Medium is generally not more than 40% of the solid content, such as solid as the powder particles content up to 60% or higher,Water coal liquid etc.

 

4、According to the pump speed range of different media

If the medium containing abrasive materials,Must according to its degree of abrasion,According to table 5 reduce the operating speed of the pump,In order to ensure the pump have enough life。

5、According to the medium containing abrasive material, pump the allowed maximum running speed.

1、Table column flow Qmax syste mp=0,The theoretical value of corresponding rotational speed。

     2、All kinds of medium containing abrasive materials, for example:

     A、No abrasive medium:Fresh water, oil, pulp, glycerin, blood, soap and water, etc;

     B、Light abrasive medium:Soft mud and water cut more than 95% of the sludge, such as activated sludge water, refined sugar liquid, livestock excrement, industrial waste, etc;

     C、Medium abrasive medium:Mud containing solid material, water cut more than 85% of the mud, such as coating, molasses, grind cutting fluid, gypsum slurry, etc;

     D、Serious abrasion medium:Coal water slurry, slurry containing abrasive material, more than 50% of the moisture content of sludge, such as grinding fluid, hot springs, mud, PVC paste, clay, dehydration agent etc.

     D、Medium viscosity is also selected pump needs to be a factor, the operation of the pump speed as the medium viscosity decreases, if viscosity reaches more than 150000 mpa, the general structure of the pump can't inhale, then you must add feeder and other special design.
