Product Description General InformationQZ 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-pumps ApplicationThis 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 projects Performance Parameters Table ModelCapacity(m3/s)Installation angleHead(m)Pump efficiency (%)Shaft power (kW)Speed(rpm)Impeller outer diameter(mm)700QZ-1251.42-63.4681.6158.917306501.5-43.8581.8869.31.64-24.1382.5380.691.8704.0982.9890.38 1.9824.3483.16101.1 Product 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)1100Outlet diameter of outlet elbow(mm)800Flange 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 HT250,OptionalPackagePump weight(kg)2500Optional accessoriesOptional accessoriesOutlet matching flange, terminal box, electric control cabinet Product FeatureHigh-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 function Structural 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 performance;Independently developed hydraulic model,high efficiency area is wideAdopt metal mould, precision casting4.Cable locking sealing systemThe cable outlet adopts special structure,which eliminates water leakage, electricity leakage,short circuit,and stator coil burnout caused by accidental factors such as artificial pulling,broken cable jacket, and cable aging,which effectively reduces the probability of failure caused by water in the upper part of the whole machine5.BearingsAt the pump end is equipped with a thrust spherical roller bearings(the oil lubrication),withstand the axial thrust of pump,There are one cylindrical roller bearding and one deep groove ball bearing(grease lubrication)equipped with the top and bottom of the motor, withstand the radial force of rotor.The bearing running stable,and the motor shaft will not movement,so the bearing has little heat and no noise during the operation of the pump5.Sealing systemThe product applies a patented structure, the pump end adopts a combined double cartridge mechanical seal,and the motor side also adopts a single end mechanical seal.The structure makes the sealing performance of the pump reliable and running stable.Why Us
