The slurry sand pump is one of the important dredging equipment, and it is also called sand pump, dredge pump, slurry pump, electric submersible sand pump, hydraulic submersible sand pump, on board dredge pump, ladder dredge pump, booster sand pump. China Do Pump provides dredging pump solutions, including dredge pump on sale, how to select a slurry sand pump, how a sand pump works, how to maintain a dredge pump etc.
It is important to learn the selection of slurry sand pumps, to master the relevant performance of slurry sand pumps, and to understand the solutions to common problems with slurry sand pumps.
Five tips of slurry sand pump selection - dredge pump for sale
1. There are many types of centrifugal slurry sand pumps. Different types of pumps should be selected according to the nature of the slurry. For example, an L-type pump can be used to transport high-concentration and low-abrasive slurry; a ZGB-type pump can be used to transport abrasive or corrosive slurry; an SP-type pump should be used to transport abrasive slurry containing solid particles into the tank or in the pit.
2. After the slurry sand pump type is determined, the head and flow rate are the basis for selecting the pump size and whether to connect in series. When conveying high-concentration and strong abrasive slurry, the maximum number of revolutions of the pump is generally not selected, and the number of revolutions is about 3/4nmax. If the flow rate is suitable and the lift is not reached, multiple pumps can be used in series.
3. The slurry sand pump should ensure good running stability and safe and reliable operation. Therefore, the selected pump should select the performance corresponding to a short curve after a certain point on a certain flow and head curve. If the flow rate changes greatly during use and the head or pressure changes are small, the steep drop performance curve should be selected. If the head or head change is required to be large and the flow rate change is small, the steep drop performance curve should be selected.
4. The shaft seal type selection slurry sand pump mainly has the form of packing seal, auxiliary impeller seal and mechanical seal. The auxiliary impeller seal is generally used under the reverse irrigation work. The high pipe 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. . Packing seal needs to add shaft sealing water, and ensure sufficient water pressure and water volume. The shaft seal water pressure is equal to the pump outlet pressure plus 35Kpa. The mechanical seal needs to be sealed with shaft seal, good sealing and no leakage.
5.Transmission mode The transmission mode of the slurry sand pump is V-type V-belt drive, flexible coupling drive, gear reducer drive, hydraulic couple drive, variable frequency drive, and thyristor speed control. Among them, the flexible coupling and the V-shaped V-belt are cheap, easy to assemble and disassemble, and should be given priority. But the V-shaped V-belt will increase power consumption by 5%.
