GB/T 25152-2010Specification for liquid-liquid hydrocyclone separators (English PDF)

1 Scope

This standard specifies the liquid - liquid separation cyclone (hereinafter referred to as the cyclone) classification and naming requirements, inspection rules, marking, wide shipping

And packaging.

This standard applies to liquid - liquid heterogeneous two-phase system of separation cyclone. Droplets of dispersed phase into the continuous phase is present in a state dispersed

With not more than 60000mg/L, the dispersed phase volume average particle diameter of not less than 5µm, continuous phase viscosity at the operating temperature of not more than

0.005N · s/m2, the density of the continuous phase and the dispersed phase is not less than the difference between 0.05g/cm3.
