According to the Specific Working Conditions Choose Slurry Pump

According to the specific working conditions, the components of the pump are finely adjusted.

Selection of material of overflow parts: There are many materials that can be selected for the overflow parts of the slurry pump, which should be determined according to the characteristics of the house (particle composition, particle size, shape, hardness, concentration) and chemical (acid, alkali, oil) of the slurry conveyor.

Selection of shaft seal type: The slurry pump mainly has packing seal, auxiliary impeller power seal and mechanical seal and other shaft seal forms. The secondary impeller seal is generally used under the backfill work, and the executive pressure should be less than 10% of the pump outlet pressure, this shaft seal type does not add shaft seal water, but the use of the auxiliary impeller seal reduces the power consumption, generally about 5% of the rated power. The packing seal needs to be sealed with shaft water, and ensure sufficient water pressure and water, and the shaft seal water pressure is equal to the pump outlet pressure plus 3.5 meters head. The mechanical seal needs to be sealed with shaft water, with good sealing and no leakage.

Transmission mode: The transmission mode of slurry pump includes V-shaped V-belt drive, elastic coupling drive, gear reducer drive, hydraulic coupling drive, variable frequency drive device, and thyristor speed regulation. Among them, elastic couplings and V-shaped V-belts are cheap and easy to disassemble and assemble, so they should be given priority. But the V-V-belt will increase power consumption by 5%.
