The inspection of a rotating installation is the basis for of good maintenance and further monitoring – Van Meer reports on its observations and advises its customers on future action
Pump inspection on location
Van Meer advises a full electrical and mechanical investigation during a pump inspection. The condition of the different components is controlled and assessed to be able to provide the right advice and the necessary support for a pump overhaul, maintenance or repair.
Visual pump inspection
During a visual check of the equipment we inspect the condition based on noise level, temperature and visible leaks. Checking the oil and lubricant level are also important points. If possible all packing can also be checked, as well as the mechanical seals for leaks or soiling.
Vibration and spectrum analysis of pumps
A condition measurement is carried out on the different components: the pump and electric motor. It is checked whether there is mechanical (starting) damage such as wear, imbalance, bearing damage or alignment faults.
Electrical motor pump measurement
Testing the electrical circuit in an electric motor identifies any electrical anomalies in the motor (pump) part:
- Deviation in phases, insulation value within tolerance
- Earth faults
- Presence of moisture in the motor
Control of pump alignment
At the start of the inspection as-found alignment will be carried out on the pump motor. In so doing, aspects including the wearing of coupling, seals and rubbers can be detected, as can any loss of energy due to increased friction. When the equipment is presented for overhaul, the as-found alignment can be used for correct positioning and alignment again (as-left).
Pump impeller balancing
A pump impeller balance check prevents any imbalance from occurring. If a large imbalance is nevertheless established, the pump impeller must be thoroughly cleaned or it can be replaced by a new one when deterioration due to corrosion too great.
Pump inspection result
The full inspection creates a clear separate picture of each item of equipment (electric motor – (coupling) – pump) and of the equipment in its entirety (motor pump). Depending on the results it can be specifically determined what concrete action is required to have the equipment work optimally and reliably as a whole. This can for example be alignment, an overhaul or a repair at our workplace. A clear report with photos and explanation is also always supplied and discussed.
