500RJC1000-29 series long shaft deep well pump

500RJC1000-29 series long shaft deep well pump

Brief introduction of long shaft deep well pump

The 500RJC1000-29 series long shaft deep well pump adopts advanced hydraulic model and structural design, adopts Ashland resin process to make core, and epoxy coating on the blade flow path. The pump has high efficiency and no hump in the performance curve. The high-efficiency area is wide. The water pump adopts sand throwing device, and the labyrinth structure prevents sand particles from entering the bearing. The pump runs smoothly and has low noise. The pump seat has a beautiful appearance and a large window, which is convenient for maintenance and replacement of packing.

Application range of long shaft deep well pump

RJC type long shaft deep well pumps are widely used in water plants, hydropower stations (pumps for maintenance, leakage and drainage, etc.), thermal power plants (pumps for industrial, domestic, and fire fighting, etc.), steel plants (pumps for circulating cooling, daily life, iron pits, etc.) ), agricultural irrigation, fire protection, municipal administration and other industries.

Internal structure of long shaft deep well pump

1. Motor: Hollow shaft motor for deep well pump (YLB type)
2. Adjusting nut: adjust the axial amount of impeller;
3. Pump seat: bear heavy load, and easy to install stuffing box;
4. Pre-lubrication plug: before starting, inject clean water through this place to lubricate the internal bearings of the water pump;
5. Upper short pipe (short pipe B): using flange connection, the upper flange of the short pipe is connected with the pump base, and the lower flange is connected with the flange of the pumping pipe;
6. Impeller shaft: 2Cr13 stainless steel or 45# high-quality carbon steel (chrome-plated surface);
7. Middle shell: smooth runner, reduce frictional resistance and improve efficiency. Material: HT200, QT450, 2Cr13, 304, 316, etc.;
8. Impeller: Designed in conjunction with the middle shell, high efficiency, wide operating range, and precise calibration and balance to ensure smooth operation. Material: HT200, silicon brass, QT450, 2Cr13, 304, 316, etc.;
9. Middle shell bearings: copper bearings, wear-resistant rubber bearings or imported polymer bearings. Reliable work and long life.
10. Cone sleeve: reliably fix the impeller on the impeller shaft.
11. Lower shell bearing: copper bearing, grease filling, long-term trouble-free operation.
12. Lower shell: guide the liquid in the water filter to the impeller evenly with minimal loss. Material: HT200, QT450, 2Cr13, 304, 316, etc.;
13. Water filter: The length of the water filter should be appropriate to achieve a good condition and prevent large particles from entering the pump;
14. Drive shaft: high-strength carbon steel, chrome-plated on the bearing surface. According to needs, stainless steel material can be provided;
15. Lifting water pipe: The water lifting pipe can be installed with threaded connection or flange connection.
