Operation Monitoring and Energy Consumption Data Acquisition System Scheme for Reclaimed Water Lift Pump Station

In the field of municipal and industrial water treatment, pressure pump stations, as a key power link, account for 35% - 45% of the total operating cost of water plants. Traditional pump stations have long relied on manual adjustment, resulting in low efficiency and frequent failures. In particular, some equipment has been in a high-load operation state for a long time, and the risk of failure and shutdown has also risen sharply, becoming an important factor affecting the safety of water supply and drainage.

A reclaimed water lift pump station is set up under a sewage treatment plant in a certain park, which is responsible for the important task of reusing the tail water in the park. However, the traditional management mode has the following pain points:

1. Low energy efficiency: High-pressure water pumps run at power frequency for a long time, with high failure risk and high energy consumption cost.

2. Chemical waste: The disinfection process relies on manual experience to add sodium hypochlorite, resulting in material waste and heavy workload.

3. Lack of operation and maintenance: The water pump motor has long been lacking in maintenance and improvement, which affects the stability of equipment operation.

In response to this, Wutong Bolian provides an efficient and reliable IoT solution, which can seamlessly connect PLC frequency converters, disinfection dosing pumps, electromagnetic flowmeters and other equipment to industrial intelligent gateways, and realize data collection into the pump station management platform (5G/4G/WIFI/Ethernet, etc.). Thus, it can realize remote monitoring, remote control, remote maintenance, fault alarm, operation and maintenance management, data analysis and other functions for pump station equipment, which helps to improve work efficiency and management level. Realized Functions

Real-time monitoring: Users can view the operation status and equipment parameters of each water pump in the water supply pump station, as well as pressure, flow, water level, etc., in real time through the large screen of the monitoring center or phones, so as to realize all-round real-time monitoring of the operation of the pump station.

Remote control: Authorized users can remotely control the water pump anywhere with a network connection, including starting, stopping, adjusting the operating frequency and other operations, so as to conveniently and quickly respond to various emergencies and different water supply demands.

Data analysis: Through visual processing of data, trend curves, reports, etc., are generated to help managers understand the operation status of equipment, find potential problems, and provide data support for equipment maintenance and optimized operation.

Fault alarm: When equipment fails, alarm information is sent to relevant personnel immediately through SMS, email, WeChat push and other methods, informing them of the type and of the fault, so that maintenance measures can be taken quickly and water outage time can be reduced.

Operation and maintenance management: Establish a standardized and visual operation and maintenance work order management mechanism, and record in real time the responsible personnel, processing progress, execution time, operation logs and other information of the operation and maintenance work order, so as to facilitate management, review and rollback operations.

Remote maintenance: Engineers can carry out remote programming and debugging of remote PLCs and remote uploading and downloading of programs without business trips, which improves work efficiency and management level, and reduces the frequency of business trips and extra expenses.
