Water Intake and Water Supply Automation
The main amount of water for drinking and technical needs is provided through the use of water intakes from artesian wells. Water extraction is carried out using specialized pumps, such as submersible pumps of the ECV brand, as well as foreign models. It is worth noting that foreign pumps are characterized by high safety, excellent technical specifications, but they also come with a high price.
One of the most common means ensuring automation and control of water supply is the control and protection station. It automatically turns the pump on and off depending on the pressure level and performs diagnostics of emergency situations.
Modern technologies have allowed for the automation of technical devices, but equipment with manual control is particularly popular. In such systems, thermal protection for the pump is often even absent. The low cost of such systems can lead to ongoing expenses: for equipment repairs, replacement parts, and also for paying workers' salaries. Expenses can be minimized by making the right choice of protective and control means for the pumps.
However, protective means cannot guarantee 100% protection, as the quality of power supply is very important in this matter. Due to frequent interruptions in water supply, the pump is forced to operate under uneven voltage, which leads to a reduction of its resource. This problem can be solved by using frequency converters.
Water Supply Systems and Their Features
The simplest water supply systems deliver water directly to the consumer. In such cases, pressure regulation is not performed, and if it is done, it is only through valves or manual start. To enhance reliability, the installation of frequency-regulating automation and recommended sensors that allow:
- increase the reliability of the system;
- ensure accurate setting of water levels;
- turn on additional pumps;
- activate emergency alarms.
Disadvantages of Water Towers
Today, water towers are considered an economically unviable solution that has significantly aged. The main disadvantages of water towers are:
- freezing of the inner surface;
- overflows and problems with turning pumps on and off.
Problems of Existing Water Intakes
The majority of pumping stations are equipped with energy-saving systems that regulate frequency and allow for the reduction of water and electrical energy consumption, as well as increase the equipment's service life.
The main disadvantages of water intakes that are not equipped with automated systems are:
- lack of economic pressure regulation;
- unevenness and interruptions in water supply.
These problems can be solved by introducing frequency converters and automated control systems. Such modernization will have a short payback period and will become one of the most profitable investment options in the water supply sector.
