The range of use of submersible sand pumps is relatively wide, because the long-term working environment is relatively harsh, so the submersible sand pumps must be inspected before use, and the specific items to be checked, our technicians have many years of operating experience, Summarized the following points:
1. Check whether the cable of the submersible sand pump is cracked or broken. Before using it, you should observe the appearance of the cable, and check the cable passage with a multimeter or megohmmeter. There must be no oil leakage at the cable outlet.
2. Before the submersible sand pump is used or placed in standby for a long time, the insulation of the stator to the shell should be measured with a megohmmeter not lower than 1MΩ, otherwise the motor winding should be dried to improve the insulation level. The insulation resistance value of the submersible pump when it leaves the factory generally exceeds 50MΩ during cold measurement.
3. Check if the submersible sand pump is leaking oil. Submersible sand pumps are prone to oil leaks: cable junctions, seals at the oil filling screw in the seal chamber, and O-ring seals at the seals. Check to see if there is a real leak. The cause of the oil leakage at the refueling screw is that the screw is not tightened or the oil-resistant rubber gasket under the screw is damaged. If it is determined that the O-ring seal leaks oil, it is mostly because the O-ring seal has failed. At this time, the submersible sand pump must be disassembled and the seal ring replaced.
4. Before using the submersible sand pump for a long time, the pump casing should be disassembled, and the impeller should be started before starting to prevent the parts from rusting and starting without water, which will burn the motor windings.
