SW/SWS-PRO/SW Submersible Sewage pump

Introduction

Model screening:after performance optimization, double-channel impeller isadoptedwith two or three reasonablyarranged mechanical seals,which ensures the lubrication and cooling of mechanical seals, the smooth operation withoutblocking and good flow capacity.

Improvement of mechanical seals:seriesmechanical seal isadopted,withmore reliable shaft seal and longer service life.

Structural optimization: the structural design ensures theairtightness of mechanical seals,smooth operation, vibration resistance,drop resistance,and higher reliability.The optimized sewage pump is more portable, practical, corrosion-resistantand wear-resistant. The submersible motor is featured with IPX8 protection level,good cooling effectand temperature rise lower than ordinary motor, which ensure the better durability. Based on the F-level insulation,the motor has longer service life.

The motor is equipped with a variety of protection devices,which is convenient for users'choice at the time of optimization.

MainApplication

It isapplicabletodischarge thewastewater,rainwater and sewage containing solid particles and long fibers in buildings,hospitals,residential areas,municipal engineering,road traffic and their construction, engineering sewage discharge,small-scale sewage treatment and other occasions.

Pump Body& Impeller

Bothpumpbodyand impellerarecarefullyselected, which ensures the good passage capacity of flow channel,highefficiency,flat powercurveand notease to overload.The impeller is featured withaccurate balance,small vibrationand stable rotation.

Motor

Thespeciallydesigned submersiblemotor,featured with IPX8 protection level and F-level insulation, can tolerate the high temperature rise.Under the normal temperature rise condition, the motor insulation life is extended,wile the submersible cooling effect is good and the actual temperature rise is low, thus ensuring the longer insulation life of motor.

Motor Cooling

Theheatofmotordissipates through the casing.As longas half of the motor stator casing is soaked by the medium, the motor can operate reliably and safely. The more it is soaked,the better the cooling effect of the motor.

Shaft Seal

The shaft seal of motor is realized with two or three series mechanical seals,which form multiple reliable sealing defense lines.One of the seals is in the medium of pump.The sealing surface is compressed more tightly with the increase of medium pressure, thus effectively preventing water from entering the oil chamber; the other two sealsare in theoil chamber, which can prevent oil from entering the motor. If the first seal is failed, the other two can still prevent oil and water from entering the motor.Besides, the bellows-type mechanical seals cooperate with the innovative structural cavity to further improve the reliability of shaft seal greatly. Under normal use, the non-failure operation time is more than 9.oo0 hou

Oil Chamber

Theoil chamberis filledwith propermachineoiland installed with two mechanical seals. It is the first barrierto prevent the medium from entering themotor through the pump shaft.If the first seal is failed, the buffer medium in oil chamber can not directly enter the motor. Meanwhile,the friction surfaces of the two independent mechanical sealsare lubricated and cooled to make the mechanical seals work more reliable,which canalso takeaway the heat of lower bearing and some heat of the motor.

Bearing

The lower bearing forms the reliable support of motor pump shaft. According to radial and axial forces and pulsating load generated during the operation of sewage pump,the lowerbearingcan be composed of two or tree different types of beraing,thus ensuring the stable operation and long service life of unit.

CableandCableSeal

1）The cable is sewage-resistant flexible cable with rubbersheath.The cable coresection is designed for long-term and reliable operationat 4oP ambient temperature and motor full-load power.When the sewage pump works,if the motor runs at non-full load power or under the ambient temperature lower than 40P,the longer service life will be ensured.

2)There issealcompressedbetweenthecable rubber sheath and the motor gland, so as to prevent the medium from penetrating into the inner cavity of motor from the interface between cable and motor gland. 3) There is rubber vulcanization between the cable sheath and the cable core.Once the rubber sheath isscratched, it canstill effectively prevent the medium fromentering the motor through the sheath.

MotorShell

The frame,bearing seat and cover compose the motor shell.The connection place of all components is provided with the reliable static seal. Besides,each motorhas beenchecked through thestrict hydrostatic test,so as to ensure the good water tightness.

Safety Protection in Motor Pump

(operated by the special electricallycontrolled phase)

1) Oil-water probe: installed in the oil chamber to checkthe leakageof the firstmechanicalseal (in the medium),which will send the alarm signal when the medium leaks into theoilchamberand reachesa certain proportion.

2) Inlet probe: installed in the motor chamber to check the leakage of the second mechanical seal, which will send the alarm signal and stop the pump when the oil (oil-water mixture) enters the motor. 3) Thermo-sensitive element: installed in the motor stator winding,which will send the alarm signal and stop the pump when the motor is overloaded for long time and the temperature of motor winding (or the heating of the motor winding caused by other reasons) reachesacertain value.

The cable is covered witha rubber sheath.The cable coresectionisdesignedaccordingly
