Product Description

Scope of application

QJB-W sludge reflux pump is a new product developed based on the production technology of submersible mixer. It is a special equipment for mixed liquid reflux and denitrification in the secondary sewage treatment plant, and can also be used for pumping purified water during ground drainage; Irrigation and control waterway systems; Micro-head, high-flow locations where recirculation or mud pumping circuits are required during wastewater treatment.
 

Working Conditions:

1. During continuous operation, the medium temperature shall not be higher than 40ºC;
2. PH value of medium is 6-9.
3. Maximum depth of submergenceM long.

 

Introduction to structure

Specially designed plant components and equipment spare parts allow optimum performance of the sludge return pump.
1. Cable: special watertight cable;
2. Junction box: the junction box is fully enclosed and isolated from surrounding liquid and stator box;
3. Motor: 50Hz squirrel-cage 3-phase submersible asynchronous motor, class F insulation, protection class IP68. The motor is cooled by the surrounding medium;
4. Shaft: the shaft of the motor is made of stainless steel, and the rotor is subject to dynamic balance test;
5. Seal: static seal is O-shaped seal ring. The shaft seal is a mechanical seal to separate the oil chamber from the surrounding medium;
6. Bearing: imported bearing with design service life of over 100000 hours;
7. Oil chamber: oil is used to lubricate and cool the friction pair of mechanical seal, and to isolate the penetrating liquid;
8. Impeller: The impeller has three blades, wide and thin, smooth and backward facing surface, efficient, unblocked operation and self-cleaning function;
9. Inlet taper pipe: the purpose of inlet taper pipe is to form the best flow state;
10. Discharge joint: the discharge joint is used to fix the inlet taper pipe on the outlet pipe;
11. Guide: The guide consists of two tubes (catheter) and upper catheter clamp.
 

Product features

1. Specially designed for small head and large flow, with high efficiency;
2. Anti-clogging, winding and reliable use;
3. With the latest sealing materials, it can operate safely and continuously for more than 10000 hours;
4. Compact structure, easy installation and maintenance;
5. The main machine adopts stamping forming structure, which is small in size, high in precision, corrosion resistant and noiseless;
6. Leakage and motor overload protection (alarm) devices are provided to ensure the safety and reliability of the product.
