Introduction of sand pump 1, Introduction: Sand pump is a centrifugal mud pump for conveying sand, slag and other suspensions. Impeller mostly open. Pump lining generally divided into two kinds, wear-resistant metal box wear-resistant rubber. In addition, high pressure water is injected into the sliding part of the pump shaft to prevent mud from entering the sliding part. This pump can be used for the transportation of coarse solids containing liquids with a mesh size above 48 meshes. 2, type: sand pump is only a specific application of centrifugal pump named after the pump. In essence sand pump is just a general term. Generally used in mining, coal, metallurgy, chemical industry, environmental protection and other industries. Multi-stage pumps in the general sense of the sand pump is more used in environmental protection, dredging, river dredging and other industries more. This series of sand pumps mainly ES or G series more. In addition, there are many types of sand pumps called SB sand pumps in the oil field and PS sand pump series in the mining industry. Diaphragm Pump This article describes the sand pump in the usual sense of the ES or G series of dredging, sand pumps used in the environmental protection industry. 3, Structure: ES Series sand pumps are horizontal, single-pump shell centrifugal pump. Using a special clamp clamp the pump body and pump cover, pump outlet direction can be 360 ​​degrees in any position, easy to install. Self-priming pump sand pump bearing assembly cylindrical structure, easy to adjust the gap between the impeller and the pump body, the overall removal can be repaired. Bearing grease lubrication. Shaft seal in the form of packing seal, impeller seal, mechanical seal. Sand pump flow channel wide cavitation performance, high efficiency, abrasion resistance. Gear pump drive mainly V-belt drive, flexible coupling drive, gear reducer drive, hydraulic coupling drive, frequency drive, SCR speed and so on. Flow components using high hardness wear-resistant alloy cast iron. Using a variety of speed and a variety of variants, making the pump running in the best conditions Drum pump long life, high operating efficiency, to meet the many types of poor transport conditions. 4, Application: This type of sand pump is mainly used for continuous conveying of highly abrasive materials that can not be transported by the slurry pump because the particles are too large. Dosing pumps for dredging, sand suction gravel, dredging the river, mining and metal smelting slag delivery.
