3、 Characteristics of RJC series long shaft deep well pumps for hot and cold water

1. Advanced hydraulic models and structural designs are selected, and various new processes such as Ashland process for core making and epoxy coating for blade flow channels are adopted. The material selection is reasonable, the product performance is excellent, and the service life is long.

2. The water pump has high efficiency, 2-8% higher than domestic J, JD, and JC water pumps. The efficiency curve is gentle, the high-efficiency area is wide, the working range is increased by 10-20%, and the energy-saving effect is significant.

3. Adopting a sand throwing pump device, the labyrinth structure prevents sand particles from entering the bearing.

4. The impeller shaft and motor shaft are supported by copper bearings, and the radial runout of the shaft is controlled within 0.13mm. The pump runs smoothly with low noise.

5. The pump seat has a beautiful design and a large window, making it easy to maintain and replace the packing.

6. Compared with domestic pumps with the same flow rate, the outer diameter of the working components is about 1 inch smaller, which can significantly save users' well completion costs and facilitate the renovation of pumps suitable for old wells.

7. The special structural design of the closed transmission system that can be lubricated with oil, as well as the option to use ductile iron, ASTM304、 Various grades of stainless steel materials such as 316 and 416 are used to meet users' special operating conditions and technical requirements.

4、 Application scope of RJC series long shaft deep well pump for hot and cold water

The RJC series long shaft deep well pumps for hot and cold water are widely used in water plants, hydropower stations (for maintenance, leakage pumps, etc.), thermal power plants (for industrial, domestic, fire pumps, etc.), steel plants (for iron pit pumps, etc.), agricultural irrigation, fire protection, municipal and other industries.

5、 Internal structure of RJC series long shaft deep well pump for hot and cold water

1. Motor: Hollow shaft motor for deep well pumps (YLB type), or solid shaft ordinary vertical motor.

2. Adjust the nut: Adjust the axial displacement of the impeller.

3. Pump seat: capable of withstanding heavy loads and facilitating the installation of packing boxes.

4. Pre lubrication plug: Before starting, inject clean water through this area to lubricate the internal bearings of the water pump.

5. Upper short pipe (short pipe B): connected by flange, the upper flange of the short pipe is connected to the pump seat, and the lower flange is connected to the flange of the lifting pipe.

6. Wheel shaft: 2Cr13 stainless steel or 45 # high-quality carbon steel (surface chrome plated).

7. Mid shell: Smooth flow channel reduces frictional resistance and improves efficiency. The materials are: HT200, QT450, 2Cr13, 304, 316, etc.

8. Impeller: Designed in conjunction with the middle shell, it is efficient, has a wide operating range, and undergoes precise balancing to ensure smooth operation. Material: HT200, silicon brass QT450、2Cr13、 304, 316, etc.

9. Medium shell bearings: copper bearings, wear-resistant rubber bearings, or imported polymer bearings. Reliable work and long lifespan.

10. Cone sleeve: securely fix the impeller onto the impeller shaft.

11. Lower shell bearing: Copper bearing, grease filled, long-term trouble free operation.

12. Lower shell: Guide the liquid in the water filter evenly towards the impeller with minimal loss. The materials are: HT200, QT450, 2Cr13, 304, 316, etc.

13. Water filter mesh: The length of the water filter mesh should be appropriate to achieve good condition and prevent large particles from entering the water pump.

14. Drive shaft: High strength carbon steel, chrome plated on the surface of the bearing position. Stainless steel material can be provided as needed.

15. Lifting pipe: Lifting pipes can be installed using threaded connections or flange connections.
