium; Low boiling point, low saturated vapor pressure of liquid medium; Sealing medium corrosive, solubility; Sealing medium containing impurities, particles; Sealing medium viscosity; Sealing medium of toxic, flammable and explosive;

3. The temperature of the sealed medium, namely the sealed cavity actual temperature: high temperature, normal temperature, low temperature, temperature cross range;

4. The medium pressure, namely the actual pressure seal cavity
