Industrial Electric Non-Clogging Vertical Centrifugal Submersible Sewage Water Pump for Wastewater Drainage

OverviewIt has many obvious advantage such as compact structure,no overload,high efficiency and energy saving,high reliability,high stability,anti-winding,no clogging,automatic coupling,automatic protection and automatic control,it has unique functions in transporting various kinds of sewage or insoluble solid-phase mixed liquids containing solid particles and sediment.The design,manufacturing and quality of this series of products comply with GB/T24674"Waste submersible motor-pumps"standards,CJ/T472"Submersible sewage pump"standards,and its efficiency index reaches GB32031"Minimum allowable values of energy efficiency and energy efficiency grades for waste submersible motor-pumps"standards.ApplicationThis series of products are mainly used to transport various types of sewage,wastewater,rainwater,or other insoluble solid phase mixed liquids containing solid particles, sediment,fiber,and so on. The products are widely used in urban sewage treatment plant drainage system,factory commercial heavily polluted wastewater discharge,residential area sewage drainage,civil air defense system drainage,hospital and hotel sewage drainage,complete auxiliary machinery drainage for hydropower station,auxiliary drainage for water conservancy pump stations,exploration,mining supporting equipment,waterworks water supply equipment, municipal engineering,construction site,subway station drainage and other industries Performance Parameters TableModelCapacity(m³/h)Head(m)Pump efficiency (%)Shaft power (kW)Speed(rpm)400WQ1800-34-280126039721869801800347821423402876235Product AttributeAttributeAttributeAttribute valueMaterialImpellerHT250Pump cover HT250Pump shaft2Cr13Seal ringZG07Cr19Ni10BearingSKFMotor coverHT250VoluteHT250Suction bellHT250Guide rail06Cr19Ni10Sling chain06Cr19Ni10Coupling mounting baseQT500-7Fixed/mobile mounting baseQ235-BCableSpecial cable for submersible pump 10mWorking conditionsMedium temperature (ºC)≤42ºCSolid≤120Medium PH value4~10Medium density≤1200kg/m3Volume ratio of solids phase≤5%Flange grade1.0MPaInstallationInstallation methodCoupling installationInlet and outlet diameter400Direction of rotation MotorNumber of motor phasesthree phaseProtection classIP68Number of motor poles6PInsulation classHMotor Power(kW)280KWRated voltage(V)380Rated current(A)542.4Power factor0.83Motor efficiency(%)94.5Stall torque/rated torque1.8Power cable outer diameter(mm)(3×mm2+1×mm2)44(3×70+1×25)Control cable outer diameter(mm)23PackageWeight(kg)3460OtherMonitoring pointWinding temperature rise protectionStructural feature1.Special submersible motorThe whole series of motors are of H-class insulation,temperature resistance reaching 180ºC,protection level is IP68, low energy consumption,low temperature rise,and high stability,compared with ordinary motors, increase heat resistance by 60 degrees celsius, extend the life, and the wiring chamber is sealed and separated from the stator and rotor of the motor, which brings double insurance.The motor bearing adopts the auxiliary oil tank structure, which increase the bearing service life.2.Electric 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.Impeller,voluteThe products adopt three-dimensional flow theory design, CFD calculation simulation,non-blocking,non-overload design, and are of high efficiency, wide efficient range,low energy consumption, and adopt double-flow channel non-blocking impeller.The passage of the pump body is wide, so the solids are easy to pass, and the fibers are not easy o entangle. The impeller is strictly balanced to minimize vibration and maximize the life of bearings and mechanical seals.4.Cable anti loose 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.Cooling systemThe motor uses four sides to contact with water or air,which greatly improves its heat dissipation capacity. The motor bearding housing is in direct contact with water or air,which enhances the heat dissipation capacity of the bearing and greatly increases the service life of the bearing.According to the water level,cooling-jacket cooling system is provided to ensure that the motor can continue to run when it breaks the surface of water6.Sealing systemThe product adopt patented structure, double sealed chamber structure,three sets of mechanical seal are used in the pump,and a buffer chamber is added.This greatly increases the reliability of the seal and c
