How to choose the right tailings pump?
How to choose tailings pump, in addition to the reference product's own model, operating environment differences, but also pay attention to the issue of energy efficient. Today, Xiaobian teach you how to choose the right tailings pump to achieve the purpose you want? How to choose the right tailings pump? 1, according to different flow selection tailings pond paste pump, first of all from the flow point of view, the slag Pulp pump flow of up to 5,000 cubic meters per hour, water pump 1000 meters per hour or less, the plunger pump 300 meters per hour below, tailings pond paste pump up to 1500 cubic meters per hour. The size of the delivery flow is a key factor in the selection of the pump type, but the most important factor is the fluctuating range of delivery lift and head lift and the environmental conditions in which paste and slurry concentrations are used. The total delivery flow of 60 m 3 / h or less, the slurry pump, tailings pond paste pump, plunger pump can be delivered to a single station. Flow 200 ~ 1000 m 3 / h. Slurry pump, tailings pool paste pump can also be delivered to a single unit, but the plunger pump must be more than one parallel. Flow of more than 1000 In / h, tailings pool paste pump must also be more than one parallel. Slurry pipelines, the use of parallel multi-pump is often, there are certain technical problems. Just running too much management is not convenient, covers an area larger. Therefore, the delivery of a total flow of more than 2000 m 3 / h, rarely consider the use of piston pump. More than 3000 m3 / h flow is the choice of high-pressure oil diaphragm pump or tailings pool paste pump, mainly to see the head. Less than 700m head. Tailings pond paste delivery pump. More than 800m head. Also depends on the series of several high-pressure diaphragm pump, or a few parallel pond tailings slurry pump. The current flow rate of 1500m3 / h or less and lift more than 60m, and the transmission distance, the undulating topography of the general selection of tailings pond paste pump is the most appropriate environmental conditions. For example, a copper mine, the flow at 2800 m / h, head at 620m. If you use the slurry pump, you need eight in series, water pump isolation needs 5 parallel, and the selection of plunger pump needs l0 parallel, and the tailings pond paste pump only 4 in series to meet, because the tailings slurry After highly concentrated up to 60%. After considering the standby pump, the number of slurry pumps needs 16 units. Need 8 water isolation pumps, plunger pumps need 15 sets. In this case, from a one-time investment, management convenience, regular maintenance costs and operating costs, etc., are selected tailings pond paste pump is superior, Moreover, tailing pond paste slurry delivery pump regardless of the series Or parallel can be, in series is to increase the head, parallel is to increase traffic. 2. Select the tailings pump according to different lift From the head of view, the slurry pump is generally below 100m; the water pump is below 640m; tailings pond paste pump at 720m; plunger pump below 2000m; mine Sediment legislation pump at 500 meters below. General low lift stable below 60m, choose the slurry pump better. Because the slurry pump structure is simple, easy to maintain. Less investment, less than 60m head, generally two or three series can be, so that regular maintenance costs are not higher than the piston pump, piston pump. When the lift is stable more than 100m and less than 700m, in this stable range of head to select the tailings pond paste pump more appropriate. This lift range, tailings pool paste pump delivery pump station can be to avoid the slurry pump multistage pumping station .One-time investment, and multistage in series slurry pump investment. The first pump station management convenience, regular maintenance costs are slightly lower. Tailings pond paste pump efficiency is also higher than the slurry pump. In the 500m ~ 1000m choice of stable lift piston pump is not too much advantage. Although more efficient, but one-time investment is too high, the regular maintenance costs are not lower than the water pump. When the head of more than 400m, especially over 640m, the choice of high-pressure diaphragm pump, it is best to choose mine sand-setting pump more appropriate. This high-pressure diaphragm pump expensive, not as good as mining sand pump vertical parallel instead, because a mine drainage legislation pumping pump station management convenience, recurring maintenance costs are relatively lower. From a variety of slurry pump stand-alone point of view: the slurry pump head low flow larger; plunger pump flow is higher head lift; mine sand sedimentation pump flow and head are more moderate; tailings pool paste pump synthesis The advantages and disadvantages of all pumps, large flow, high concentration, moderate lift, low energy consumption and so on.
