Submersible electric pump for well QJ product instruction
QJ type submersible pump motor and pump directly connected together the water pump into the water to work, it is suitable for theextraction of groundwater from wells, can also be used in rivers,reservoirs, canals and other water projects: mainly used for irrigation and plateau mountain water for people and livestock, but also for the city, factory, railway, mine the site use, water supply and drainage.
Submersible electric pump for well QJ product illustration
1, Motor, pump body, into the water to run, safe and reliable.
2, The well pipe, water pipe and no special requirements (i.e.: steel tube well, well, Doi ash can be used in pressure; under license, hose,steel pipe, plastic pipe can be the Yang water use).
3, Installation, use, convenient and simple maintenance, small occupation area, without the construction of pumping stations.
4, Has the advantages of simple structure, raw material saving.
Submersible electric pump for well QJ use condition
Type QJ wells with submersible pump can be run continuously used in the following conditions:
1 .The rated frequency 50HZ, rated voltage of the three-phase AC power supply of 380 ± 5%V.
2 .Water inlet of the water must be in dynamic water level 1 metersbelow, but the diving depth shall not exceed the static water levelbelow 70 meters, the lower end of the motor from the bottom depthof at least 1 meters.
3 .General shall not be higher than 20 ℃ temperature.
4 .Water quality requirements: (1) the water sand content of not more than 0.01% (weight ratio);
(2) the pH in the range of 6.5~8.5;
(3) the chloride ion content is not more than 400 mg / L.
5 .Well as, wall smooth, not well pipe.
Submersible electric pump for well QJ working principle
Before opening the pump, suction pipes and pumps must be filled with liquid. Open pump, the impeller rotating speed, which leaves the liquid together with the rotation, under the action of centrifugal force,flying away from the impeller injection, injection of the liquid in the pump shell gradually slow the proliferation of indoor speed, the pressure gradually increased, and then from the pump outlet, the outflow discharge tube. At this time, the blade center of low pressurearea due to liquid was thrown neither to the surrounding air to formand no liquid, liquid pool at the surface of the liquid under the action of atmospheric pressure, through the suction pipe into the pump, the liquid is continuously pumped up from the liquid pool is also a continuous from the outflow discharge tube.
Submersible electric pump for well QJ scope of supply
