Submersible pump use, sewage pump use, submersible sewage pump use
Before using the operation of submersible sewage pump, should be submersible sewage pump, cable and control cabinet switches and other related equipment to conduct a comprehensive and careful inspection.
Specific submersible pumps are used as follows:
1, the use of submersible sewage pump, you should carefully check the submersible sewage pump chassis in the transport process whether to break into the water after the water into the water, the cable without damage caused by leakage accident, confirm the application of resistance meter check submersible pump The insulation resistance of the motor to ground is generally above 50 ~ lOOMΩ. When the measured cold insulation resistance value is less than 1MΩ, should check the stator winding insulation resistance reduction reasons, troubleshooting, so that the insulation resistance can be used to return to normal, otherwise it may cause diving motor stator winding damage.
2, the use of submersible sewage pump should be installed before the special leakage leakage protection switch or specifications match the overload protection switch to make the submersible sewage pump in the event of failure, can be reliable and effective protection without damage to the diving motor Stator windings, and even the entire motor.
3, the use of submersible sewage pump before the shell should be reliable grounding, submersible sewage pump leads to the cable core with a ground mark of the yellow-green two-color ground wire should be reliable grounding. If the conditions are limited, there is no fixed ground, you can near the power supply or submersible pump near the location of the wet land buried in the deep 2m metal rod as a ground.
④ Before using the submersible sewage pump, check whether the inside of the motor or the sealed oil chamber is filled with oil. If it is not filled in accordance with the regulations, it shall be filled with the specified oil level.
⑤ submersible sewage pump should be vertical hoisting, do not use the horizontal (except horizontal submersible sewage pump), should not fall into the mud, to prevent damage caused by poor motor cooling.
⑥ submersible sewage pump should generally not dehydration operation, if the test run on the ground, the dehydration operation time should generally not exceed 2min.
380V submersible sewage pump before use, should check the direction of rotation is correct, such as submersible sewage pump after the start of a small amount of water, indicating that the reverse, should immediately stop, for submersible sewage pump leads to any two lines of cable or line wiring position.
