Sewage Stations and Their Use
Sewage stations with pumping equipment are designed for the collection and transportation of wastewater and waste. They are actively used in individual houses, industrial enterprises, small populated areas with cottages, as well as in cities with a population of less than 500,000 inhabitants.
Application in Individual Houses
In private homes, sewage stations are used to pump wastewater from premises located below the level of the sewage system exit, such as basements, cellars, and garages. Such facilities include baths, pools, saunas, and other engineering systems that consume a large amount of water.
Advantages of Using Frequency Converters
The implementation of a Bosch frequency converter or a soft start device in a sewage-pumping station solves many problems and significantly increases the service life of pumping devices. Let’s consider the main problems and possible solutions:
- Problem: If the startup current exceeds the specified limits, a large cross-section cable must be used, which leads to transient processes and can damage the starting equipment.
Solution: Install a Bosch frequency converter or a soft start device, such as the Altistart model, which can avoid high starting currents, preventing overloads and shocks during startup.
- Problem: Hydraulic shocks caused by the starting and stopping of pumps negatively affect the fittings and pipes.
Solution: Using a frequency converter or soft start device will eliminate or reduce the force of hydraulic shocks, extending the service life of the equipment and decreasing repair costs.
- Problem: If air enters the pump unit, it can overheat and break down.
Solution: Implementing load control functions that ensure automatic stopping of units in emergency situations.
- Problem: Changing technological parameters, such as flow rate or pressure, without adjusting the motor speed leads to excess energy consumption.
Solution: Connecting a frequency converter Bosch VFC3610 with PID control function that will allow adjusting the electric motor speed according to the pressure level, reducing energy consumption and operating costs.
Conclusion
The application of modern technologies, such as frequency converters and soft start devices, significantly improves the efficiency of sewage-pumping stations, increasing their reliability and reducing maintenance costs.
