Submersible pumps for iron ore
This pump does not produce axial force,the flow can achieve 50m3/h to 500m3/h,and the water head can achieve 300m,400m,500m,600m,700m,800m,900m,100m,with efficiency 70%
Product introduction:
Although the traditional QJ series pumps can achieve high lift,but the axial force is large, operation is unstable,the general life iS 2-3months. If used in the mine pump,it is not durable,and the appearance is long and thin, It’s unconvenient no matter from the installation ,transportation and other aspects. Reasons:the main reason why the submersible pump with high lift is limited in the lift is that it cannot overcome the axial force,that is the thrust bearing of the motor can not bear more the lift is limited.
This pump does not produce axial force,the flow can achieve 50m3/h to 500m3/h,and the water head can achieve 300m,400m,500m,600m,700m,800m,900m,100m,efficiency 70%
Zhonglan Submersible pumps for iron ore characteristics:
motor and the pump are integrated and immersed to run under water,no sparking ,explosion proof,reliable and safe.
is no special requirement for well pipe,as long as the pipe can bear the corresponding pressure.
to install and maintain,occupy small areas,no need to build pump house.
structure,saving raw materials
efficiency,energy saving,high lift because of single stage, large flow,import Germany high-efficiency and energy-saving motor. motor can reach 110kw(max outside diameter 132mm),secondary speed(2900/minute) can reach 410kw,minimum outside diameter can reach 134mm
Use conditions:
and short,large flow,high water head,no axial force,convenient transportation,suitable for mine pump
water from deep well and mine ,can be used for gold/silver/iron ore/coal mine emergency rescue,and drainage of construction site.
product has a small flow and high lift submersible pump:, water head range 1000m,power is 140kw,it can not only save energy,but also solve the difficult problem of underground drainage in mines, it is also suitable for mine life drinking water.
motor and pump are integrated and immersed to run under water,no sparking,explosion proof,reliable and safe.
is no special requirement for well pipe and mine well,as long as the pipe can bear the corresponding pressure.
to install and maintain,occupy small areas,no need to build pump house.
Remarks:
always check the current,voltmeter and water flow during pump running ,ensure the pumps run at the rated conditions
valve should be used for adjusting the flow and water head range,overloaded is not allowed,in any of below situations,should stop the pump immediately:
（1）When the current exceed 20% of rated current at the rated voltage.
（2）When the voltage is too high or too low(above 400v or below 360v)
（3）At the rated water head,the water flow decrease mote than normal
（4）The insulation resistance is less than
（5）When the dynamic water level drops to the outlet of the pump
（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
