LJC multistage deep well vertical turbine pump 400LJC550-27*3 Description

Multistage Submersible Vertical turbine pump

LJC series long shaft deep well pump adopts advanced hydraulic model and structural design, and adopts many new technologies such as core making with Ashland resin process and epoxy coating of blade passage parts. Pump high efficiency, performance curve without hump, high efficiency area is broad, efficiency is 2% to 8% higher than JC, JD type long shaft deep well pump. The pump adopts sand rejection device, and the labyrinth structure prevents sand particles from entering the bearing. The radial runout of the blade shaft, drive shaft and motor shaft is controlled within the American standard 0.13mm, the pump runs smoothly and the noise is low. Pump seat with beautiful shape, large window, easy maintenance, replacement of packing.

application range

LJC type long shaft deep well pump is widely used in water plant, hydropower station (maintenance, leakage and drainage pumps, etc.), thermal power plant (industrial, life, fire pump, etc.), iron and steel plant (circulating cooling, life, iron pit pumps, etc.), agricultural irrigation, firefighting, municipal and other industries.

Internal structure

1. Motor: deep well pump special hollow shaft motor (YLB type), or solid shaft ordinary vertical motor.

2. Adjust nut: Adjust blade wheel axial series quantity.

3. Pump seat: bear heavy load, and easy to install packing box.

4. Pre-lubrication wire plug: before starting, clean water is injected through the place to lubricate the inner bearing of the pump.

6. Upper short pipe (short pipe B) : the upper flange of the short pipe is connected with the pump seat, and the lower flange is connected with the flange of the water lifting pipe;

9. Impeller shaft: 2Cr13 stainless steel or 45# high quality carbon steel (chrome-plated surface);

10. Middle shell: smooth flow channel, reduce friction resistance, improve efficiency. Material: HT200, QT450, 2Cr13, 304, 316, etc.;

11. Impeller: with the design of the middle shell, high efficiency, wide operating range, and precision balance, to ensure smooth operation. Material: HT200, silicon brass, QT450, 2Cr13, 304, 316, etc.

12. Middle shell bearings: copper bearings, wear-resistant rubber bearings or imported polymer bearings. Reliable operation, long service life.

13. Cone sleeve: the impeller is reliably fixed on the blade shaft.

15. Lower shell bearing: copper bearing, grease filled, long-term trouble-free operation.

16. Lower shell: the liquid in the filter network is uniformly channeled to the impeller with minimum loss. Material: HT200, QT450, 2Cr13, 304, 316, etc.;

17. Water filter network: the length of the water filter network should be appropriate to achieve a good condition and prevent large particles from entering the pump.

18. Drive shaft: high strength carbon steel, bearing position surface chrome plated. Stainless steel material is available on demand.

22. Lifting water pipe: Lifting water pipe can be installed by thread connection or flange connection.
