Application Environment and Parameter Introduction of Hot Water Submersible Pump

(A) product use and main features
QJR series of hot water submersible pump for geothermal wells, for the extraction of geothermal water. Geothermal is a cheap, clean energy, widely used in heating, medical, bathing, breeding, planting, industrial and agricultural production, entertainment services and so on.
QJR series of submersible submersible submersible submersible work, with heat, corrosion, high efficiency, energy saving, easy installation and maintenance, etc., is the replacement of geothermal water equipment.
(B) the use of conditions
1, the rated power supply voltage 380V ± 5% frequency 50Hz ± 1% of the three-phase AC power supply, the motor terminal rated voltage should be guaranteed within the allowable deviation of the rated voltage range.
2, the control cabinet must have a short circuit, lack of phase, overcurrent, overload and other basic protection, and to ensure that the installation will adjust the settings to the stability of the operation, the protection of sensitive locations, the steps are very important to be professional and technical personnel debugging correctly The
3, the motor is flushing, the motor cavity must be filled with distilled water (or clean water) before installation.
4, the pump's first impeller at least invasive water level below 3 meters, the pump unit intrusion below the hydrostatic level shall not be greater than 70 meters, the bottom of the motor from the bottom of the bottom shall not be less than 5 meters.
5, select the model when the diameter and pump models to match, avoid large diameter diameter selection of small diameter pump, which is not conducive to the motor cooling.
6, the water temperature is not higher than 120 ℃.
7, the water does not contain oil substances.
8, water salinity and water quality requirements: (the main indicators of corrosive substances)
(3) material description
1, impeller: cast iron HT200 or tin bronze (various grades) such as: ZCuSn3Zn8Pb6Ni1
2, the pump shell: cast iron HT200 or stainless steel such as: 2Gr13 .304
3, the pump shaft: cold drawn steel chrome, or stainless steel 2Gr13 (1050 ℃ quenched and tempered, reinforced torque)
4, motor seal: rubber seal O-ring; machine seal
(4) the scope of application
Applicable to enterprises and institutions such as: bath, district heating, business use of geothermal energy power generation, extraction of underground high temperature hot water, according to different diameter we have different specifications for the user to choose models. The device low noise, high efficiency and save energy.
(5) technical parameters
1, to allow the working temperature range: +5 to +105 ℃
2, solid impurity content (mass ratio) is not more than 0.01%
3, PH value (pH) 6.5-8.5
4, hydrogen sulfide content of not more than 1.5mg / L
5, chloride ion content of not more than 400mg / L
6, the unit must be completely invasive water work. Vertical use, select the model when the diameter and pump models to match, avoid large diameter diameter hole selection of small diameter pump, this is not conducive to the motor cooling.
(6) motor parameters
Diving motor cable length: 3m. Such as the user needs to extend the cable can advance call us, the submersible motor for the water lubrication, before use must be filled with clean water to the motor cavity, (Note: must be filled or will reduce the motor life) If you forget to add water motor Quickly burned out.
Motor protection class: IPX8
Electromagnetic wire with high temperature waterproof line.
Power: 380V, deviation of not more than ± 5%, frequency 50HZ, the deviation does not exceed ± 1%, if the customer needs a special voltage or special frequency need to inform us in advance.
(7) the advantages of equipment
1, in the factory's careful assembly to ensure the site quickly and reliably installed.
2, the use of single-stage impeller or multi-stage impeller series, the noise is minimal. Good temperature performance, long life
3, the unit can completely break the water work, to avoid the vacuum pump is easy to use the air is not easy to use the drawbacks.
(8) Scope of supply
Hot water submersible pump unit (including the pump and the submersible motor composed of two parts), a pair of outlet flanges, 14 × 60 bolts 8. Or configure the corresponding outlet (to facilitate the user to install the hose installation) to use a maintenance manual, a certificate of 1 copies of a packing box, wooden box packaging.
