Product introduce:

Zhonglan QJ submersible pump is a water machine with direct connection between motor and pump,which is suitable for extracting underground water from deep wells,and also used for carrying waters from rivers,reservoirs and canals. It is mainly used in farmland irrigation and human and livestock in plateau mountainous areas, and also for water supply and drainage in cities,factories,railways,mines and  construction sites.

Product characteristics:

1.The motor and the pump are integrated,and are submerged to run safely and reliable under water.

2.There is no special requirements for well pipe and lift pipe(that is: steel pipe well,gray pipe well and earth well can be used; under the pressure permission,steel pipe,rubber pipe and plastic pipe can be used as lift pipe)

3.Easy to install,use,maintain,occupy small areas, no need to build pump house.

4.Simple structure,saving materials。Whether the submersible pump using conditions are appropriate and management properly are directly relatively to the pump service life.

Use conditions:

1.The inlet of the pump must be less than 1m below the dynamic water level,but the submerged depth should not exceed 70m below static water level,and the distance from the bottom of the motor should be less than 1m from the bottom of the well at least.

2.The rated power less than or equal to 15kw(25kw when the power supply allows) motor start at full voltage.

3.The rated power over 15kw,the motor start at reduction voltage.

4.The use environment must comply to the specified conditions.

Zhonglan Deep well pump Performance parameters:
1.Flow range:5-2200m3/h

2.Water head range:2-1500m

3.Power range:3-3000kw(secondary speed motor,can be customized four-stage/six-stage motor)

4.Rotating speed:2900 rpm、1450rpm(secondary speed motor,four-stage speed motor)

5.Materials options:HT200、304，316，316L、tin bronze

Remarks:
1.During the pump running,pls often check the current,voltmeter and water flow ,ensure the electric pumps run under the rated conditions.

2.The valve should be used to adjust the flow and water head range,must not be overloaded. In any of the following situations the operation should be stopped immediately:

（1）When the current exceeds 20% of the rated current at the rated voltage.

（2）When the voltage is too high or too low(above 400v or under 360v)

（3）Under rated water head range,the flow decreases more than normal

（4）When the insulation resistance is less than 0.5ΜΩ

（5）When the dynamic water level drops to the pump inlet.

（6）When electric equipment and circuits are out of order.

（7）When there is sudden sound or large vibration.

（8）When the protection switch trips frequently.
