Instructions for use of oil - immersed submersible pumps

Oil-immersed submersible pump is a water pump and three-phase asynchronous motor integrated power drainage equipment. With a reliable waterproof sealing performance, small size, light weight, no pump room, no irrigation water, the use of maintenance and management are convenient.

Oil filled submersible pump working conditions

· Submersible pump submerged depth of not more than 5m:

· Water temperature does not exceed 40 ℃:

The volume ratio of the sand in the water or the solid particles containing water does not exceed 0.1% and the particle size is not more than 0.2mm:

No corrosion, water ph value of 6.5-8;

Such as the general room temperature water: well water, river, lake.

Instructions for use of oil - immersed submersible pumps

1, submersible pump specifications should be consistent with the actual performance of the use, should be carefully checked before use.

2, submersible pump with the outlet diameter should be matched with the pump diameter.

3, the power capacity should be above 5.5 kVA, three-phase, 380 volts, AC 50 Hz.

4, the pump should be equipped with motor protection switch (factory has a "protection switch action current has been set up, the user may not change their own.

5, at any time are not allowed to pull the power pump cable. When using the full inspection of the cable, found damaged immediately replaced before use.

6, the voltage fluctuation is allowed between 342 and 418 volts. Such as the use of electric distance from the power pump should be appropriate to increase the cross-sectional area of ​​the wire.

7, leads to a cable with a ground mark of the yellow-green two-color core wire must be ground, if no fixed ground, available 2 m metal rod buried in the river, lake shore, ditch or wet soil line.

8, before use should check the upper and lower cover oil hole screws are loose oil leakage phenomenon. Outlet box on the middle of the m8 screw test for the factory dedicated to prohibit users to loose their own.

9, before running with 500v megger measuring cold motor stator winding on the ground insulation resistance, the minimum shall not be less than 5mω, or can not be used, should be removed before the use of moisture.

10, before use should be idle on the land 1min0, check the pump running is normal, steering is correct.

11, the pump may not be dehydrated. In the pump work should pay attention to check the water level down, not allowed to show the pump running on the water. The diving depth of the pump ranges from 0.5 to 3 meters.

12, the pump should not fall into the mud, shall not be horizontal, it is recommended to pump external basket or wire basket to prevent water miscellaneous debris pump impeller.

13, after the pump starts, such as the discovery of a small amount of water or no water, indicating that the direction of rotation of the pump should be cut off the power, the three-phase core in any two-phase exchange and then drive.

14, submersible pump live or pumping work, do not wash things nearby, swimming or work, do not let the animals in the vicinity of the water, to prevent the electrical pump in case of leakage, electric shock casualties occurred.

15, submersible pump can not smoke a larger amount of water or mud water.

16, submersible pump suddenly does not turn, or a sudden reduction in water and other abnormal phenomena, to be shut down to check, be sure to cut off the power, and then removable
