Agricultural deep well submersible pump

Agricultural deep well submersible pumpSQS, 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. 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.SQY use conditionsSubmersible 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.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 first-class 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.
