Mine Submersible Pump Fault Analysis and Solutions

Mining submersible pump is to transport liquid or liquid pressurized machinery. All equipment in operation, more or less the inevitable failure and damage, resulting in normal pumping. What is needed is that there should be a corresponding treatment in the event of a malfunction. The following is a list of troubleshooting and troubleshooting methods for several common mining submersible pumps.

    1, can not absorb water:

    Failure Analysis: There may be due to the body of air or water intake pipe gas, or the bottom valve is not strict Irrigation irrigation water dissatisfaction, vacuum pump filling serious leaks, gate valve or shot closed lax.

    Solution: first pressure on the water, then the pump filled with water, and then boot; check the check valve is tight, piping, fittings leaks; check the pump shaft seal ring, such as serious wear and tear should be replaced Pieces.

    2, lack of traffic:

    Failure Analysis: power speed does not support or belt slippage, so that the speed is low; axial pump blade mounting angle is too small; lack of head, the pipe is too long or the pipe has a right-angle bend.

    The solution: to restore the rated speed, clear the belt grease, adjust the belt tightness; adjust the blade angle, reduce the pump installation position, shorten the pipe or change the pipe curvature; seal the pump leak, compaction packing; Change the impeller; replace the leak ring, plug the leak.

    3, violent vibration:

    Failure Analysis: Electric rotor may be unbalanced, or poor coupling, bearing wear and tear may also be rotating parts loose, rupture; may be due to the pipe bracket is not strong and so on.

    The solution: Respectively to adjust, repair, reinforcement, straightening, replacement and other methods to deal with.

    When mine submersible pump found fault, we must promptly identify the problem, correct troubleshooting. Diving work, mainly mechanical and electrical integration of new drainage equipment, by the water-filled high-pressure diving motor and multi-stage centrifugal pump into one, dive into the water run. Low requirements for the installation of environmental conditions, Li and dual, can be placed in a suitable place for drainage under local conditions. Analysis and resolution of its failure can not only improve the competitiveness of products, but also can improve work efficiency.
