small farmland irrigation SJ model water pump

SJ-wells with submersible pumps and water pump motor is integrated directly into the water to the work of the water equipment, submersible pumps, diving motors, pipes, cables and activate the protection devices and other components. It is suitable for extracting underground water from the deep well, can also be used for rivers, reservoirs, drains and other water projects mentioned, mainly used in irrigation and water for people and livestock in the mountain plateau, also for the cities, factories, railways, mines, the use of the site for drainage.

Characteristics of submersible pumps with QJ well

QJ-type submersible submersible submersible submersible pump, with a compact structure, small size, light weight, installation, use, easy maintenance, safe and reliable transportation, energy conservation and other advantages.
  1, motor, pump, sneak into the water to run, safe and reliable.
2, on the well pipe, Yang Shuang no special requirements (ie: steel pipe wells, ash pipe wells, soil wells can be used).
3, installation, use, easy maintenance simple, small footprint, do not need to build pump room. Simple structure, saving raw materials.
4, submersible pump use of the conditions are appropriate, proper management and life have a direct relationship.
5, power supply for the 50 Hz 380 V three-phase AC.
6, the first stage of the pump should be submerged into the moving water level below 1 meter, the bottom of the motor from the bottom of the well is not less than 3 meters, but the depth of water into the water is not greater than 70 meters.
7, the content of solids in water (by mass) is not greater than 0.01%.
8, water pH value in the 6.5 ~ 8.5 no corrosion.
9, the water temperature is not higher than 20 ℃.
10, the wells should be straight (to be able to install in place and can be smooth to prevail, if the skew more powerful, well diameter should be slightly larger or choose a small one-caliber pump).
11, wells must have sufficient gushing (ie greater than rated flow).

QJ deep well submersible pump Purpose

QJ deep vertical multi-stage pump is suitable for extracting groundwater from deep wells and can also be used for water lifting projects such as rivers, reservoirs and canals. It is mainly used for farmland irrigation and manure water in plateau mountain areas. It is also available for cities, factories, railways, Site for drainage use.
