High head submersible pump

High Head Submersible Pump Brief Introduction: QJ40-500 Q: submersible J: for well use 40: flow rate (m3/hr) 500: head (m) QJ series high head submersible pump is a lifting equipment with motor and pump integrated directly. The motor is water-filling type and the pump is multistage vertical structure. It is not only applied to deep well water lifting, mining drainage, but also to water lifting projects, such as river , ditch, reservoir. Meanwhile it is used in mountainous area water supply, urban water supply and factory drainage, railway, construction site, etc. The series of our products have many advantages, such as high head with single stage, advanced technology, low noise, long service life, high efficiency, simple structure, easy installation, small outer diameter, exquisite outline etc. Characters: QJ series high head submersible pump is a complete set of lifting deep well water , composing of QJ series pump and YQS series motor. 1. Mechanical motor integration, operation in water, Safety and reliability2. No special requirements for well pipe, as long as pipes can bear the pressure.3. Easy installation and maintenance, small size4. Simple structure, material saving5. Flow rate:10-40m3/h6. Head: 300-1550m Application conditions: Rated voltage: three-phase alternating current 300v/660v(±5%) , Frequency: 50HzSolid content (mass ratio): ≤0.01%PH value: 6.5-8.5Pumping medium temperature range: +5°C--+105°CThe inlet must be submerged into dynamic water no less than 1m and the submerged depth no more than 70m, the lower distance to the bottom of the well is no less than 1m.Straight well and smooth well wall are required. Well pipe shall not be staggered.Structure characters: QJ series high head submersible pump includes 3-phase asynchronous motor and pump. The motor is connected to the pump. Shaft seal device is fixed at the front part of the motor shaft, which effectively prevent coolant exchanging with the delivered medium in the motor and ensure operation safe and reliable .Submersible pump is single suction vertical centrifugal pump. Motor is water-filling, vertical. And motor connects with pump by coupling.Motor winding is Nylon sheathed polyethylene water resistant electromagnetic wire. Motor cavity should be filled with clean water.Motor shaft is lubricated by water. There is a thrust bearing withstanding upper and lower axial force at the end of motor. The thrust bearing adopts copper-nickel fan-shaped alloying block, grinding against imported Fieldbus segment .High head submersible pump is equipped with axial loader, the head increased to 1550m.Notes QJ series high head submersible pump should be filled with clean water before operation. Please drain water away from motor avoiding frost crack without use in winter.Inspecting insulation resistance regularly, R≥0.5MΩGuarantee period is one year. Friendly reminder: For the customers’ convenience and our products’ quality, all the related products are manufactured by ourselves. The products detailed information are as follows: a All kinds of lifting pipes including high-frequency welded pipes (dia.25mm-500mm); Connection type: flange connection. They are made accurately by machine tools. b Pipe clamp: the length is 50mm-500mm (we can produce the other different spans according to your requirements). c Wellhead devices: return flow wellhead instruments (applied to ground source heat pump), general pump seat (we have innovated and designed this kind of pump seat by replacing the original iron castings with steel plate welding; the cable lead-in hole has also been improved by substituting the U hole for middle lead-in hole, thus making more convenient for the customers.) d Desander: avoiding blocking and polluting by sand in water. And it contributes to long service life. e Related products: submersible cable, starting cabinet, frequency conversion cabinet, transformer, electric generating set, etc. f According to the conditions on the spot, we also supply the design proposals about pipe network, tank and installation.
