QW series submersible sewage pump

times：

Summary.
QW series submersible sewage pump is the digestion, absorption of foreign advanced technology products based on the successful development, with high efficiency, winding prevention, no clogging, automatic coupling, high reliability and automatic control etc., in the discharge of solid particles and long fiber waste, has a unique function. QW series submersible sewage pump is mainly used in municipal engineering, industrial, hospitals, construction, hotels, restaurants and other industries. For the delivery of solid and all kinds of long fiber of silt, waste water, city domestic sewage ( including corrosive, erosive medium. ).
QW series submersible sewage pump has the advantages of small volume, compact structure, high efficiency, can according to user requirements for the water level automatic control, and equipped with automatic protection device and a control cabinet, double track automatic installation system. This series of pump discharge nozzle diameter of 50 ~ 600mm, the flow of 10~7000m3/h, head of 5 ~ 60m, power is 1.5~315KW, the solid particles with a diameter of 20~145mm.
Structure characteristics:
QW series submersible sewage pump has the advantages of compact structure, and set the status display, protection device, the pump running safety, reliable.
* unique cable seal design, eliminates the hidden trouble of water leakage cable.
* the stator adopts the insulation class F, equipped with a thermal protection element.
* 18.5KW above pump with external circulation cooling water automatically, ensure electric pump in the lowest level of state of security operation.
* the motor cavity bottom with float switch, the motor side mechanical seal monitoring.
* in the pump and motor oil chamber arranged at the upper end of the oil-water probe on mechanical seal, pump side monitoring, once the water leakage, the control system will alarm and protection.
* the bellows type double mechanical seals, sealing materials for tungsten carbide, silicon carbide and tungsten carbide, prevents water from entering the motor, guarantee the safe and reliable operation of motor.
* vice impeller for balanced mechanical seal external pressure, prevents water from entering the oil chamber, thereby prolonging the service life of electric pump.
* impeller design unique, large flow can pass through the long fiber and dirt, blocking resistance, winding prevention, over-current capability.
* impeller and volute casing is arranged between the lower end of a replaceable wear sleeve, keep the pump running at optimum efficiency.Use characteristics:
In 1, the motor rated voltage 380V ( 660V ), the frequency of 50HZ three-phase AC power supply.
In 2, the conveying medium temperature does not exceed 40oC.
3, conveying the liquid medium pH value 4-10.
4, transport medium solid phase volume ratio below 2%.
In 5, the conveying medium density is less than 1.2*103Kg/m3
Impeller design features:
In order to ensure the smoothly through the dirt, must increase the impeller flow surface width, can be used for large pump, double blade, three-blade; for a small pump, uses the single ( double ) channel form, it is similar to a cross section of the pipe the same size, and very good flow characteristics. Avoid water flow in low speed situation likely caused by a blockage, winding. The unique design of the impeller, with reasonable volute chamber, so that sewage of paper, textile, garbage bags and other materials can be freely through. After impeller dynamic and static balance, so that the pump in the no-load trial running and loading process without generating vibration.
