Slqgl Submersible Crossflow Pump

Model NO.: SLQGL Working Pressure: Low Pressure Pump Position of Pump Shaft: Horizontal Pump Mounting Height: Since Irrigation Centrifugal Pumps Usage: Pumps Head: Less Than 5.5m Specification: CE; ISO9001 HS Code: 8413709990 Impeller Number: Single-Stage Pump Influent Type of Impeller: Single Suction Pump Pump Casing Combined: Horizontal Split Pumps Impeller: Closed Capacity: Less Than 108000m3/H Trademark: Sanlian/Kubota Origin: Anhui, Ma′anshan Description
SLQGL series submersible crossflow pump is combined with the technology of submersible motor and crossflow pump,which keeps the advantages of crossflow pump and also uses the technology of submersible motor,overcoming the problems of cooling,heat dissipation,packing of traditional crossflow pump.It is much more excellent than traditional machine.
The pump is applicable for condition that is large capacity and low head.It is used to transport clean water without solid particles and other liquids with physical and chemical properties similar to clean water.The temperature of transported liquid can not exceed 40ºC.

Application Area
The pump can be used in agricultural irrigation,industry&mining,dock,urban construction and water-supply&drainage of power plant,and it is especially applicable in urban flood control project,sewage project and drainage project,(Special requirements can be designed),and it is widely used.

Performance Range
Diameter:≤3400mm
Capacity:≤ 108000m3/h
Head:≤5.5m

Structural Characteristics
1,  Impeller
Impeller is based on the most advanced hydraulic model with good ,steady,mature performance.Much lower nD value is chosen with better anti-cavitation to make sure stead operation.
2,  Shaft seal
Two sets of separate mechanical seals are used to ensure the safety and reliability of sealing.
3,  Monitoring device
Submersible crossflow pump has several protection devices which lead the leading wire to electric control cabinet,and the protection devices are:stator temperature protection,protection of bearing temperature rise ,protection of motor water inlet,protection of oil cavity temperature rise .
4,Pump/motor shaft
Pump and motor are concentric with compact structure,and the shaft extension is shortened as much as possible,and the rigidity is improved.Deflection is controlled within the allowable range based on the design,and the vibration is lower when operating.Service life of sealing and bearing is much longer.
5,  Flow passage
CFD and experimental method are combined to confirm the flow line shape to ensure high efficiency when operating.
6,Cooling
Motor casing passes the heat into the surrounding medium,and the heat is taken away by the surrounding water.High power high voltage motor uses inner air passage heat dissipation technology,which makes three-phase winding temperature rise lower with an even temperature field distribution.
7,Motor
High performance squirrel cage induction motor is specially designed for Submersible Pump according to GB/T755 standard.Thermal classification is F,and 380V,660V,6KV,10KV etc. voltage classes are used.Two VPI insulation processes are used to ensure the reliable insulation of motor.
8,Bearing
As for horizontal structure,large common structure finite element analysis software is used to analyze rotating components dynamically,researching its deflection,vibration,inner stress,support counter-force,characteristic frequency.And the design of structure,bearing arrangement,bearing choosing are all based on this foundation.Rolling bearing is used to bear all the axial and radial loading,totally separated from the transported medium.
