QJ type submersible pump is from the deep well groundwater extraction in complete sets of equipment, widely used in agricultural irrigation, industrial and mining enterprises for drainage and highland, mountain with water. QJR type well water pump, using special materials and structure, used for the extraction of underground hot water. In addition the company produced according to user needs water, mining and other special occasions with submersible pump. The pump is host by QJ type submersible pump and YQS type submersible pump machine. Underwater work, has the advantages of compact structure, small volume, light weight, installation, using, convenient maintenance, safe and reliable transportation, energy saving etc..
1, power: three-phase alternating current, voltage 380 volts, a frequency of 50 hz.
2, water source
( 1) the water temperature a:QJ≤20 ℃ b: QJ≤ 20 ℃
( 2) of sediment concentration in water ( weight ratio) shall not exceed 0.01%, chloride ion may not exceed 400 mg / l..
( 3) PH=6.5 ~ 8.5150QJ ( R ) 10-150
150 application of minimum hole diameter 150 mm:
QJ ( R ) model features: wells with submersible pumps ( water )
10 of the rated flow: 10 cubic meters / hour
150/ rated head: 150 meters
QJ type submersible pump is composed of multi-stage centrifugal impeller section connected in series. Pump stage consists of a flat lacing or bolt connection, between each segment is made of rubber ( or copper ) bearing support, pump peak without check valve. YQS type submersible motors for hermetic filling water type three-phase asynchronous motor, winding adopts water continuous sealing structure, guide bearing and thrust bearing are water lubricated bearing; the motor is mounted on the upper part of sand bodies, prevent sediment into the motor control.
In 1, the host: submersible pump and submersible motor.
2: water pipe, tube, pipe, a rubber pad, such as installing splint.
3: cable, cable and cable joint material.
In 4, the starting and protection device.
