Thanks to the smooth speed control motor, the use of frequency converters simplifies the mechanical system and helps reduce costs. Proper acceleration of the electric motor reduces shock loads of parts and assemblies drivers, which leads to increased equipment life in general. For example, using a frequency converter HYUNDAI brand in conjunction with pumping unit saves up to 50% electricity. Using the inverter eliminates hydroblows, dramatically reduces the mechanical stress on components and machinery parts, allows you to monitor the equipment in real time. At business need can be installed remote pumping stations, making adjustments to work through the Internet, and in emergency situations – SMS informing staff on duty and archiving of key events for all time. With the idea that at different times of day water consumption, and as a consequence – power consumption differ, we can calculate the economic effect of chastotonogo converter. Let us, knowing that at different times of day water consumption in high-rise building varies in a quantitative value: increases in the morning and evening hours, decreases in the daytime and night – you can to calculate the economic effect of the inverter in a small pumping station, which works to ensure high-rise building. Calculation of the efficiency of the implementation of the system to control pumps pumping station Sosnovskaya Name Meaning dimension pumping unit to pump type 80-50-200 Rated head 50 m 50 Rated flow m3 / h Speed 2840 r / min Power consumption 10.5 kW el / dv 15 kW Nom.tok E / dv 30 A cost savings 1kVt/chas Score 2.28 USD payback calculation frequency converter: Name Quantity Unit.
ism. The savings estimated in comparison with 42% throttling throttling consumption at 360 kWh / Savings for frequency regulation of 151 kW / h payback period 0.83 years cost control box with emergency 120 000 rubles data are taken at the time of calculation: the value of kW / h is 2, 28 rubles. and measuring the magnitude of energy consumption with the use of CRP and throttling, we obtain the energy savings of 42% when using the converter, as compared to throttling. Thus, a system based on the frequency converter with an estimated value of 120 000 rubles. pays less than a year later and only works to save energy, and as a consequence – to save money the company. In addition to direct savings, we get: 1.
Increased life of equipment in the 1.5-2. 2. Savings of up to 30% vodozatrat due to the high accuracy of maintaining the schedule pressure in water supply networks. 3. Reduced wear and longer service life of process equipment, excluding hydraulic shocks. 4. Reduction repair costs. To achieve the total volume of these positive results by using the inverter, you must correctly pick up the converter itself. In this article, as an example We have led the inverter company HYUNDAI. In conclusion, we want to add that the introduction of automation in production can save on electricity costs for salaries and maintenance personnel on duty. It should be noted that these energy-efficient systems are fully compliant with 261 of the Federal Law.
