With the rapid development of China's modernization, although the power supply has been greatly improved, the waste of energy is still quite amazing. According to relevant statistics, the installed capacity of fans and pumps in China is more than 100 million KW, and the power consumption accounts for about 30-40% of the total power consumption in China. Due to the characteristics of the working mechanism of the fan and water pump, the working motor operates at constant speed, and the air and water flow required by the work is often in variable working conditions. Moreover, when many units carry out system design, the capacity design is too large and the system matching is unreasonable. It is often "big horse pulling small car", resulting in the operation efficiency of the fan and water pump is only 30-50%, which not only has high operation cost, And wasted precious electric energy. Therefore, the energy-saving work of fans and pumps is of great significance to the development of national economy. Let's learn more together with aozhuo technology, a frequency converter manufacturer!
Combined with the working characteristics of the fan and water pump, the fan / water pump power-saving control cabinet adjusts the input frequency of the fan and water pump motor according to the requirements of the production process, changes the motor speed, reasonably adjusts the gas and liquid flow, flow rate and pressure according to the production and process needs, and replaces the backward way of adjusting the wind shield of the fan or the opening of the water pump valve, so as to optimize the production process, It can also save 20% - 50% of electric energy.
Product features
1) Excellent soft start and soft stop functions, reduce the starting current of the motor, reduce the impact of impulse current on the power grid, protect the motor and prevent the water hammer effect of the water pump;
2) Optimize the production process to make the gas and liquid flow, flow rate and pressure more reasonable; The system adopts closed-loop control, the parameter overshoot has a small fluctuation range, and the acceleration and deceleration can be automatically adjusted according to the process requirements;
3) Perfect fault detection, diagnosis and digital display functions to improve the reliability of motor operation;
4) Users can choose to switch with or without "city / power saving", which is convenient to operate;
5) It has RS-485 interface for remote automatic control, which can be used for remote control;
6) It has perfect protection functions such as short circuit, overload and overheating;
7) Good power saving effect, inconsistent according to the on-site process requirements, and the power saving rate is 0% - 50%.
