QY oil-filled submersible pump use precautions

Qy oil-filled submersible pump is the majority of farmers, industrial and mining enterprises widely used in power irrigation and drainage equipment. The pump for agricultural irrigation and drainage, garden irrigation, fountain water supply, underground water, water towers water, urban construction, industrial and mining enterprises such as water supply and drainage. The series of pumps compact structure, light and easy to move, bearing lubrication conditions are good, low noise, long life. Double-end integral seal, durable, safe and reliable
Qy oil filled submersible pump Note:
1, submersible pump specifications performance should be consistent with the actual use of the situation 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, submersible pump live or pumping work, do not wash things in the vicinity, swimming or work, do not let the animals in the vicinity of the water, to prevent electrical leakage in case of electric shock accident occurred.
5, submersible pump can not smoke a large amount of water or mud water.
6, submersible pump suddenly does not turn, or a sudden reduction in water and other abnormal phenomena, to be shut down inspection, be sure to cut off the power, and then removable disassembly.
7, 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.
8, 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.
9, 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.
10, lead out 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.
11, 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.
12, 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.
13, before use should be idle on the land 1min0, check the pump is running properly, steering is correct.
14, 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.
15, the pump should not be caught in the mud, not horizontal, it is recommended to use the external pump basket or wire basket to prevent water miscellaneous debris pump impeller.
16, after the start of the pump, such as the water is found to be small or no water, indicating that the direction of rotation of the pump is reversed, should cut off the power, the three-phase core in any two-phase exchange and then drive.
