6"7'' 8"10"12''inch deep well submersible pump

 

1.Product overview:

QJ series deep well submersible pump is a kind of Water -lifting machine with submersible motor and submersible pump intergrated directly into one set,working deep into the water.It is mainly used in the feeding and draining engineering of farmland irrigation,city,industry and mine establishments.

 

2.Main purpose:

Lift water from deep well and sea.

Drain water from pool,river.

Water supply for skyscraper

 

3.Material

Bowl: Cast iron

Impeller: Cast iron or copper

Motor shell: Cast iron or stainless steel

Shaft: cast steel

 

4.Use condition:

1.380V bias voltage doesn't exceed ±5% and 50Hz frequency,and the deviation is not more than ±1% of the three phase power supply.

2.The inner cavity of the motor must be filled with water.

3.The first stage impeller of the pump should be immersed into the dynamic water level at least 2m.And the electric pump unit under the static water level should be within 70m.The distance from the motor bottom to well bottom must be more than 3m.

4.The temperature of the water should be within 20°c.

5.In the water,there are only 0.01% of sand (by weight) or less .

6.The PH valve of the water shoubld be between 6.5 and 8.5.

7.The hydrogen sulfide level in the water should be 1.5mg/L or less.

8.The choride ions content in the water should be 400mg/L or less.

9.Water which is yield from the water source should meet the necessary of the pump's continue working.

 

5.Structure explanation:

1.Submersible electric pump is composed of five parts: water pump,submersible motor,water line,waterproof cable and control switch. Water pump belongs to single suction multistage vertical centrifugal pump.

2.Submersible motor adopts water-filled wet structure,internal chamber was filled with water for cooling the motor and lubricating the bearing.In the operation,due to the changes of temperature,the pressure of the filled water in the internal chamber also changes,it can be automatically regulated by pressure-regulating unit in the lower part of motor.

3.For preventing the sand getting into the motor,the sand-preventing unit including sand slinger and skeleton oil-sealed was installed in the upper part of motor,the whole motor was sealed tightly.

4.There are water injection hole and exhaust hole in the upper part of the motor and discharge hole in the lower part.

5.There are thrust bearing and thrust collar,mainly for sustaining remnant axial force of pump and the empty weight of motor's rotor.

6.The winding of motor stator adopts water-proof electromagnetic wire with good insulating and water-proof functions and rotor adopts squirrel-cage structure.

7.When used in the environment where there are large grittiness or corrosive water,it should adopt the submersible pump made from casting stainless steel or copper alloy.
