Background
The submersible pump is generally a pump in which an electric motor is completely immersed in water to pump liquid, and has a relatively simple structure. A deep well pump, also known as a long shaft pump, refers to a combined pump in which a motor or prime mover is connected to a pump body by a relatively long pump shaft above the pump.
In offshore oil platform design, it is common practice to use submersible pumps as seawater lift pumps for seawater systems and deep well pumps as fire pumps for platform fire protection systems.
At present, vibration detection is carried out on a platform regularly, however, no matter the platform is a sea water pump or a fire pump, because impellers of the pump are dozens of meters underwater, a plurality of long shafts are connected between the impellers, the vibration detection at a bearing support of a platform deck cannot directly reflect the real working conditions of the impellers and a motor of the underwater pump, and therefore the actual running state of the pump can be known only when the pump is damaged to the later stage and even secondary indirect faults occur.
The insulation detection of the offshore platform on the motor is not taken as a conventional detection means, and generally, the insulation detection is carried out after the motor goes wrong, and the insulation of the motor cannot be effectively monitored in a normal working state. The measuring method is to cut off the power of the motor, remove the power line and then use the megger to carry out the insulation test of the three-phase line to the ground, and the measuring method is also troublesome.
In addition, the pressure gauge is arranged at the outlet of the water raising pipe, so that the change of water pressure can be displayed in real time, and whether the water raising pipe has faults such as leakage or not can be indirectly judged, but the comparison function of recording and historical data is lacked.
If a suspected fault is found or the working state of the pump changes, the type of the fault and the operation trend of equipment cannot be directly judged, and the subsequent working time of the underwater deep-well pump cannot be directly determined. Therefore, the fault of the equipment can be accurately determined only by lifting the equipment.
The existing method has several defects for the maintenance and equipment management of the underwater deep well pump,
(1) the failure of the equipment cannot be accurately determined;
(2) the workload of the lifting operation is large, and the time and the labor are wasted;
(3) the time for eliminating the fault is slow, and the efficiency is low;
