3. Features of QJB-W sludge return pump

1. Specially designed according to micro-lift and large flow, high efficiency.

2. Resistant to clogging and entanglement, use reliable

3. Adopt the latest sealing materials, can safely operate continuously for more than 10,000 hours

4. Compact structure, convenient installation and maintenance.

5. The host adopts a stamping and forming structure, which is small in size, high in precision, corrosion-resistant and noise-free.

6. Built-in leakage and motor overload protection (alarm) devices to ensure product safety and reliability.

4.QJB-W type sludge return pump composition structure

Specially designed equipment components and equipment spare parts enable the sludge return pump to achieve better performance.

1. Cable: The cable adopts a special watertight cable.

2. Junction box: The junction box is fully enclosed and isolated from the surrounding liquid and the 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 tested for dynamic balance.

5. Sealing: The static seal is an O-ring seal. The shaft seal is a mechanical seal, which isolates the oil chamber from the surrounding medium.

6. Bearings: Imported bearings are used, and the designed service life can reach more than 100,000 hours.

7. Oil chamber: oil is used to lubricate and cool the friction pair of the mechanical seal and isolate the penetrating liquid.

8. Impeller: The impeller has three blades. The blades are wide and thin. The surface is smooth and swept back. It runs efficiently and without hindrance, and has a self-cleaning function.

9. Imported cone tube: The purpose of the imported cone tube is to form a better flow state.

10. Discharge joint: The discharge joint is used to fix the inlet cone pipe on the outlet pipe.

11. Guiding device: The guiding device is composed of two tubes (catheters) and the upper catheter clamp.

5. Installation of QJB-W sludge return pump

1. Correct installation and use is the basic guarantee for the long-term and normal operation of the pump.

2. The sludge return pump adopts an automatic coupling installation system, which can quickly upgrade the equipment for inspection and maintenance without any mechanical disassembly, and the installation is convenient and quick.

3. In addition to the pre-embedded pipe through the wall, the guide rod and lifting frame are all connected with the tank body with steel expansion bolts, and no pre-embedded parts are required.

4. The embedded parts and the shutter are purchased and installed by the user, and the user should pay attention to it when ordering.

6.Use condition of the QJB-W sludge return pump

1.Highest medium temperature: <= 40 °C

2.Medium pH value: 6~9

3.Submersion depth: <=10m
