Pump Monitoring
Pump Performance Test
The data collected - efficiency, motor input power and head can be plotted against flow to form a pump curve. The current operating curve can be compared to the manufacturer’s curve to indicate the level of pump wear. This shows how the pump is currently operating in comparison with performance after initial installation, revealing the shortfall from its optimum efficiency. This helps to identify pump wear and necessary improvements.
Multi-Pump Monitoring
Installing Yatesmeters on individual pumps within a system provides the overall station efficiency. The combinations of pumps that produce the most efficient station operation can be identified, leading to lower maintenance costs and financial savings (typically 15-20%).
Typically, monitoring takes place over several days or weeks so that the station performance can be assessed thoroughly and its full operating range is covered. Along with the report, an optimum pumping schedule is also provided for the station.
AEMS Periodic Reporting Service
A monthly report summarises all data collected so that the system operation is optimised, minimising pumping costs.
The report has three sections.
Section 1 – Inefficient Pump Usage
This table is used to show the three worst pumping events during the previous month, where the combined efficiency has fallen below the datum minimum efficiency. By highlighting these events, the causes can be identified and changes made to ensure the same mistakes are not repeated.
AEMS Ltd. work on a traffic light system of RED, AMBER and GREEN, by using this method, any immediate concerns can be highlighted and acted upon.
RED – Immediate Action Required
AMBER – Attention required in next few months
GREEN – No Action Required
This notation is used through out the report.
Section 2 – Individual Pump and System Performance
This table displays individual pump performance data with maximum and average efficiencies. The datum norm was set following the first month of scheduling and this table reflects the efficiency of the pumps and system against this norm. AEMS works closely with the operators and the datum is improved periodically reflecting continuous improvements within the system.
Section 3 – Performance Chart
The performance chart shows how the operation of the pumping plant has performed in relation to the expected optimum pump schedule.
