Deep well pump operation need to pay attention to what

For many people believe that deep well pump is not unfamiliar, then the operation of the deep well pump when the need to do it? The following from the Shanghai deep well pump manufacturers to talk about the use of stainless steel deep well pump.

    First of all, should be used before the stainless steel deep well pump cable and control cabinet switch lights on the equipment to conduct a comprehensive and careful testing.

    Specific use of deep well pump

    First, the use of stainless steel deep well pump, you should carefully check the stainless steel deep-well pump casing in the transport process without breaking so as not to put into the water after the motor water, cable damage caused by leakage accident, confirmed the use of resistance table check dive Pump motor insulation resistance to the ground, its value is generally 50-lOOMΩ above. When the measured cold insulation resistance of less than 1MΩ, should check the stator winding insulation resistance to reduce the cause, troubleshooting, the insulation resistance back to normal before use, otherwise it may cause damage to the stator winding of the submersible motor.

    Second, the use of stainless steel deep well before the pump should be installed a special leakage protection switch or the specifications of the overload protection switch to make the stainless steel deep-well pump failure in use, can be reliable and effective protection without damage to the submersible motor Of the stator windings, or even the entire motor.

    Third, the use of stainless steel deep-well pump before the shell should be reliable grounding, stainless steel deep-well pump cable leads with a grounding mark in the yellow-green two-color grounding should be grounded. If there is no fixed ground, the metal rod with a depth of 2 m is buried in the wet land near the power source or the submersible pump.

    Fourth, the use of stainless steel deep well pump should be checked inside the motor or sealed oil chamber is full of oil, if not filled in accordance with the provisions should be added to fill the provisions of the oil.

    Fifth, stainless steel deep-well pump should generally be vertical hoisting, not horizontal use (horizontal stainless steel deep-well pump), should not fall into the mud, to prevent damage due to poor heat dissipation of the motor.

    Sixth, the stainless steel deep well pump should not dehydrate the general movement, if needs to carry on the test operation on the ground, its dehydration movement time generally should not surpass for 2 minutes.

    Tips: 380V stainless steel deep well pump before use, should check the direction of rotation is correct, such as the stainless steel deep-well pump start after the water out of small, that turn to the contrary, should immediately stop for the stainless steel deep-well pump leads to the line or any two-phase wiring position .
