agricultural irrigation deep well submersible pump

SQS,SQY, SQJ Series submersible pumps widely used in farmland irrigation, spray irrigation and water-use, industrial and civil buildings, also the drainage system to level hills, mountain diversion and in low-lying areas dunes, urban and rural mining supply, drainage and other water conservancy facilities. Characteristics are that they are assembled into a simple structure they have installation convenience a small footprint, simple maintenance and a safe reliable operation.

1.SQS use conditions

(1) Power: 50 Hz frequency and voltage of 380 volts (allowing deviations +5% -10%) of the three-phase AC power. Pumps should be safe submerged operations, diving depth of not less than 0.5 meters.

(2) Water: general corrosion without water, sand volume is not 0.02%, PH: 6.5 ~ 8.5, extracting the water temperature no higher than 30 ° C.

(3) Before the use of motor cavity must fill water, no running water.

2.SQY use conditions

Submersible pumps submerged depth of not more than 5 m; Water temperature does not exceed 40 ° C; water sediment or water insoluble solid mark of the volume ratio of not more than 0.1%, particle size less than 0.2mm, no corrosion, water pH value of 6.5 ~ 8.

3.SQJ use conditions

(1) 380 V bias voltage does not exceed + -5% and 50 HZ frequency, and the deviation is not more than + -1% of the three-phase power supply.

(2) Electrical cavity must be filled with water.

(3) The firstclass pump impeller should at least go into the dynamic water level 2 m below surface. Static pump unit immersed under water shall not be greater than 70 m.

(4) Electrical from the bottom of the bottom of the well shall be not less than 3 m.

(5) The water temperature no higher than 20 ° C, QJR-temperature hot water pump up to 80 ° C.

(6) Water and sand content (by mass) of not more than 0.01%.

(7) Water PH 6.5-8.5.

(8) The hydrogen sulfide in water content is not more than 1.5 mg / L.
