Large Flow Industrial Electric Vertical Submersible Axial Flow Water Pump for Farmland Irrigation

OverviewQZ series submersible axial flow pump is a new generation of submersible axial flow pump products independently developed by our company,it is not only simple in structure,easy to disassemble and assemble,but also has excellent performance as an alternative to traditional axial flow pump.This QZ series of products has a wide spectrum,good hydraulic performance and novel structure.it is characterized by high efficiency,good cavitation performance,easy installation and maintenance,at the same time,combined with the latest information control technology,the intelligent water pump system independently developed can be configured,with automatic monitoring function.The design,manufacture,and quality of this series product meet the standard of GB/T13008 Technical conditions for mixed-flow pump and axial-flow pump,JB/TLarge and medium-sized submersible motor-pumpsApplicationThis series of products can be used for clear water or other liquids with physical and chemical properties close to water whose temperature of conveying medium is no more than 43ºC. They are widely used in municipal engineering, large-scale water conservancy projects, farmland irrigation,industrial conveying water.The thermal power station car-ries circulating water.Shipyard level,urban water supply and drainage and water diversion projectsPerformance Parameters TableModelCapacity(m³/s)Installation angleHead(m)Pump efficiency (%)Shaft power (kW)Speed(rpm)Impeller outer diameter(mm)1200QZ-1253.16-63.4783.19129.34909703.35-43.8783.45152.53.67-24.1484.07177.14.1704.184.51198.44.4124.3684.69222.64.6844.5883.69251Product Attribute AttributesAttributesAttribute valueMaterialMachinery SealImport/DomesticBearingImport/DomesticDiffuserStandard HT250,OptionalConnectorStandard A2-70,OptionalMineshaftStandard Q235-B,OptionalPump caseStandard Q235-B,OptionalImpeller chamberStandard HT250,OptionalWheel hubStandard HT250,OptionalImpeller Standard ZG07Cr19Ni10,OptionalWorking conditions Medium temperature(ºC)≤42ºCRated voltage380V/660V/3KV/6KV/10KVFrequency(Hz)50HzStart methodSoft start or frequency conversionDirection of rotationFrom the drive end,the pump is rotated in clockwiseInstallationStructure typeStandardInstallation methodStandard steel wellbore, optional concrete wellboreWellbore Diameter(mm)1700Outlet diameter of outlet elbow(mm)1400Flange grade0.6MPaMotorControl cableSubmersible pump special cable 10mPower cableSubmersible pump special cable 10mIron coreCast aluminum (low pressure) / copper bar (high pressure)StatorSilicon steel sheet + copperShaftStandard 2Cr13,OptionalJunction BoxStandard HT250,OptionalMotor housingStandard Q235-B,OptionalPackagePump weight(kg)8000Optional accessoriesOptional accessoriesOutlet matching flange, terminal box, electric control cabinetProduct FeaturesHigh-efficiency energy saving: the hydraulic model is designed by 3-D flow theory and calculated by CFD computational simulation,with the best performance in theory. Hydraulic components are made of metal mold,cast precisely guide blade mould is machined by CNC;guide blade shell and suction cone blank are cast by resin sand,solid flow channel is completely in accordance with design drawings,with efficiency higher, and wide high efficiency zoneHigh reliability:the design of the inlet flow channel is reasonable, the inlet water is uniform without vortex, with smooth running, the absolute concentricity o the pump shaft, and the excellent static balance of the rotor parts ensure that the pump has low vibration and low noise when running at high speedAdvanced technology:all parts using metal mold,precision casting,parts quality is reliableLow maintenance: reasonable structure,convenient assembly and disassembly, and simple maintenanceInventory management: reasonable inventory management,short lead time,fast deliveryAutomatic monitoring: Equipped with intelligent water pump system independently developed,with automatic monitoring functionStructural Feature1.Special submersible motorThe whole series of F/H grade insulation,B grade temperature rise assessment, protection grade is IP68;the motor has low energy consumption, low temperature rise, and high stability.It has better heat resistance and longer life than ordinary motors.The wiring cavity is sealed from the stator and rotor of the motor, with double insurance.The motor bearing adopts the auxiliary oil tank structure to increase the service life of the bearing.2.Motor pump protection systemThe motor has a number of built-in warning sensors,including the leakage in the wiring chamber,the motor cavity and the oil chamber, and the temperature rise of the bearding and the motor coil. The motor is equipped with water leakage monitoring,and the oil chamber is equipped with oil mixed water probes.There is comprehensive monitoring of motor operating conditions.3.Hydrodynamic partsThe 3-D flow theory design and CFD computational simulation are adopted,with high efficiency and wide high-efficiency zone, and good cavitation p
