Oil immersed submersible pump working conditions:
Submersible electric submersible pump into the depth of not more than 5m:
The water temperature is not more than 40:
The water content of sand or the volume ratio of solid particles which does not dissolve in water is not more than 0.1%, and the particle size is not more than 0.2mm:
No corrosion, water pH value of 8 - 6.5;
Such as general room temperature water: Well, river water, Lake water.
Oil immersed submersible pump use notice
1. Submersible pump specifications should be in line with the actual use of the situation, should be carefully checked before use.
2. Submersible pump outlet pipe diameter should be equipped with electric pump and caliber.
3. The power supply capacity should be more than three, three phase, 380 volts, AC 50 hz.
4. The pump should be equipped with a motor protection switch (placing "protection switch action current have been adjusted in the factory, the user may not change their own.
5. Any time are not allowed to force pulling the cable of electric pump. When using a comprehensive inspection of the cable, found damaged immediately replaced by the new party can be used.
6. Voltage fluctuations allow between 342~418 volts. If the pump is far away from the use of power, should be appropriately thick wire cross-sectional area.
7. A lead out cable in a root with the grounding Mark Green two-color wire must be ground, if there is no fixed ground, available 2 meters metal rod buried in the side of the river, lake, near the ditch or wet soil for wire.
8. Before use should check whether the oil hole screws on the bottom cover is loose oil leakage phenomenon. Outlet box on the middle of the M8 screw for the factory trial pressure, no user to loose.
9. The operation of 500V megohm table to measure the cold motor stator windings of the insulation resistance, a minimum of not less than 5m ohm, otherwise it can not be used, should get rid of moisture can be used.
10. Before the use of the land over the 1min0, check whether the normal operation of the pump, steering is correct.
11. The electric pump shall not be dehydrated to run. In the electric pump work should pay attention to check the water level drop, must not let the electric pump dew in the water running. Electric submersible pump depth range is 0.5 to 3 meters.
12. Electric pump shall not stuck in the mud, shall not be placed horizontally, suggested electric pump topical baskets or wire basket to prevent grass debris clogging the pump impeller.
13. Electric pump start, such as the discovery of a small amount of water or not, the direction of rotation of the electric pump, should be cut off the power supply, the three-phase core wire in any two phase position to exchange for a second to drive.
14. Submersible electric pump live or pumping work, not in the vicinity of washing things, swimming or work, do not let the cattle in the vicinity of the water, to prevent the pump in case of leakage, electric shock casualties.
15. Submersible pump shall not be pumped sand containing a larger amount of water or mud.
16. Submersible electric pump does not turn suddenly, or a sudden significant reduction in water and other abnormal phenomena, must be shut down inspection, be sure to cut off the power supply, and then handling disassembly.
