In order to ensure the normal operation of deep well submersible pump unit, reducing the failure rate, long life, usually must strengthen the deep well submersible pump repair and maintenance on a regular basis submersible pump and control system, a comprehensive maintenance, at least once a year full preventive maintenance.

          Submersible pumps need attention Maintenance as follows:

          1, the use of the environment deep well pump unit should always be kept dry. Vertical motor surfaces should be kept clean, the air inlet should not be hampered dust, fibers and other debris to ensure duct obstruction. Motor should not be placed around the heat source, but also try not to use in the outdoors in direct sunlight, so as not to damage the operation of overheating.

          2, deep well pump system operation, should always pay attention to the readings on the instrument, and the timing of the pump running records related parameters (such as motor voltage, current, insulation resistance; pump flow, head, etc.) and run time.

          3, the operation if there is any unusual sound, should be immediately stopped to check. Such as found in the motor stalled anti-reverse device must be maintenance, clear the dirt, so that it can work well.

          4, when the motor control device overcurrent protection or continuous short circuit protection action occurs, the fault should be checked from motor overload protection device or customize too low. If you are setting the value of the protection device is too low, the setting value should be adjusted to a reasonable protection device value; if it is caused due to motor overload, the reason should be checked in the motor overload, overload fault elimination before running again.

          5, each run for some reason when you stop, you should be careful to check the oil level in the subject of motor oil, such as found in the oil level is lower than half the oil the subject, should be added the new oil, in order to ensure that the motor angular contact ball bearings and reliable lubrication.
