ZNQ series submersible slurry pump Product Details: ZNQ submersible sand pumps, mortar pumps, pumping sand pump, sand pump iron, ore pump motor and pump coaxial sneak into media work of hydraulic machinery, the pump flow components using high alloy wear-resistant materials, has good wear resistance, over-flow channel, suitable for containing sediment transport, pulp, coal slurry, sand and other media larger solid particles. This series of products designed to absorb foreign advanced technology manufacturing , in addition to increasing the main impeller pumps outside a mixing impeller bottom, can spray deposition of sludge hit into turbulence, so that the pump to achieve a high concentration of transport in case of the absence of auxiliary devices. Unique sealing device can effectively balance the oil inside and outside pressure, the maximum protection of the mechanical seal reliability, using a variety of protective measures motor overheating protection, water protection, detection, capable in harsh working conditions of long-term safe operation. Suitable for extracting building yarn, silt, silt, tailings slurry, ore, iron sands, rivers, lakes, reservoirs, ports and other pumping sand dredging project, but also for mining iron and steel plants, power plants, iron plants, oil and other Grit companies settling ponds cleanup, sewage treatment plants and other precipitates. Features: 1. Machine for dry-type pump, motor with oil chamber sealed manner, equipped with a mechanical seal, can effectively prevent high-pressure water and contaminants from entering the motor cavity. 2. In addition to the main impeller, there are stirring impeller, can sink to the bottom of the sludge stirred into turbulence after extracted. 3. impellers and mixing impeller flow components using high hardness high chromium cast steel, wear, corrosion, sewage capacity, through a larger solid particles. 4. Motor submerged, without limitation suction, suction residue rate, dredging more thoroughly. 5. simplify overall device, and not equipped with a stirring device or auxiliary injection device, easy to operate, with a total investment unit is reduced. 6. stirring impeller directly deposited close to the surface, by controlling the concentration of dive depth. In the case of major media than by the installation of assistive devices, increasing media concentration conditions 1. Power is 50Hz / 380V / 660V three-phase AC power distribution transformer capacity is 2-3 times the motor rated capacity. 2. Medium temperature should not exceed 60 ℃, excluding flammable gas. 3. Medium concentration of solid particles of maximum weight: 45% ash, slag was 60%. 4. Unit diving depth: less than 20 m, the minimum diving depth of submerged motor prevail. 5. Crew working in the media for the vertical position, the upper suspension positioning. Scope: 1. draw rivers, lakes, sea and other underwater sand 2. draw underwater silt rivers, lakes, sea, reservoirs, ponds, power plants, etc. and sand. 3. draw all kinds of stone processing plant powder slurry. 4. tailings transport, a variety of mining tailings, slurry, pulp, coal slurry, slag, slag processing. 5. draw a variety of water slurry job processing various solid slurry items. 6. draw caisson wells in the mud. 7. sedimentation tanks, hydropower stations, reservoirs, rivers, plants, caisson, mine, fish pond sediment cleanup. 8. draw a variety of power plant fly ash, coal. 9. draw all kinds of diamond sand, quartz sand, slag, slag solid particles. 10. sediment transport, pulp, coal slurry, sand and other media containing large solid particles. 11. The gold sand, pumping iron ore.
